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 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)).

For example, a processor(e.g., the processor  120 ) of the machine (e.g., the electronic device  101 ) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter . The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.

     According to various embodiments, the display module  230  may be a flexible display of which at least a partial region may be folded. In an embodiment, a substrate of the display module  230  may be formed of a flexible material. For example, the substrate of the display module  230  may be formed of a polymer material such as polyethylene terephthalate (PET) and polyimide (PI), or glass processed to have a very thin thickness. 
     Referring to  FIG.  2 C , in a state where the electronic device  200  is folded, the first housing  210  and the second housing  220  may substantially face each other. Thus, since the electronic device  200  may be folded to improve portability of the electronic device  200 , it is possible to more compactly manufacture the electronic device  200  including the large-area display module  230 . In addition, since a part of the display module  230  exposed to the outside is reduced in the folded state as shown in  FIG.  2 C , damage or contamination of the display module  230  can be prevented. 
     According to various embodiments, the display module  230  may include a hole  231  for transmitting external light to a camera module (e.g., the camera module  180  of  FIG.  1   ) which may be disposed on a rear surface of the display module  230 . For example, as shown in  FIG.  2 A , the hole  231  which transmits light to a camera module may be positioned at an upper end portion of the display module  230 . In an embodiment, various sensor modules (e.g., an infrared sensor and an illuminance sensor)  240  related to light may be disposed around the hall  231 . 
     According to various embodiments, the electronic device  200  may include a physical button  250  capable of generating an electrical signal by being pressed by an external force. For example, as shown in  FIGS.  2 A and  2 B , at least one physical button  250  may be disposed on a side surface of the electronic device  200 . 
     According to various embodiments, the electronic device  200  may include a microphone hole  260  and speaker holes  271  and  272 . The microphone hole  260  may include a microphone disposed therein so as to acquire external sound, and in some embodiments, multiple microphones may be disposed therein so as to detect the direction of sound. The speaker holes  271  and  272  may include an external speaker hole  272  and a phone call receiver hole  271 . In some embodiments, the speaker holes  271  and  272  and the microphone hole  260  may be implemented as a single hole, or only a speaker may be included without the speaker holes  271  and  272  (e.g., a piezo speaker). 
     According to various embodiments, the electronic device  200  may include a connection interface  280  (e.g., the interface  177  of  FIG.  1   ). The connection interface  280  may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, and/or an audio interface. In an embodiment, the connection interface  280  may electrically or physically connect the electronic device  200  to an external electronic device, and may include a USB connector, an SD card/MMC connector, or an audio connector. For example, as shown in  FIG.  2 B , a connector  280  which may be connected to an external electronic device (e.g., another electronic device, a charging device, an audio device, etc.) may be disposed at a lower end portion of the electronic device  200 . 
       FIG.  3    is a partial view of the inside of region B shown in  FIG.  2 A .  FIG.  4 A  is a cross-sectional view taken along line P-P shown in  FIG.  2 A .  FIG.  4 B  is an enlarged view of region c of  FIG.  4 A . 
     As shown in  FIG.  3   , the electronic device  200  according to various embodiments disclosed herein may include the side housing  310  configuring a side exterior of the electronic device  200 . In an embodiment, the side housing  310  may be disposed to surround the display module  230  of the electronic device  200 . In some embodiment, the side housing  310  may be formed of a conductive material such as a metal material. For example, the side housing  310  may be formed of a metal material including aluminum (Al). The electronic device  200  may include a protection member  410  disposed to cover a part of the side housing  310  and the display module  230 . Referring to  FIGS.  3  and  4 A , the protection member  410  may be disposed along a side edge of the electronic device  200  to cover a part of the display module  230  and a part of the side housing  310 . For example, the protection member  410  may be disposed along an edge of the display module  230 . In an embodiment, the protection member  410  may include a first portion  411  facing the display module  230 , and a second portion  412  facing the side housing  310 . In an embodiment, the first portion  411  of the protection member  410  may be in a state of covering at least a part of the outer periphery of the display module  230  when the display module  230  is viewed in the -Z direction with reference to  FIG.  4 A . In an embodiment, the second portion  412  of the protection member  410  may extend from the first portion  411  of the protection member  410  to face a part of the side housing  310 . For example, referring to  FIG.  4 A , the second portion  412  of the protection member  410  may be spaced apart from the side housing  310  in the +Z direction with reference to  FIG.  4 A  to face a part of the side housing  310 . The second portion  412  of the protection member  410  is spaced apart from the side housing  310  in the +Z direction with reference to  FIG.  4 A , so that a separation space  430  may be located between the side housing  310  and the second portion  412  of the protection member  410 . As will be described later, a conductive member  340  may be disposed on the protection member  410 . The conductive member  340  may induce a flow of electric charge from the protection member  410  to a ground having a relatively low potential. The conductive member  340  may be disposed to extend from the first portion  411  of the protection member  410  to the second portion  412 . As the separation space  430  is located between the side housing  310  and the conductive member  340  disposed in the second portion  412 , a capacitance (C) may be generated by the separation space  430 , the side housing  310 , and the conductive member  340  disposed in the second portion  412  of the protection member  410 . 
     According to various embodiments, the side housing  310  may be formed of a conductive material and used as an antenna of the electronic device  200 . The side housing  310  may be electrically connected to a communication module included in the electronic device  200  to transmit or receive a communication signal (e.g., an RF signal) to an external device. In an embodiment, the side housing  310  may be electrically connected to the communication module through the antenna IC. The antenna IC may be a component which transmits a radio frequency (RF) signal. The antenna IC may transmit an RF signal processed by the communication module of the electronic device  200  to the side housing  310  serving as an antenna, or transmit an RF signal received from the side housing  310  to the communication module. 
     According to various embodiments, as shown in  FIG.  3   , the side housing  310  may include a plurality of first segment portions  320 . The side housing  310  may be physically segmented into a plurality of parts by the first segment portions  320 . The first segment portions  320  may be defined by spaces formed in the side housing  310  such that one side housing  310  may be segmented into a plurality of parts. In an embodiment, referring to  FIG.  3   , the side housing  310  may be physically segmented into a first side housing  311  and a second side housing  312  by the first segment portions  320 . In some embodiments, the first side housing  311  may be a part of the side housing  310  disposed between edges of the electronic device  200  to form a portion of the exterior of the electronic device  200 . The second side housing  312  may be a part of the side housing  310  disposed at the edges of the electronic device  200  to form a portion the exterior of the electronic device  200 . 
     In an embodiment, the side housing  310  may be electrically segmented as first insulating members  330  disposed in the first segmented portions  320 . The first insulating members  330  may refer to a material having low conductivity or a material having a low dielectric constant. In some embodiments, when the side housing  310  is used as an antenna of the electronic device  200 , an antenna resonant frequency may be determined according to a physical length of the side housing  310 . The side housing  310  may be segmented into a plurality of parts having different lengths by the first insulating members  330  disposed in the first segment portions  320 . As such, the segmented side housings  310  may have different resonant frequencies, respectively. If the side housings  310  having different resonant frequencies are used, communication (e.g., short-distance communication and long-distance communication) in various frequency bands may be possible. 
     According to various embodiments, various electronic components driven by transmitting or receiving an electrical signal may be disposed inside the electronic device  200 . Such components will be referred herein as “electrical objects”. The electrical objects may be formed of a conductive material or may include at least one conductive material. In an embodiment, the electrical objects may be disposed in parts adjacent to the first insulating members  330  which electrically segment the side housing  310  into a plurality of parts. As the electrical objects are disposed adjacent to the first insulating members  330 , a coupling phenomenon may occur between the plurality of segmented side housings  310 . As described above, each of the side housings  310  may have a pre-configured resonant frequency. When a coupling phenomenon occurs between the plurality of side housings  310 , the resonant frequencies of the side housings  310  may be changed. Accordingly, transmission or reception efficiency of a communication signal through the side housings  310  may be reduced. 
     According to various embodiments, the protection member  410  may be formed to have various shapes. In an embodiment, the protection member  410  may include a partition wall portion  413  disposed between the side housing  310  and the outer periphery of the display module  230 . Referring to  FIG.  6 A  to be described later, the partition wall portion  413  may be a structure extending from the second portion  412  of the protection member  410  in the -Z direction with reference to  FIG.  6 A  and positioned between the side housing  310  and the outer periphery of the display module  230 . In an embodiment, the partition wall portion  413  may be disposed to be spaced apart from the side housing  310  so as not to be in contact with the side housing  310 . In another embodiment, the partition wall portion  413  may be disposed between the side housing  310  and the outer periphery of the display module  230  so as to be in contact with the side housing  310 . 
     According to various embodiments, both ends of the display module  230  may move as the first housing  210  and the second housing  220  of the electronic device  200  are folded and unfolded. For example, when the electronic device  200  is folded or unfolded, the both ends of the display module  230  may move with respect to the first housing  210  and the second housing  220 , respectively, with reference to the folding axis A-A. Accordingly, the protection member  410  disposed between the side housing  310  and the display module  230  may be disposed to be spaced apart from the both ends of the display module  230  so as not to be in contact with the both ends of the display module  230 . In an embodiment, the second portion  412  of the protection member  410  may be spaced apart from the display module  230  in the +Z direction with reference to  FIG.  4 A . Therefore, a gap may be defined between the display module  230  and the second portion  412  of the protection member  410 . 
     According to various embodiments, as will be described later, the protection member  410  may be formed of a non-metal material such as synthetic resin, ceramic, or engineering plastic, for example, so that a coupling phenomenon does not occur between the plurality of side housings  310  segmented by the first segment portions  320 . When the protection member  410  is formed of a non-conductive material, electric charge may be accumulated in the protection member  410 . In particular, the protection member  410  may be, as a part frequently contacted when a user grips the electronic device  200 , a part where electric charge is well accumulated. Accordingly, a part of the electric charge accumulated in the protection member  410  may move to the inside of the electronic device  200  through the above-described gap between the protection member  410  and the display module  230 . The remainder of the electric charge accumulated in the protection member  410  may be conducted to the side housing  310  formed of a conductive material, and delivered to a ground having a relatively low potential (e.g. a “ground potential”). The above-described accumulated electric charge may refer to electric charge generated according to an operation of an electronic component disposed inside the electronic device  200 , and may refer to electric charge accumulated outside (or on the surface) of the electronic device  200  and conducted to the inside of the electronic device  200  through a gap disposed in the electronic device  200 . Hereinafter, the accumulated electric charge may be meant to encompass all of the above-described electric charge. 
     In a case where a path through which the electric charge accumulated in the protection member  410  may flow is not provided, an electro static discharge (ESD) phenomenon may occur. An electro static discharge (ESD) phenomenon may refer to an electrical phenomenon caused by instantaneous movement of electric charge accumulated by various factors to another part. An ESD phenomenon may occur in an electronic component due to electric charge accumulated inside or outside the electronic device  200 . Since ESD is accompanied by a strong voltage, when an ESD phenomenon occurs in an electronic component, the electronic component may be damaged. Due to such damage, a problem in which the electronic device  200  does not operate properly or performance is deteriorated may occur. For example, when a user grips the electronic device  200 , electric charge may be well accumulated in the protection member  410  which is frequently contacted. Electric charge accumulated in the protection member  410  moves to the inside of the electronic device  200  through the above-described gap between the protection member  410  and the display module  230 , so that an ESD phenomenon may occur in an electronic component disposed inside the electronic device  200 . In various embodiments disclosed herein, the conductive member  340  formed of a conductive material may be disposed on the protection member  410  to induce a flow of electric charge to a ground having a relatively low potential. 
     According to various embodiments, the electronic device  200  may include a printed circuit board (not shown) electrically connected to at least one ground. The side housing  310  may be electrically connected to the printed circuit board to be electrically connected to the ground. For example, the side housing  310  may be electrically connected to the printed circuit board through a flexible printed circuit board (FPCB) formed of a flexible material. In an embodiment, the electronic device  200  may include the conductive member  340  formed of a conductive material to induce accumulated electric charge to a ground having a relatively low potential. The conductive member  340  may be disposed on the protection member  410 . For example, the conductive member  340  may be disposed to extend from the first portion  411  of the protection member  410  to the second portion  412 . The conductive member  340  may include a first conductive member  341  disposed in the first portion  411  of the protection member  410 , and a second conductive member  342  disposed in the second portion  412  of the protection member  410 . The second conductive member  342  may be connected to the first conductive member  341 . Referring to  FIG.  4 A , the second conductive member  342  may be the conductive member  340  extending from the first portion  411  to the second portion  412 . In an embodiment, referring to  FIG.  3   , the first conductive member  341  may be the conductive member  340  extending along the side housing  310 . The second conductive member  342  may be the conductive member  340  extending from a partial region of the first conductive member  341  to the second portion  412  of the protection member  410 . A flow of electric charge may be induced from the protection member  410  to the side housing  310  connected to the ground through the first conductive member  341  and the second conductive member  342 . For example, after electric charge moves from the first conductive member  341  to an end of the second conductive member  342 , the electric charge may be discharged into the air and move to the side housing  310 . The electric charge having moved to the side housing  310  may move to the ground electrically connected to the side housing  310 . Accordingly, as the accumulated electric charge moves to the ground through the conductive member  340 , an ESD phenomenon to an electronic component may be alleviated or resolved. 
     In the above description, for convenience of description, although the first conductive member  341  and the second conductive member  342  of the conductive member  340  are described as separate configurations, actually, the first conductive member  341  and the second conductive member  342  may be a configuration physically and electrically connected to each other. 
     According to various embodiments, when the conductive member  340  is disposed adjacent to the first insulating members  330 , a coupling phenomenon may occur between the plurality of side housings  310  segmented with reference to the first segment portions  320 . The conductive member  340  may be segmented into a plurality of parts by second segment portions  350  so as to prevent such a phenomenon. Referring to  FIG.  3   , the conductive member  340  may be segmented into a plurality of conductive members  340  with reference to the second segment portions  350 . For example, the first conductive member  341  and the second conductive member  342  configuring the conductive member  340  may be segmented into a plurality of parts with reference to the second segment portions  350 . In an embodiment, the second segment portions  350  may be positioned to correspond to the first segment portions  320 . For example, when the electronic device  200  is viewed in the +Y direction with reference to  FIG.  3   , the first segment portions  320  and the second segment portions  350  may coincide with each other, or one of the first segment portion  320  and the second segment portion  350  may include the other. The conductive members  340  segmented by the second segmentation portions  350  may be disposed on the protection member  410  to correspond to the first side housing  311  and the second side housing  312 , respectively. The first conductive member  341  and the second conductive member  342  may be disposed on the protection member  410  so as to correspond to the segmented side housings  310 . In an embodiment, a part of the conductive members  340  segmented by the second segmented portions  350  may be disposed on the protection member  410  so as to correspond to the first side housing  311  positioned between edges of the electronic device  200 . The remainder of the conductive members  340  segmented by the second segment portions  350  may be disposed on the protection member  410  so as to correspond to the second side housing  312  positioned at the edges of the electronic device  200 . The conductive member  340  is segmented and disposed with reference to the second segment portions  350  corresponding to the first segment portions  320 , so that a coupling phenomenon occurring between the plurality of side housings  310  by the conductive member  340  may be alleviated or resolved. 
     According to various embodiments, referring to  FIG.  4 B , an electronic component configuring the display module  230  may be exposed in a partial region of the display module  230 . In a case where electric charge accumulated in the electronic device  200  is conducted to the electronic component configuring the display module  230 , damage to the electronic component may occur. A second insulating member  540  may be disposed between the protection member  410  and the display module  230  so as to alleviate such a problem. The second insulating member  540  may be disposed to cover a region where the electronic component of the display module  230  is exposed. In an embodiment, the second insulating member  540  may guide the accumulated electric charge to be conducted to the conductive member  340  without being conducted to the region where the electronic component configuring the display module  230  is exposed. For example, referring to  FIG.  4 B , the second insulating member  540  may be disposed to cover the first conductive member  341  disposed in the first portion  411  of the protection member  410 . In addition, the second insulating member  540  may close a gap between the display module  230  and the first portion  411  of the protection member  410 . In a case where electric charge accumulated in the protection member  410  from the outside of the electronic device  200  moves to the inside of the electronic device  200  through the gap between the protection member  410  and the display module  230 , the electric charge may move to the conductive member  340  without moving to the region where the electronic component configuring the display module  230  is exposed. 
     As the second insulating member  540  is disposed to close the gap between the display module  230  and the first portion  411  of the protection member  410 , introduction of dust through the gap between the protection member  410  and the display module  230  may be prevented. 
     According to various embodiments, as shown in  FIG.  4 B , the display module  230  may include a connection member including a bending portion  510  connected to a display panel and extending to the rear surface of the display module  230 , and a protect layer  520  surrounding the outer surface of the bending portion  510 . The connection member may be electrically connected to a printed circuit board disposed on a rear surface (e.g., a surface facing the -Z direction with reference to  FIG.  4 B ) of the display module  230 . The protect layer  520  configuring the connection member may be formed of a flexible material so as to be bendable together with the bending portion  510  in response to the flow of the bending portion  510 . The protect layer  520  may be formed of an insulating material to protect the bending portion  510  from electric charge accumulated in the electronic device  200 . The bending portion  510  and may include a display driver IC (DDI). The bending portion  510  may be integrally configured with a substrate (not shown) disposed on the display module  230 . For example, the display module  230  may include a chip on panel (COP) structure in which the DDI is disposed on the bending portion  510  integrally configured with the substrate of the display module  230 . In some embodiments, the display module  230  may include a chip on film (COF) structure in which the bending portion  510  on which the DDI is disposed is separately manufactured and connected to the substrate of the display module  230 . In this case, the bending portion  510  may be a flexible printed circuit board (FPCB). In an embodiment, referring to  FIG.  4 B , the display module  230  may include a support member  530  formed of a conductive material. The support member  530  may be a ground having a relatively lower potential than its surroundings. For example, the support member  530  may be electrically connected to a printed circuit board connected to at least one ground. Electric charge accumulated in the electronic device  200  may be induced to the support member  530  serving as the ground having a relatively low potential. As electric charge moves to the support member  530 , the electric charge may not be accumulated around the support member  530 . 
     According to various embodiments disclosed in herein, electric charge accumulated in the electronic device  200  may move to a place having a relatively low potential in various manners. In an embodiment, the conductive member  340  disposed on the protection member  410  to correspond to the second side housing  312  may be relatively adjacent to the support member  530  of the display module  230  than the conductive member  340  disposed on the protection member  410  to correspond to the first side housing  311 . Accordingly, a part of the electric charge accumulated in the electronic device  200  may move from the protection member  410  to the support member  530  having a relatively low potential through the conductive member  340 . In addition, another part of the electric charge accumulated in the electronic device  200  may move to the ground connected to the side housing  310  via the protection member  410  and the side housing  310  through the conductive member  340 . 
     According to various embodiments, the conductive member  340  may be disposed on the protection member  410  in various manners. In an embodiment, the conductive member  340  may be manufactured in the form of a thin film tape to be attached to the protection member  410  via an adhesive member such as a bond or a double-sided tape. In some embodiments, the conductive member  340  may be deposited at the protection member  410  in the form of a thin film. For example, the conductive member  340  may be deposited by using various methods such as a chemical vapor deposition (CVD) method or a physical vapor deposition (PVD) method. In another embodiment, the conductive member  340  may be disposed on the protection member  410  by using a laser direct structuring (LDS) method. For example, in a case where the conductive member  340  is formed by using the LDS method, a pattern of the conductive member  340  may be processed, using a laser, on the protection member  410  formed of a non-metal material such as plastic, and the conductive member  340  may be configured in such a manner that a metal material such as copper or nickel is plated on the pattern. In addition, the conductive member  340  may be disposed on the protection member  410  in various manners within a range which can be deformed by a person skilled in the art. 
     According to various embodiments, at least a portion of the first and/or second housings  210  and  220  may be formed of a material other than a metal. For example, portions of the first and/or second housings  210  and  220  adjacent to the first insulating members  330  disposed in the first segment portions  320  of the side housing  310  may be formed of a material other than a metal. Referring to  FIG.  4 A , an internal injection material  420  forming a portion of the first and/or second housings  210  and  220  may be adjacent to the first insulating members  330 . The internal injection molding  420  may be formed of a non-metal material such as synthetic resin, ceramic, or engineering plastic. Accordingly, a coupling phenomenon between the plurality of side housings  310  segmented by the first insulating members  330  may be alleviated or resolved. 
       FIG.  5    is a schematic view of a circuit configured by the side housing  310  and the conductive member  340 .  FIG.  6 A  is a view illustrating a positional relationship between the side housing  310  and the second conductive member  342 , according to various embodiments.  FIG.  6 B  is a view illustrating a positional relationship between the side housing  310  and the second conductive member  342 , according to another embodiment.  FIG.  6 C  is a view illustrating a positional relationship between the side housing  310  and the second conductive member  342 , according to still another embodiment. 
     According to various embodiments, the side housing  310  may be connected to the antenna IC to function as an antenna which transmits and/or receives a communication signal to and/or from an external device. The antenna IC may include a plurality of circuit portions. For example, the antenna IC may include various antenna-related circuits such as a matching circuit configured to perform impedance matching, and a switching circuit configured to allow an antenna to correspond to a wideband characteristic. In an embodiment, the matching circuit may be a circuit including an element such as an inductor or a capacitor to match impedance. In an embodiment, the switching circuit may increase physical lengths of antenna radiators (e.g., the side housing  310 ) by short-circuiting the antenna radiators which are electrically open to each other. The matching circuit and the switching circuit of the circuit portions described above are not interpreted as being limited by their names, but should be understood as a circuit including an element capable of performing a corresponding function. For example, the switching circuit may be referred to as a switching circuit portion, and the matching circuit may be referred to as a variable element portion. In an embodiment, a part of the matching circuit or the switching circuit among the antenna-related circuits may be omitted. 
     In various embodiments disclosed herein, the side housing  310  of the electronic device  200  may be connected to the antenna IC to function as an antenna. In a relationship in which the side housing  310  of the electronic device  200  and the conductive member  340  are arranged to be spaced a predetermined distance (D) apart from each other, a capacitance (C) may be configured between the side housing  310  and the conductive member  340 . Referring to  FIG.  5   , the side housing  310  and the conductive member  340  may configure one circuit including a capacitor and function as an antenna. For example, at least a part of the conductive member  340  may face the side housing  310  in a state of being spaced the predetermined distance (D) apart from the same. In an embodiment, referring to  FIG.  4 A , the conductive member  340  may include the second conductive member  342  extending from a part of the first conductive member  341  to the second portion  412  of the protection member  410 . The second conductive member  342  may be disposed in the second portion  412  of the protection member  410 . As described above, the second portion  412  of the protection member  410  may be positioned to be spaced apart from the side housing  310  in the +Z direction with reference to  FIG.  4 A  in a state of facing the side housing  310 . As the second conductive member  342  is disposed in the second portion  412  of the protection member  410 , the second conductive member  342  may be positioned to be spaced apart from the side housing  310  in the +Z direction with reference to  FIG.  4 A . Accordingly, the separation space  430  may be disposed between the second conductive member  342  and the side housing  310 . The predetermined distance (D) exists between the second conductive member  342  and the side housing  310  and an overlapping region (A) in which the second conductive member  342  and the side housing  310  face each other exists, so that a capacitance (C) may be generated in the electronic device  200  by the second conductive member  342 , the side housing  310 , and the separation space  430 . The capacitance (C) may be used to adjust impedance of an antenna. By adjusting the impedance of the antenna through the capacitance (C), the antenna performance of the electronic device  200  may be improved. 
     In various embodiments disclosed herein, the impedance of the antenna may be adjusted such that the antenna performance of the electronic device  200  may be improved. In an embodiment, the antenna impedance may be adjusted through the matching circuit of the antenna IC. In addition, the impedance of the antenna may be finely adjusted through the capacitance (C) formed by the second conductive member  342  and the side housing  310 . The antenna performance of the electronic device  200  may be improved through appropriate impedance matching. 
     According to various embodiments, as shown in  FIG.  5   , the conductive member  340  may function as an antenna. The side housing  310  and the conductive member  340  may configure one circuit including a capacitor and function as an antenna. Accordingly, the conductive member  340  may transmit or receive a communication signal to or from an external device. The conductive member  340  may adjust a physical length to adjust a resonant frequency of the conductive member  340 . Frequencies of various bands may be transmitted or received by variously changing the resonant frequency. 
     According to various embodiments, a capacitance (C) may be defined as ε,ε o A/D, ε r  may be a dielectric constant of a dielectric material  440  positioned between two objects formed of a conductive material, ε o  may be a dielectric constant when there is a vacuum state between the two objects formed of the conductive material, A may denote an overlapping region where the two objects formed of the conductive material face each other, and D may denote a predetermined distance between the two objects formed of the conductive material. The capacitance (C) may be adjusted to various values by changing the above-described variables. In an embodiment, the capacitance (C) may be adjusted according to a size of the separation space  430  disposed between the second conductive member  342  and the side housing  310 . For example, when a predetermined distance (D) between the second conductive member  342  and the side housing  310  increases, the capacitance (C) may decrease. Conversely, when the predetermined distance (D) between the second conductive member  342  and the side housing  310  decreases, the capacitance (C) may increase. In addition, the capacitance (C) may be adjusted according to an overlapping region (A) in which the second conductive member  342  and the side housing  310  face and overlap each other. For example, when the overlapping region (A) of the second conductive member  342  and the side housing  310  increases, the capacitance (C) may increase. Conversely, when the overlapping region of the second conductive member  342  and the side housing  310  decreases, the capacitance (C) may decrease. 
     According to various embodiments, as shown in  FIG.  6 A , the dielectric material  440  may be disposed in the separation space  430 . In an embodiment, the capacitance (C) may be adjusted through the dielectric material  440 . For example, in a mounting structure of the electronic device  200 , it may be difficult to adjust a predetermined distance (D) between the second conductive member  342  and the side housing  310 , and an overlapping region (A) in which the second conductive member  342  and the side housing  310  face each other. In this case, the capacitance (C) formed by the second conductive member  342  and the side housing  310  may be adjusted by disposing the dielectric material  440  in the separation space  430 . 
     According to various embodiments, the dielectric material  440  may refer to a part of the side housing  310 . Referring to  FIG.  6 B , the dielectric material  440  may refer to the partition wall portion  413  of the protection member  410  positioned in the separation space  430  disposed between the second conductive member  342  and the side housing  310 . 
     According to various embodiments, as shown in  FIG.  6 C , the partition wall portion  413  and the dielectric material  440  may be disposed together in the separation space  430 . In this case, the capacitance (C) may increase compared to a case in which only the partition wall portion  413  or the dielectric material  440  is disposed in the separation space  430 . 
     According to various embodiments disclosed herein, the conductive member  340  may be attached to the protection member  410  to induce a flow of electric charge accumulated in the electronic device  200  from the protection member  410  to a ground included in the electronic device  200 . 
     A part of the conductive member  340  may be positioned adjacent to the side housing  310  to face the side housing  310 . In an embodiment, the conductive member  340  may include the second conductive member  342  extending from a part of the first conductive member  341  to the second portion  412  of the protection member  410 . The second conductive member  342  may be spaced a predetermined distance (D) apart from the side housing  310  and disposed in the second portion  412  of the protection member  410 . Therefore, the separation space  430  may be disposed between the second conductive member  342  and the side housing  310 . Accordingly, a capacitance (C) using, as variables, the predetermined distance (D) between the second conductive member  342  and the side housing  310 , the overlapping region (A) of the second conductive member  342  and the side housing  310 , and the dielectric constant of the dielectric material  440  positioned between the second conductive member  342  and the side housing  310  may be generated. The impedance of the antenna may be finely adjusted through the capacitance (C) formed by the second conductive member  342  and the side housing  310 . The antenna performance of the electronic device  200  may be improved through appropriate impedance matching. 
     According to various embodiments, when the electronic device  200  is in a folded state, the side housing  310  of the first housing  210  and the side housing  310  of the second housing  220  may face each other. For example, referring to  FIG.  2 C , the first housing  210  and the second housing  220  may be folded such that the first segment portion  320  disposed on the side housing  310  of the first housing  210  and the first segment portion  320  disposed on the side housing  310  of the second housing  220  coincide with each other. In this case, a coupling phenomenon may occur between the side housing  310  of the first housing  210  and the side housing  310  of the second housing  220 . Accordingly, resonant frequencies of the side housing  310  of the first housing  210  and the side housing  310  of the second housing  220  may be changed. Accordingly, transmission or reception efficiency of a communication signal through the side housings  310  may be reduced. According to various embodiments disclosed herein, the conductive member  340  may be disposed at least one of the side housing  310  of the first housing  210  and the side housing  310  of the second housing  220 . Among the conductive members  340 , the second conductive member  342  facing the side housing  310  may be disposed such that a predetermined distance (D) spaced apart from the side housing  310  and an overlapping region (A) exist. Therefore, a capacitance (C) may be generated between the second conductive member  342  and the side housing  310 . The antenna performance of the electronic device  200  may be improved by matching the impedance of the antenna through the capacitance (C). 
       FIGS.  7 A to  7 C  are views illustrating a change in performance of an antenna due to a conductive member, according to various embodiments disclosed herein. 
     According to various embodiments, in  FIGS.  7 A to  7 C , the X-axis represents a resonant frequency measured in gigahertz (Ghz), and the Y-axis represents an input reflection coefficient S 11  measured in decibels (dB). The input reflection coefficient S 11  may be, as a coefficient indicating how much a value input to a first port of the antenna IC has been output back to the first port, a coefficient indicating how much the input value has been reflected. The lower a numerical value of the input reflection coefficient S 11 , the smaller the loss (reflection) that has occurred. Therefore, the lower the numerical value of the input reflection coefficient S 11 , the better the antenna performance 
     According to various embodiments, referring to  FIGS.  7 A and  7 B , it may be viewed that the input reflection coefficient S 11  of the antenna is changed according to a change in an overlapping region (A) and a predetermined distance (D) between the second conductive member  342  and the side housing  310 . Referring to  FIG.  7 A  along with  FIGS.  6 A- 6 C , it may be viewed that as the predetermined distance (D) between the second conductive member  342  and the side housing  310  decreases, the numerical value of the input reflection coefficient S 11  decreases. In addition, referring to  FIG.  7 B  along with  FIGS.  6 A- 6 C , it may be viewed that as the overlapping region (A) of the second conductive member  342  and the side housing  310  increases, the numerical value of the input reflection coefficient S 11  decreases. In various embodiments disclosed herein, the antenna performance of the electronic device  200  may be improved through a capacitance (C). For example, the numerical value of the input reflection coefficient S 11  may be lowered by adjusting the predetermined distance (D) between the second conductive member  342  and the side housing  310  and the overlapping region (A) of the second conductive member  342  and the side housing  310 . As a result of lowering the numerical value of the input reflection coefficient S 11 , the antenna performance of the electronic device  200  may be improved. 
     According to various embodiments, as shown in  FIG.  7 C , the conductive member  340  may function as an antenna by being electrically connected to the antenna IC through the side housing  310 . The conductive member  340  may be in the form of an antenna branched from an antenna of the side housing  310 . The conductive member  340  and the side housing  310  may form resonant frequencies of different bands, based on physical lengths, respectively. The electronic device  200  may expand an antenna bandwidth as a frequency band  620  of the conductive member  340  is added to a frequency band  610  of the side housing  310 . The electronic device  200  may transmit or receive frequencies of various bands by variously changing resonant frequencies according to physical lengths of the side housing  310  and the conductive member  340 .

According to an embodiment, the angle or the distance between the first housing  710  and the second housing  720  may vary depending on whether the electronic device  700  is in an unfolded state, a folded state, or an intermediate state. 
     According to various embodiments, the first housing  710  may include, in the unfolded state of the electronic device  700 , a first surface  711  connected to the hinge device (e.g., the hinge device  320  of  FIG.  3   ) and disposed to be oriented to the front surface of the electronic device  700 , a second surface  712  oriented in a direction opposite to the first surface  711 , and/or a first side member  713  surrounding at least a part of a first space between the first surface  711  and the second surface  712 .

In an embodiment, the first protection frame  713   a  and the second protection frame  723   a  may be omitted. 
     According to various embodiments, the hinge housing  810  (e.g., a hinge cover) may be disposed between the first housing  710  and the second housing  720 , and may be disposed to cover a part (e.g., at least one hinge module) of the hinge device (e.g., the hinge device  320  of  FIG.  3   ) disposed on the hinge housing  810 .

For example, when the electronic device  700  is in the unfolded state, at least a part of the hinge housing  810  may be covered by the first housing  710  and the second housing  720  and not be substantially exposed. According to an embodiment, when the electronic device  700  is in the folded state, at least a part of the hinge housing  810  may be exposed to the outside between the first housing  710  and the second housing  720 . According to an embodiment, in the intermediate state in which the first housing  710  and the second housing  720  are folded with each other by a predetermined angle (folded with a certain angle), the hinge housing  810  may be at least partially exposed to the outside of the electronic device  700  between the first housing  710  and the second housing  720 . For example, an area in which the hinge housing  810  is exposed to the outside, may be smaller than that in a case in which the electronic device  700  is completely folded.
