Description:
CROSS REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation application, claiming priority under § 365(c), of an International application No. PCT/KR2021/018673, filed on Dec. 9, 2021, which is based on and claims the benefit of a Korean patent application number 10-2020-01887778, filed on Dec. 31, 2020, in the Korean Intellectual Property Office, the disclosures of which is incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     Certain embodiments of the disclosure relate to an antenna and an electronic device including the same. 
     BACKGROUND ART 
     Electronic devices (for example, electronics device for communication) are widely used in daily life with the development of wireless communication technologies. Network are gradually reaching capacity limits as a result abrupt increases in bandwidth use. In order to satisfy wireless data traffic demands that have been increasing since commercialization of 4G (4 th  generation) communication systems, there has been research regarding a communication system (for example, 5G (5 th  generation), pre-5G communication system, or new radio (NR)) that transmits and/or receives signals by using a high-frequency (for example, mmWave) band (for example, 3 GHz-300 GHz band). 
     The next-generation wireless communication technology can transmit and receive wireless signals using a frequency substantially in the range of about 3 GHz to 100 GHz. An efficient mounting structure and a new antenna structure (e.g., an antenna module) corresponding thereto can overcome high free-space loss due to frequency characteristics and to increase the gain of an antenna. The antenna structure may include an array antenna in which a variable number of antenna elements (e.g., conductive patches and/or conductive patterns) are arranged at regular intervals. These antenna elements may be arranged such that a beam pattern is formed in any one direction inside the electronic device. For example, the antenna structure may be arranged such that a beam pattern is formed toward at least a portion of the front surface, the rear surface, and/or the side surface in the inner space of the electronic device. 
     The electronic device may include a conductive portion (e.g., a metal member) arranged on at least a portion of the housing and a non-conductive portion (e.g., a polymer member) coupled to the conductive portion to reinforce rigidity and form a beautiful appearance. The conductive portion may be at least partially omitted in a portion facing the antenna structure arranged in the inner space of the electronic device, and the omitted portion may be replaced with a non-conductive portion. 
     However, eddy current (e.g., trap current) may be generated in a conductive portion located near the antenna structure and forming a boundary region by being coupled to the non-conductive portion. Eddy currents can include loops of electrical current induced within conductors by a changing magnetic field in the conductor. As a result, the radiation performance of the antenna structure may be deteriorated. In order to solve this problem, the non-conductive portion coupled to the conductive part may extend to a position relatively far from the antenna structure, but this may cause a decrease in rigidity of the electronic device. 
     SUMMARY 
     Certain embodiments of the disclosure are able to provide an antenna configured to suppress radiation performance degradation through a support structure of an antenna structure and an electronic device including the same. 
     According to certain embodiments, it is possible to provide an antenna and an electronic device including the same, wherein the antenna can be capable of suppressing radiation performance degradation even when a conductive portion is arranged in the vicinity of an antenna structure. This is helpful for reinforcing rigidity of the electronic device. 
     According to an embodiment of this disclosure, an electronic device comprises: a housing including a non-conductive portion; an antenna structure arranged in the housing, wherein the antenna structure includes: a substrate including a first substrate surface facing a first direction and a second substrate surface facing opposite the first substrate surface; and at least one antenna element arranged on the substrate to form a beam pattern in the first direction; a conductive member including a plurality of first slits arranged in an inner space of the housing to at least partially face the second substrate surface and formed at a position where the plurality of first slits at least partially overlap the at least one antenna element when the first substrate surface is viewed from above; and a wireless communication circuit configured to transmit or receive a wireless signal in a predetermined frequency band through the at least one antenna element, wherein the at least one antenna element is arranged to at least partially overlap the non-conductive portion when the housing is viewed from outside. 
     According to another embodiments, as electronic device comprises: a housing including a conductive portion forming at least a portion of a side surface, and a remaining portion; a wireless communication circuit arranged in an inner space of the housing; and an antenna structure arranged in the inner space, wherein the antenna structure includes: a substrate; and an antenna structure including at least one antenna element arranged on a substrate surface; a conductive member including a plurality of slits arranged in an inner space of the housing to at least partially face the opposite substrate surface and formed at a position at which the slits at least partially overlap the at least one antenna element when the substrate surface is viewed from above; and a wireless communication circuit configured to transmit or receive a wireless signal in a predetermined frequency band through the at least one antenna element, wherein the antenna structure is arranged at a position at which the remaining portion fully overlaps the antenna structure when the side surface is viewed from outside, and wherein the at least one antenna element is configured to form a beam in a direction towards the remaining portion. 
     The antenna structure according to an embodiment of the disclosure can have a plurality of slits formed in the conductive member supporting the substrate so that radiation performance degradation of an antenna can be suppressed by reducing or eliminating eddy current generated in a boundary region between the conductive portion and the non-conductive portion of the housing. In addition, since the conductive portion of the housing can be arranged up to the vicinity of the antenna structure through the plurality of slits formed in the conductive member supporting the substrate, the antenna structure can be helpful for reinforcing the rigidity of the electronic device. 
     In addition, various effects directly or indirectly identified through this document may be provided.

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 Above  6 RF signal. Upon reception, the 5G Above 6RF 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 conductive patches  510 ,  520 ,  530 , and  540  may have substantially the same shape. Although the antenna structure  500  according to exemplary embodiments of the disclosure has been illustrated and described with reference to an array antenna AR including four conductive patches  510 ,  520 ,  530 , and  540 , the disclosure is not limited thereto. For example, the antenna structure  500  may include one single conductive patch, or may include two or five or more conductive patches, as an array antenna (AR). In some embodiments, the antenna structure  500  may further include a plurality of conductive patterns (e.g., a dipole antenna) arranged on the substrate  590 . In this case, the conductive patterns may be arranged such that a beam pattern is formed in a direction (e.g., a vertical direction) different from the direction of the beam pattern of the conductive patches  510 ,  520 ,  530 , and  540 .

The conductive shield layer  594  may block a noise (e.g., a DC-DC noise or an interference frequency component) generated in the antenna structure  500  from spreading to the surroundings. The conductive shield layer  594  may include a conductive material applied to the surface of the protection member  593  through a thin film deposition method such as sputtering. The conductive shield layer  594  may be electrically connected to a ground of the substrate  590 .

     Referring to  FIG. 6 , an electronic device (e.g., the electronic device  700  of  FIG. 7B ) may include a conductive member  550 . The conductive member  550  can be fixed to a conductive portion (e.g., the conductive portion  721  in  FIG. 7B ) of a housing (e.g., the housing  710  in  FIG. 7B ). An antenna structure  500  can be arranged to be at least partially supported via the conductive member  550 . The conductive member  550  may be fixed to a conductive portion (e.g., the conductive portion  721  in  FIG. 7B ) of a support member (e.g., the support member  711  in  FIG. 7B ) formed as a portion of the housing (e.g., the housing  710  in  FIG. 7B ). The conductive member  550  may be helpful for reinforcing the rigidity of the antenna structure  500  by being at least partially in contact with the conductive portion (e.g., the conductive portion  721  in  FIG. 7B ) of the side member (e.g., the side member  720  in  FIG. 7B ) and may effectively diffuse heat by transferring heat generated from the antenna structure  500  to the conductive portion  721  of the housing  710 . Accordingly, the conductive member  550  may be formed of a metal material (e.g., SUS, Cu, or Al) having suitable thermal conductivity and tensile strength or in excess of a threshold. 
     According to certain embodiments, the conductive member  550  may include a conductive plate  551  made of a metal and at least one extension  5521  or  5522 . The at least one extension  5521  or  5522  can extend outward from the conductive plate  551  and are configured to be fixed to the conductive portion (e.g., the conductive portion  721  in  FIG. 7B ) of the housing (e.g., the housing  710  of  FIG. 7B ). The conductive plate  551  may include support positions.

     The conductive plate  551  may further include a fifth support portion (not illustrated) extending from the first support portion  5511  and correspondingly arranged to cover the third substrate side-surface  5903   c.  The at least one extension  5521  or  5522  may include a first extension  5521  extending outward from the third support portion  5513  and a second extension  5522  extending outward from the fourth support portion  5514 . The first extension  5521  and the second extension  5522  may be fixed to the conductive portion (e.g., conductive portion  721  in  FIG. 7B ) of the housing (e.g., the housing  710  in  FIG. 7B ) via fastening members such as screws (e.g., the screws S in  FIG. 7C ). 
     The conductive member  550  may include a plurality of first slits  560  (e.g., a plurality of first openings) formed in the first support portion  5511  corresponding to the second substrate surface  5902  of the substrate. Each one of the plurality of first slits  560  may be formed through a plurality of unit slits  5611  having a predetermined interval and length. 
     The plurality of first slits  560  may include first sub-slits  561  (e.g., a first pattern) formed at a position at which the first sub-slits  561  at least partially overlap the first conductive patch  510  when the first substrate surface  5901  is viewed from above, second sub-slits  562  (e.g., a second pattern) formed at a position at which the second sub-slits  562  at least partially overlap the second conductive patch  520  when the first substrate surface  5901  is viewed from above, third sub-slits  563  (e.g., a third pattern) formed at a position at which the third sub-slits  563  at least partially overlap the third conductive patch  530  when the first substrate surface  5901  is viewed from above, and fourth sub-slits  564  (e.g., a fourth pattern) formed at a position at which the fourth sub-slits  564  at least partially overlap the fourth conductive patch  540  when the first substrate surface  5901  is viewed from above. According to an embodiment, the first sub-slits  561 , the second sub-slits  562 , the third sub-slits  563 , and the fourth sub-slits  564  may be arranged in groups at corresponding positions overlapping the conductive patches  510 ,  520 ,  530 , and  540 , respectively, through a plurality unit slits  5611  having a predetermined interval and length. 
     The antenna structure  500  may be arranged to form a beam pattern through a non-conductive portion (e.g., the non-conductive portion  722  in  FIG. 7B ) in the inner space (e.g., the inner space  7001  in  FIG. 7B ) of the electronic device (e.g., the housing  710  in  FIG. 7B ), and the non-conductive portion  722  may be coupled to a conductive portion  721 . Accordingly, the housing  710  may include a boundary region between the conductive portion  721  and the non-conductive portion  722  near the region in which the antenna structure  500  is arranged, and some of the current applied to the antenna structure  500  (e.g., leakage current) may be excited (leaked) into the conductive portion of the boundary region. The foregoing acts as an eddy current (e.g. trap current). Eddy currents can degrade radiating performance. 
     The plurality of conductive first slits  560  may be helpful for reducing eddy currents This improves radiation performance of the antenna structure by making the path of eddy currents, which are out-of phase have a phase difference and inducing the phase, close to be in-phase. In some embodiments, the conductive member  550  may be arranged in the vicinity of the antenna structure  550  to be at least partially in contact with or proximate to the substrate  590  and may be replaced with a portion of a conductive support member  711  or a conductive bracket (not illustrated) including a plurality of slits  5611 . In some embodiments, the conductive member  550  may be arranged on the opposite substrate surface  5902  of the substrate  590 , and may be replaced with a conductive shield member  594  including a plurality of slits  5611 . 
     Hereinafter, an arrangement relationship for the plurality of conductive slits  560  will be described in detail. 
     The antenna structure  500  and conductive member  550  can be pressed up against a side member  720  of the housing  710 . The side member  720  can include a non-conductive portion  722  and conductive portion  721 . The first substrate surface  5901  and the conductive patches  510 - 540  can make contact with an inner surface of the non-conductive portion  722 . The conductive patches  510 - 540  can form a beam pattern through the non-conductive portion  722  of the side member  720 . The conductive member  550  faces the opposite direction. The conductive member  550  may support the antenna structure  500  and face the inside of the electronic device. The plurality of first slits  560  may face the inside of the electronic device. 
     Although the antenna structure  500  is in the vicinity of the conductive portion  721 , induced eddy currents are reduced. The plurality of first slits  560  may be formed to have a length in a direction perpendicular to a polarization direction in at least a portion of the conductive member  550 . This causes the eddy currents that are induced in the conductive portion  721  to be close to in-phase, thereby reducing degradation in performance.

The antenna structure  500  may be arranged to face the side member  720  through the conductive member  550  arranged on a module mounting portion  7201  provided via the side member  720  and/or the side portion  720  and at least a portion of the support member  711 . The antenna structure  500  may be arranged substantially perpendicular to the front plate  730  such that the first substrate surface  5901  of the substrate  590  corresponds to the side member  720  and may be configured such that a beam pattern is formed in the first direction (direction {circle around (1)}), the space between the side member  720  and the front plate  730 , the direction in which the front plate  730  is oriented, the space between the side member  720  and the rear plate  740 , and/or the direction in which the rear plate  740  is oriented.

When the substrate  590  is arranged in the inner space of the housing  710 , at least a portion of the substrate  590  (e.g., the cross section  591  and/or the edge portion of the long side  592  of the substrate  590 ) may be arranged to overlap the conductive portion  721  when the side member  720  is viewed from the outside. In some embodiments, all of the substrate  590  may be arranged not to overlap the conductive portion  721 . That is, a remaining portion of the side member  720  that does not include the conductive portion  721  may fully overlap the substrate  590 . When the substrate  590  is arranged in the inner space of the housing  710 , the first conductive patch  510 , the second conductive patch  520 , the third conductive patch  530 , and the fourth conductive patch  540  may be arranged at a position that does not overlap the conductive portion  721  when the side member  720  is viewed from the outside.

The antenna structure  500  may include a third feeding portion  521  and a fourth feeding portion  522  arranged on the second conductive patch  520  in substantially the same manner as the arrangement structure of the first feeding portion  511  and the second feeding portion  512  arranged on the first conductive patch  510 . The antenna structure  500  may include a fifth feeding portion  531  and a sixth feeding portion  532  arranged on the third conductive patch  530  in substantially the same manner as the arrangement structure of the first feeding portion  511  and the second feeding portion  512  arranged on the first conductive patch  510 . The antenna structure  500  may include a seventh feeding portion  541  and an eighth feeding portion  542  arranged on the fourth conductive patch  540  in substantially the same manner as the arrangement structure of the first feeding portion  511  and the second feeding portion  512  arranged on the first conductive patch  510 . Accordingly, the antenna structure  500  may be operated as an array antenna AR via the first conductive patch  510 , the second conductive patch  520 , the third conductive patch  530 , and the fourth conductive patch  540 . For example, the wireless communication circuit (e.g., the wireless communication circuit  595  in  FIG. 5B ) may be configured such that a first polarized wave operating in a third direction (direction {circle around (3)}) parallel to the short sides  591  of the substrate is formed via the first feeding portion  511 , the third feeding portion  521 , the fifth feeding  531 , and the seventh feeding portion  541 , and may be configured such that a second polarized wave perpendicular to the first polarized wave is formed in a fourth direction (direction {circle around (4)}) parallel to the long sides  592  of the substrate via the second feeding portion  512 , the fourth feeding portion  522 , the sixth feeding portion  532 , and the eighth feeding portion  542 . The wireless communication circuit (e.g., the wireless communication circuit  595  in  FIG. 5B ) may be configured to transmit and/or receive a wireless signal in a frequency band in the range from about 3 GHz to about 300 GHz via the array antenna AR. 
     According to certain embodiments, the conductive member  550  may include a plurality of first conductive slits  560  arranged on a first support portion  5511  corresponding to the second substrate surface  5902 . The plurality of first conductive slits  560  may include, in the first support portion  5511 , first sub-slits  561  (e.g., a first pattern) arranged at a position at which the first sub-slits  561  at least partially overlap the first conductive patch  510  when the first substrate surface  5901  is viewed from above (when the side member  720  is viewed from the outside), second sub-slits  562  (e.g., a second pattern) arranged at a position at which the second sub-slits  562  at least partially overlap the second conductive patch  520  when the first substrate surface  5901  is viewed from above, third sub-slits  563  (e.g., a third pattern) arranged at a position which the third sub-slits  563  at least partially overlap the third conductive patch  530  when the first substrate surface  5901  is viewed from above, and fourth sub-slits  564  (e.g., a fourth pattern) arranged at a position at which the fourth sub-slits  564  at least partially overlap the fourth conductive patch  540  when the first substrate surface  5901  is viewed from above. The plurality of first conductive slits  560  may be formed to have a length in a direction (e.g., direction {circle around (4)}) perpendicular to the vertical polarization direction (e.g., direction {circle around (3)}) of the above-described two polarized waves. 
     The antenna structure  500  according to an exemplary embodiment of the disclosure may be helpful for suppressing radiation performance degradation of the array antenna AR by reducing eddy current generated by the a peripheral conductive portion  721  of the housing  710  by inducing the eddy current to be close to in-phase via the plurality of conductive slits  560  formed to have a length in a direction perpendicular to a polarization direction (e.g., a vertical polarization direction) in at least a partial region of the conductive member  550  supporting the substrate  590 . 
       FIGS. 8A and 8B  are views illustrating, in a comparative manner, a current distribution excited in a conductive member when a plurality of slits according to certain embodiments of the disclosure are present and a current distribution when the plurality of slits are absent, respectively. 
       FIG. 8A  is a view illustrating an eddy current distribution around an antenna structure  500  supported via a conductive member  550  in which the plurality of first conductive slits  560  are not formed, and  FIG. 8B  a view illustrating an eddy current distribution around the antenna structure  500  supported via the conductive member  550  in which the plurality of first conductive slits  560  are formed according to an exemplary embodiment. 
     Referring to  FIGS. 8A and 8B , it can be seen that, when the antenna structure  500  operates in a predetermined frequency band (e.g., n261 band (27.5 GHz to 28.35 GHz)), the eddy current is reduced in the region of the portion  8101  in which the plurality of conductive slits  560  are formed. This means that the conductive portion  721  may be helpful for reducing the radiation performance degradation of the antenna structure  500  since the eddy current formed around the antenna structure  500  is reduced via the first plurality of conductive slits  560 . 
     According to certain embodiments, as illustrated in Table 1 below, in a 50% section of a cumulative distribution function (CDF), it can be seen that a gain of 4.7 dB is exhibited in the case of  FIG. 8A , whereas a gain of 5 dB is exhibited in the case of  FIG. 8B , whereby the gain is substantially improved by 0.3 dB.

       FIG. 9A and 9B  shows a configuration of the conductive patches  910 ,  920 ,  930 ,  940  that are rotated  45  degrees as compared to the configuration in  FIG. 5A . Similarly, the plurality of first conductive slits are also rotated 45 degrees. Additionally, the feeding portions of are along lines L 3  and L 4 . 
       FIG. 9A  is a view illustrating a configuration of an antenna structure according to certain embodiments of the disclosure.  FIG. 9B  is a view illustrating a partial configuration of a conductive member supporting the antenna structure of  FIG. 9A  according to certain embodiments of the disclosure. 
     The antenna structure  900  of  FIG. 9A  may be at least partially similar to the third antenna module  246  of  FIG. 2 , or may further include other embodiments of the antenna structure. In some embodiments, the antenna structure  500  arranged in the electronic device  700  of  FIG. 7C  may be replaced with the antenna structure  900  of  FIG. 9A . 
     Referring to  FIGS. 9A and 9B , the antenna structure  900  may include a substrate  590  and a plurality of conductive patches  910 ,  920 ,  930 , and  940 , as an array antenna AR 1 , arranged on the substrate  590  to be spaced apart from each other at a predetermined interval. The plurality of conductive patches  910 ,  920 ,  930 , and  940  may include a first conductive patch  910 , a second conductive patch  920 , a third conductive patch  930 , and a fourth conductive patch  940 , which are arranged to form a beam pattern in a direction in which the first substrate surface  5901  is oriented. The first conductive patch  910 , the second conductive patch  920 , the third conductive patch  930 , and the fourth conductive patch  940  may be formed in a rhombus shape defined by sides that are not parallel to the short sides  591  and the long sides  591  of the substrate  590 . 
     According to certain embodiments, the antenna structure  900  may include a first feeding portion  911  arranged at a first point of the first conductive patch  910  and a second feeding portion  912  arranged at a second point spaced apart from the first feeding portion  911 . The wireless communication circuit (e.g., the wireless communication circuit  595  in  FIG. 5B ) may be electrically connected to the first feeding portion  911  and the second feeding portion  912  via a wiring structure arranged inside the substrate  590 . The first feeding portion  911  may be arranged on a first virtual line L 3  passing through the center C of the first conductive patch  910 . The second feeding portion  912  may be arranged on a second virtual line L 4  passing through the center C of the first conductive patch  910  and vertically intersecting the first virtual line L 3 . The feeding portions  911  and  912  may be arranged on the first imaginary line L 3  and the second virtual line L 4  which are defined not parallel to the short sides  591  and the long sides  592  of the substrate in the first conductive patch  910 . The antenna structure  900  may include a third feeding portion  921  and a fourth feeding portion  922  arranged on the second conductive patch  920  in substantially the same manner as the arrangement structure of the first feeding portion  911  and the second feeding portion  912  arranged on the first conductive patch  910 . The antenna structure  900  may include a fifth feeding portion  931  and a sixth feeding portion  932  arranged on the third conductive patch  930  in substantially the same manner as the arrangement structure of the first feeding portion  911  and the second feeding portion  912  arranged on the first conductive patch  910 . The antenna structure  900  may include a seventh feeding portion  941  and an eighth feeding portion  942  arranged on the fourth conductive patch  940  in substantially the same manner as the arrangement structure of the first feeding portion  911  and the second feeding portion  912  arranged on the first conductive patch  910 . Accordingly, the antenna structure  900  may be operated as an array antenna AR 1  via the first conductive patch  910 , the second conductive patch  920 , the third conductive patch  930 , and the fourth conductive patch  940 . For example, the wireless communication circuit (e.g., the wireless communication circuit  595  in  FIG. 5B ) may be configured such that a first polarized wave operating in a fifth direction (direction {circle around (5)}) is formed via the first feeding portion  911 , the third feeding portion  921 , the fifth feeding  931 , and the seventh feeding portion  941 , and may be configured such that a second polarized wave is formed in a sixth direction (direction {circle around (6)}) perpendicular to the first polarized wave via the second feeding portion  912 , the fourth feeding portion  922 , the sixth feeding portion  932 , and the eighth feeding portion  942 . The wireless communication circuit (e.g., the wireless communication circuit  595  in  FIG. 5B ) may be configured to transmit and/or receive a wireless signal in a frequency band in the range from about 3 GHz to about 300 GHz via the array antenna AR 1 . 
     According to certain embodiments, the conductive member  550  may include a plurality of first conductive slits  960  arranged on a first support portion  5511  corresponding to the second substrate surface  5902 . The plurality of first conductive slits  560  may include first sub-slits  961  (e.g., a first pattern) arranged at a position at which the first sub-slits  961  at least partially overlap the first conductive patch  910  when the first substrate surface  5901  is viewed from above (when the side member  720  is viewed from the outside), second sub-slits  962  (e.g., a second pattern) arranged at a position at which the second sub-slits  962  at least partially overlap the second conductive patch  920  when the first substrate surface  5901  is viewed from above, third sub-slits  963  (e.g., a third pattern) arranged at a position at which the third sub-slits  963  at least partially overlap the third conductive patch  930  when the first substrate surface  5901  is viewed from above, and fourth sub-slits  964  (e.g., a fourth pattern) arranged at a position at which the fourth sub-slits  964  at least partially overlap the fourth conductive patch  940  when the first substrate surface  5901  is viewed from above. The plurality of first conductive slits  960  may be arranged to have a length in a direction (e.g., direction {circle around (6)}) perpendicular to the vertical polarization direction (e.g., direction {circle around (5)}) of the above-described two polarized waves (e.g., a direction inclined at an angle of 45 degrees with respect to the long sides of the substrate  590 ). 
     The antenna structure  900  according to an exemplary embodiment of the disclosure may be helpful for suppressing radiation performance degradation of the array antenna AR 1  by reducing eddy current generated by the a peripheral conductive portion  721  of the housing  710  by inducing the eddy current to be close to in-phase via the plurality of conductive slits  960  formed to have a length in a direction perpendicular to a polarization direction (e.g., a vertical polarization direction) in at least a partial region of the conductive member  550  supporting the substrate  590 . 
     In certain embodiments, the conductive member can have a plurality of second conductive slits  560 - 1 , a plurality of third conductive slits  560 - 2 , and a plurality of fourth conductive slits  560 - 3 . 
       FIG. 10  is an exploded perspective view illustrating a state in which a conductive member is applied to an antenna structure according to certain embodiments of the disclosure. 
     In describing the antenna structure  500  and the conductive member  550  of  FIG. 10 , the same reference numerals are assigned to the components substantially the same as those of the antenna structure  500  and the conductive member  550  of  FIG. 6 , and a detailed description thereof may be omitted. 
     Referring to  FIG. 10 , the conductive member  550  may further include a plurality of second conductive slits  560 - 1  arranged in the second support portion  5512 , a plurality of third conductive slits  560 - 2  arranged in the third support portion  5513 , and a plurality of fourth conductive slits  560 - 3  arranged in the fourth support portion  5514 . In this case, the plurality of second conductive slits  560 - 1  may include, in the second support portion  5512 , fifth sub-slits  565  (e.g., a fifth pattern) arranged at a position corresponding to the first sub-slits  561 , sixth sub-slits  566  (e.g., a sixth pattern) arranged at a position corresponding to the second sub-slits  562 , seventh sub-slits  567  (e.g., a seventh pattern) arranged at a position corresponding to the third sub-slits  563 , and eighth sub-slits  568  arranged at a position corresponding to the fourth sub-slits  564 . The fifth to eighth sub-slits  565 ,  566 ,  567 , and  568  are also formed to have lengths in the same direction as the first to fourth sub-slits  561 ,  562 ,  563 , and  564 . The plurality of third conductive slits  560 - 2  and the plurality of fourth conductive slits  560 - 3  are also formed in the second support portion  5513  and the fourth support portion  5514  to have a length in a direction perpendicular to the vertical polarization direction (e.g., direction {circle around (3)} in  FIG. 7C ). 
       FIGS. 11A to 11J  are views illustrating various shapes and arrangement structures of a plurality of slits according to certain embodiments of the disclosure for comparison. 
     In the description made with reference to  FIGS. 11A to 11J , the “vertical direction” may mean a “V direction” that is a vertical polarization direction through the first feeding portion  511  of the conductive patch  510 , and the “horizontal direction” may mean an “H direction” that is a horizontal polarization direction through the second feeding portion  512  of the conductive patch  510 . In addition, in order to describe the arrangement relationship between at least one slit  5611  arranged in the conductive member  550  and at least one conductive patch  510 , only the at least one conductive patch  510  is illustrated with a dotted line, but it is apparent that at least one conductive patch  510  is arranged on a substrate (e.g., the substrate  590  in FIG.  6 ), as described above. 
       FIG. 11A  compares the performance of an antenna structure (e.g., the antenna structure  500  of  FIG. 6 ) may include a conductive patch  510  arranged on a substrate (e.g., the substrate  590  in  FIG. 6 ). The antenna structure  500  may include a first feeding portion  511  arranged on a first virtual line L 1  that passes through the center C of the conductive patch  510  and a second feeding portion  512  arranged on a second virtual line L 2  that passes through the center C of the conductive patch  510  and is orthogonal to the first virtual line L 1 . According to an embodiment, a wireless communication circuit (e.g., the wireless communication circuit  595  in  FIG. 5B ) may be configured to form a vertically polarized wave via the first feeding portion  511  and to form a horizontally polarized wave orthogonal to the vertically polarized wave via the second feeding portion  512 . The substrate (e.g., the substrate  590  in  FIG. 6 ) including the conductive patch  510  may be arranged to be at least partially supported by the conductive member  550 . The conductive member  550  may include at least one conductive slit  5611  arranged to at least partially overlap the conductive patch  510  when the conductive patch  510  is viewed from above. 
     According to certain embodiments, (a) in  FIG. 11A  illustrates an arrangement relationship between the conductive member  550  and the conductive patch  510  in which no conductive slit is present, (b) in  FIG. 11A  illustrates an arrangement relationship between the conductive member  550  including a plurality of conductive slits  5611  having a length in a direction (H direction) perpendicular to the vertical direction (V direction) and the conductive patch  510 , (c) in  FIG. 11A  illustrates an arrangement relationship between the conductive member  550  including a plurality of conductive slits  5611  having a length in an oblique direction of  45  degrees with respect to the vertical direction (V direction) and the conductive patch  510 , and (d) in  FIG. 11A  illustrates an arrangement relationship between the conductive member  550  including a plurality of conductive slits  5611  having a length in the same direction as the vertical direction (V direction) and the conductive patch  510 . 
     As illustrated in Table 2 below, it can be seen that, when the antenna structure  500  including the conductive patch  510  is operated in a predetermined frequency band (e.g., a band of about 28 GHz), in CDF 50% section, a gain of 2.4 dB is exhibited in (a) in  FIG. 11A  while a gain of 2.7 dB is exhibited in (b) in  FIG. 11A , a gain of 2.6 dB is exhibited in (c) in  FIG. 11A , and a gain of 2.3 dB is exhibited in (d) in  FIG. 11A . It can be seen that, for example, when the plurality of conductive slits  5611  formed in the conductive member  550  are formed to have a length in a direction (H direction) perpendicular to the direction in which a vertically polarized wave is formed (V direction), the most best gain improvement can be exhibited, and that the gain improvement effect becomes insignificant as a change is made to have a length in a direction matching the direction in which a vertically polarized wave is formed (V direction). In this case, it may mean that in the case of an antenna structure  500  having double polarization, when the plurality of conductive silts  5611  formed in the conductive member  550  are formed to have a length closer to a direction perpendicular to a vertically polarized wave (H direction), it may be helpful for obtaining a greater gain improvement effect and for improving the radiation performance of the antenna structure  500 .

     In making a description with reference to  FIGS. 11B to 11J , the same reference numerals are assigned to components substantially the same as those of  FIG. 11A , and a detailed description thereof may be omitted. 
     Referring to  FIG. 11B , the performance is compared when the conductive member  550  may include conductive slits  5611  all of which are arranged in the horizontal direction (H direction) in a region overlapping the conductive patch  510 . According to an embodiment, (a) in  FIG. 11B  illustrates an arrangement relationship of the conductive member  550  in which no conductive slit is present and the conductive patch  510 , (b) in  FIG. 11B  illustrates a state in which one conductive slit  5611  is arranged in the substantially central portion of the region overlapping the conductive patch  510 , (c) in  FIG. 11C  illustrates a state in which three conductive slits  5611  are arranged at a predetermined interval in the substantially the central portion of a region overlapping the conductive patch  510 , and (d) in  FIG. 11B  illustrates a state in which a plurality of conductive slits  5611  are arranged at a predetermined interval using the entire region overlapping the conductive patch  510 . 
     As illustrated in Table 3 below, it can be seen that, when the antenna structure  500  including the conductive patch  510  is operated in a predetermined frequency band (e.g., an about 28 GHz band), in CDF 50% section, a gain of 2.4 dB is exhibited in (a) in FIG.  11 B while a gain of 2.5 dB is exhibited in (b) in  FIG. 11B , a gain of 2.6 dB is exhibited in (c) in  FIG. 11B , and a gain of 2.7 dB is exhibited in (d) in  FIG. 11B . This may mean that, when a plurality of conductive slits  5611  are formed in the conductive member  550  and are arranged over the entire region overlapping the conductive patch  510 , it may be helpful for obtaining a greater gain improvement effect and for improving the radiation performance of the antenna structure  500 .

     Referring to  FIG. 11C , the per performance is compared where the conductive member  550  may include conductive slits  5611  all of which are arranged in the horizontal direction (H direction) in a region overlapping the conductive patch  510 . According to an embodiment, (a) in  FIG. 11C  illustrates a state in which a conductive slit  5611  having a first width (e.g., 0.05λ) is arranged in a substantially central portion of a region overlapping the conductive patch  510 , (b) in  FIG. 11C  illustrates a state in which a conductive slit  5611  having a second width (e.g., 0.1λ) greater than the first width is arranged in a substantially central portion of a region overlapping the conductive patch  510 , (c) in  FIG. 11C  illustrates a state in which a conductive slit  5611  having a third width (e.g., 0.25λ) greater than the second width is arranged in a substantially central portion of a region overlapping the conductive patch  510 , and (d) in  FIG. 11C  illustrates a state in which a conductive slit  5611  having a fourth width (e.g., 0.5λ) greater than the third width is arranged in a substantially central portion of a region overlapping the conductive patch  510 . 
     As illustrated in Table 4 below, it can be seen that, when the antenna structure  500  including the conductive patch  510  is operated in a predetermined frequency band (e.g., a band of about 28 GHz), in CDF 50% section, a gain of 2.4 dB is exhibited in (a) in  FIG. 11C  while a gain of 2.5 dB is exhibited in (b) in  FIG. 11C , a gain of 2.6 dB is exhibited in (c) in  FIG. 11C , and a gain of 2.5 dB is exhibited in (d) in  FIG. 11C . For example, it can be seen that, when the conductive slit  5611  formed in the conductive member  550  is extended beyond a predetermined width (e.g., 0.25λ), a gain improvement effect is rather reduced. This may mean that, when the width of the conductive slit  5611  arranged in the conductive member  550  is appropriately determined, it may be helpful for improving the radiation performance of the antenna structure  500 .

     Referring to  FIG. 11D , the performance is compared where the conductive member  550  may include conductive slits  5611  all of which are arranged in the horizontal direction (H direction) in a region overlapping the conductive patch  510 . According to an embodiment, (a) in  FIG. 11D  illustrates a state in which a plurality of conductive slits  5611  having a first width (e.g., 0.05λ) are arranged over the entire region overlapping the conductive patch  510 , (b) in  FIG. 11D  illustrates a state in which a plurality of conductive slits  5611  having a second width (e.g., 0.1λ) greater than the first width are arranged over the entire region overlapping the conductive patch  510 , and (c) in  FIG. 11D  illustrates a state in which one conductive slit  5611  having a third width (e.g., 0.5λ) greater than the second width is arranged over the entire region overlapping the conductive patch  510 . 
     As illustrated in Table 5 below, it can be seen that, when the antenna structure  500  including the conductive patch  510  is operated in a predetermined frequency band (e.g., a band of about 28 GHz), in CDF 50% section, a gain of 2.7 dB is exhibited in (a) in  FIG. 11D  while a gain of 2.6 dB is exhibited in (b) in  FIG. 11D , and a gain of 2.5 dB is exhibited in (c) in  FIG. 11D . For example, it can be seen that, when the width of the conductive slits  5611  formed in the conductive member  550  is small and the number of conductive slits  5611  is relatively great, the gain improvement effect is increased. This may mean that, when the width of the conductive slits  5611  arranged in the conductive member  550  is appropriately determined and a large number of slits are arranged at a predetermined interval, it may be helpful for improving the radiation performance of the antenna structure  500 .

     Referring to  FIG. 11E , the performance is compared where the conductive member  550  may include conductive slits  5611  arranged in the horizontal direction (H direction) in a region overlapping the conductive patch  510 . According to an embodiment, (a) in  FIG. 11E  illustrates a state in which a plurality of conductive slits  5611  having a first interval (e.g., 0.04λ) are arranged over the entire region overlapping the conductive patch  510 , (b) in  FIG. 11E  illustrates a state in which a plurality of conductive slits  5611  having a second interval (e.g., 0.12λ) greater than the first interval are arranged over the entire region overlapping the conductive patch  510 , (c) in  FIG. 11E  illustrates a state in which a plurality of conductive slits  5611  having a third interval (e.g., 0.2λ) greater than the second interval are arranged over the entire region overlapping the conductive patch  510 , and (d) in  FIG. 11E  illustrates a state in which a plurality of conductive slits  5611  having a fourth interval (e.g., 0.44λ) greater than the third interval are arranged over the entire region overlapping the conductive patch  510 . 
     As illustrated in Table 6 below, it can be seen that, when the antenna structure  500  including the conductive patch  510  is operated in a predetermined frequency band (e.g., an about 28 GHz band), in CDF 50% section, a gain of 2.7 dB is exhibited in (a) in  FIG. 11E , a gain of 2.6 dB is exhibited in (b) in  FIG. 11E , a gain of 2.6 dB is exhibited in (c) in  FIG. 11E , and a gain of 2.5 dB is exhibited in (d) in  FIG. 11E .

According to an embodiment, (a) in  FIG. 11F  illustrates an arrangement state of first sub-slits  561  having an overlapping region matching the first conductive patch  510  and second slits  562  having an overlapping region matching the second conductive patch  520 , wherein the first sub-slits and the second sub-slits have a first interval (e.g., 0.44λ) therebetween, (b) in  FIG. 11F  illustrates an arrangement state of first sub-slits  561  having a length in the horizontal direction (H direction) longer than the first conductive patch  510  and second sub-slits  562  having a length in the horizontal direction (H direction) longer than the second conductive patch  520 , wherein the first sub-slits and the second sub-slits have a second interval (e.g., 0.25λ) smaller than the first interval therebetween, (c) in  FIG. 11F  illustrates an arrangement state of first sub-slits  561  having a length in the horizontal direction (H direction) longer than the first conductive patch  510  and second sub-slits  562  having a length in the horizontal direction (H direction) longer than the second conductive patch  520 , wherein the first sub-slits and the second sub-slits have a third interval (e.g., 0.1λ) smaller than the second interval therebetween, and (d) in  FIG. 11F  illustrates an arrangement state of a plurality of conductive slits  565  overlapping the first conductive patch  510  and the second conductive patch  520  at the same time. 
     As illustrated in Table 7 below, it can be seen that, when the antenna structure  500  including the conductive patches  510  and  520  is operated in a predetermined frequency band (e.g., an about 28 GHz band), in CDF 50% section, a gain of 2.7 dB is exhibited in (a) in  FIG. 11F , a gain of 2.6 dB is exhibited in (b) in  FIG. 11F , a gain of 2.6 dB is exhibited in (c) in  FIG. 11F , and a gain of 2.5 dB is exhibited in (d) in  FIG. 11F . For example, it can be seen that, when the plurality of sub-slits  561  and  562  formed in the conductive member  550  have horizontal lengths that match those of the conductive patches  510  and  520 , respectively, and are formed to overlap the conductive patches, respectively, the gain improvement effect is improved.

     Referring to  FIG. 11G , in the region overlapping the conductive patch  510 , the conductive member  550  may include conductive slits  5611  all of which are arranged in the horizontal direction (H direction) and at least one vertical slit  5612 ,  5613 ,  5614 , or  5615  which at least partially vertically crosses the conductive slits  5611  in the horizontal direction (H direction). According to an embodiment, (a) in  FIG. 11G  illustrates a state in which a plurality of conductive slits  5611  having a length in the horizontal direction (H direction) are arranged over the entire region overlapping the conductive patch  510 , (b) in  FIG. 11G  illustrates a state in which, in addition to the conductive slits  5611  arranged to have a length in the horizontal direction (H direction), one vertical slot  5612 , which vertically crosses substantially central portions of the conductive slots, is further included, and (c) in  FIG. 11G  illustrates a state in which, in addition to the conductive slits  5611  arranged to have a length in the horizontal direction (H direction), three vertical slots  5613 ,  5614 , and  5615 , which are arranged substantially at a predetermined interval and vertically cross the conductive slits. 
     As illustrated in Table 8 below, it can be seen that, when the antenna structure  500  including the conductive patch  510  is operated in a predetermined frequency band (e.g., a band of about 28 GHz), in CDF 50% section, a gain of 2.7 dB is exhibited in (a) in  FIG. 11G , a gain of 2.5 dB is exhibited in (b) in  FIG. 11G , and a gain of 2.6 dB is exhibited in (c) in  FIG. 11G . For example, it can be seen that, when only the conductive slits  5611  formed to have a length in the horizontal direction (H direction) are arranged in the conductive member  550 , the gain improvement effect is increased. In addition, it can be seen that, when the number of vertical slots  5613 ,  5614 , and  5615  vertically crossing the conductive slits  5611  formed to have a length in the horizontal direction (H direction) increases, it may be helpful for improving the radiation performance of the antenna structure  500 .

     In making a description with reference to  FIG. 11H , the same reference numerals are assigned to the components substantially the same as those of  FIG. 11F , and a detailed description thereof may be omitted. 
     Referring to  FIG. 11H , (a) in  FIG. 11H  illustrates an arrangement state of first sub-slits  561  having an overlapping region matching a first conductive patch  510  and second sub-slits  562  having an overlapping region matching a second conductive patch  520 , and (b) in  FIG. 11H  illustrates a state in which a vertical slot  5622  formed in the vertical direction (V direction) is arranged in a substantially central portion between the first sub-slits  561  and the second sub-slits  562 . 
     As illustrated in Table 9 below, it can be seen that, when the antenna structure  500  including the conductive patches  510  and  520  is operated in a predetermined frequency band (e.g., an about 28 GHz band), in CDF 50% section, a gain of 2.7 dB is exhibited in (a) in  FIG. 11H , and a gain of 2.6 dB is exhibited in (b) in  FIG. 11H . For example, it can be seen that the gain is relatively improved in both cases of (a) and (b) in  FIG. 11I , compared to the case in which no conductive slit is arranged in the conductive member  550 . In addition, it can be seen that, when an additional conductive slit (e.g., the vertical slit  5622 ) is not arranged between the first sub-slits  561  and the second sub-slits  562  formed to have a length in the horizontal direction (H direction), the radiation performance of the antenna structure  500  is relatively further improved.

     Referring to  FIG. 11I , (a) in  FIG. 11I  illustrates a state in which first sub-slits arranged at a position at which the first sub-slits at least partially overlap a first conductive patch (e.g., the first conductive patch  510  in  FIG. 11H ) and second sub-slits  562  arranged at a position at which the second sub-slits  562  at least partially overlap a second conductive patch (e.g., the second conductive patch  520  in  FIG. 11H ) are arranged in the first support portion  5511  of the conductive member  550 , and (b) in  FIG. 11I  illustrates a state in which third sub-slits  565  (e.g., the fifth sub-slits  565  in  FIG. 10 ) arranged at a position corresponding to the first sub-slits  561  and fourth slits  566  (e.g., the sixth sub-slits  566  in  FIG. 10 ) arranged at a position corresponding to the second sub-slits  562  are additionally arranged in a second support portion  5512  of the conductive member. 
     As illustrated in Table 10 below, it can be seen that, when the antenna structure  500  including the conductive patches  510  and  520  is operated in a predetermined frequency band (e.g., a band of about 28 GHz), in CDF 50% section, a gain of 2.7 dB is exhibited in (a) in  FIG. 11I , and a gain of 2.6 dB is exhibited in (b) in  FIG. 11I . For example, it can be seen that the gain is relatively improved in both cases of (a) and (b) in  FIG. 11I , compared to the case in which no conductive slit is arranged in the conductive member  550 . In addition, it can be seen that, when the first sub-slits  561  and the second sub-slits  562  formed to have a length in the horizontal direction (e.g., H direction) are arranged in the first support portion  5511  of the conductive member  550 , the radiation performance of the antenna structure  500  is relatively further improved.

     Referring to  FIG. 11J , (a) in  FIG. 11J  is a view illustrating a state in which conductive slits  5611  having a length in the horizontal direction (H direction) are arranged over the entire region overlapping the conductive patch  510  at a predetermined interval, (b) and (c) in  FIG. 11J  are views illustrating a state in which a plurality of micro slits  5616  and  5617  are arranged at predetermined intervals in the horizontal direction (H direction) and the vertical direction (V direction) over the entire region overlapping the conductive patch  510 , (d) in  FIG. 11J  is a view illustrating a state in which a plurality of micro slits  5618  are arranged in a region except for a cross-shaped space including a region overlapping the center C of the conductive patch  510 , (e) in  FIG. 11J  is a view illustrating a state in which conductive slits  5611  having a length in the horizontal direction (H direction) are alternately arranged with a plurality of micro slits  5617  such that each conductive slits is arranged between adjacent rows of micro slits  5617 , and (f) in  FIG. 11J  is a view illustrating a state in which a cross-shaped slit  5619  including a region overlapping the center C of the conductive patch  510  and a plurality of micro slits  5616  arranged around the cross-shaped slit  5616  are arranged. 
     As illustrated in Table 11 below, it can be seen that, when the antenna structure  500  including the conductive patch  510  is operated in a predetermined frequency band (e.g., a band of about 28 GHz), in CDF 50% section, a gain of 2.7 dB is exhibited in (a) in  FIG. 11J , a gain of 2.4 dB is exhibited in (b) to (d) in  FIG. 11J , and a gain of 2.6 dB is exhibited in (e) and (f) in  FIG. 11J . For example, it can be seen that the gain is relatively improved in all cases of (a) to (f) in  FIG. 11J , compared to the case in which no conductive slit is arranged in the conductive member  550 . In addition, it can be seen that, when the conductive slits  5611  having a length in the horizontal direction (H direction) are arranged over the entire area overlapping the conductive patch  510 , the radiation performance of the antenna structure  500  is relatively further improved.
