CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation application, claiming priority under § 365(c), of an International application No. PCT/KR2022/000039, filed on Jan. 4, 2022, which is based on and claims the benefit of a Korean patent application number 10-2021-0003810, filed on Jan. 12, 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., electronic devices for communication) are commonly used in daily life, and thus the use of contents is increasing exponentially. Due to the rapid increase in contents use, a network capacity is gradually reaching a limit thereof, and after the commercialization of 4th generation (4G) communication system, in order to meet the increasing demand for wireless traffic data, a communication system (e.g., 5th generation (5G), pre-5G communication system, or new radio (NR)) that transmits and/or receives a signal using a frequency of high-frequency (e.g., mmWave) bands (e.g., 3 GHz to 300 GHz bands) is being researched. 
     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 technology may substantially transmit and receive wireless signals using a frequency in a range of 3 GHz to 100 GHz, and an efficient mounting structure for overcoming a high free space loss due to frequency characteristics and for increasing a gain of an antenna, and a new antenna structure (e.g., antenna module) corresponding thereto is being developed. The antenna structure may include an array antenna in which the various number of antenna elements (e.g., conductive patches and/or conductive patterns) are disposed at regular intervals in a dielectric structure (e.g., substrate). These antenna elements may be disposed to form a beam pattern in any one direction inside the electronic device. For example, the antenna structure may be disposed to form a beam pattern toward at least a portion of a front surface, a rear surface, and/or a side surface in an internal space of the electronic device. 
     In order to reinforce rigidity and form a beautiful appearance, the electronic device may include a conductive part (e.g., metal member) disposed in at least a portion of the housing and a non-conductive part (e.g., polymer member) coupled to the conductive part. The conductive part may be at least partially omitted in a portion facing an antenna structure disposed in the internal space of the electronic device, and the omitted portion may be replaced with the non-conductive part. 
     However, the conductive part disposed close to the antenna structure may be disposed to at least partially cover a radiation direction of a beam pattern of the antenna structure, and such a disposition structure may deteriorate a radiation performance of the antenna structure. In order to solve such a problem, the conductive part may be disposed at a position relatively far from the antenna structure, but this may cause a decrease in rigidity of the electronic device. 
     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 and an electronic device including the same constituted to reduce radiation performance degradation through conductive additional structures disposed at a periphery of an antenna structure. 
     Another aspect of the disclosure is to provide an antenna and an electronic device including the same, which can help to reinforce rigidity of the electronic device by reducing radiation performance degradation even though a conductive part is disposed near an antenna structure. 
     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 including a conductive part and a non-conductive part coupled to the conductive part, an antenna structure including a substrate disposed in an internal space of the housing and at least one antenna element disposed to form a beam pattern in a first direction in the substrate, at least one conductive dummy plate disposed between the at least one antenna element and the housing in the internal space of the housing, and a wireless communication circuit configured to transmit and/or receive a wireless signal in a specified frequency band through the at least one antenna element, wherein the antenna structure is disposed at a position at least partially overlapped with the non-conductive part when the housing is viewed from the outside, and the at least one conductive dummy plate is disposed at a position at least partially overlapped with the at least one antenna element when the housing is viewed from the outside. 
     In accordance with another aspect of the disclosure, an electronic device is provided. The electronic device includes a housing including a conductive part and a non-conductive part coupled to the conductive part, and an antenna structure disposed in the housing, wherein the antenna structure includes a dielectric structure, at least one conductive patch disposed to form a beam pattern in a first direction in the dielectric structure, and at least one conductive dummy plate disposed between the at least one conductive patch and the housing in the dielectric structure, and a wireless communication circuit configured to transmit and/or receive a wireless signal in a specified frequency band through the at least one conductive patch, wherein the antenna structure is disposed at a position at least partially overlapped with the non-conductive part when the housing is viewed from the outside, and the at least one conductive dummy plate is disposed at a position at least partially overlapped with the at least one conductive patch when the housing is viewed from the outside. 
     Advantageous Effects 
     An antenna structure according to an embodiment of the disclosure can reduce radiation performance degradation by expanding a beam width in a designated direction through a conductive dummy plate spaced apart at a specified interval from at least one antenna element in a radiation direction. Further, because the conductive part of the housing may be disposed near the antenna structure while reducing radiation performance degradation of the antenna structure by the conductive dummy plate, thereby helping to reinforce rigidity of the electronic device.

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 Above 6RF 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 various embodiments, in a low frequency band (e.g., 28 GHz band) that may affect a radiation performance by the conductive part (e.g., the conductive part  721  of  FIG. 7B ) of the housing (e.g., the housing  710  of  FIG. 7B ), in order to prevent performance degradation of vertical polarization, the conductive dummy plates  610  and  620  may have a length in a direction (direction {circle around (3)}) perpendicular to the vertical polarization direction (direction {circle around (2)}) and be disposed so that the first plate surface  6101  faces in a direction (direction {circle around (2)}) perpendicular to the surface of the conductive patches  610  and  620 .

       FIG. 6  is a diagram illustrating a radiation pattern of an antenna structure according to presence or absence of a conductive dummy plate according to an embodiment of the disclosure. 
     Referring to  FIG. 6 , in the antenna structure  500  operating in a 28 GHz band of  FIG. 5A , in a case (pattern  603 ) in which the conductive dummy plates  610  and  620  are applied, it can be seen that a radiation performance of horizontal polarization (H-polarization) is similar to that of a case (pattern  604 ) in which the conductive dummy plates  610  and  620  are not applied, whereas in a case (pattern  601 ) in which the conductive dummy plates  610  and  620  are applied, it can be seen that a radiation performance of vertical polarization (V-polarization) is improved further than that of a case (pattern  602 ) in which the conductive dummy plates  610  and  620  are not applied. For example, in vertical polarization, when the conductive dummy plates  610  and  620  are applied, it can be seen that in a radiation performance of the antenna structure  500 , there has been improved a null point existing in an elevation 90 degree area (area  605 ) of a case in which the conductive dummy plates  610  and  620  are not applied and that a radiation performance has been improved by extending a beam width in an upper area (area  606 ) and a lower area (area  607 ) of the electronic device. 
     Numerically, referring to Table 1, the antenna structure  500  operating in a low frequency band (n261 band) exhibits a gain of 6.5 dB before applying the conductive dummy plates  610  and  620  in a 50% section of a cumulative distribution function (CDF), but after the conductive dummy plates  610  and  620  are applied, the antenna structure  500  exhibits a gain of 6.9 dB; thus, it can be seen that a gain of 0.4 dB is substantially improved. Further, the antenna structure  500  operating in a high frequency band (n260 band) exhibits a gain of 7.0 dB before applying the conductive dummy plates  610  and  620  in a 50% section of the CDF, but after the conductive dummy plates  610  and  620  are applied, the antenna structure  500  exhibits a gain of 7.1 dB; thus, it can be seen that a gain of 0.1 dB is substantially improved.
