The communication module  190  may include one or more communication processors that are operable independently from the processor  120  (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module  190  may include a wireless communication module  192  (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module  194  (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network  198  (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network  199  (e.g., a long-range communication network, such as a legacy cellular network, a fifth generation (5G) network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module  192  may identify and authenticate the electronic device  101  in a communication network, such as the first network  198  or the second network  199 , using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module  196 . 
     The wireless communication module  192  may support a 5G network, after a fourth generation (4G) network, and next-generation communication technology, e.g., new radio (NR) access technology.

The wireless communication module  192  may support a high-frequency band (e.g., the millimeter wave (mmWave) band) to achieve, e.g., a high data transmission rate. The wireless communication module  192  may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large-scale antenna. The wireless communication module  192  may support various requirements specified in the electronic device  101 , an external electronic device (e.g., electronic device  104 ), or a network system (e.g., the second network  199 ).

       FIG.  2 A  is a front perspective view related to an electronic device in a closed state according to an embodiment of the disclosure.  FIG.  2 B  is a rear perspective view related to an electronic device in a closed state according to an embodiment of the disclosure.  FIG.  3 A  is a front perspective view related to an electronic device in an open state according to an embodiment of the disclosure.  FIG.  3 B  is a rear perspective view related to an electronic device in an open state according to an embodiment of the disclosure. 
     Referring to  FIGS.  2 A,  2 B,  3 A, and  3 B , in the embodiment, an electronic device  200  may be implemented to expand a screen in a sliding manner. For example, a screen  230   d  may be an area of a flexible display  230  that is visible to the outside.  FIGS.  2 A and  2 B  illustrate the electronic device  200  in which the screen  230   d  is not expanded, and  FIGS.  3 A and  3 B  illustrate the electronic device  200  in which the screen  230   d  is expanded. The state in which the screen  230   d  is not expanded may be referred to as a ‘closed state’ in which a display support structure  220  for allowing a sliding motion of the flexible display  230  does not slide out. For example, the sliding-out may mean that the display support structure  220  at least partially moves in a first direction (e.g., a +x-axis direction) when the electronic device  200  is in the closed state. The state in which the screen  230   d  is expanded may be referred to as an ‘open state’ in which the screen  230   d  is maximally expanded and the screen  230   d  is not expanded any further by the sliding-out of the display support structure  220 . According to various embodiments, the open state may be defined as a state in which the screen  230   d  is expanded in comparison with the closed state. The open state may provide screens various sizes in accordance with a movement position of the display support structure  220 . According to various embodiments, an intermediate state may refer to a state between the closed state in  FIG.  2 A  and the open state in  FIG.  3 A . The screen  230   d  is an active area of the flexible display  230  that is visually exposed and may output images. The electronic device  200  may adjust the active area in accordance with a movement of the display support structure  220  or a movement of the flexible display  230 . In the following description, the open state may refer to the state in which the screen  230   d  is maximally expanded. In any embodiment, the flexible display  230 , which is slidably disposed on the electronic device  200  in  FIG.  2 A  and provides the screen  230   d , may be referred to as a ‘slide-out display’ or an ‘expandable display’. According to various embodiments, the electronic device  200  including the flexible display  230  may include the electronic device  101  in  FIG.  1   . 
     According to the embodiment, the electronic device  200  may include a sliding structure related to the flexible display  230 . For example, when the flexible display  230  is moved to a preset distance by an external force, an elastic structure included in the sliding structure may switch the state from the closed state to the open state or from the open state to the closed state without an additional external force. 
     According to any embodiment, when an input device included in the electronic device  200  generates a signal, a drive device, such as a motor, connected to the flexible display  230  may switch the state of the electronic device  200  from the closed state to the open state or from the open state to the closed state. For example, when a signal is generated by a hardware button or a software button provided through the screen, the electronic device  200  may switch from the closed state to the open state or from the open state to the closed state. 
     According to various embodiments, when a signal is generated from various sensors such as a pressure sensor, the electronic device  200  may switch from the closed state to the open state or from the open state to the closed state. For example, a sensor may detect a squeeze gesture when a part of a user&#39;s hand (e.g., palm or finger) presses a designated section of the electronic device  200  when the user carries or grips the electronic device  200 , and the electronic device  200  switches from the closed state to the open state or from the open state to the closed state in response to the squeeze gesture. 
     According to the embodiment, the flexible display  230  may include a second area   (see  FIG.  3 A ). The second area   may include a portion of the screen  230   d  that is expanded when the electronic device  200  switches from the closed state to the open state. When the electronic device  200  switches from the closed state to the open state, at least a part of the second area   may be extended from the internal space of the electronic device  200 , such that the screen  230   d  may be expanded. When the electronic device  200  switches from the open state to the closed state, at least a part of the second area   may be retracted into the internal space of the electronic device  200 , such that the screen  230   d  may be contracted. When the electronic device  200  switches from the open state to the closed state, at least a part of the second area   may move to the internal space of the electronic device  200  while being curved. For example, the flexible display  230  may include a substrate (e.g., plastic substrate) made of a polymer material containing polyimide (PI) or polyester (PET). In various embodiments, the second area   is a portion that is curved from the flexible display  230  when the electronic device  200  switches between the open state and the closed state. For example, the second area may be referred to as a bendable section. 
     According to the embodiment, the electronic device  200  may include a housing  210 , the display support structure  220 , or the flexible display  230 . 
     For example, the housing (or a casing)  210  may include a back cover  212 , a first side cover (or a first side cap)  213 , or a second side cover (or a second side cap)  214 . The back cover  212 , the first side cover  213 , or the second side cover  214  may be connected to a support member (not illustrated) positioned in the electronic device  200  and define at least a part of an external appearance of the electronic device  200 . 
     For example, the back cover  212  may define at least a part of a rear surface  210 B of the electronic device  200 . In the embodiment, the back cover  212  may be substantially opaque. For example, the back cover  212  may be formed by coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the above-mentioned materials. According to the embodiment, the back cover  212  may include a planar portion  212   a , and curved surfaces  212   b  and  212   c  positioned to be opposite to each other with the planar portion  212   a  interposed therebetween. The curved surfaces  212   b  and  212   c  may be formed adjacent to two relatively long opposite edges (not illustrated) of the back cover  212  and curved toward the screen  230   d  positioned opposite to the back cover  212 . The curved surfaces  212   b  and  212   c  may extend in a seamless manner. According to any embodiment, the back cover  212  may include one of the curved surfaces  212   b  and  212   c  or be implemented without the curved surfaces  212   b  and  212   c . In any embodiment, at least a part of the second area   may also be disposed to be visible from the outside through the back cover  212  in the state (e.g., the closed state) in which the second area   of the flexible display  230  is retracted into the internal space of the housing  210 . In this case, the back cover  212  may be made of a transparent material and/or a semi-transparent material. 
     According to the embodiment, the first side cover  213  and the second side cover  214  may be positioned opposite to each other. For example, the first side cover  213  and the second side cover  214  may be positioned opposite to each other with the flexible display  230  interposed therebetween in a second direction (e.g., y-axis direction) orthogonal to the first direction (e.g., the x-axis direction) of slide-out of the display support structure  220 . The first side cover  213  may define at least a part of a first side surface  210 C of the electronic device  200 . The second side cover  214  may define at least a part of a second side surface  210 D of the electronic device  200  that is directed in a direction opposite to the first side surface  210 C. The first side cover  213  may include a first rim portion (or, a first rim)  2131  extending from an edge of the first side surface  210 C. For example, the first rim portion  2131  may define at least a part of one side bezel of the electronic device  200 . The second side cover  214  may include a second rim portion (or a second rim)  2141  extending from an edge of the second side surface  210 D. For example, the second rim portion  2141  may define at least a part of the other side bezel of the electronic device  200 . 
     According to the embodiment, the display support structure  220  may perform a sliding motion on the support member (not illustrated) positioned in the electronic device  200 . At least a part of the flexible display  230  may be disposed on the display support structure  220 . The closed state in  FIG.  2 A  or the open state in  FIG.  3 A  may be implemented based on a position of the display support structure  220  on the support member. According to the embodiment, the flexible display  230  may be attached to the display support structure  220  based on a bonding member (or an adhesive member) (not illustrated) such as a double-sided tape. According to various embodiments, the bonding member may include a thermally reactive bonding agent or a photo reactive bonding agent. According to various embodiments, at least a part of the flexible display  230  may be inserted into a recess (not illustrated) formed in the display support structure  220  and disposed and fixed onto the display support structure  220 . The display support structure  220  may serve to support at least a part of the flexible display  230 . According to any embodiment, the display support structure  220  may be referred to as a sliding plate or a slidable support plate. 
     According to the embodiment, the display support structure  220  may include a third rim portion  2201  that defines an outer surface of the electronic device  200  (e.g., a surface that is exposed to the outside and defines an external appearance of the electronic device  200 ). For example, the third rim portion  2201 , together with the first and second rim portions  2131  and  2141 , defines a bezel at the periphery of the screen  230   d  in the closed state in  FIG.  2 A . In the closed state, the third rim portion  2201  may be extended in the second direction (e.g., the y-axis direction) to connect one end of the first side cover  213  and one end of the second side cover  214 . For example, in the closed state in  FIG.  2 A , a surface (not illustrated) of the third rim portion  2201  may be smoothly connected to a surface (not illustrated) of the first rim portion  2131  and a surface of the second rim portion  2141 . According to various embodiments, the third rim portion  2201  of the display support structure  220  is an element that defines a part of an outer surface of the electronic device  200 , and the third rim portion  2201  may be defined as a part of the housing  210 . 
     When the display support structure  220  slides out, at least a part of the second area   may come out of the electronic device  200 , such that the state (e.g., the open state) in which the screen  230   d  is expanded may be provided, as illustrated in  FIG.  3 A . 
     According to the embodiment, in the closed state in  FIG.  2 A , the screen  230   d  may include a planar portion  230   a , and a first curved portion  230   b  and/or a second curved portion  230   c  positioned opposite to each other with the planar portion  230   a  interposed therebetween. For example, in the closed state in  FIG.  2 A , the first curved portion  230   b  and/or the second curved portion  230   c  may be positioned to correspond to the curved surfaces  212   b  and  212   c  of the back cover  212  and curved toward the back cover  212 . In the embodiment, the first curved portion  230   b  and/or the second curved portion  230   c  may be eliminated. When the state is changed from the closed state in  FIG.  2 A  to the open state in  FIG.  3 A , the planar portion  230   a  may be expanded. For example, a part of the second area  , which defines the second curved portion  230   c  in the closed state in  FIG.  2 A , may be formed as another part of the second area   and included in the planar portion  230   a  that is expanded when the state is changed from the closed state in  FIG.  2 A  to the open state in  FIG.  3 A . 
     According to the embodiment, the electronic device  200  may include an opening (not illustrated) through which the second area   is retracted or extended, and/or a pulley (not illustrated) positioned in the opening. The pulley may be positioned to correspond to the second area  , and the pulley may rotate when the electronic device switches between the closed state in  FIG.  2 A  and the open state in  FIG.  3 A . The first curved portion  230   b  may be formed to correspond to a curved surface formed on one surface of the display support structure  220 . In the embodiment, the second curved portion  230   c  may be defined by a portion of the second area   that corresponds to a curved surface of the pulley. The first curved portion  230   b  may be positioned opposite to the second curved portion  230   c  in the closed state or the open state of the electronic device  200  and improve an aesthetic appearance of the screen  230   d . According to any embodiment, the planar portion  230   a  may be disposed to be expanded while substituting for the first curved portion  230   b.    
     According to the embodiment, the flexible display  230  may further include a touch detection circuit (e.g., a touch sensor). According to various embodiments (not illustrated), the flexible display  230  may be coupled to or disposed adjacent to a pressure sensor configured to measure intensity (pressure) of touch and/or a digitizer configured to detect a stylus pen that operates in a magnetic field manner. 
     According to the embodiment, the electronic device  200  may include a microphone hole  251  (e.g., the input module  150  in  FIG.  1   ), a speaker hole  252  (e.g., the sound output module  155  in  FIG.  1   ), a connector hole  253  (e.g., the connection terminal  178  in  FIG.  1   ), a camera module  254  (e.g., the camera module  180  in  FIG.  1   ), or a flash  255 . According to various embodiments, the flash  255  may be included in the camera module  254 . In any embodiment, the electronic device  200  may exclude at least one of the constituent elements or further include other constituent elements. 
     For example, the microphone hole  251  may be formed in the second side surface  210 D and correspond to a microphone (not illustrated) positioned in the electronic device  200 . A position of the microphone hole  251  may be variously configured without being limited to the embodiment in  FIG.  2 A . According to any embodiment, the electronic device  200  may include a plurality of microphones capable of detecting a direction of sound. 
     For example, the speaker hole  252  may be formed in the second side surface  210 D and correspond to a speaker positioned in the electronic device  200 . A position of the speaker hole  252  may be variously configured without being limited to the embodiment in  FIG.  2 A . According to various embodiments, the electronic device  200  may include a telephone receiver hole. In any embodiment, the microphone hole  251  and the speaker hole  252  may be implemented as a single hole. Alternatively, the speaker hole  252  may be eliminated like a piezoelectric speaker. 
     For example, the connector hole  253  may be formed in the second side surface  210 D and corresponds to a connector (e.g., a USB connector) positioned in the electronic device  200 . The electronic device  200  may transmit and/or receive electric power and/or data to and/or an external electronic device electrically to the connector through the connector hole  253 . A position of the connector hole  253  may be variously configured without being limited to the embodiment in  FIG.  2 A . 
     For example, the camera module  254  and the flash  255  may be positioned on the rear surface  210 B of the electronic device  200 . The camera module  254  may include one lens or a plurality of lenses, an image sensor, and/or an image processor. For example, the flash  255  may include a light-emitting diode or a xenon lamp. In various embodiments, the electronic device  200  may include a plurality of camera modules without being limited to the embodiment in  FIG.  2 B or  3 B . The camera module  254  may be one of the plurality of camera modules. For example, the electronic device  200  may include a plurality of camera modules (e.g., a dual camera or a triple camera) having different attributes (e.g., angles of view) or different functions. For example, the electronic device may include a plurality of camera modules (e.g., the camera module  254 ) including lenses having different angles of view. The electronic device  200  may perform control to change the camera module that operates in the electronic device  200  based on the user&#39;s selection. As another example, the plurality of camera modules may include at least one of a wide-angle camera, a telephoto camera, a color camera, a monochrome camera, and an infrared (IR) camera (e.g., a time of flight (TOF) camera or a structured light camera). According to the embodiment, the IR camera may operate as at least a part of the sensor module (not illustrated) (e.g., the sensor module  176  in  FIG.  1   ). 
     According to various embodiments (not illustrated), the electronic device  200  may further include a camera module (e.g., a front camera) configured to produce an image signal based on light received through one surface (e.g., front surface  210 A) of the electronic device  200  placed in a direction toward the screen  230   d . For example, the camera module  254  is not limited to the embodiment in  FIG.  2 B or  3 B . The camera module  254  may be aligned with an opening (e.g., a through-hole or a notch) formed in the flexible display  230 , and the camera module  254  may be positioned in the housing  210 . The camera module  254  may produce an image signal by receiving light through the opening and a partial area of a transparent cover that overlaps the opening. For example, the transparent cover may be made of a material such as polyimide or ultra-thin glass (UTG) and protect the flexible display  230  from the outside. 
     According to various embodiments, the camera module  254  may be disposed at a lower end of at least a part of the screen  230   d  of the flexible display  230  without being limited to the embodiment in  FIG.  2 B or  3 B . In this case, it is possible to perform relevant functions (e.g., image capturing) by using the camera module  254  without visually distinguishing (or exposing) the position of the camera module  254 . For example, the camera module  254  is disposed to overlap at least a part of the screen  230   d  when viewed from above the screen  230   d  (e.g., when viewed in a −z-axis direction), such that the camera module  254  may acquire an image of an external subject without being exposed to the outside. 
     According to various embodiments (not illustrated), the electronic device  200  may further include a key input device (e.g., the input module  150  in  FIG.  1   ) (not illustrated). For example, the key input device may be positioned on the first side surface  210 C of the electronic device  200  defined by the first side cover  213 . In any embodiment (not illustrated), the key input device may include at least one sensor module. 
     According to various embodiments (not illustrated), the electronic device  200  may include various sensor modules (e.g., the sensor module  176  in  FIG.  1   ).

According to the embodiment, at least some of the first conductors  213   a  and  213   b  of the first side cover  213  may be used as an antenna radiator. According to various embodiments, the number, position, or shape of the first conductor included in the first side cover  213  or the number, position, or shape of the insulator between the first conductors may be variously configured without being limited to the embodiment in  FIG.  2 A,  2 B,  3 A , or  3 B. 
     According to the embodiment, the second side cover  214  may include two second conductors  214   a  and  214   b  or a second insulator  214   c .

     According to the embodiment, at least a part of the display support structure  220  may include an electrically conductive material and be used as an antenna radiator. For example, a part  221  (see  FIG.  3 A or  3 B ) of the display support structure  220 , which defines the third rim portion  2201 , may be used as at least one antenna radiator. The at least one antenna radiator, which is implemented by using the part  221  of the display support structure  220  including the third rim portion  2201 , may overcome a constraint on antenna design caused by the structure for implementing the sliding operation. At least one antenna radiator, which is implemented by using the part  221  of the display support structure  220  including the third rim portion  2201 , is positioned at an outer periphery of the electronic device  200 , together with the first side cover  213  and the second side cover  214 , in the open state in  FIG.  3 A  as well as the closed state in  FIG.  2 A , and this may be advantageous in ensuring the antenna radiation performance.

A repeated description of some of the reference numerals in  FIG.  4    will be omitted. 
     According to the embodiment, the support member assembly (or a support structure)  400  is a frame structure capable of withstanding a load and may contribute to durability or rigidity of the electronic device  200 . The support member assembly  400  may include a nonmetallic material (e.g., polymer) or a metallic material. The housing  210  (see  FIG.  2 A ) including the back cover  212 , the first side cover  213 , or the second side cover  214 , the pulley  460 , the display support structure  220 , the flexible display  230 , the support sheet  470 , the multi-bar structure  480 , or the printed circuit board  490  may be disposed on or coupled to the support member assembly  400 .

     For example, the first support member (or a first bracket)  410  may be provided in the form of a plate. The display support structure  220  may be disposed on one surface  410   a  of the first support member  410 . For example, the second support member (or a second bracket)  420  may be provided in the form of a plate that overlaps at least a part of the first support member  410  when viewed in the z direction. Alternatively, the second support member may be connected to the first support member  410  and/or the third support member  430 . The second support member  420  may be positioned between the first support member  410  and the third support member  430 . The third support member  430  may be coupled to the first support member  410  and/or the second support member  420 . The printed circuit board  490  may be disposed between the first support member  410  and the second support member  420 . The fourth support member  440  may be coupled to one side of a structure made by coupling the first support member  410 , the second support member  420 , and the third support member  430 . The fifth support member  450  may be coupled to the other side of the structure made by coupling the first support member  410 , the second support member  420 , and the third support member  430 . The fifth support member  450  may be positioned opposite to the fourth support member  440 . The first side cover  213  may be coupled to the support member assembly  400  at the side of the fourth support member  440 . The second side cover  214  may be coupled to the support member assembly  400  at the side of the fifth support member  450 . The back cover  212  may be coupled to the support member assembly  400  at the side of the third support member  430 . At least some of the first support member  410 , the second support member  420 , the third support member  430 , the fourth support member  440 , or the fifth support member  450  may include a metallic material and/or a nonmetallic material (e.g., polymer). According to various embodiments, at least two or more of the first support member  410 , the second support member  420 , the third support member  430 , the fourth support member  440 , and the fifth support member  450  may be integrated. According to any embodiment, the support member assembly  400  may be referred to as a structure that defines at least some of the first support member  410 , the second support member  420 , the third support member  430 , the fourth support member  440 , and the fifth support member  450 . According to any embodiment, at least some of the first support member  410 , the second support member  420 , the third support member  430 , the fourth support member  440 , and the fifth support member  450  of the support member assembly  400  may be omitted. 
     For example, the first support member  410  may include a first side surface (not illustrated) configured to face the fourth support member  440 , a second side surface  410   c  configured to face the fifth support member  450  and positioned opposite to the first side surface, a third side surface (not illustrated) configured to connect one end of the first side surface and one end of the second side surface  410   c , or a fourth side surface  410   d  configured to connect the other end of the first side surface and the other end of the second side surface  410   c  and positioned opposite to the third side surface. According to the embodiment, the pulley  460  may be positioned in the vicinity of the third side surface of the first support member  410 . As another example, in the case of the electronic device having the slide-out direction formed reversely, the pulley  460  may also be positioned in the vicinity of the fourth side surface  410   d  of the first support member  410 . The pulley  460  may include a cylindrical roller  461  extending in the direction (e.g., the y-axis direction) from the fifth support member  450  to the fourth support member  440 . The pulley  460  may include a first rotation shaft (not illustrated) connected to the roller  461 , and a second rotation shaft  463 . The first rotation shaft and the second rotation shaft  463  may be positioned opposite to each other with the roller  461  interposed therebetween. The first rotation shaft may be positioned between the roller  461  and the first side cover  213  and connected to the fourth support member  440 . The second rotation shaft  463  may be positioned between the roller  461  and the second side cover  214  and connected to the fifth support member  450 . The fourth support member  440  may include a first through-hole  441  into which the first rotation shaft is inserted. The fifth support member  450  may include a second through-hole  451  into which the second rotation shaft  463  is inserted. The roller  461  may rotate about the first rotation shaft disposed on the fourth support member  440  and rotate about the second rotation shaft  463  disposed on the fifth support member  450 . 
     According to the embodiment, the display support structure  220  may be disposed on the support member assembly  400  and slide on the first support member  410 . For example, a sliding structure may be provided between the first support member  410  and the display support structure  220 . The sliding structure may couple the first support member  410  and the display support structure  220  and support and guide the movement of the display support structure  220 . According to the embodiment, the sliding structure may include at least one elastic structure  401 . When the display support structure  220  is moved by a preset distance by an external force, the at least one elastic structure  401  may change the state from the closed state in  FIG.  2 A  to the open state in  FIG.  3 A  or from the open state to the closed state without an additional external force. For example, the at least one elastic structure  401  may include various elastic member such as a torsion spring. For example, the torsion spring, which is the at least one elastic structure  401 , may include one end connected to the display support structure  220 , the other end connected to the first support member  410 , and/or a spring portion between one end and the other end. When the display support structure  220  is moved by a preset distance in the first direction (e.g., the x-axis direction) of the slide-out by an external force, a position of one end is changed relative to the other end, such that the display support structure  220  may be moved in the first direction by elasticity of the spring portion without an additional external force. Therefore, the state may be changed from the closed state in  FIG.  2 A  to the open state in  FIG.  3 A . When the display support structure  220  is moved by a preset distance in the second direction opposite to the first direction by an external force, a position of one end is changed relative to the other end, such that the display support structure  220  may be moved in the second direction by elasticity of the spring portion without an additional external force. Therefore, the state may be changed from the open state in  FIG.  3 A  to the closed state in  FIG.  2 A . 
     According to various embodiments, the housing  210  may be defined to further include at least a part of the support member assembly  400 . For example, the housing  210  may include a first surface (e.g., one surface  410   a  defined by the first support member  410 ) directed in the first direction (e.g., the +z-axis direction), and a second surface (e.g., the rear surface  210 B in  FIG.  2 B ) directed in the second direction (e.g., the −z-axis direction) opposite to the first surface (e.g., the one surface  410   a ). The display support structure  220  may be disposed on the first surface (e.g., one surface  410   a  defined by the first support member  410 ) of the housing  210  and be slidable in a third direction (e.g., the x-axis direction) perpendicular to the first direction. 
     According to the embodiment, the flexible display  230  may include a first area   extending from the second area  . The first area   may be disposed on the display support structure  220 . When the state is changed from the closed state in  FIG.  2 A  to the open state in  FIG.  3 A , the second area   connected to the first area   comes out while being slid by the movement of the display support structure  220 , such that the screen (see the screen  230   d  in  FIG.  3 A ) may be expanded. When the state is changed from the open state in  FIG.  3 A  to the closed state in  FIG.  2 A , the second area   is at least partially retracted into the electronic device  200  by the movement of the display support structure  220 , such that the screen (see the screen  230   d  in  FIG.  2 A ) may be contracted. The support member assembly  400  may include the opening (not illustrated) through which the second area   is retracted or extended. The pulley  460  may be positioned in the opening. The opening may include one side gap between the first support member  410  and the third support member  430 . A part (e.g., the support member  431 ) of the third support member  430  disposed adjacent to the opening may have a curved shape corresponding to the curved surface of the roller  461 . The pulley  460  may be positioned to correspond to the second area  . When the state changes between the closed state in  FIG.  2 A  and the open state in  FIG.  3 A , the pulley  460  may be rotated by the movement of the second area  . 
     According to the embodiment, the support sheet  470  may be attached to a rear surface of the flexible display  230 . The rear surface of the flexible display  230  may refer to a surface positioned opposite to a surface through which light is emitted from the display panel including a plurality of pixels. The support sheet  470  may contribute to durability of the flexible display  230 . The support sheet  470  may reduce an influence of a load or stress that may occur due to the change in state between the closed state in  FIG.  2 A  and the open state in  FIG.  3 A  and affect the flexible display  230 . The support sheet  470  may prevent the flexible display  230  from being damaged by a force transmitted when the display support structure  220  moves. Although not illustrated, the flexible display  230  may include a first layer including a plurality of pixels, and a second layer coupled to the first layer. For example, the first layer may include a light-emitting layer including a plurality of pixels implemented by light-emitting elements such as organic light-emitting diodes (OLEDs) or micro light-emitting diodes (LED), and various other layers (e.g., optical layers, such as polarizing layers, for improving image quality or outdoor visibility of the screen). According to the embodiment, a plurality of pixels may not be disposed in a partial area of the flexible display  230  that at least partially overlaps at least one electronic component (e.g., the camera module or the sensor module) included in the electronic device  200  when viewed from above the screen  230   d  (see  FIG.  2 A or  3 A ) (e.g., when viewed in the −z-axis direction). According to any embodiment, a partial area of the flexible display  230 , which at least partially overlaps at least one electronic component (e.g., the camera module or the sensor module) included in the electronic device  200  when viewed from above the screen  230   d , may include a wiring structure and/or a pixel structure different from that in the other areas. For example, a partial area of the flexible display  230 , which at least partially overlaps the at least one electronic component (e.g., the camera module or the sensor module), may have a pixel density different from that of the other areas. For example, a partial area of the flexible display  230 , which at least partially overlaps the at least one electronic component (e.g., the camera module or the sensor module), may be implemented as a substantially transparent area defined by a change in pixel structure and/or wiring structure even without the opening. The second layer may include various layers that serve to support and protect the first layer (e.g., serve as buffer members (cushions)), block light, absorb or block electromagnetic waves, or diffuse, disperse, or dissipate heat. According to the embodiment, at least a part of the second layer may be configured as a conductive member (e.g., metal plate) and assist in reinforcing the rigidity of the electronic device  200 . The at least a part of the second layer may be used to block peripheral noise and disperse heat discharged from a peripheral heat dissipation component (e.g., a display drive circuit). According to the embodiment, the conductive member may include at least one of copper (Cu), aluminum (Al), SUS (stainless steel), and CLAD (e.g., a stack member in which SUS and Al are alternately disposed). 
     The support sheet  470  may at least partially cover the second layer of the flexible display  230  and be attached to the rear surface of the second layer. The support sheet  470  may be made of various metallic materials and/or nonmetallic materials (e.g., polymers). According to the embodiment, the support sheet  470  may include stainless steel. According to any embodiment, the support sheet  470  may include engineering plastic. According to any embodiment, the support sheet  470  may be integrated with the flexible display  230 . According to the embodiment, the support sheet  470  may include a first part (not illustrated) disposed along the first area   of the flexible display  230 , and a second part (not illustrated) extending from the first part and disposed along the second area  of the flexible display  230 . The second part may include a lattice structure including a plurality of openings. For example, the plurality of openings may be periodically formed and have substantially the same shape, and the plurality of openings may be arranged repeatedly at predetermined intervals. The support sheet  470  may provide elasticity (or elastic restoring force) that restores the second area   of the flexible display  230  to an unfolded state. However, the lattice structure of the second part may contribute to bendability of the second area   of the flexible display  230 . 
     According to the embodiment, the multi-bar structure  480  may be connected to the display support structure  220  and include a third surface  481  configured to face the support sheet  470 , and a fourth surface  482  positioned opposite to the third surface  481 . When the display support structure  220  moves, the multi-bar structure  480  generates friction with the fourth surface  482 , such that the movement and direction of the multi-bar structure  480  may be guided by the rotating roller  461 . According to the embodiment, the fourth surface  482  may include a plurality of bars (not illustrated) arranged and extending in a direction (e.g., the y-axis direction) directed toward the first rotation shaft (not illustrated) from the second rotation shaft  463  of the pulley  460 . The multi-bar structure  480  may be curved at portions between the plurality of bars. In various embodiments, the multi-bar structure  480  may be referred to as another term such as a ‘flexible track’ or ‘hinge rail’. 
     According to the embodiment, in the closed state in  FIG.  2 A  or the open state in  FIG.  3 A , at least a part of the multi-bar structure  480  may be positioned to overlap the screen  230   d  and support the second area   so that the second area   of the flexible display  230  is kept smoothly connected to the first area   of the flexible display  230  without being separated. The multi-bar structure  480  may contribute to the configuration in which the second area   is movable while being kept smoothly connected to the first area   without being separated when the state is changed between the closed state in  FIG.  2 A  and the open state in  FIG.  3 A . 
     The separation, which occurs due to the elasticity of the flexible display  230  and/or the support sheet  470  in the state in which the screen is expanded (e.g., the open state in  FIG.  3 A ), may cause a non-smooth screen. To prevent the non-smooth screen, a tension structure (not illustrated) may be provided for the flexible display  230  and/or the support sheet  470 . The tension structure may contribute to a smooth sliding motion while maintaining tension. 
     According to the embodiment, a processor (e.g., the processor  120  in  FIG.  1   ), a memory (e.g., the memory  130  in  FIG.  1   ), and/or an interface (e.g., the interface  177  in  FIG.  1   ) may be mounted on the printed circuit board  490 . For example, the processor may include one or more of a central processing unit, an application processor, a graphic processing device, an image signal processor, a sensor hub processor, and a communication processor. For example, the memory may include a volatile memory or a non-volatile memory. For example, the interface may include a high-definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, and/or an audio interface. For example, the interface may electrically or physically connect the electronic device  200  to an external electronic device and include a USB connector, an SD card/MMC connector, or an audio connector. The electronic device  200  may be disposed on the printed circuit board  490  or include various other elements electrically connected to the printed circuit board  490 . For example, the electronic device  200  may include a battery (not illustrated) positioned between the first support member  410  and the second support member  420  or between the second support member  420  and the back cover  212 . The battery refers to a device for supplying electric power to at least one constituent element of the electronic device  200 . For example, the battery may include a primary battery, which cannot be recharged, a rechargeable secondary battery, or a fuel cell. The battery may be integrally disposed in the electronic device  200  or disposed to be detachable from the electronic device  200 . According to various embodiments, the electronic device  200  may include an antenna (not illustrated) positioned between the first support member  410  and the second support member  420  or between the second support member  420  and the back cover  212 . For example, the antenna may include a near-field communication (NFC) antenna, a wireless charging antenna, and/or a magnetic secure transmission (MST) antenna. For example, the antenna may perform near-field communication with an external device or transmit or receive electric power required for charging in a wireless manner. In another embodiment, the antenna structure may be defined by a part of the first side cover  213  and/or a part of the second side cover  214  or a combination thereof. 
     According to the embodiment, the electronic device  200  may include a flexible printed circuit board (FPCB)  237  configured to electrically connect the flexible display  230  and the printed circuit board  490 . For example, the flexible printed circuit board  237  may be electrically connected to the printed circuit board  490  through the opening (not illustrated) formed in the display support structure  220  and the opening (not illustrated) formed in the first support member  410 .

For example, the designated frequency band may include at least one of low band (LB) (i.e., about 600 MHz to about 1 GHz), middle band (MB) (i.e., about 1 GHz to about 2.3 GHz), high band (HB) (i.e., about 2.3 GHz to about 2.7 GHz), and ultra-high band (UHB) (i.e., about 2.7 GHz to about 6 GHz). According to various embodiments, the designated frequency band may include various other frequency bands. 
       FIG.  6    is a graph illustrating antenna radiation performance related to the first antenna radiator {circle around ( 1 )}, the second antenna radiator {circle around ( 2 )}, and the third antenna radiator {circle around ( 3 )} in  FIG.  5    according to an embodiment of the disclosure. 
     Referring to  FIG.  6   , in the embodiment, reference numeral ‘ 601 ’ indicates antenna radiation performance related to the first antenna radiator {circle around ( 1 )}. Reference numeral ‘ 602 ’ indicates antenna radiation performance related to the second antenna radiator {circle around ( 2 )}. Reference numeral ‘ 603 ’ indicates antenna radiation performance related to the third antenna radiator {circle around ( 3 )}. Referring to  FIGS.  5  and  6   , the wireless communication circuit  540  may transmit and/or receive an LB signal through the first antenna radiator {circle around ( 1 )}, and the related antenna radiation performance may be in an important range of a performance ensuring level. The wireless communication circuit  540  may transmit and/or receive an UHB signal (e.g., a signal of about 3.5 GHz to about 4 GHz) through the second antenna radiator {circle around ( 2 )}, and the related antenna radiation performance may be in the important range of the performance ensuring level. The wireless communication circuit  540  may transmit and/or receive a signal with an MB, HB, or GPS (global positioning system) band through the third antenna radiator {circle around ( 3 )}, and the related antenna radiation performance may be in the important range of the performance ensuring level. 
     Referring to  FIG.  5   , in the embodiment, a wireless communication circuit  540  may transmit and/or receive an LB signal through the fourth antenna radiator {circle around ( 4 )}. The wireless communication circuit  540  may transmit and/or receive an MB and/or HB signal through the fifth antenna radiator {circle around ( 5 )}.

     According to the embodiment, the wireless communication circuit  540  (e.g., the wireless communication module  192  in  FIG.  1   ) or the processor  550  (e.g., the processor  120  in  FIG.  1   ) may transmit and/or receive data through an MIMO technique by using a plurality of antenna radiators in a communication mode using the corresponding frequency band. The memory  560  (e.g., the memory  130  in  FIG.  1   ) electrically connected to the processor  550  may store instructions that allow the processor  550  to transmit or receive data through the MIMO technique by selectively using a plurality of antenna radiators, among the first antenna radiator {circle around ( 1 )}, the second antenna radiator {circle around ( 2 )}, the third antenna radiator {circle around ( 3 )}, the fourth antenna radiator {circle around ( 4 )}, the fifth antenna radiator {circle around ( 5 )}, the sixth antenna radiator {circle around ( 6 )}, the seventh antenna radiator {circle around ( 7 )}, the eighth antenna radiator {circle around ( 8 )}, the ninth antenna radiator {circle around ( 9 )}, and the tenth antenna radiator  , based on a communication mode. For example, the MIMO technique may include a ‘beam forming’ method of removing peripheral interference and improving performance by adjusting signal intensity in accordance with a base station (or a transmitter) and a user&#39;s position angle by adjusting phase information of each of the antenna radiators. For example, the MIMO technique may include a ‘diversity’ method of improving performance by providing a distance between the antenna radiators to independently generate signals between the antenna radiator. For example, the MIMO technique may include a ‘multiplexing’ method of increasing a transmission speed by making imaginary auxiliary channels between transmission/receiving antenna radiators and transmitting different data through transmitting antennas. According to the embodiment, a technique may be used in which the base station transmits different data through the transmitting antennas and the electronic device  200  identifies transmitted data by appropriately processing signals. For example, a 4×4 MIMO technique may use four antenna radiators for the base station (or the transmitter) and the electronic device  200  (or the receiver). 
     According to various embodiments, the wireless communication circuit  540  or the processor  550  may be configured to selectively use the antenna radiator in accordance with the closed state (see  FIG.  2 A ) or the open state (see  FIG.  3 A or  5   ) of the electronic device  200  in the communication mode using the corresponding frequency band. The memory  560  may store instructions that allow the processor  550  to selectively use at least one of the first antenna radiator {circle around ( 1 )}, the second antenna radiator {circle around ( 2 )}, the third antenna radiator {circle around ( 3 )}, the fourth antenna radiator {circle around ( 4 )}, the fifth antenna radiator {circle around ( 5 )}, the sixth antenna radiator {circle around ( 6 )}, the seventh antenna radiator {circle around ( 7 )}, the eighth antenna radiator {circle around ( 8 )}, the ninth antenna radiator {circle around ( 9 )}, and the tenth antenna radiator   based on the closed state or the open state of the electronic device  200 . For example, in the closed state of the electronic device  200 , the first antenna radiator {circle around ( 1 )}, the second antenna radiator {circle around ( 2 )}, the third antenna radiator {circle around ( 3 )}, the fourth antenna radiator {circle around ( 4 )}, or the fifth antenna radiator {circle around ( 5 )} may be used. For example, in the open state of the electronic device  200 , the sixth antenna radiator {circle around ( 6 )}, the seventh antenna radiator Q, or the eighth antenna radiator {circle around ( 8 )} may be used. 
     According to various embodiments, the wireless communication circuit  540  or the processor  550  may be configured to selectively use the antenna radiator based on the instructions stored in the memory  560  and based on a position at which the user grips the electronic device  200 . For example, at least one antenna radiator, which is advantageous in ensuring antenna radiation performance in the corresponding communication mode and spaced apart from a position at which the electronic device gripped by the user&#39;s hand, may be selected and operated. 
     According to various embodiments, an antenna device may further include a frequency adjustment circuit (not illustrated) connected to a transmission line between at least one antenna radiator (e.g., the first antenna radiator {circle around ( 1 )}, the second antenna radiator {circle around ( 2 )}, the third antenna radiator {circle around ( 3 )}, the fourth antenna radiator {circle around ( 4 )}, the fifth antenna radiator {circle around ( 5 )}, the sixth antenna radiator {circle around ( 6 )}, the seventh antenna radiator {circle around ( 7 )}, the eighth antenna radiator {circle around ( 8 )}, the ninth antenna radiator {circle around ( 9 )}, or the tenth antenna radiator  ) and the wireless communication circuit  540 . The frequency adjustment circuit may include an electrical element having a component such as inductance, capacitance, or conductance applied to the transmission line. For example, the frequency adjustment circuit may include various elements such as a lumped element or a passive element. According to the embodiment, the frequency adjustment circuit (e.g., matching circuit) may adjust impedance of the transmission line or impedance of the antenna radiator. Therefore, the impedance of the transmission line and the impedance of the antenna radiator may be matched (e.g., impedance matching). The impedance matching may induce a flow of an efficient signal at a particular frequency. The impedance of the antenna radiator may be related to transmission of electric power from the transmitter (e.g., the wireless communication circuit  540 ) to the antenna radiator or transmission of electric power from the antenna radiator to the receiver (e.g., the wireless communication circuit  540 ). When the impedance of the antenna radiator and the impedance of the transmission line are matched, reflection at a connection part between the transmission line and the antenna radiator may be minimized, such that maximum electric power transmission (or minimization of electric power loss) or efficient signal transmission through the antenna radiator may be possible. According to various embodiments, the frequency adjustment circuit may move a resonant frequency of at least one antenna radiator to a designated frequency or move the resonant frequency by a designated degree. 
     According to various embodiments, in the closed state (see  FIG.  2 A ) of the electronic device  200 , the frequency adjustment circuit may reduce an electromagnetic influence from another antenna radiator (e.g., the second antenna radiator {circle around ( 2 )}, the third antenna radiator {circle around ( 3 )}, or the fifth antenna radiator {circle around ( 5 )}) or various elements of the electronic device  200  by the sixth antenna radiator {circle around ( 6 )}, the seventh antenna radiator Q, or the eighth antenna radiator {circle around ( 8 )}. The frequency adjustment circuit may allow the sixth antenna radiator {circle around ( 6 )}, the seventh antenna radiator Q, or the eighth antenna radiator {circle around ( 8 )} to have designated isolation in the closed state of the electronic device  200 . Therefore, in the closed state of the electronic device  200 , the antenna radiation performance for the sixth antenna radiator {circle around ( 6 )}, the seventh antenna radiator Q, or the eighth antenna radiator {circle around ( 8 )} may be ensured at a desired level or reach the antenna radiation performance in the open state (see  FIG.  3 A or  5   ) of the electronic device  200 .

At least a part of the display support structure  220  may include a conductive member including the third rim portion  2201  and the support portion  2202 . For example, the third rim portion  2201  and the support portion  2202  may be integrated. The support portion  2202  may include a support structure for disposing the first area   of the flexible display  230 . In  FIG.  7   , the third rim portion  2201  and the support portion  2202  are schematically illustrated to understand the antenna  700 , but the third rim portion  2201  and the support portion  2202  may be implemented in a form that may protect and support the flexible display  230 . 
     For example, the screen  230   d  may be an area of the flexible display  230  that is visible to the outside. According to the embodiment, the screen  230   d  may include the first curved portion  230   b  curvedly extending from the planar portion  230   a  or the planar portion  230   a  and positioned between the planar portion  230   a  and the third rim portion  2201 .  FIG.  7    illustrates the schematically flat support portion  2202  of the display support structure  220  for structural understanding of the antenna  700 . However, the support portion  2202  may be substantially formed in a shape for disposing and supporting the first curved portion  230   b  and the planar portion  230   a  of the screen  230   d.    
     According to any embodiment, the planar portion  230   a  may be disposed to be expanded while substituting for the first curved portion  230   b , and the support portion  2202  may be formed in a shape corresponding to the planar portion  230   a.    
     According to the embodiment, the display support structure  220  may include a slot (or slit) (e.g., the opening)  710 . For example, the slot  710  may have a first width W 1  extending in the y-axis direction (e.g., the direction between the first side cover  213  and the second side cover  214  in  FIG.  5   ) and a second width W 2  extending in the x-axis direction. For example, the first width W 1  may be larger than the second width W 2 . According to the embodiment, the slot  710  may extend to an edge  220   e  positioned in the y-axis direction. According to the embodiment, the slot  710  may be formed in the support portion  2202 . However, the disclosure is not limited thereto, and the slot  710  may be formed in the third rim portion  2201  or expanded to the third rim portion  2201 . The sixth antenna radiator {circle around ( 6 )} is a part of the display support structure  220  at the periphery of the slot  710  and may form an electromagnetic field capable of transmitting and/or receiving a signal with at least one frequency in the corresponding frequency band when the radiation current is provided from the feeding unit F 1  to the display support structure  220 . The feeding unit F 1  may be a structure (e.g., a feeding structure) that allows the wireless communication circuit  540  in  FIG.  5    to provide the radiation current to the display support structure  220 . The display support structure  220  may be electrically connected to the ground G (e.g., the ground plane included in the printed circuit board  490  in  FIG.  4   ). Therefore, the sixth antenna radiator {circle around ( 6 )} may be kept electrically connected to the ground G. The slot  710  may contribute to allowing the display support structure  220  to implement the sixth antenna radiator {circle around ( 6 )} for a path through which the radiation current flows and/or a distribution of the radiation current when the radiation current is provided to the feeding unit F 1 . With the slot  710 , the display support structure  220  may include a part that operates as the sixth antenna radiator {circle around ( 6 )}, and a part (not illustrated) that is electrically connected to the ground G and operates as the antenna ground. According to the embodiment, the position or shape of the slot  710  and the position or shape of the sixth antenna radiator {circle around ( 6 )} may be variously implemented based on a frequency of a signal to be transmitted and/or received without being limited to the embodiment in  FIG.  7   .

     According to various embodiments (not illustrated), the antenna related to the eighth antenna radiator {circle around ( 8 )} in  FIG.  5    may be implemented in substantially the same way as the antenna  700  related to the sixth antenna radiator {circle around ( 6 )} according to the embodiment in  FIG.  7   . For example, the eighth antenna radiator {circle around ( 8 )} may include a slot formed in the display support structure  220 , and the slot may extend to an edge positioned in the −y-axis direction (e.g., an edge at a side of the second side cover  214  in the closed state in  FIG.  2 A ). 
       FIG.  8    illustrates a cross-sectional structure taken along line A-A′ in the electronic device in  FIG.  5    according to an embodiment of the disclosure.

The non-conductive portion  2202   b  may dispose and support the flexible display  230  between the conductive portion  2202   a  and the flexible display  230 . According to any embodiment, a conductive member may substitute for the non-conductive portion  2202   b , and the conductive member may be connected to the conductive portion  2202   a  or integrated with the conductive portion  2202   a.    
     According to the embodiment, the non-conductive member may be disposed in the slot  710  of the display support structure  220  by injection molding or the like. The non-conductive member disposed in the slot  710  may reduce deterioration in rigidity of the display support structure  220  caused by the slot  710 . According to any embodiment (not illustrated), the non-conductive portion  2202   b  may be expanded to the slot  710 .

     According to the embodiment, the base film  820  may include a flexible film made of a material such as polyimide or polyester (PET).

According to the embodiment, the composite sheet  833   a  may be a sheet by combining and processing layers or sheets having different properties. For example, the composite sheet  833   a  may include at least one of polyimide and graphite. The composite sheet  833   a  may be substituted with a single sheet including a single material (e.g., polyimide or graphite). The composite sheet  833   a  may be positioned between the buffer layer  832  and the EMI blocking conductive sheet  833   b . The lower layer  833  may include various layers for various other functions. 
     According to various embodiments (not illustrated), at least one of additional polymer layers (e.g., layers including PI, PET, or thermoplastic polyurethane (TPU)) may be further disposed on the rear surface of the display panel  810  in addition to the base film  820 . 
     According to various embodiments, at least one of the plurality of layers (e.g., the light-blocking layer  831 , the buffer layer  832 , the composite sheet  833   a , and the EMI blocking conductive sheet  833   b ) included in the lower panel  830  may be eliminated.

     According to various embodiments, at least some of the plurality of layers included in the lower layer  833  may include an opening formed to correspond to a sensor (e.g., a fingerprint sensor) positioned in the electronic device  200 . The sensor may overlap the opening or be at least partially inserted into a space of the opening. At least two or more layers may each include an opening, the openings formed in the layers may overlap one another and have substantially the same size and shape. According to any embodiment, the openings formed in the layers may not be identical in size or shape to one another. 
     According to the embodiment, the transparent cover  860  may cover the display panel  810  of the flexible display  230 . The transparent cover  860  may protect the flexible display  230  from the outside. For example, the transparent cover  860  may be implemented in the form of a thin film (e.g., a thin-film layer) that may contribute to bendability. According to the embodiment, transparent cover  860  may include a plastic film (e.g., a polyimide film) or a thin-film glass (e.g., an ultra-thin glass (UTG). The optical layer  840  may be positioned between the transparent cover  860  and the display panel  810 . 
     According to various embodiments (not illustrated), the transparent cover  860  may include a plurality of layers. For example, the transparent cover  860  may have a shape in which various coating layers are disposed on a plastic film or a thin-film glass. For example, the transparent cover  860  may have a shape in which at least one protective layer or coating layer including a polymer material (e.g., PET (polyester), PI (polyimide), or TPU (thermoplastic polyurethane)) is disposed on a plastic film or thin-film glass. 
     For example, the optical layer  840  may include a polarizing layer (a polarizing layer or polarizer), or a phase delay layer (a retardation layer or retarder). The polarizing layer and phase delay layer may improve outdoor visibility of the screen. According to the embodiment, the optical layer  840  may selectively transmit light that is generated from a light source of the display panel  810  and vibrates in a predetermined direction. According to various embodiments, the polarizing layer and the phase delay layer may be combined to provide a single layer, and this layer may be defined as a ‘circularly polarized light layer’. The optical transparent bonding member  850  may be positioned between the transparent cover  860  and the optical layer  840 , and, for example, include optical clear adhesive (OCA), optical clear resin (OCR), or super view resin (SVR). According to various embodiments, the polarizing layer (or the circularly polarized light layer) may be eliminated.

     According to various embodiments (not illustrated), the flexible display  230  may include a touch detection circuit (e.g., a touch sensor). The touch detection circuit may be implemented as a transparent conductive layer (or film) based on various electrically conductive materials such as indium tin oxide (ITO). According to the embodiment, the touch detection circuit may be disposed between the transparent cover  860  and the optical layer  840  (e.g., add-on type). According to another embodiment, the touch detection circuit may be disposed between the display panel  810  and the optical layer  840  (e.g., on-cell type). According to another embodiment, the display panel  810  may include a touch detection circuit or a touch detection function (e.g., in-cell type). 
     According to various embodiments (not illustrated), the display panel  810  may be based on OLEDs and include the encapsulation layer (e.g., thin-film encapsulation (TFE))  813  disposed between the light-emitting layer  811  and the optical layer  840 . For example, the encapsulation layer  813  may serve as a pixel protection layer for protecting the plurality of pixels of the light-emitting layer  811 . According to various embodiments (not illustrated), the flexible display  230  may be a touch detection circuit provided between the encapsulation layer  813  and the optical layer  840  and disposed on the encapsulation layer  813  and include a conductive pattern such as a metal mesh (e.g., an aluminum metal). For example, to correspond to the curved flexible display  230 , the metal mesh may have higher durability than the transparent conductive layer implemented by ITO. 
     According to various embodiments (not illustrated), the flexible display  230  may further include to the pressure sensor configured to measure intensity (pressure) of touch. 
     According to various embodiments (not illustrated), some of the plurality of layers included in the lower panel  830  may include a digitizer for detecting a pen input device (e.g., a stylus pen). For example, the digitizer may be an electromagnetic induction panel for detecting the pen input device that operates in a magnetic field method. According to various embodiments, the electromagnetic induction panel may be eliminated in accordance with a method of implementing the pen input device. For example, the electromagnetic induction panel may be eliminated in an embodiment in which the pen input device generates a signal by using electric power of a battery included in the pen input device. 
     According to various embodiments, the display panel  810 , or the plurality of layers included in the lower panel  830 , the layered structure thereof, or the stacking order may be variously implemented. According to various embodiments, the flexible display  230  may be implemented by eliminating some of the constituent elements or adding other constituent elements in accordance with the tendency of the provided form or convergence. 
     According to the embodiment, the wireless communication circuit  540  in  FIG.  5    may be electrically connected to the sixth antenna radiator {circle around ( 6 )} through an electrical path  870  such as an FPCB or cable. For example, the electrical path  870  may be disposed on the display support structure  220  or in the display support structure  220 . 
     Referring to  FIGS.  7  and  8   , in the embodiment, the first area   of the flexible display  230  may be disposed on the support structure  220  to reduce an influence applied to the antenna radiation performance of the sixth antenna radiator {circle around ( 6 )}. For example, the EMI blocking conductive sheet  833   b  may be disposed to be spaced apart from the sixth antenna radiator {circle around ( 6 )} at a level at which the antenna radiation performance of the sixth antenna radiator {circle around ( 6 )} may be ensured. For example, the EMI blocking conductive sheet  833   b  may be disposed so as not to substantially overlap the sixth antenna radiator {circle around ( 6 )} when viewed from above the planar portion  230   a . Therefore, the EMI blocking conductive sheet  833   b  may reduce an electromagnetic influence (e.g., deterioration in antenna radiation performance) applied to the sixth antenna radiator {circle around ( 6 )}. 
     According to various embodiments, the support sheet  470  may include a metallic material and be disposed to be spaced apart from the sixth antenna radiator {circle around ( 6 )} at a level at which the antenna radiation performance may be ensured. According to various embodiments, the support sheet  470  may be disposed so as not to substantially overlap the sixth antenna radiator {circle around ( 6 )} when viewed from above the planar portion  230   a . Therefore, the support sheet  470  may reduce an electromagnetic influence (e.g., deterioration in antenna radiation performance) applied to the sixth antenna radiator {circle around ( 6 )}. According to any embodiment, the support sheet  470  may be eliminated from the first area   of the flexible display  230 . 
       FIG.  9    is a graph illustrating a ratio of an output voltage to an input voltage in a frequency distribution according to a first width W 1  of a slot of the antenna in  FIG.  7    according to an embodiment of the disclosure. 
     Referring to  FIGS.  7  and  9   , for example, a physical length of the sixth antenna radiator {circle around ( 6 )} and an electrical length (electrical path) thereof (e.g., a length expressed as a ratio of a wavelength) may vary depending on the first width W 1  of the slot  710 . According to the embodiment, as the first width W 1  of the slot  710  increases, the resonant frequency corresponding to the electrical length may move to a low frequency. According to the embodiment, according to the embodiment in  FIG.  7   , the sixth antenna radiator {circle around ( 6 )}, which operates in IFA based on the slot  710 , may have an electrical length of about λ/4. The physical length of the sixth antenna radiator {circle around ( 6 )} and the electrical length thereof may also vary depending on the second width W 2  of the slot  710 . The shape of the slot  710  (e.g., the first width W 1  or the second width W 2 ) may be variously implemented to implement the sixth antenna radiator {circle around ( 6 )} and the electrical length thereof for forming an electromagnetic field for transmitting and/or receiving at least one signal of a preset or designated frequency band. 
       FIG.  10    schematically illustrates an antenna according to an embodiment of the disclosure.  FIG.  11    is a graph illustrating antenna radiation performance related to the antenna in  FIG.  10    according to an embodiment of the disclosure. 
     Referring to  FIG.  10   , in the embodiment, an antenna  1000  may include the sixth antenna radiator {circle around ( 6 )} defined by a part of a display support structure  1020 , and a feeding unit F 2  and a ground G electrically connected to the sixth antenna radiator {circle around ( 6 )}. The sixth antenna radiator {circle around ( 6 )} may include a part of the display support structure  1020  at the periphery of a slot  1022  (e.g., the slot  710  in  FIG.  7   ) formed in the display support structure  1020 . Although not illustrated, a non-conductive member may be disposed in the slot  1022  by injection molding or the like.  FIG.  10    illustrates an embodiment in which a planar portion  1030   a  is expanded while substituting for the first curved portion  230   b  in  FIG.  7   . Therefore, a support portion (e.g., the support portion  2202  in  FIG.  7   ) of the display support structure  1020  may be formed to be flat while corresponding to the planar portion  1030   a.    
     According to the embodiment, reference numeral ‘ 1001 ’ indicates a first case in which the planar portion  1030   a  of a flexible display  1030  does not overlap the slot  1022  of the display support structure  1020  when viewed from above the planar portion  1030   a . Reference numeral ‘ 1002 ’ indicates a second case in which the planar portion  1030   a  of the flexible display  1030  at least partially overlaps the slot  1022  of the display support structure  1020  when viewed from above the planar portion  1030   a . Reference numeral ‘ 1003 ’ indicates a third case in which the planar portion  1030   a  of the flexible display  1030  overlaps the entire slot  1022  of the display support structure  1020  when viewed from above the planar portion  1030   a . In the embodiment, the planar portion  1030   a  may be a part including a lower panel (e.g., the lower panel  802  in  FIG.  8   ). For example, the lower panel  830  may include a blocking conductive sheet (e.g., the blocking conductive sheet  833   b  in  FIG.  8   ). 
     Referring to  FIG.  11   , reference numeral ‘ 1101 ’ indicates antenna radiation performance related to the first case or a case in which the flexible display  1030  does not overlap the antenna  1000 . Reference numeral ‘ 1102 ’ indicates antenna radiation performance related to the second case. Reference numeral ‘ 1103 ’ indicates antenna radiation performance related to the third case. With reference to the comparison between the graphs indicated by reference numerals ‘ 1101 ,’ ‘ 1102 ,’ and ‘ 1103 ’, the antenna radiation performance deteriorates by about 2 dB in the second case in comparison with the first case, for example, but the second case have efficiency of about −6 dB or more that is an antenna performance ensuring level. For example, in the third case, it may be difficult to ensure the antenna performance in comparison with the first case or the second case. As a degree to which the planar portion  1030   a  of the flexible display  1030  overlaps the slot  1022  of the display support structure  1020  increases, it is more difficult to ensure the antenna radiation performance. For example, as a degree to which the planar portion  1030   a  of the flexible display  1030  overlaps the slot  1022  of the display support structure  1020  increases, a degree to which a conductive material (e.g., the EMI blocking conductive sheet  833   b  in  FIG.  8   ) included in the flexible display  1030  overlaps the slot  1022  may increase, and a spacing distance between the conductive material and the sixth antenna radiator {circle around ( 6 )} may decrease. Therefore, as the degree to which the planar portion  1030   a  of the flexible display  1030  overlaps the slot  1022  of the display support structure  1020  increases, an influence applied to the sixth antenna radiator {circle around ( 6 )} by the conductive material included in the flexible display  1030  may increase. 
     According to the embodiment, in comparison with the embodiment in  FIG.  10   , the embodiment in  FIG.  7  or  8    may be more advantageous in increasing, by the first curved portion  230   b , a distance from the sixth antenna radiator {circle around ( 6 )} while decreasing the degree to which the conductive material (e.g., the EMI blocking conductive sheet  833   b  in  FIG.  8   ) included in the flexible display  230  overlaps the slot  710 . 
     According to any embodiment, in the second case (see reference numeral ‘ 1002 ’) or the third case (see reference numeral ‘ 1003 ’), the EMI blocking conductive sheet included in the flexible display  1030  may be implemented to include an opening that at least partially overlaps the sixth antenna radiator {circle around ( 6 )} when viewed from above the planar portion  1030   a . The opening of the EMI blocking conductive sheet may have a shape (e.g., size) to reduce an electromagnetic influence applied to the sixth antenna radiator {circle around ( 6 )} at a level at which the EMI blocking performance may be ensured. 
       FIG.  12    schematically illustrates an antenna according to an embodiment of the disclosure. 
     Referring to  FIG.  12   , in the embodiment, an antenna  1200  may include the sixth antenna radiator {circle around ( 6 )} defined by a part of the display support structure  220 , and a feeding unit F 3  and a ground G electrically connected to the sixth antenna radiator {circle around ( 6 )}. According to the embodiment, the sixth antenna radiator {circle around ( 6 )} may include at least a part of the display support structure  220  that surrounds a slot  1210  (e.g., the slot  710  in  FIG.  7   ) formed in the display support structure  220 . A repeated description of some of the reference numerals in  FIG.  12    will be omitted. 
     According to the embodiment, for example, a feeding point  1201  of the sixth antenna radiator {circle around ( 6 )} electrically connected to the feeding unit F 3  and a grounding point  1202  of the sixth antenna radiator {circle around ( 6 )} electrically connected to the ground G may be positioned opposite to the third rim portion  2201  with the slot  1210  interposed therebetween. The antenna  1200  may include an electrical path  1204  that electrically connects one position (e.g., the feeding point  1201 ) and another position  1203  of the sixth antenna radiator {circle around ( 6 )} while traversing the slot  1210 . The antenna  1200  may radiate radio waves by supplying power to the sixth antenna radiator {circle around ( 6 )} of the display support structure  220 . A part of the display support structure  220  including the slot  1210  may serve as the sixth antenna radiator {circle around ( 6 )} by a potential difference between the feeding point (feeding point)  1201  of the sixth antenna radiator {circle around ( 6 )}, which is electrically connected to the feeding unit F 3  and is a point having the maximum radiation current, and the grounding point (grounding point)  1202  of the sixth antenna radiator {circle around ( 6 )} electrically connected to the ground G. According to the embodiment, the sixth antenna radiator {circle around ( 6 )} may operate as an IFA (inverted F antenna). The positions or number of the feeding point  1201  or the grounding point  1202  may be variously implemented without being limited to the embodiment in  FIG.  12   . 
       FIG.  13 A  schematically illustrates an antenna according to an embodiment of the disclosure. 
     Referring to  FIG.  13 A , in the embodiment, an antenna  1300  may include the sixth antenna radiator {circle around ( 6 )} defined by a part of the display support structure  220 , and a feeding unit F 4  and a ground G electrically connected to the sixth antenna radiator {circle around ( 6 )}. A repeated description of some of the reference numerals in  FIG.  13 A  will be omitted. 
     In comparison with the slot  1210  according to the embodiment in  FIG.  12   , a slot  1310  formed in the display support structure  220  according to the embodiment may have a shape in which the entire slot  1310  is surrounded by the display support structure  220 . The sixth antenna radiator {circle around ( 6 )} may include at least a part of the display support structure  220  that surrounds the slot  1310  of the display support structure  220 . According to the embodiment, a feeding point  1301  of the sixth antenna radiator {circle around ( 6 )} electrically connected to the feeding unit F 4  and a grounding point  1302  of the sixth antenna radiator {circle around ( 6 )} electrically connected to the ground G may be positioned opposite to each other with the slot  1310  interposed therebetween. The antenna  1300  may radiate radio waves by supplying power to the sixth antenna radiator {circle around ( 6 )} of the display support structure  220 . A part of the display support structure  220  including the slot  1310  may serve as the sixth antenna radiator {circle around ( 6 )} by a potential difference between the feeding point (feeding point)  1301  of the sixth antenna radiator {circle around ( 6 )}, which is electrically connected to the feeding unit F 4  and is a point having the maximum radiation current, and the grounding point (grounding point)  1302  of the sixth antenna radiator {circle around ( 6 )} electrically connected to the ground G. According to the embodiment, the sixth antenna radiator {circle around ( 6 )} may operate as a slot antenna or a slit antenna. 
     Referring to  FIGS.  12  and  13 A , in the embodiment, an electrical length (e.g., a length expressed as a ratio of a wavelength) of the slot  1210  or  1310  may substantially affect frequency characteristics of the antenna  1200  or  1300 . According to the embodiment, the sixth antenna radiator {circle around ( 6 )} in  FIG.  12   , which operates in IFA based on the slot  1210 , may have an electrical length of about λ/4. According to the embodiment, the sixth antenna radiator {circle around ( 6 )} in  FIG.  13 A , which operates as a slot antenna based on the slot  1310 , may have an electrical length of about λ/2. 
       FIG.  13 B  is a graph illustrating a ratio of an output voltage to an input voltage in a frequency distribution according to a width W 3  by which the slot extends in the y-axis direction in the antenna in  FIG.  13 A  according to an embodiment of the disclosure. 
     Referring to  FIGS.  13 A and  13 B , for example, a physical length of the sixth antenna radiator {circle around ( 6 )} and an electrical length thereof may vary depending on the width W 3  of the slot  1310 . According to the embodiment, as the width W 3  of the slot  1310  increases, the resonant frequency corresponding to the electrical length may move to a low frequency. According to various embodiments, although not illustrated, the physical size of the sixth antenna radiator {circle around ( 6 )} and the electrical length thereof may also vary depending on a width of the slot  1310  extending in another direction (e.g., the x-axis direction). According to the embodiment, the shape of the slot  1310  may be variously implemented to implement the sixth antenna radiator {circle around ( 6 )} and the electrical length thereof for forming an electromagnetic field for transmitting and/or receiving a signal of a preset or designated frequency band. 
     Referring to  FIGS.  12  and  13 A , in various embodiments, the flexible display  230  (see  FIG.  7  or  10   ) may be disposed on the support structure  220  to reduce an influence applied to the antenna radiation performance of the sixth antenna radiator {circle around ( 6 )}. For example, the EMI blocking conductive sheet (e.g., the EMI blocking conductive sheet  833   b  in  FIG.  8   ) included in the flexible display  230  may be disposed to be spaced apart from the sixth antenna radiator {circle around ( 6 )} at a level at which the antenna radiation performance of the sixth antenna radiator {circle around ( 6 )} may be ensured. For example, the EMI blocking conductive sheet  833   b  included in the flexible display  230  may be disposed so as not to substantially overlap the slot  1210  or  1310  of the display support structure  220  or the sixth antenna radiator {circle around ( 6 )} to ensure the antenna radiation performance when viewed in the −z direction. As another example, the EMI blocking conductive sheet included in the flexible display  230  may be implemented to include an opening that at least partially overlaps the slot  1210  or  1310  of the display support structure  220  when viewed in the −z direction. In the embodiment, the opening of the EMI blocking conductive sheet may have a shape (e.g., size) to reduce an electromagnetic influence applied to the sixth antenna radiator {circle around ( 6 )} at a level at which the EMI blocking performance may be ensured. 
     According to various embodiments, the support sheet  470  in  FIG.  4    may include a metallic material and extend between the display support structure  220  and the flexible display  230  (see  FIGS.  7  and  10   ). The support sheet  470  may be implemented to reduce an electromagnetic influence applied to the sixth antenna radiator {circle around ( 6 )} in substantially the same way as the EMI blocking conductive sheet. 
       FIG.  14 A  schematically illustrates an antenna related to the seventh antenna radiator {circle around ( 7 )} in the electronic device in  FIG.  5    according to an embodiment of the disclosure. 
     Referring to  FIG.  14 A , in the embodiment, an antenna  1400  may include the seventh antenna radiator {circle around ( 7 )} defined by a part of the display support structure  220 , and a feeding unit F 5  and a ground G electrically connected to the seventh antenna radiator {circle around ( 7 )}. The display support structure  220  may include the third rim portion  2201  (see  FIG.  2 A or  3 A ), and a support portion  2202  extending from the third rim portion  2201  and facing the first area   of the flexible display  230  (see  FIG.  7   ). In  FIG.  14 A , the third rim portion  2201  and the support portion  2202  are schematically illustrated to understand the antenna  1400 , but the third rim portion  2201  and the support portion  2202  may be implemented in a form that may protect and support the flexible display  230 . A repeated description of some of the reference numerals in  FIG.  14 A  will be omitted. 
     According to the embodiment, the display support structure  220  may include another slot  1411  formed in the third rim portion  2201 . A slot  1410  formed in the display support structure  220  may be connected to the other slot  1411 . According to various embodiments, a non-conductive member (not illustrated) may be disposed on the slot  1410  and/or the other slot  1411 . For example, a part of the non-conductive member may be disposed in the other slot  1411  and define a part of the outer surface of the electronic device  200  (see  FIG.  2 A ). The seventh antenna radiator {circle around ( 7 )} is a part of the display support structure  220  at the periphery of the slot  1410  and the other slot  1411  and may form an electromagnetic field capable of transmitting and/or receiving a signal with at least one frequency when the radiation current is provided from the feeding unit F 5  to the display support structure  220 . The display support structure  220  may be electrically connected to the ground G (e.g., the ground plane included in the printed circuit board  490  in  FIG.  4   ). Therefore, the seventh antenna radiator {circle around ( 7 )} may be kept electrically connected to the ground G. The slot  1410  may contribute to allowing the display support structure  220  to implement the seventh antenna radiator {circle around ( 7 )} for a path through which the radiation current flows and/or a distribution of the radiation current when the radiation current is provided to the feeding unit F 5 . With the slot  1410 , the display support structure  220  may include a part that operates as the seventh antenna radiator {circle around ( 7 )}, and a part (not illustrated) that is electrically connected to the ground G and operates as the antenna ground. According to the embodiment, the seventh antenna radiator {circle around ( 7 )} may operate as an IFA (inverted F antenna). The position or shape of the slot  1410  and the position or shape of the seventh antenna radiator {circle around ( 7 )} may be variously implemented based on a frequency of a signal to be transmitted and/or received without being limited to the embodiment in  FIG.  14 A . According to various embodiments (not illustrated), like the embodiment in  FIG.  12     13 A, or  13 B, the antenna  1400  may be implemented to include the ground G, a feeding unit F 5 , or the seventh antenna radiator {circle around ( 7 )} that operates as a loop antenna, a slit antenna, a slot antenna, or an open slot antenna. 
       FIG.  14 B  is a graph illustrating a ratio of an output voltage to an input voltage in a frequency distribution according to a width W 4  by which a portion formed on a support portion (e.g., support portion  2202 ) in a slot (e.g., slot  1410 ) extends in the y-axis direction in the antenna illustrated in  FIG.  14 A  according to an embodiment of the disclosure. 
     Referring to  FIGS.  14 A and  14 B , for example, a physical size of the seventh antenna radiator {circle around ( 7 )} and an electrical length thereof may vary depending on the width W 4  of the slot  1410 . According to the embodiment, as the width W 4  of the slot  1410  increases, the resonant frequency corresponding to the electrical length may move to a low frequency. For example, when the width W 4  of the slot  1410  is about 25 mm, the antenna  1400  may resonate at about 2.3 GHz. When the width W 4  is larger than 25 mm, the antenna may resonate at a frequency smaller than about 2.3 GHz. According to various embodiments, although not illustrated, the physical size of the seventh antenna radiator {circle around ( 7 )} and the electrical length thereof may vary depending on a width of the slot  1410  in another direction (e.g., the x-axis direction). The shape of the slot  1410  may be variously implemented to implement the seventh antenna radiator {circle around ( 7 )} and the electrical length thereof for forming an electromagnetic field for transmitting and/or receiving a signal of a preset or designated frequency band. According to the embodiment, the antenna  1400  may be implemented to transmit and/or receive at least one signal in a band with a frequency of about 600 MHz to about 6 GHz. 
       FIG.  15    schematically illustrates an antenna related to a sixth antenna radiator {circle around ( 6 )} in the electronic device in  FIG.  5    according to an embodiment of the disclosure. 
     Referring to  FIG.  15   , in the embodiment, an antenna  1500  may include the sixth antenna radiator {circle around ( 6 )} defined by a part of the display support structure  220 , and a feeding unit F 6 , and a ground G, or a conductive pattern  1520 . The sixth antenna radiator {circle around ( 6 )} may be implemented based on a slot  1510  (e.g., the slot  710  in  FIG.  7   ) formed in the display support structure  1020 . A repeated description of some of the reference numerals in  FIG.  15    will be omitted. 
     According to the embodiment, the conductive pattern  1520  may be disposed in the slot  1510  or positioned to at least partially overlap the slot  1510  when viewed in the z-axis direction. For example, the non-conductive member (not illustrated) may be disposed in the slot  1510  of the display support structure  220  by injection molding or the like. The conductive pattern  1520  may be disposed on the non-conductive member or in the non-conductive member. The conductive pattern  1520  may be disposed to be physically separated from the sixth antenna radiator {circle around ( 6 )}. 
     According to the embodiment, the conductive pattern  1520  may be electrically connected to the feeding unit F 6 . A part of the display support structure  220  electrically connected to the ground G may be supplied with power indirectly from the conductive pattern  1520  and operate as the sixth antenna radiator {circle around ( 6 )}. For example, the electromagnetic coupling between the conductive pattern  1520  and the sixth antenna radiator {circle around ( 6 )} may allow the antenna  1500  to form an electromagnetic field capable of transmitting and/or receiving at least one signal with in the corresponding frequency band. According to another embodiment, like reference numeral ‘ 1501 ’, the sixth antenna radiator {circle around ( 6 )} may include at least a part of the display support structure  220  that surrounds the slot  1510 . A part of the display support structure  220 , which is supplied with power indirectly from the conductive pattern  1520  and operates as the sixth antenna radiator {circle around ( 6 )}, may be variously implemented based on the slot  1510  without being limited to the embodiment in  FIG.  15   . According to various embodiments, the slot  1510  may be formed in the same way as the slot  1310  according to the embodiment in  FIG.  13 A . 
     According to various embodiments, the structure for indirectly supplying power to the sixth antenna radiator {circle around ( 6 )} according to the embodiment in  FIG.  15    may be applied to the antenna  1400  in  FIG.  14 A  related to the seventh antenna radiator {circle around ( 7 )}. 
     In various embodiments, the flexible display  230  (see  FIG.  7  or  10   ) may be disposed on the display support structure  220  to reduce an influence applied to the antenna radiation performance of the sixth antenna radiator {circle around ( 6 )}. For example, the EMI blocking conductive sheet (e.g., the EMI blocking conductive sheet  833   b  in  FIG.  8   ) included in the flexible display  230  may be disposed to be spaced apart from the sixth antenna radiator {circle around ( 6 )} at a level at which the antenna radiation performance of the sixth antenna radiator {circle around ( 6 )} may be ensured. For example, the EMI blocking conductive sheet included in the flexible display  230  may be disposed so as not to substantially overlap the slot  1510 , the conductive pattern  1520 , or the sixth antenna radiator {circle around ( 6 )} to ensure the antenna radiation performance when viewed in the −z direction. As another example, the EMI blocking conductive sheet included in the flexible display  230  may be disposed to partially overlap the slot  1510  or the conductive pattern  1520  when viewed in the −z direction at a level at which the antenna radiation performance may be ensured. As another example, the EMI blocking conductive sheet included in the flexible display  230  may be implemented to include an opening that at least partially overlaps the slot  1510  or the conductive pattern  1520  when viewed in the −z direction. The opening of the EMI blocking conductive sheet may have a shape (e.g., size) to reduce an electromagnetic influence applied to the sixth antenna radiator {circle around ( 6 )} at a level at which the EMI blocking performance may be ensured. According to various embodiments, the support sheet  470  in  FIG.  4    may include a metallic material and extend between the display support structure  220  and the flexible display  230  (see  FIGS.  7  and  10   ). The support sheet  470  may be implemented to reduce an electromagnetic influence applied to the sixth antenna radiator {circle around ( 6 )} in substantially the same way as the EMI blocking conductive sheet. 
       FIG.  16    schematically illustrates an antenna related to a sixth antenna radiator {circle around ( 6 )} in the electronic device in  FIG.  5    according to an embodiment of the disclosure. 
     Referring to  FIG.  16   , in the embodiment, an antenna  1600  may include the sixth antenna radiator {circle around ( 6 )} defined by a part of the display support structure  220 , and a feeding unit F 7 , and a ground G, or a conductive pattern  1620 . The feeding unit F 7 , the ground G, and the conductive pattern  1620  may be electrically connected to the sixth antenna radiator {circle around ( 6 )}. The sixth antenna radiator {circle around ( 6 )} may be implemented based on a slot  1610  (e.g., the slot  710  in  FIG.  7   ) formed in the display support structure  1020 . A repeated description of some of the reference numerals in  FIG.  16    will be omitted. 
     According to the embodiment, the conductive pattern  1620  may be electrically connected to the sixth antenna radiator {circle around ( 6 )}. The conductive pattern  1620  may be disposed in the slot  1610  or positioned to at least partially overlap the slot  1610  when viewed in the z-axis direction. For example, the non-conductive member (not illustrated) may be disposed in the slot  1610  of the display support structure  220  by injection molding or the like. The conductive pattern  1620  may be disposed on the non-conductive member or in the non-conductive member. The conductive pattern  1620 , together with the sixth antenna radiator {circle around ( 6 )} electrically connected to the feeding unit F 7 , may operate as an additional antenna radiator. According to various embodiments, the conductive pattern  1620  of the antenna  1600  may form at least one additional resonant frequency. 
     According to various embodiments (not illustrated), unlike the embodiment in  FIG.  15   , the feeding unit F 7  may also be electrically connected to the conductive pattern  1620 . According to the embodiment, the sixth antenna radiator {circle around ( 6 )} may include a protrusion formed toward the slot  1610 . The protrusion may be connected to the conductive pattern  1620  and electrically connected to the wireless communication circuit (e.g., the wireless communication circuit  540  in  FIG.  5   ). According to the embodiment, a feeding point at one position  1601  of the sixth antenna radiator {circle around ( 6 )} electrically connected to the feeding unit F 7  may be positioned on the conductive pattern  1620 . The antenna  1600  may include an electrical path  1604  that electrically connects one position  1601  of the conductive pattern  1620  and one position (see reference number ‘ 1603 ’) of the sixth antenna radiator {circle around ( 6 )}. According to the embodiment, for example, the one position  1603  electrically connected to the feeding unit F 7  and a ground point  1602  of the sixth antenna radiator {circle around ( 6 )} electrically connected to the ground G may be positioned opposite to the third rim portion  2201  with the slot  1610  interposed therebetween. 
     According to the embodiment, the single feeding unit F 7  may simultaneously supply power to the (or both the) conductive pattern  1620  and the sixth antenna radiator {circle around ( 6 )}, and thus two resonant frequencies may be formed. 
     According to the embodiment, the conductive pattern  1620  may be implemented as an FPCB. According to another embodiment, the display support structure  220  may be implemented to include the conductive pattern  1620 . 
     According to various embodiments, the structure including the conductive pattern  1620  according to the embodiment in  FIG.  16    may also be applied to the antenna  1400  in  FIG.  14 A  related to the seventh antenna radiator {circle around ( 7 )}. For example, the conductive pattern (e.g., the conductive pattern  1620  in  FIG.  16   ) may be disposed in the slot  1410 , and the conductive pattern may be electrically connected to the seventh antenna radiator {circle around ( 7 )}. The conductive pattern and the seventh antenna radiator {circle around ( 7 )} may be electrically connected to the wireless communication circuit at the same position. For example, the conductive pattern and the seventh antenna radiator {circle around ( 7 )} may be identical in feeding point to each other. 
     In various embodiments, the flexible display  230  (see  FIG.  7  or  10   ) may be disposed on the display support structure  220  to reduce an influence applied to the antenna radiation performance of the sixth antenna radiator {circle around ( 6 )}. For example, the EMI blocking conductive sheet (e.g., the EMI blocking conductive sheet  833   b  in  FIG.  8   ) included in the flexible display  230  may be disposed to be spaced apart from the sixth antenna radiator {circle around ( 6 )} and the conductive pattern  1620  at a level at which the antenna radiation performance of the sixth antenna radiator {circle around ( 6 )} may be ensured. For example, the EMI blocking conductive sheet included in the flexible display  230  may be disposed so as not to substantially overlap the slot  1610 , the conductive pattern  1620 , or the sixth antenna radiator {circle around ( 6 )} to ensure the antenna radiation performance when viewed in the −z direction. As another example, the EMI blocking conductive sheet included in the flexible display  230  may be disposed to partially overlap the slot  1610  or the conductive pattern  1620  when viewed in the −z direction at a level at which the antenna radiation performance may be ensured. As another example, the EMI blocking conductive sheet included in the flexible display  230  may be implemented to include an opening that at least partially overlaps the slot  1610  or the conductive pattern  1620  when viewed in the −z direction. The opening of the EMI blocking conductive sheet may have a shape (e.g., size) to reduce an electromagnetic influence applied to the sixth antenna radiator {circle around ( 6 )} and/or the conductive pattern  1620  at a level at which the EMI blocking performance may be ensured. According to various embodiments, the support sheet  470  in  FIG.  4    may include a metallic material and extend between the display support structure  220  and the flexible display  230  (see  FIGS.  7  and  10   ). The support sheet  470  may be implemented to reduce an electromagnetic influence applied to the sixth antenna radiator {circle around ( 6 )} and/or the conductive pattern  1620  in substantially the same way as the EMI blocking conductive sheet.
