Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation application, claiming priority under §365(c), of an International application No. PCT/KR2022/000638, filed on Jan. 13, 2022, which was based on and claimed the benefit of a Korean patent application number 10-2021-0007832, filed on Jan. 20, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety. 
     TECHNICAL FIELD 
     The disclosure relates to an antenna and an electronic device including the same. 
     BACKGROUND ART 
     With the development of wireless communication technology, electronic devices (e.g., an electronic device for communication) are widely used in everyday life, and thus the use of contents is increasing exponentially. Due to the rapid increase in the use of contents, the network capacity is gradually reaching the limit, and after the commercialization of 4th-generation (4G) communication systems, next-generation communication systems (e.g., a 5th-generation (5G) communication system, a pre-5G communication system, or a new radio (NR) communication system) using a super-high frequency (e.g., mmWave) band (e.g., 3 GHz to 300 GHz band) is now studied in order to satisfy the increasing demands of radio data traffic. 
     The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. 
     DISCLOSURE 
     Technical Problem 
     Next-generation wireless communication technologies are currently developed to permit signal transmission/reception using frequencies in the range of 3 GHz to 100 GHz, address a high free space loss due to frequency characteristics, implement an efficient mounting structure for increasing an antenna gain, and realize a related new antenna module (e.g., an antenna structure). The antenna module may include an antenna module of an array form in which various numbers of antenna elements (e.g., conductive patches) are disposed at regular intervals. These antenna elements may be disposed to form a beam pattern in any one direction inside the electronic device. For example, the antenna module may be disposed such that a beam pattern is formed toward at least a portion of at least one of the front surface, the rear surface, or the side surface in the inner space of the electronic device. 
     Meanwhile, various electronic components (e.g., a key button device and/or at least one sensor module) as well as the antenna module may be disposed in the electronic device, and such electronic components may have an appropriate arrangement structure to perform their functions without impairing the radiation performance of the antenna module. 
     However, in the electronic device that is gradually becoming slimmer, an arrangement space that allows the antenna module to be disposed in the inner space of the electronic device without deterioration of radiation performance due to interference of other electronic components is gradually reduced. Thus, the electronic device requires an efficient antenna arrangement structure with other electronic components without deterioration of radiation performance. 
     Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an antenna having an efficient arrangement structure with other electronic components and an electronic device including the same. 
     Another aspect of the disclosure is to provide an antenna disposed together with other electronic components without deterioration in radiation performance and thereby helping to slim an electronic device, and an electronic device including the same. 
     Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments. 
     Technical Solution 
     In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device includes a housing; an antenna structure disposed in an inner space of the housing and including a substrate having a first substrate surface facing toward a first direction, a second substrate surface facing toward a direction opposite to the first substrate surface, and a ground layer disposed in a space between the first substrate surface and the second substrate surface, at least one conductive patch disposed between the ground layer and the first substrate surface or to be exposed to the first substrate surface, at least one power feeder disposed at a position of the at least one conductive patch, and at least one electrical connection structure disposed at the substrate including: a first conductive via disposed to pass through the at least one conductive patch and the ground layer, and a second conductive via passing through the at least one conductive patch and electrically connected to the ground layer; an electronic component disposed on the first substrate surface and disposed to overlap at least in part with the at least one conductive patch when the first substrate surface is viewed from above, the electronic component being electrically connected to a main board through the at least one electrical connection structure; and a wireless communication circuit disposed in the inner space, electrically connected to the at least one power feeder, and configured to form a beam pattern in the first direction through the at least one conductive patch. 
     Advantageous Effects 
     The antenna according to an embodiment of the disclosure can help to utilize an arrangement space because at least one electronic component (e.g., a key button device) is disposed together through at least a portion of an antenna structure without degradation of radiation performance. 
     Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the disclosure.

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 cellular 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 SIM  196 .

     Upon transmission, the first RFIC  222  may convert a baseband signal generated by the first communication processor  212  to a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network  292  (e.g., legacy network). Upon reception, an RF signal may be obtained from the first cellular network  292  (e.g., legacy network) through an antenna (e.g., the first antenna module  242 ) and be preprocessed through an RFFE (e.g., the first RFFE  232 ). The first RFIC  222  may convert the preprocessed RF signal to a baseband signal so as to be processed by the first communication processor  212 . 
     Upon transmission, the second RFIC  224  may convert a baseband signal generated by the first communication processor  212  or the second communication processor  214  to an RF signal (hereinafter, 5G Sub6 RF signal) of a Sub6 band (e.g., 6 GHz or less) to be used in the second cellular network  294  (e.g., 5G network). Upon reception, a 5G Sub6 RF signal may be obtained from the second cellular network  294  (e.g., 5G network) through an antenna (e.g., the second antenna module  244 ) and be pretreated through an RFFE (e.g., the second RFFE  234 ). The second RFIC  224  may convert the preprocessed 5G Sub6 RF signal to a baseband signal so as to be processed by a corresponding communication processor of the first communication processor  212  or the second communication processor  214 . 
     The third RFIC  226  may convert a baseband signal generated by the second communication processor  214  to an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network  294  (e.g., 5G network). Upon reception, a 5G Above6 RF signal may be obtained from the second cellular network  294  (e.g., 5G network) through an antenna (e.g., the antenna  248 ) and be preprocessed through the third RFFE  236 . The third RFIC  226  may convert the preprocessed 5G Above6 RF signal to a baseband signal so as to be processed by the second communication processor  214 . According to one embodiment, the third RFFE  236  may be formed as part of the third RFIC  226 . 
     According to an embodiment, the electronic device  101  may include a fourth RFIC  228  separately from the third RFIC  226  or as at least part of the third RFIC  226 . In this case, the fourth RFIC  228  may convert a baseband signal generated by the second communication processor  214  to an RF signal (hereinafter, an intermediate frequency (IF) signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and transfer the IF signal to the third RFIC  226 . The third RFIC  226  may convert the IF signal to a 5G Above6RF signal. Upon reception, the 5G Above6RF signal may be received from the second cellular network  294  (e.g., a 5G network) through an antenna (e.g., the antenna  248 ) and be converted to an IF signal by the third RFIC  226 . The fourth RFIC  228  may convert an IF signal to a baseband signal so as to be processed by the second communication processor  214 . 
     According to one embodiment, the first RFIC  222  and the second RFIC  224  may be implemented into at least part of a single package or a single chip. According to one embodiment, the first RFFE  232  and the second RFFE  234  may be implemented into at least part of a single package or a single chip. According to one embodiment, at least one of the first antenna module  242  or the second antenna module  244  may be omitted or may be combined with another antenna module to process RF signals of a corresponding plurality of bands. 
     According to one embodiment, the third RFIC  226  and the antenna  248  may be disposed at the same substrate to form a third antenna module  246 . For example, the wireless communication module  192  or the processor  120  may be disposed at a first substrate (e.g., main PCB). In this case, the third RFIC  226  is disposed in a partial area (e.g., lower surface) of the first substrate and a separate second substrate (e.g., sub PCB), and the antenna  248  is disposed in another partial area (e.g., upper surface) thereof; thus, the third antenna module  246  may be formed. By disposing the third RFIC  226  and the antenna  248  in the same substrate, a length of a transmission line therebetween can be reduced. This may reduce, for example, a loss (e.g., attenuation) of a signal of a high frequency band (e.g., about 6 GHz to about 60 GHz) to be used in 5G network communication by a transmission line. Therefore, the electronic device  101  may improve a quality or speed of communication with the second cellular network  294  (e.g., 5G network). 
     According to one embodiment, the antenna  248  may be formed in an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC  226  may include a plurality of phase shifters  238  corresponding to a plurality of antenna elements, for example, as part of the third RFFE  236 . Upon transmission, each of the plurality of phase shifters  238  may convert a phase of a 5G Above6 RF signal to be transmitted to the outside (e.g., a base station of a 5G network) of the electronic device  101  through a corresponding antenna element. Upon reception, each of the plurality of phase shifters  238  may convert a phase of the 5G Above6 RF signal received from the outside to the same phase or substantially the same phase through a corresponding antenna element. This enables transmission or reception through beamforming between the electronic device  101  and the outside. 
     The second cellular network  294  (e.g., 5G network) may operate (e.g., stand-alone (SA)) independently of the first cellular network  292  (e.g., legacy network) or may be operated (e.g., non-stand alone (NSA)) in connection with the first cellular network  292 . For example, the 5G network may have only an access network (e.g., 5G radio access network (RAN) or a next generation (NG) RAN and have no core network (e.g., next generation core (NGC)). In this case, after accessing to the access network of the 5G network, the electronic device  101  may access to an external network (e.g., Internet) under the control of a core network (e.g., an evolved packed core (EPC)) of the legacy network. Protocol information (e.g., LTE protocol information) for communication with a legacy network or protocol information (e.g., new radio (NR) protocol information) for communication with a 5G network may be stored in the memory  130  to be accessed by other components (e.g., the processor  120 , the first communication processor  212 , or the second communication processor  214 ).

According to an embodiment, the electronic device  300  may include a wireless communication circuit (e.g., the wireless communication module  192  in  FIG. 1 , the RFIC  452  in  FIG. 4B , or the wireless communication circuit  595  in  FIG. 6A ) electrically connected to the conductive patches  510  and  520  of the antenna structure  500 . According to an embodiment, the wireless communication circuit  595  may be disposed on the second substrate surface  5902 . In some embodiments, the wireless communication circuit  595  may be electrically connected to the conductive patches  510  and  520  disposed in the substrate  590  through an electrical connection member (e.g., an electrical connection member  597  in  FIG. 17 ) spaced apart from the substrate  590  in the inner space of the electronic device  300 . According to an embodiment, the conductive patches  510  and  520  may include a first conductive patch  510  and a second conductive patch  520  spaced apart from each other at a predetermined interval.

     According to various embodiments, the substrate  590  of the antenna structure  500  may be disposed in a manner to face the side member  320  in the inner space of the electronic device  300 . For example, in the inner space of the electronic device  300 , the substrate  590  may be disposed in order for the first substrate surface  5901  to face the side member  320 , thereby inducing a beam pattern of the antenna structure  500  to be formed in the first direction (the direction {circle around ( 1 )}) toward which the side member  320  faces. According to an embodiment, the substrate  590  may be disposed on a mounting portion  3212  provided through a structural shape of the support member  3211 . According to an embodiment, the substrate  590  may be fixed to the mounting portion  3212  via a conductive plate  550  for supporting the substrate side surface  5903  and/or the second substrate surface  5902 . For example, the substrate  590  may be fixed to the conductive plate  550  by taping or bonding, and the conductive plate  550  may be fixed to the mounting portion  3212  or the side member  320  through a fastening member such as a screw (S). 
     According to various embodiments, the key button device  600  may include a key button  610  and key modules  620  and  630 . The key button  610  is exposed to be visible from the outside at least partially through an opening  321  formed in the side member  320  and has pressing protrusions  611  and  612  protruding in a substrate direction (a negative x-axis direction). The key modules  620  and  630  are disposed on the first substrate surface  5901  to be switched in response to a pressing operation of the key button  610 . According to an embodiment, the key button  610  is disposed to be visible to the outside of the electronic device  300  and allows at least one function of the electronic device  300  to be performed through a user manipulation (e.g., press or touch). According to an embodiment, the at least one function may include various functions such as a volume up/down function, a wakeup function, a sleep function, or a power on/off function.

For example, when the first pressing protrusion  611  presses the first conductive contact  622  through the pressing of the key button  610 , a switching operation may be performed through a circuit structure configured in the first button substrate  621 . In some embodiments, when the first conductive contact  622  has a metal dome, a carbon contact, which is a circuit structure disposed above and spaced apart from the first button substrate  621 , may be electrically connected through the deformation of the metal dome by the pressing of the first pressing protrusion  611 , and thereby the switching operation may be performed. In some embodiments, when the key button  610  and the first pressing protrusion  611  are formed at least in part of a conductive material, the first button substrate  621  may perform the switching operation by detecting a change in capacitance by a user&#39;s touch. According to an embodiment, the second key module  630  may include a second button substrate  631  (e.g., a key pad) disposed on the first substrate surface  5901 , and a second conductive contact  632  (e.g., a metal dome) disposed on the second button substrate  631  and adjacent to or in contact with the second pressing protrusion  612 . According to an embodiment, the second key module  630  may be disposed on the first substrate surface  5901  in substantially the same manner as that of the first key module  620 . 
     Although the key button device  600  according to an embodiment of the disclosure includes one key button  610  for pressing the key modules  620  and  630  through the pressing protrusions  611  and  612  spaced apart from each other at a specified interval, this is not construed as a limitation. For example, the key button device  600  may include two key buttons respectively disposed at positions corresponding to the pressing protrusions  611  and  612 . In some embodiments, when three or more conductive patches are disposed in the antenna structure  500 , the key button device  600  may include three or more key modules and at least one key button for pressing the key modules. In some embodiments, the key button device  600  may be replaced with at least one other electronic component. For example, the at least one other electronic component may include a sensor module (e.g., the sensor module  319  in  FIG. 3B ), a camera module (e.g., the camera module  312  in  FIG. 3B ), a speaker device (e.g., the external speaker  307  in  FIG. 3A ), a microphone device (e.g., the microphone  303  in  FIG. 3A ), or a connector port (e.g., the connector hole  308  in  FIG. 3A ). In some embodiments, the at least one other electronic component may be disposed to correspond to the outside of the electronic device  300  through the structural shape of the housing  310 . In some embodiments, the substrate  590  of the antenna structure  500  may be disposed to face a rear cover (e.g., the rear plate  311  in  FIG. 3B ) of the electronic device  300  such that a beam pattern is formed in a direction (e.g., the negative z-axis direction in  FIG. 3B ) toward which the rear surface faces. In this case, the key button  610  of the key button device  600  may be exposed to be seen from the outside on the rear surface (e.g., the rear surface  310 B in  FIG. 3B ) of the electronic device  300 . 
     According to various embodiments, the antenna structure  500  may include an electrical connection structure for electrically connecting the key button device  600  disposed on the first substrate surface  5901  of the substrate  590  to the main board (e.g., the printed circuit board  340  in  FIG. 3C ) of the electronic device  300 . According to an embodiment, the electrical connection structure may be disposed through an internal structure of the substrate, and a detailed description will be given below. 
     The electronic device  300  according to embodiments of the disclosure includes the antenna structure  500  and the key button device  600  disposed to overlap at least in part with the antenna structure  500 , and has a mutual arrangement structure to reduce the radiation performance degradation caused by the key button device  600 , thereby realizing an efficient use of a component mounting space without affecting the radiation performance.

According to an embodiment, the conductive patch  510  may be disposed in an insulating layer  591  between the first and second substrate surfaces  5901  and  5902  or disposed to be exposed through at least a portion of the first substrate surface.

According to an embodiment, the power feeder  511  may include a conductive via disposed to at least partially pass through a first through-hole  5921  formed in the ground layer  592 .

According to an embodiment, the key button device  600  may include the first key module  620  (hereinafter, the ‘key module’) disposed on the first substrate surface  5901 , and the key button  610  for operating the key module  620  through a user&#39;s manipulation. According to an embodiment, at least a portion of the key button  610  may be exposed through an opening (e.g., the opening  321  in  FIG. 5A ) formed in at least a portion of the side member (e.g., the side member  320  in  FIG. 5A ) so as to be visible from the outside and be manipulatable. According to an embodiment, the key button  610  may include the first pressing protrusion  611  (hereinafter, the ‘pressing protrusion’) that is extended to be in contact with or close to the key module  620 . According to an embodiment, the first key module  620  may include the first button substrate  621  (e.g., a key pad) disposed on the first substrate surface  5901 , and the first conductive contact  622  (hereinafter, the ‘conductive contact’) disposed on the first button substrate  621  (hereinafter, the ‘button substrate’). According to an embodiment, the conductive contact  622  may include a metal dome that is pressed through the pressing protrusion  611 . 
     According to various embodiments, the antenna structure  500  may include at least a part of an electrical connection structure for connecting the key button device  600  to the main board (e.g., the printed circuit board  340  in  FIG. 3C ) of the electronic device (e.g., the electronic device  300  in  FIG. 5A ). According to an embodiment, the electrical connection structure may include one or more conductive vias  623  and  624  disposed to penetrate at least in part the substrate  590 . According to an embodiment, the one or more conductive vias  623  and  624  may include a first conductive via  623  (e.g., a signal via) disposed in the insulating layer  591  of the substrate  590  so as to pass through a second through-hole  5101  formed in the conductive patch  510  and a third through-hole  5922  formed in the ground layer  592  from the key module  620 , and a second conductive via  624  (e.g., a ground via) disposed to penetrate the conductive patch  510  from the key module  620  and electrically connected to the ground layer  592 . According to an embodiment, the first conductive via  623  may be disposed to remain electrically isolated from the conductive patch  510  and the ground layer  592 . According to an embodiment, the second conductive via  624  may remain electrically isolated from the conductive patch  510 . In another embodiment, the second conductive via  624  may be connected to the ground layer  592  while being electrically connected to the conductive patch  510 . According to an embodiment, the first conductive via  623  may be electrically connected to a connector  596  (e.g., a B2B connector) for the key button device disposed on the second substrate surface  5902  through a second wiring structure  5932  (e.g., an electrical wiring) disposed in the insulating layer  591  between the ground layer  592  and the second substrate surface  5902 . In some embodiments, the conductive patch  510  and/or the wireless communication circuit  595  may be electrically connected to the main board (e.g., the printed circuit board  340  in  FIG. 3C ) through another electrical connection member (e.g., FRC; flexible printed circuit board (FPCB) type RF cable, or a coaxial cable) that is extended from the substrate  590  and provided separately from the connector  596 . In some embodiments, when the wireless communication circuit  595  is disposed at a location other than the substrate  590  in the inner space of the electronic device (e.g., the electronic device  300  in  FIG. 5A ), the first wiring structure  5931  may also be electrically connected to the connector  596 , and thereby an RF signal of the conductive patch  510  and a key input signal of the key module  620  may be transmitted to the main board (e.g., the printed circuit board  340  in  FIG. 3C )through the connector  596 . In some embodiments, although the wireless communication circuit  595  is disposed on the second substrate surface  5902 , the RF signal of the conductive patch  510  and the key input signal of the key module  620  may be transmitted to the main board (e.g., the printed circuit board  340  in  FIG. 3C ) through the connector  596 . 
       FIG. 6C  is a cross-sectional view partially illustrating an antenna structure including a key button device according to various embodiments of the disclosure. Compared to the configuration shown in  FIG. 6A , the antenna structure  500  may further include at least one conductive dummy patch  5111  disposed in the insulating layer  591  between the first substrate surface  5901  and the conductive patch  510 . According to an embodiment, the dummy patch  5111  may be spaced apart from the conductive patch  510  at a predetermined interval so as to be capacitively coupled to the conductive patch  510 . According to an embodiment, the dummy patch  5111  may have a smaller size than the conductive patch  510 . In some embodiments, the dummy patch  5111  may have a size substantially the same as or larger than the conductive patch  510 . According to an embodiment, the dummy patch  5111  may help to expand the bandwidth of the operating frequency band of the antenna structure  500  without degrading the radiation performance. 
       FIGS. 7A and 7B  are views illustrating the arrangement structure of conductive vias according to various embodiments of the disclosure. 
       FIGS. 7A and 7B  are top views of the substrate  590  of the antenna structure  500 . In order to explain the arrangement positions of the conductive vias  623  and  624  connected to the key module  620 , the key button (e.g., the key button  610  in  FIG. 6A ) is not depicted. 
     Referring to  FIG. 7A , the antenna structure  500  may include the conductive vias  623  and  624  disposed in the substrate  590  and electrically connected to the key module  620 . According to an embodiment, the conductive vias  623  and  624  may include the first conductive via  623  that transmits the key input signal of the key module  620 , and the second conductive via  624  that connects the key module  620  and the ground layer (e.g., the ground layer  592  in  FIG. 6A ). According to an embodiment, as the conductive vias  623  and  624  are disposed in a region overlapping with the center C of the conductive patch  510  or a position close to the center C when the substrate  590  is viewed from above, it may be advantageous in reducing the radiation performance degradation of the antenna structure  500 . For example, a patch antenna including the conductive patch  510  has an electric field distribution that is symmetrical on the left and right with respect to the vertical direction of the operating polarized wave, and thereby it may have, at the center C of the conductive patch  510 , a virtual ground plane (a virtual short plane or e-plane) where the electric field becomes zero in the vertical direction of the polarized wave. Therefore, at that location, because there is no electric field between the conductive patch  510  and the ground layer (e.g., the ground layer  592  in  FIG. 6A ), the radiation performance degradation of the antenna structure  500  can be reduced even if the conductive vias  623  and  624  are disposed. In another example, because the patch antenna including the conductive patch  510  has a stronger electric field from the center C to edge portions, a metal structure (e.g., the conductive vias  623  and  624 ) positioned at the center of the conductive patch  510  may relatively less affect the radiation performance than positioned in the edge portions. 
     According to various embodiments, using the structural characteristics of the patch antenna including the conductive patch  510 , the conductive vias  623  and  624  according to embodiments of the disclosure may be disposed to overlap with a point close to the center C of the conductive patch  510  when the substrate  590  is viewed from above. According to an embodiment, when the substrate  590  is viewed from above, the first conductive via  623  and the second conductive via  624  may be disposed at positions that overlap with points symmetrical to each other with respect to the center C of the conductive patch  510 . Although the two conductive vias  623  and  624  are illustrated as being spaced apart from each other with respect to the center C for convenience of description, this is not construed as a limitation. For example, the two conductive vias  623  and  624  may be disposed to be in contact with each other with respect to the center C. 
     With respect to  FIG. 7B , one (e.g., the second conductive via  624 ) of the two conductive vias  623  and  624  may be disposed at a position overlapping with the center C of the conductive patch  510  when the substrate  590  is viewed from above. For example, the second conductive via  624  connecting the key module  620  to the ground layer (e.g., the ground layer  592  in  FIG. 6A ) of the substrate  590  may be disposed at a position overlapping with the center C. In an embodiment, because the first conductive via  623  is more advantageous as it is disposed closer to the center C, it may be disposed at a position in contact with the second conductive via  624 . In another embodiment, the first conductive via  623  may be disposed at a position overlapping with the center C, and the second conductive via  624  may be disposed at a position closest to the first conductive via  623  as much as possible. 
       FIGS. 7C and 7D  are views illustrating the arrangement structure of power feeders according to various embodiments of the disclosure. 
     Referring to  FIG. 7C , an antenna structure  500 - 1  may include two power feeders  511  and  512  disposed in the conductive patch  510 , thereby operating to have dual polarization. In this case, when the substrate  590  is viewed from above, the antenna structure  500 - 1  may include a first power feeder  511  disposed on a first virtual line L 1  passing through the center C, and a second power feeder  512  disposed on a second virtual line L 2  passing through the center C and crossing the first virtual line L 1  at a specified angle. According to an embodiment, the specified angle may include 90 degrees. According to an embodiment, the antenna structure  500 - 1  that includes the two power feeders  511  and  512  and supports the dual polarization may also include the conductive vias  623  and  624  disposed at positions overlapping with points close to the center C when the substrate  590  is viewed from above. According to an embodiment, the conductive vias  623  and  624  may be symmetrically disposed with respect to the center C, or alternatively one conductive via  624  may be disposed at a position overlapping with the center C, and the other conductive via  623  may be disposed to be in close proximity to the conductive via  624 . In an embodiment, the conductive vias  623  and  624  may be disposed at positions overlapping with points close to the center C without overlapping with the first and second virtual lines L 1  and L 2 . This is because, when the antenna structure  500 - 1  supports polarization diversity, the conductive patch  510  generates two perpendicular polarized waves, the virtual ground planes where the electric field becomes zero become perpendicular to each other at the center C of the conductive patch  510 , and thereby the center C of the conductive patch  510  operates as a virtual GND point. In some embodiments, the conductive vias  623  and  624  may be arranged in a direction perpendicular to the illustrated arrangement direction. 
     Referring to  FIG. 7D , an antenna structure  500 - 2  may operate as a dual-feed dual-polarization antenna that further includes a third power feeder  513  disposed on the first virtual line L 1  to be symmetrical with the first power feeder  511  with respect to the center C of the conductive patch  510  and a fourth power feeder  514  disposed on the second virtual line L 2  to be symmetrical with the second power feeder  512  with respect to the center C. Even in this case, the conductive vias  623  and  624  may be disposed in the substrate  590  at positions overlapping with points close to the center C, thereby not only reducing deterioration in radiation performance of the antenna structure  500 - 2 , but also helping to implement an improved arrangement structure of the key button device (e.g., the key button device  600  in  FIG. 6A ). 
       FIG. 8  is a graph illustrating the radiation performance of an antenna structure depending on the presence or absence of a key button device in the configuration of  FIG. 7C  according to an embodiment of the disclosure. 
     Referring to  FIG. 8 , it can be seen that, in the antenna structure  500 - 1  of  FIG. 7C  supporting dual polarization, the gains of vertical polarization (graph  801 ) and horizontal polarization (graph  802 ) when the key button device (e.g., the key button device  600  in  FIG. 6A ) is disposed on the substrate (e.g., the substrate  590  in  FIG. 7C ) through the arrangement structure of two conductive vias (e.g., the conductive vias  623  and  624  in  FIG. 7C ) do not change significantly enough to affect the radiation performance in an operating frequency band  810  (e.g., about 28 GHz) compared to the gains of vertical polarization (graph  803 ) and horizontal polarization (graph  804 ) when the key button device  600  is not disposed on the substrate  590 . This means that, even if the conductive patch  510  of the antenna structure  500 - 1  and the key button device  600  are disposed to overlap with each other, the radiation performance of the antenna structure  500 - 1  is not substantially deteriorated through the two conductive vias  623  and  624  are arranged at the center C or close to the center C. 
       FIG. 9  is a diagram illustrating the arrangement structure of conductive vias according to an embodiment of the disclosure. 
     Referring to  FIG. 9 , the antenna structure  500  may include the conductive vias  623  and  624  disposed in the substrate  590  and electrically connected to the key module  620 . According to an embodiment, the conductive vias  623  and  624  may include the first conductive via  623  that transmits the key input signal of the key module  620 , and the second conductive via  624  that connects the key module  620  and the ground layer (e.g., the ground layer  592  in  FIG. 6A ). According to an embodiment, when the substrate  590  is viewed from above, the antenna structure  500  may include the second conductive via  624  disposed at a position overlapping with the center C of the conductive patch  510 , and the first conductive via  623  disposed at a position having a specified separation distance D 1  from the second conductive via  624 . According to an embodiment, when the substrate  590  is viewed from above, the first conductive via  623  may be disposed within a distance of about 30% of a linear distance (D) from the second conductive via  624  disposed at the center C of the conductive patch  510  to the end of the conductive patch  510 . According to an embodiment, even when both the first conductive via  623  and the second conductive via  624  are disposed in a region that does not overlap with the center C of the conductive patch  510 , each of the first and second conductive vias  623  and  624  may be disposed such that each separation distance D 1  from the center C is within a distance of 30% of the linear distance D between the center C of the conductive patch  510  and the end of the conductive patch. 
       FIG. 10  is a graph illustrating the radiation performance of an antenna structure depending on a separation distance between two conductive vias of  FIG. 9  according to an embodiment of the disclosure. 
     Referring to  FIG. 10 , it can be seen that the gain of the antenna structure (e.g., the antenna structure  500  in  FIG. 9 ) decreases in the operating frequency band  1010  (e.g., about 28 GHz band) when the separation distance (e.g., the separation distance D 1  in  FIG. 9 ) of the first conductive via (e.g., the first conductive via  623  in  FIG. 9 ) from the second conductive via (e.g., the second conductive via  624  in  FIG. 9 ) disposed at a position overlapping with the center (e.g., the center C in  FIG. 9 ) of the conductive patch (e.g., the conductive patch  510  in  FIG. 9 ) toward the edge portion increases gradually. For example, when the first conductive via  623  is positioned at about a 30% point (e.g., a 28% point) where the separation distance D 1  is about 0.4 mm from the second conductive via (e.g., the center C of the conductive patch  510 ), it was found that the gain decreased by about 1 dB. Also, when the separation distance (D 1 ) is changed to about 0.6 mm corresponding to about a 50% point (e.g., a 42% point), it was found that the gain decreased by more than 2 dB. From this result, it can be seen that, when the first conductive via  623  and/or the second conductive via  624  are positioned based on the center C within about 30% of the linear distance D from the center C to the edge portion of the conductive patch  510 , the antenna structure  500  can be used without significant performance degradation. However, in case of being disposed at the separation distance D 1  that is farther than the above from the center C, it may be difficult to use due to deterioration in performance. 
       FIG. 11  is a diagram illustrating the arrangement structure of conductive pads included in an electronic component according to an embodiment of the disclosure. 
     Referring to  FIG. 11 , the key module  620  may include a surface mount device (SMD) pad  625  disposed between the first substrate surface (e.g., the first substrate surface  5901  in  FIG. 6A ) of the substrate (e.g., the substrate  590  in  FIG. 6A ) and the button substrate  621 . According to an embodiment, the SMD pad  625  may include a conductive pad  6251  for electrical connection to the first conductive via  623  (e.g., a signal via) exposed to the first substrate surface (e.g., first substrate surface  5901  in  FIG. 6A ) of the substrate (e.g., the substrate  590  in  FIG. 6A ), and a connection part  6252  for electrical connection to the second conductive via  624  (e.g., a ground via). According to an embodiment, the conductive pad  6251  and the connection part  6252  may be selectively electrically connected to each other through the conductive contact (e.g., the conductive contact  622  in  FIG. 6A ) of the key button device (e.g., the key button device  600  in  FIG. 6A ). According to an embodiment, the conductive pad  6251  and the connection part  6252  are disposed at positions overlapping with the first conductive via  623  and the second conductive via  624  exposed on the first substrate surface  5901  when the substrate  590  is viewed from above, so that they can be electrically connected to each other merely by an operation in which the key module  620  is mounted on the first substrate surface  5901 . According to an embodiment, the conductive pad  6251  and the connection part  6252  may be electrically connected to the first conductive via  623  and the second conductive via  624 , respectively, through at least one of soldering, conductive taping, conductive bonding, and/or electrical connection member (e.g., conductive contact spring). 
     According to various embodiments, depending on the arrangement position of the key button  610  and/or a design of the key module  620  (e.g., the arrangement position of the conductive contact  622 ), the conductive pad  6251  may be eccentrically disposed to have a certain separation distance from the center C of the conductive patch (e.g., the conductive patch  510  in  FIG. 6A ) rather than corresponds to the first conductive via  623 . In this case, the conductive pad  6251  is formed to have an elongated shape, so that the conductive contact (e.g., the conductive contact  622  in  FIG. 6A ) of the key module may be electrically connected at a first point P 1  of the conductive pad  6251 , and the first conductive via  623  may be electrically connected at a second point P 2  of the conductive pad  6251  closer to the center C of the conductive patch  510  than the first point P 1 . Accordingly, by forming the conductive pad  6251  to have an elongated shape and allowing the first conductive via  623  closer to the center C, it is possible to reduce the deterioration in radiation performance of the antenna structure (e.g., the antenna structure  500  in  FIG. 6A ). In some embodiments, the connection pad  6251  may also be electrically connected to the second conductive via  624  in substantially the same manner. In some embodiments, the conductive pad  6251  and the connection part  6252  of the SMD pad  625  may be formed directly on the button substrate (e.g., the button substrate  621  in  FIG. 6A ). In some embodiments, the SMD pad  625  including the conductive pad  6251  and the connection part  6252  may be replaced with the dummy patch  5111  in  FIG. 6C .

     Referring to  FIG. 12A , an antenna structure  700  may include the substrate  590  and also include, as a plurality of antenna elements arranged side by side at a specified interval on the substrate  590 , a first conductive patch  710 , a second conductive patch  720 , a third conductive patch  730 , and/or a fourth conductive patch  740 .

According to an embodiment, the first key module  620  may be disposed at a position overlapping with the first conductive patch  710  when the substrate  590  is viewed from above. According to an embodiment, the second key module  630  may be disposed at a position overlapping with the fourth conductive patch  740  when the substrate  590  is viewed from above.

     In describing the antenna structure  700  and the key button device  600  shown in  FIG. 12B , the same reference numerals are assigned to substantially the same components as those of the antenna structure  700  and the key button device  600  shown in  FIG. 12A , and a detailed description may be omitted. 
     Referring to  FIG. 12B , the first key module  620  of the key button device  600  may be disposed at a position overlapping with the first conductive patch  710  when the substrate  590  is viewed from above. According to an embodiment, the second key module  630  of the key button device  600  may be disposed to overlap with a space between the third conductive patch  730  and the fourth conductive patch  740  when the substrate  590  is viewed from above. This arrangement structure may be determined depending on the size of the key button  610  of the key button device  600  and/or the arrangement positions of the pressing protrusions (e.g., the pressing protrusions  611  and  612  in  FIG. 5A ) formed on the key button  610 . 
     In describing the key button device  600  shown in  FIG. 12C , the same reference numerals are assigned to substantially the same components as those of the key button device  600  shown in  FIG. 12A , and a detailed description may be omitted. 
     Referring to  FIG. 12C , an antenna structure  750  may include the substrate  590  and also include, as a plurality of antenna elements disposed on the substrate  590 , and a first conductive patch  751 , a second conductive patch  752  disposed side by side with the first conductive patch  751  in a second direction (direction {circle around ( 2 )}), a third conductive patch  753  disposed side by side with the first conductive patch  751  in a third direction (direction {circle around ( 3 )}) perpendicular to the second direction (direction {circle around ( 2 )}), and a fourth conductive patch  754  disposed side by side with the second conductive patch  752  in the third direction (direction {circle around ( 3 )}). According to an embodiment, the fourth conductive patch  754  may be disposed side by side with the third conductive patch  753  in the second direction (direction {circle around ( 2 )}). For example, the antenna structure  750  may operate as an array antenna having a 2×2 structure. 
     According to various embodiments, the key button device  600  may include the first key module  620  disposed at a position overlapping with the first conductive patch  751  and the second key module  630  disposed at a position overlapping with the third conductive patch  753  when the substrate  590  is viewed from above. According to an embodiment, when the substrate  590  is viewed from above, the key button  610  may be disposed at a position that overlaps at least in part with the first and third conductive patches  751  and  753 . In another embodiment, the first key module  620  and/or the second key module  630  may be disposed at a position overlapping with the second conductive patch  752  and/or the third conductive patch  753  when the substrate  590  is viewed from above. In this case, the arrangement position and/or shape of the key button  610  may be changed. In some embodiments, the key button device  600  may have two key buttons arranged to be manipulatable through the two key modules  620  and  630 . 
     Although each of the antenna structure  700  and  750  shown in  FIGS. 12A to 12C  include the two key modules  620  and  630 , this is not construed as a limitation. For example, each of the antenna structure  700  and  750  may include one key module or three or more key modules disposed on the substrate  590 . 
       FIG. 13  is a diagram illustrating the configuration of an antenna structure including a key button device according to an embodiment of the disclosure. 
     Referring to  FIG. 13 , an antenna structure  800  may include the substrate  590  and also include, as a plurality of antenna elements arranged side by side at a predetermined interval on the substrate  590 , a first conductive patch  810 , a second conductive patch  820 , a third conductive patch  830 , a fourth conductive patch  840 , and/or a fifth conductive patch  850 . According to an embodiment, although not shown, each of the conductive patches  810 ,  820 ,  830 ,  840 , and  850  may have the power feed structure of  FIG. 7C  (a dual-polarization feed structure). In some embodiments, each of the conductive patches  810 ,  820 ,  830 ,  840 , and  850  may be replaced with the power feed structure of  FIG. 7A  (a single feed structure) or the power feed structure of  FIG. 7D  (a dual-feed dual-polarization feeding structure). For example, the antenna structure  800  may operate as an array antenna having a 1×5 structure. 
     According to various embodiments, the key button device  600  may be disposed at a position that overlaps at least in part with the substrate  590  when the substrate  590  is viewed from above. According to an embodiment, the key button device  600  may include the key button  610  and also include, to generate key input signals through manipulation of the key button  610 , the first key module  620  having the first button substrate  621  and the first conductive contact  622  and the second key module  630  having the second button substrate  631  and the second conductive contact  632 . According to an embodiment, the first key module  620  may be disposed at a position overlapping with the first conductive patch  810  when the substrate  590  is viewed from above. According to an embodiment, the second key module  630  may be disposed at a position overlapping with the fourth conductive patch  840  when the substrate  590  is viewed from above. In some embodiments, the key modules  620  and  630  may be symmetrically disposed with respect to the third conductive patch  830 . For example, based on the third conductive patch  830 , the first key module  620  may be disposed on the second conductive patch  820 , and the second key module  630  may be disposed on the fourth conductive patch  840 . In another example, based on the third conductive patch  830 , the first key module  620  may be disposed on the first conductive patch  810 , and the second key module  630  may be disposed on the fifth conductive patch  850 . In some embodiments, the key modules  620  and  630  may be asymmetrically disposed on any two conductive patches of the conductive patches  810 ,  820 ,  830 ,  840 , and  850 . In some embodiments, the key button device  600  may have two key buttons arranged to be manipulatable through the two key modules  620  and  630 . 
       FIG. 14  is a graph illustrating the radiation performance of an antenna structure depending on the presence or absence of a key button device in the configuration of  FIG. 13  according to an embodiment of the disclosure. 
     Referring to  FIG. 14 , it can be seen that, in the antenna structure  800  of  FIG. 13  supporting dual polarization and including the conductive patches (e.g., the conductive patches  810 ,  820 ,  830 ,  840 , and  850  in  FIG. 13 ) with a 1×5 array structure, the gains of vertical polarization (graph  1401 ) and horizontal polarization (graph  1402 ) when the key modules (e.g., the key modules  620  and  630  in  FIG. 13 ) of the key button device (e.g., the key button device  600  in  FIG. 13 ) are disposed to overlap with some conductive patches  810  and  840  among the conductive patches  810 ,  820 ,  830 ,  840 , and  850  do not change significantly enough to affect the radiation performance in an operating frequency band  1410  (e.g., about 28 GHz) compared to the gains of vertical polarization (graph  1403 ) and horizontal polarization (graph  1404 ) when the key button device  600  is not disposed. This means that, even if the conductive patches  810 ,  820 ,  830 ,  840 , and  850  have an array arrangement structure and the key modules  620  and  630  are disposed to overlap with some conductive patches  810  and  840  among the conductive patches  810 ,  820 ,  830 ,  840 , and  850 , the radiation performance of the antenna structure  800  is not substantially deteriorated. 
       FIG. 15  is a diagram illustrating the configuration of an antenna structure including key modules according to an embodiment of the disclosure. 
     In describing the antenna structure  800  shown in  FIG. 15 , the same reference numerals are assigned to substantially the same components as those of the antenna structure  800  shown in  FIG. 13 , and a detailed description may be omitted. 
     Referring to  FIG. 15 , the first key module  620  may be disposed at a position overlapping at least in part with the first conductive patch  810  when the substrate  590  is viewed from above. According to an embodiment, while such a partial overlap with the first conductive patch  810  is maintained, the center of the first key module  620  may be shifted from the center of the first conductive patch  810  rightwards by a first distance t 1  along a second direction (direction {circle around ( 2 )}) parallel to a long side  590   a  of the substrate  590  and downwards by a second distance t 2  along a third direction (direction {circle around ( 3 )}) parallel to a short side  590   b  of the substrate  590 . According to an embodiment, while a partial overlap with the fifth conductive patch  850  is maintained, the center of the second key module  630  may be shifted from the center of the fifth conductive patch  850  leftwards by the first distance t 1  along the second direction (direction {circle around ( 2 )}) parallel to the long side  590   a  of the substrate  590  and downwards by the second distance t 2  along the third direction (direction {circle around ( 3 )}) parallel to the short side  590   b  of the substrate  590 . In this case, each of the first and second key modules  620  and  630  may be changed in shape to have the conductive pad  6251  as shown in  FIG. 11 , and the first conductive via (e.g., the first conductive via  623  in  FIG. 11 ) of the substrate  590  may be formed to be electrically connected at a position close to the center of the conductive patch  810  or  850 . 
       FIGS. 16A and 16B  are graphs illustrating the radiation performance of an antenna structure depending on the movement arrangement of key modules in the configuration of  FIG. 15  according to various embodiments of the disclosure. 
     Referring to  FIGS. 16A and 16B , graphs show the gains of horizontal polarization and vertical polarization of the antenna structure  800  when each of the first and second key modules  620  and  630  is disposed at the center of each of the first and fifth conductive patches  810  and  850 , when shifted from the center by the first shift distance t 1  (e.g., about 6 mm) along the second direction (direction {circle around ( 2 )}) parallel to the long side  590   a  of the substrate  590 , when shifted from the center by the second shift distance t 2  (e.g., about 6 mm) along the third direction ({circle around ( 3 )} direction) parallel to the short side  590   b  of the substrate  590 , or when shifted by both the first shift distance t 1  and the second shift distance t 2 , in the configuration of  FIG. 15 , when the substrate  590  is viewed from above. It can be seen that the gain change is not large enough to affect the radiation performance in an operating frequency band  1601  or  1602  (e.g., about 28 GHz). This means that, even if the key modules  620  and  630  are eccentrically disposed while overlapping at least in part with the conductive patches  810  and  850 , the radiation performance of the antenna structure  800  is not substantially deteriorated. 
       FIG. 17  is a diagram illustrating the configuration of an antenna structure including key modules according to an embodiment of the disclosure. 
     Referring to  FIG. 17 , an electronic device (e.g., the electronic device  300  in  FIG. 5A ) may include an antenna structure  1700  including the substrate  590  and a plurality of conductive patches  1710 ,  1720 ,  1730 , and  1740  disposed on the substrate  590 , and the key button device  600  including the first key module  620  and/or the second key module  630  disposed to overlap with some conductive patches  1710  and  1740  among the conductive patches  1710 ,  1720 ,  1730 , and  1740  when the substrate  590  is viewed from above. According to an embodiment, the antenna structure  1700  may include an electrical connection member  597  which extends from the substrate  590  and on which a wireless communication circuit  598  (e.g., the wireless communication circuit  595  in  FIG. 6A ) (e.g., RFIC) is disposed. According to an embodiment, the electrical connection member  597  may include a flexible printed circuit board (FPCB) type RF cable (FRC) or a coaxial cable. 
     According to various embodiments, the electrical connection member  597  may be electrically connected to the main board (e.g., the printed circuit board  340  in  FIG. 3C ) of the electronic device (e.g., the electronic device  300  in  FIG. 5A ) through a connector (not shown). Accordingly, the antenna structure  1700  may be electrically connected to the main board (e.g., the printed circuit board  340  in  FIG. 3C ) through the electrical connection member  597 . In some embodiments, the wireless communication circuit  598  may be disposed on the main board (e.g., the printed circuit board  340  in  FIG. 3C ). According to an embodiment, the key button device  600  may be disposed on the substrate  590  and electrically connected to the electrical connection member  597  through an electrical connection structure including a conductive via (e.g., the first conductive via  623  in  FIG. 6A ) connected to the key modules  620  and  630 . 
       FIG. 18A  is a partially cutaway perspective view illustrating an electronic device in which a key button device is disposed in a housing according to an embodiment of the disclosure. 
       FIG. 18B  is a cross-sectional view partially illustrating the electronic device taken along line  18   b - 18   b  of  FIG. 18A  according to an embodiment of the disclosure. 
     Referring to  FIGS. 18A and 18B , the electronic device  300  may include the housing  310  including the side member  320 , the antenna structure  500  disposed in the inner space of the housing  310  to form a beam pattern in a first direction (direction  0 ) toward which the side member  320  faces, and the key button device  600  that faces at least in part the antenna structure  500  and is disposed to be at least partially visible from the outside and be manipulatable through the side member  320 . According to an embodiment, when the side member  320  is viewed from the outside, at least a portion of the key button device  600  may be disposed to overlap with the antenna structure  500 . 
     According to various embodiments, the key button device  600  may include the key button  610  at least partially protruded or exposed to the outside through the opening  321  formed in the side member  320 , and the first key module  620  or the second key module  630  disposed between the key button  610  and the substrate  590  of the antenna structure  500 . According to an embodiment, the first key module  620  may include the first button substrate  621  disposed on the substrate  590  and the first conductive contact  622  disposed on the first button substrate  621 . The second key module  630  may include the second button substrate  631  and the second conductive contact  632 . 
     According to various embodiments, the side member  320  may include a conductive material  320   a  of the electronic device  300 . According to an embodiment, the side member  320  may include a non-conductive material  320   b  insert-injected into the conductive material  320   a.  According to an embodiment, the opening  321  may be formed in the conductive material  320   a.  In this case, the antenna structure  500  may be disposed such that a beam pattern is formed through the opening  321  in the first direction (direction {circle around ( 1 )}) toward which the key button  610  disposed to overlap with the substrate  590  faces. To allow smooth formation of the beam pattern, the key button  610  may be formed of a non-conductive material (e.g., injection material). 
       FIGS. 19A to 19E  are diagrams illustrating the configuration of a key button or a housing for radiation of an antenna structure according to various embodiments of the disclosure. 
     Referring to  FIG. 19A , the key button device  600  may include the key button  610  including a pair of pressing protrusions  611  and  612 , and the key modules  620  and  630  disposed respectively at positions corresponding to the pair of pressing protrusions  611  and  612 . According to an embodiment, the key modules  620  and  630  may be disposed on the substrate  590  of the antenna structure  500  as described above. 
     According to various embodiments, the antenna structure  500  may be disposed such that a beam pattern is formed in the first direction (direction {circle around ( 1 )}) toward which the key button  610  faces. In this case, the key button  610  disposed to overlap at least in part with the direction of the beam pattern may have the conductive material  610   a  (e.g., metal) and/or the non-conductive material  610   b  (e.g., polymer). For example, the key button  610  may be formed of at least partially segmented conductive material  610   a  through insert injection of the non-conductive material  610   b.  According to an embodiment, in the key button  610 , the non-conductive material  610   b  may be disposed between (e.g., in a middle of) the pair of pressing protrusions  611  and  612 . 
     Referring to  FIG. 19B , because the key button  610  includes the pressing protrusions  611  and  612  formed of the non-conductive material  610   b  in the configuration of  FIG. 19A , it can reduce interference when the antenna structure  500  forms a beam pattern. 
     Referring to  FIG. 19C , the key button  610  may be exposed or protruded from the opening  321  of the side member  320  to be visible from the outside. According to an embodiment, in the exposed portion when the side member  320  is viewed from the outside, the key button may be formed of the conductive material  610   a  disposed centrally and the non-conductive material  610   b  surrounding at least a portion of the edge of the conductive material  610   a.  For example, the non-conductive material  610   b  may be disposed in a closed loop shape along the edge of the conductive material  610   a  or alternatively in an open loop shape in which the conductive material  610   a  is at least partially interposed. 
     Referring to  FIG. 19D , the opening  321  may have the conductive material  320   a  or the non-conductive material  320   b  of the side member  320 . In this case, the non-conductive material  320   b  may be exposed to the outside through the opening  321  or disposed at a position facing the key button  610  protruded. For example, the non-conductive material  320   b  may form the entire inner rim of the opening  321  or may form a partial inner rim of the opening  321  through the intervention of the conductive material  320   a.    
     Referring to  FIG. 19E , when the opening  321  is viewed from the outside, the key button  610  of the key button device  600  may be disposed to overlap at least in part with the first and second key modules  620  and  630  disposed on the antenna structure  500 . According to an embodiment, the key button  610  may be formed of a conductive material. In this case, the key button  610  may be formed to have a second width TH 2  smaller than a first width TH 1  of the opening  321 . Accordingly, the beam pattern formed by the antenna structure  500  may be transmitted to the outside through a space between the opening  321  and the key button  610 . 
     In some embodiments, when the first width TH 1  and the second width TH 2  are formed to be substantially the same, the beam pattern of the antenna structure  500  may be transmitted to the outside through a non-conductive portion formed in the side member (e.g., the side member  320  in  FIG. 19D ) near the key button  610 .
