This application is based on and claims priority under 35 U.S.C. 119(a) of a Korean patent application number 10-2019-0056592 filed on May 14, 2019, in the Korean Intellectual Property Office, and of a Korean patent application number 10-2020-0031173, filed on Mar. 13, 2020, in the Korean Intellectual Property Office, the disclosures of each of which are incorporated by reference herein in their entireties.
BACKGROUND
1. Field
The disclosure relates to an antenna and an electronic device including the same.
2. Description of Related Art
With the development of wireless communication technology, electronic devices (e.g., communication electronic devices) are commonly used in daily life; thus, use of content is increasing exponentially. Because of such rapid increase in the use of content, a network capacity is reaching its limit. After commercialization of 4th generation (4G) communication systems, in order to meet growing wireless data traffic demand, a communication system (e.g., 5th generation (5G) or pre-5G communication system, or new radio (NR))) that transmits and/or receives signals using a frequency of a high frequency (e.g., millimeter wave (mmWave)) band (e.g., 3 GHz to 300 GHz band) is being studied.
Next-generation wireless communication technologies are currently developed to permit signal transmission/reception using frequencies in the range of 3 GHz to 100 GHz, overcome 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. This antenna module may include an array-type antenna module in which various numbers of antenna elements (e.g., conductive patches) are arranged at regular intervals. These antenna elements may be disposed in an electronic device so as to form a beam pattern in one direction, for example, toward a front, rear, or lateral surface of the electronic device from an inner space of the electronic device.
The electronic device may include a conductive portion (e.g., a metal member) disposed on at least a part of a housing to reinforce the rigidity and create a beautiful appearance, and a non-conductive portion (e.g., a polymer member) combined with the conductive portion. However, when the conductive portion is placed near the antenna module disposed inside the electronic device, the radiation performance and radiation sensitivity of the antenna module may be deteriorated.
The non-conductive portion may be insert-injected into or structurally combined with the conductive portion to form a single housing. Further, in order to prevent the conductive portion and the non-conductive portion from being separated by an external impact, a boundary region between the conductive portion and the non-conductive portion may have an engaging structure composed of at least one protrusion and at least one recess for receiving the at least one protrusion. A portion of the housing faced by the antenna module that forms a beam pattern in a specific direction from the inner space of the electronic device may be formed as the non-conductive portion. Thus, the boundary region between the conductive portion and the non-conductive portion may be placed near the antenna module, and a concave part of the conductive portion produced by the engaging structure composed of the protrusion and the recess may also be placed near the antenna module.
Unfortunately, this concave part may cause an excitation current, so that the antenna module may be confronted with the degradation of radiation performance and radiation sensitivity.
The above information is presented as background information only, and 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.

Referring to FIG. 1, an electronic device 101 in a network environment 100 may communicate with an electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or an electronic device 104 or a server 108 via a second network 199 (e.g., a long-range wireless communication network). The electronic device 101 may communicate with the electronic device 104 via the server 108. The electronic device 101 includes a processor 120, memory 130, an input device 150, an audio output device 155, a display device 160, an audio module 170, a sensor module 176, an interface 177, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, and/or an antenna module 197. In some embodiments, at least one (e.g., the display device 160 or the camera module 180) of the components may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101.

The receiver may be implemented as separate from, or as part of the speaker.
The display device 160 may visually provide information to the outside (e.g., a user) of the electronic device 101. The display device 160 may include, for example, a display, a hologram device, or a projector and control circuitry to control a corresponding one of the display, hologram device, and projector. The display device 160 may include touch circuitry adapted to detect a touch, or sensor circuitry (e.g., a pressure sensor) adapted to measure the intensity of force incurred by the touch.
The audio module 170 may convert a sound into an electrical signal and vice versa. The audio module 170 may obtain the sound via the input device 150, or output the sound via the audio output device 155 or a headphone of an external electronic device (e.g., an electronic device 102) directly (e.g., wiredly) or wirelessly coupled with the electronic device 101.
The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. The sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.
The interface 177 may support one or more specified protocols to be used for the electronic device 101 to be coupled with the external electronic device (e.g., the electronic device 102) directly (e.g., wiredly) or wirelessly. The interface 177 may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.
A connection terminal 178 may include a connector via which the electronic device 101 may be physically connected with the external electronic device (e.g., the electronic device 102). The connection terminal 178 may include, for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector (e.g., a headphone connector).

The haptic module 179 may include, for example, a motor, a piezoelectric element, or an electric stimulator.
The camera module 180 may capture an image or moving images. The camera module 180 may include one or more lenses, image sensors, image signal processors, or flashes.
The power management module 188 may manage power supplied to the electronic device 101. The power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).
The battery 189 may supply power to at least one component of the electronic device 101. The battery 189 may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell.
The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the AP) and supports a direct (e.g., wired) communication or a wireless communication. The communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as BluetoothTM, 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.
The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. The antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). The antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. Another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.
At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).
Commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. All or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.
An electronic device according to an embodiment may be one of various types of electronic devices.

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 a 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).

In another embodiment, the at least one extension part 5511 and 5512 may be extended from the second support part 552. Therefore, the antenna module 500 may be supported by the first and second support parts 551 and 552 of the conductive member 550 and fixed to the conductive portion (e.g., the conductive portion 321 in FIG. 7) of the lateral member (e.g., the lateral member 320 in FIG. 7) and/or to the conductive portion of the support member (e.g., the first support member 3211 in FIG. 7) through the at least one extension part 5511 and 5512 by a fastening member such as a screw.
FIG. 7 is a cross-sectional view partially showing an electronic device, viewed from line A-A′ in FIG. 3B, according to an embodiment of the disclosure.
Referring to FIG. 7, the electronic device 300 may include the housing 310 that includes the front plate 302 (e.g., a front cover) facing a first direction (e.g., the −Z direction), the rear plate 311 (e.g., a rear cover) facing a direction (e.g., the Z direction) opposite to the front plate 302, and the lateral member 320 surrounding an inner space 3001 between the front plate 302 and the rear plate 311. According to an embodiment, the lateral member 320 may include a conductive portion 321 (e.g., a metal member) disposed at least in part and a non-conductive portion 322 (e.g., a polymer member) insert-injected into the conductive portion 321. In another embodiment, the non-conductive portion 322 may be replaced with a space or any other dielectric material. In still another embodiment, the non-conductive portion 322 may be structurally combined with the conductive portion 321. According to an embodiment, the lateral member 320 may include a support member 3211 (e.g., the first support member 3211 in FIG. 3C) extended partially into the inner space 3001. According to an embodiment, the first support member 3211 may be extended from the lateral member 320 into the inner space 3001 or formed by a structural combination with the lateral member 320. According to an embodiment, the first support member 3211 may be extended from the conductive portion 321. According to an embodiment, the support member 3211 may support at least a portion of the antenna module 500 disposed in the inner space 3001. According to an embodiment, the first support member 3211 may be disposed to support at least a portion of a display 301. According to an embodiment, the display 301 may be disposed to be visible from the outside through at least a portion of the front plate 302. According to an embodiment, the display 301 may include a flexible display.
According to various embodiments, the antenna module 500 may be disposed in a direction perpendicular to the front plate 302 in the inner space 3001 of the electronic device 300. According to an embodiment, the antenna module 500 may be mounted such that the array antenna AR1 including conductive patches (e.g., the conductive patches 510, 520, 530, and 540 in FIG. 5A) faces the lateral member 320. For example, the antenna module 500 may be disposed such that the first surface 591 of the PCB 590 faces the lateral member 320 and thus a beam pattern is formed in a direction (denoted by {circle around (1)}) faced by the lateral member 320. According to an embodiment, at least a portion of the lateral member 320 faced by the antenna module 500 may be formed as the non-conductive portion 322 such that a beam pattern is formed in a direction (denoted by {circle around (1)}) faced by the lateral member 320. According to an embodiment, the electronic device 300 may include a device substrate 340 (e.g., the PCB 340 in FIG. 3C) disposed in the inner space 3001. According to an embodiment, although not shown, the antenna module 500 may be electrically connected to the device substrate 340 through an electrical connection member (e.g., an FPCB connector).
FIG. 8A is a view partially showing an electronic device, viewed from line B-B′ in FIG. 3B, according to an embodiment of the disclosure.
FIG. 8A shows only the conductive portion 321 when the rear plate 311 is viewed from above, while substantially omitting the non-conductive portion 322. The non-conductive portion 322 may be filled with an insulating member such as a polymer member.
Referring to FIG. 8A, the lateral member 320 may include the non-conductive portion 322 (e.g., a polymer member) disposed to correspond to a region where a beam pattern of the antenna module 500 is formed. According to an embodiment, the non-conductive portion 322 may be insert-injected into the conductive portion 321. According to an embodiment, a boundary region between the non-conductive portion 322 and the conductive portion 321 may be disposed near the antenna module 500. According to an embodiment, the boundary region may have an engaging structure for disallowing the conductive portion 321 and the non-conductive portion 322, after combined with each other, to be separated from each other by external impact. According to an embodiment, the boundary region may be placed at a position which is not overlapped with the antenna module 500 when the lateral member 320 is viewed from the outside. For example, the conductive portion 321 may include a concave portion 3221 formed concavely in the boundary region. According to an embodiment, the non-conductive portion 322 may be formed as a part of the lateral member 320 of the electronic device 300 by being filled in the concave portion 3221 through insert injection.
According to various embodiments, when the concave portion 3221 is formed deeper than a predetermined depth, an excitation current may be generated by a current trap phenomenon through the concave portion 3221. This excitation current may degrade the radiation performance of the antenna module 500. Therefore, the depth and/or shape of the concave portion 3221 may become important parameters in determining the antenna radiation performance.
According to various embodiments, when the rear plate 311 is viewed from above as in FIG. 3B, the concave portion 3221 may be formed such that an inclined angle (θ) thereof does not exceed about 60 degrees. As illustrated, the inclined angle (θ) is an angle formed by a starting point of the concave portion 3221 (i.e., a contact point with the lateral member 320) with respect to a virtual line (L) formed from both ends of the PCB 590 toward the lateral member 320 (i.e., in a direction perpendicular to the lateral member 320 as denoted by {circle around (1)}). In addition, having the inclined angle (θ) does not exceed about 60 degrees, the concave portion 3221 may be formed at a certain depth and in a certain shape. The shape of the concave portion 3221 may be varied such as a curved shape or a flat shape. In a certain embodiment, the concave portion 3221 may be formed such that the inclined angle (θ) does not exceed about 60 degrees with respect to a virtual line (L) formed from both ends of the array antenna AR1 toward the lateral member 320. According to an embodiment, the inclined angle (θ) of the concave portion 3221 may range from about 30 degrees to about 60 degrees in consideration of beam coverage (e.g., ±30 degrees with respect to the virtual line (L)) of the array antenna AR1. According to an embodiment, the concave portion 3221 may be gradually narrowed or widened along the inclination angle (θ) with respect to the virtual line (L). According to an embodiment, the inner surface of the concave portion 3221 may be a curved plane having a specific radius of curvature.
According to an embodiment, the concave portion 3221 may prevent an unwanted separation between the non-conductive portion 322 and the conductive portion 321 in a horizontal direction (denoted by {circle around (1)}) by external impact. According to an embodiment, the concave portion 3221 may have at least one slit 3221a further recessed from the inner surface of the concave portion 3221. According to an embodiment, the slit 3221a may be formed in a direction substantially parallel to the rear plate 311. According to an embodiment, the slit 3221a may increase a contact area between the conductive portion 321 and the non-conductive portion 322 and thereby improve an engaging force. According to an embodiment, the slit 3221a may prevent an unwanted separation between the non-conductive portion 322 and the conductive portion 321 in a vertical direction (denoted by {circle around (3)}) by external impact. According to an embodiment, the radiation characteristics of the antenna module 500 may be determined depending on the shape, depth, width, and/or number of the slits 3221a. 
According to various embodiments, a distance (d) between the concave portion 3221 and the PCB 590, as illustrated, may be determined so as not to exceed a quarter of wavelength (i.e., 1⁄4*λ) in the greatest operating frequency wavelength carrier of the antenna module.
FIG. 8B is a view partially showing a lateral member having a non-conductive region around an antenna module according to an embodiment of the disclosure.
Referring to FIG. 8B, the lateral member 320 may include, in the conductive portion 321, at least one non-conductive region 322a disposed around the antenna module 500. According to an embodiment, the at least one non-conductive region 322a may be disposed near both right and left ends of the PCB 590 of the antenna module 500 when the lateral member 320 is viewed from the outside. According to an embodiment, the at least one non-conductive region 322a may be formed to cross, at least in part, the lateral member 320 between the PCB 590 and the concave portion 3221. According to an embodiment, the at least one non-conductive region 322a may be formed through injection of the same material as or a different material from that of the non-conductive portion 322. The at least one non-conductive region 322a may prevent a double radiation phenomenon caused by the concave portion 3221 when a beam is emitted from the array antenna AR1.
FIGS. 9A and 9B are graphs showing radiation patterns and gains by horizontal polarization (H-pol) of an antenna module according to various embodiments of the disclosure.
Referring to FIGS. 9A and 9B, compared to horizontal polarization 901 and gain 903 of a typical antenna module in which a concave portion has an inclined angle (θ) that exceeds about 60 degrees, horizontal polarization 902 and gain 904 of the antenna module 500 according to an embodiment of the disclosure exhibit relatively excellent sensitivity characteristics and gain improved by about 2.5 dB. The reason is that, as described above with reference to FIGS. 7 and 8A, a concave portion (e.g., the concave portion 3221 in FIG. 8A) is formed in a conductive portion (e.g., the conductive portion 321 in FIG. 8A) such that an inclined angle (θ) thereof does not exceed about 60 degrees.
FIG. 9C is a graph showing a radiation pattern by vertical polarization (V-pol) of an antenna module according to an embodiment of the disclosure.
Referring to FIG. 9C, compared to vertical polarization 905 of a typical antenna module in which a concave portion has an inclined angle (θ) that exceeds about 60 degrees, vertical polarization 906 of the antenna module 500 according to an embodiment of the disclosure exhibit relatively excellent sensitivity characteristics. The reason is that, as described above with reference to FIGS. 7 and 8A, a concave portion (e.g., the concave portion 3221 in FIG. 8A) is formed in a conductive portion (e.g., the conductive portion 321 in FIG. 8A) such that an inclined angle (θ) thereof does not exceed about 60 degrees.
FIG. 10 is a cross-sectional view partially showing an electronic device, viewed from line C-C′ in FIG. 3A, according to an embodiment of the disclosure.
FIG. 11A is a perspective view partially showing a housing according to an embodiment of the disclosure.
In the following description of the electronic device 300, the same components as those described above are denoted by the same reference numerals, and detailed descriptions thereof may be omitted.
According to various embodiments, in the antenna module 500 that performs radiation in a direction (denoted by {circle around (1)}) facing from the inner space 3001 of the electronic device 300 to the lateral member 320, a cancellation phenomenon (or null phenomenon) may occur due to a phase difference between a beam pattern directly radiated from the antenna module 500 and a beam pattern reflected by the first support member 3211 disposed nearby. This may degrade the radiation performance of the antenna module 500. Various embodiments of the disclosure may have a configuration for preventing the performance degradation of the antenna through a structural change of the lateral member 320.
Referring to FIGS. 10 and 11A, the electronic device 300 may include the housing 310 that includes the front plate 302 (e.g., a front cover), the rear plate 311 (e.g., a rear cover) facing a direction opposite to the front plate 302, and the lateral member 320 surrounding the inner space 3001 between the front plate 302 and the rear plate 311. According to an embodiment, the lateral member 320 may have a first surface 3201 facing the front plate 302, and a second surface 3202 facing a direction opposite to the first surface 3201. According to an embodiment, the lateral member 320 may include the conductive portion 321 (e.g., a metal member) disposed at least in part, and a first non-conductive portion 3224 (e.g., the non-conductive portion 322 in FIG. 7, e.g., a polymer member) insert-injected into the conductive portion 321. According to an embodiment, the lateral member 320 may include the support member 3211 (e.g., the first support member 3211 in FIG. 3C) extended at least partially into the inner space 3001.
According to various embodiments, the front plate 302 may be disposed on the first surface 3201 of the lateral member 320. According to an embodiment, the front plate 302 may be supported by at least a part of the lateral member 320 including the first support member 3211. According to an embodiment, the electronic device 300 may include a display 301 disposed between the front plate 302 and the lateral member 320. According to an embodiment, the display 301 may include a polarization layer (not shown), a display panel (not shown), at least one additional layer (e.g., a cushion layer and/or an embossing layer, not shown), and/or a conductive sheet 3011, which are stacked sequentially on the rear surface of the front plate 302. According to an embodiment, the display 301 may include the conductive sheet 3011 (e.g., a Cu sheet) disposed for noise shielding on the rear surface of the display panel.
According to various embodiments, the antenna module 500 may be disposed in a direction perpendicular to the front plate 302 in the inner space 3001 of the electronic device 300 through a conductive member 550. According to an embodiment, the antenna module 500 may be mounted such that an array antenna AR1 including conductive patches (e.g., the conductive patches 510, 520, 530, and 540 in FIG. 5A) (e.g., a plurality of antenna elements) face the lateral member 320. For example, the antenna module 500 may be disposed such that a first surface 591 of a PCB 590 faces the lateral member 320, and thus a beam pattern may be formed in a direction (denoted by {circle around (1)}) faced by the lateral member 320 of the electronic device 300. According to an embodiment, at least a part of the lateral member 320 facing the antenna module 500 may be the first non-conductive portion 3224 that allows a beam pattern to be formed in the direction (denoted by {circle around (1)}) faced by the lateral member 320. According to an embodiment, the electronic device 300 may include a device substrate 340 (e.g., the PCB 340 in FIG. 3C) disposed in the inner space 3001. According to an embodiment, although not shown, the antenna module 500 may be electrically connected to the device substrate 340 through an electrical connector (e.g., an FPCB connector).
According to various embodiments, at least a part of the conductive portion 321 of the lateral member 320 may be formed in a shape for supporting the display 301 and the front plate 302 above one side of the antenna module 500. Therefore, the conductive portion 321 of the lateral member 320 may affect, at least in part, a beam pattern radiated in a direction of the front plate 302.
According to various embodiments, the lateral member 320 may further include at least one second non-conductive portion 3222 disposed at a position corresponding to the array antenna AR1 of the antenna module 500 in the direction of the front plate 302. According to an embodiment, the second non-conductive portion 3222 may be inserted-injected together with the first non-conductive portion 3224 (e.g., the non-conductive portion 322 in FIG. 7) into the conductive portion 321. In another embodiment, the first non-conductive portion 3224 and the second non-conductive portion 3222 may be formed of insulating materials having different properties (e.g., different dielectric constants). In still another embodiment, the second non-conductive portion 3222 may be an empty space in which no insulating material is disposed. The second non-conductive portion 3222 may be formed in the first surface 3201 (e.g., a flat portion) of the lateral member 320 and/or a curved surface extended laterally from the first surface 3201. According to an embodiment, the at least one second non-conductive portion 3222 may be disposed at a position overlapped at least in part with the array antenna AR1 when the front plate 302 is viewed from above and/or when the lateral member 320 is viewed from outside. According to an embodiment, a plurality of second non-conductive portions 3222 may be disposed at positions corresponding to respective conductive patches (e.g., the first conductive patch 510, the second conductive patch 520, the third conductive patch 530, and/or the fourth conductive patch 540 in FIG. 5). Therefore, a beam pattern radiated from the antenna module 500 in the direction of the lateral member 320 is increased upward in radiation length up to the conductive sheet 3011 of the display 301 through the second non-conductive portion 3222. This may help to reduce the cancellation phenomenon as compared to an antenna module disposed near the lateral member 320 having no second non-conductive portion 3222.
FIG. 11B is a perspective view partially showing a housing according to an embodiment of the disclosure.
Referring to FIG. 11B, the lateral member 320 may include a second non-conductive portion 3223 disposed in the first surface 3201 and/or a curved surface extended laterally from the first surface 3201. According to an embodiment, the second non-conductive portion 3223 may be formed in a size overlapped at least in part with a plurality of conductive patches (e.g., the first conductive patch 510, the second conductive patch 520, the third conductive patch 530, and/or the fourth conductive patch 540 in FIG. 5) of the array antenna AR1 when the front plate 302 is viewed from above and/or when the lateral member 320 is viewed from outside.
FIGS. 12A and 12B are graphs showing radiation patterns and gains by horizontal polarization (H-pol) of the antenna module of FIG. 10 according to various embodiments of the disclosure.
Referring to FIGS. 12A and 12B, compared to horizontal polarization 1201 and gain 1203 of a typical antenna module in which a lateral member has a conductive portion, horizontal polarization 1202 and gain 1204 of the antenna module (e.g., the antenna module 500 in FIG. 10) according to an embodiment of the disclosure exhibit relatively excellent sensitivity characteristics and high gain. The reason is that, as described above, a lateral member (e.g., the lateral member 320 in FIG. 10) of the antenna module according to an embodiment may include a second non-conductive portion (e.g., the second non-conductive portion 3222 in FIG. 10) disposed at a position overlapped at least in part with an array antenna (e.g., the array antenna AR1 in FIG. 10) when a front plate (e.g., the front plate 302 in FIG. 10) is viewed from above and/or when the lateral member is viewed from outside.
FIG. 13 is a cross-sectional view partially showing an electronic device including a conductive connection member according to an embodiment of the disclosure.
Referring to FIG. 13, when an antenna module (e.g., the antenna module 500 in FIG. 10) operates through the lateral member 320 including a second non-conductive portion (e.g., the second non-conductive portion 3222 in FIG. 10), a beam form of vertical polarization (V-pol) may be distorted by a conductive sheet 3011 (e.g., a Cu sheet) disposed on a rear surface of a display 301 (e.g., a display panel). According to an embodiment of the disclosure, in order to suppress such a beam form distortion of vertical polarization, the electronic device 300 may include at least one conductive connection member 3212 disposed between a conductive portion 321 of the lateral member 320 and the conductive sheet 3011. According to an embodiment, the conductive connection member 3212 may be disposed to be in physical contact with both the conductive sheet 3011 and the conductive portion 321 of the lateral member 320. According to an embodiment, the conductive connection member 3212 may be formed of a metal member. Thus, the conductive sheet 3011 electrically connected to the conductive member 321 through the conductive connection member 3212 may be seen as at least a part of the conductive member 321 disposed near the antenna module 500.
According to various embodiments, the antenna module 500 may be configured to allow vertical polarization (V-pol) to be adjusted independently without substantial change of horizontal polarization (H-pol) through a movement of the conductive connection member 3212 between the conductive sheet 3011 and the lateral member 320.
FIG. 14A is a radiation pattern view showing horizontal polarization (H-pol) of an antenna module before and after a movement of a conductive connection member according to an embodiment of the disclosure.
Referring to FIG. 14A, even if the conductive connection member 3212 is moved between the conductive sheet 3011 and the lateral member 320, horizontal polarization 1402 after movement may be exhibited at the same position as horizontal polarization 1401 before movement. This means that even when the conductive connection member 3212 is moved, the horizontal polarization (H-pol) may be substantially fixed.
FIG. 14B is a radiation pattern view showing vertical polarization (V-pol) of an antenna module before and after a movement of a conductive connection member according to an embodiment of the disclosure.
As shown in FIG. 13, when the conductive connection member 3212 is moved from a first position (P1) to a second position (P2) between the conductive sheet 3011 and the lateral member 320, vertical polarization (V-pol) may be adjusted. Referring to FIG. 14B, vertical polarization 1403 in case where the conductive connection member 3212 of FIG. 13 is not applied, vertical polarization 1404 before movement of the conductive connection member 3212 of FIG. 13, and vertical polarization 1405 after the movement are all different from each other. This may mean that independent tuning of vertical polarization (V-pol) is possible depending on the presence and/or movement of the conductive connection member 3212.
FIG. 15 is a perspective view partially showing an electronic device including a conductive sheet having a notch according to an embodiment of the disclosure.
Referring to FIG. 15, when the antenna module (e.g., the antenna module 500 in FIG. 10) operates through the lateral member 320 in the electronic device including the second non-conductive portion 3222 and the conductive connection member 3212 as described above in FIG. 13, the sensitivity may be degraded by the conductive sheet 3011 (e.g., a Cu sheet) disposed on the rear surface of the display 301. In order to prevent such a degradation of sensitivity, the electronic device 300 may include, for example, a notch 3012 formed in at least a part of the conductive sheet 3011. According to an embodiment, the notch 3012 may have a region overlapped with the second non-conductive area 3222 when the front plate 302 is viewed from above. According to an embodiment, in the inner space 3001 of the electronic device 300, the antenna module (e.g., the antenna module 500 in FIG. 10) may form a beam pattern in the direction of the display 301 through the second non-conductive portion 3222 formed in the lateral member 320 and the notch 3012 formed in the conductive sheet 3011.
FIG. 16 is a graph showing radiation patterns by vertical polarization (V-pol) and horizontal polarization (H-pol) of an antenna module (e.g., the antenna module 500 in FIG. 10) disposed in the electronic device of FIG. 15 according to an embodiment of the disclosure.
Referring to FIG. 16, in the antenna module (e.g., the antenna module 500 in FIG. 10), vertical polarization 1602 in case where a notch region (e.g., the notch 3012 in FIG. 15) is applied to a conductive sheet (e.g., the conductive sheet 3011 in FIG. 15) exhibits a relatively excellent sensitivity characteristic compared to vertical polarization 1601 in case where the notch region is not applied. In addition, horizontal polarization 1604 in case where the notch region is applied to the conductive sheet exhibits a relatively excellent sensitivity characteristic compared to horizontal polarization 1603 in case where the notch region is not applied.
FIG. 17 is a cross-sectional view partially showing an electronic device according to an embodiment of the disclosure.
According to a certain embodiment, it is possible to prevent the performance degradation of the antenna module 500 by changing the structural shape of the inner surface of the conductive portion 321 of the lateral member 320.
Referring to FIG. 17, the electronic device 300 may include the conductive portion 321 disposed as a part of the lateral member 320 near one upper side of the antenna module 500 placed in the inner space 3001, and supporting at least in part the front plate 302 and the display 301. According to an embodiment, in the lateral member 320, a typical shape of the conductive portion 321 such as a first-stage structure (e.g., a first-stage eaves structure) or a stepped structure (e.g., a two-stage eaves structure) is changed to increase (delay with 180 degrees) or decrease a phase difference between radio waves directly radiated to the outside from the antenna module 500 and radio waves reflected by the inner surface of the conductive portion 321. As a result, it is possible to prevent the cancellation phenomenon (or null phenomenon) occurring when radio waves having different phases gather around one place.
According to various embodiments, the conductive portion 321 of the lateral member 320 may include a structural shape for not only distorting an effective direction of radio waves radiated from the antenna module 500 and reflected by the conductive portion 321, but also increasing a path length. According to an embodiment, the conductive portion 321 may include a first flat plane 3203, a curved plane 3204 extended laterally from the first flat plane 3203, and a second flat plane 3205 extended from the curved plane 3204. According to an embodiment, the first flat plane 3203 and/or the second flat plane 3205 may be formed to be substantially perpendicular to the first surface 591 of the PCB 590. In another embodiment, the first flat plane 3203 and/or the second flat plane 3205 may be formed to have various inclination angles that allow radio waves (E) radiated from the antenna module 500 and reflected by the conductive portion 321 to be scattered without gathering around one place. In still another embodiment, the curved plane 3204 may be formed to have various radii of curvature that allow the radio waves (E) radiated from the antenna module 500 and reflected by the conductive portion 321 to be scattered without gathering around one place. In yet another embodiment, the conductive portion 321 may have, at least in part, a thickness (t) adjusted to increase the path length of the radio waves (E) radiated from the antenna module 500.
FIG. 18 is a cross-sectional view partially showing an electronic device according to an embodiment of the disclosure.
FIGS. 19A and 19B are perspective views partially showing a support member according to various embodiments of the disclosure.
An electronic device 600 of FIG. 18 may be similar, at least in part, to the electronic device 101 of FIG. 1, the electronic device 300 of FIG. 3A, or the electronic device 300 of FIG. 10, or may include other embodiments of the electronic device.
Referring to FIGS. 18 and 19A, the electronic device 600 may include a housing 610 (e.g., the housing 310 in FIG. 10) that includes a front cover 602 (e.g., the front plate 302 in FIG. 10), a rear cover 611 (e.g., the rear plate 311 in FIG. 10) facing a direction opposite to the front cover 602, and a support member 620 (e.g., the lateral member 320 in FIG. 10) surrounding an inner space 6001 between the front cover 602 and the rear cover 611. According to an embodiment, the electronic device 600 may include a device substrate 640 (e.g., the PCB 340 in FIG. 3C) disposed in the inner space 6001. According to an embodiment, the support member 620 may include a conductive first portion 621 forming a lateral appearance (e.g., the lateral surface 310c in FIG. 3A) of the electronic device 600, a second portion 622 adjacent to an array antenna AR1, the front cover 602, and the conductive first portion 621 and having at least one opening 6221 filled with a non-conductive material, and a third portion 623 formed of a non-conductive material and adjacent to the array antenna AR1, the rear cover 611, and the conductive first portion 621. According to an embodiment, the support member 620 may be disposed between the front and rear covers 602 and 611, support a display 601 of the electronic device 600, and extended toward the lateral surface of the electronic device 600 to form, at least in part, the lateral appearance (e.g., the lateral surface 310c in FIG. 3A) of the electronic device 600.
According to various embodiments, the front cover 602 may be disposed through at least parts of the conductive first portion 621 and the second portion 622 of the support member 620. According to an embodiment, the front cover 602 may be supported through an extended portion 6211 (e.g., the first support member 3211 in FIG. 10) extended from the support member 620. According to an embodiment, the electronic device 600 may include the display 601 disposed between the front cover 602 and the support member 620 to be seen from the outside at least in part through the front cover 602.

According to an embodiment, the display 601 may include the conductive sheet 6011 (e.g., a Cu sheet) disposed for noise shielding on the rear surface of the display panel.
According to various embodiments, the antenna module 500 may be disposed in a direction perpendicular to the front cover 602 in the inner space 6001 of the electronic device 600 through the conductive member 550. According to an embodiment, the antenna module 500 may be mounted such that the array antenna AR1 including conductive patches (e.g., the conductive patches 510, 520, 530, and 540 in FIG. 5A) (e.g., a plurality of antenna elements) face the support member 620. For example, the antenna module 500 may be disposed such that the first surface 591 of the PCB 590 faces the support member 620, and thus a beam pattern may be formed in a direction (denoted by {circle around (1)}) faced by the support member 620 of the electronic device 600.
According to various embodiments, the conductive first portion 621 and the second portion 622 of the support member 620 may be formed in a shape for supporting the display 601 and the front cover 602 near one upper side of the antenna module 500. According to an embodiment, the third portion 623 of the support member 620 may be formed in a shape for supporting the rear cover 611 near one lower side of the antenna module 500. According to an embodiment, the conductive first portion 621 may be exposed at least in part to the outside of the electronic device 600, and the second and third portions 622 and 623 may be hidden by the front and rear covers 602 and 611 so as not to be exposed to the outside. According to an embodiment, a beam formed by the array antenna AR1 may be radiated to the outside through the at least one opening 6221 and the third portion 623.
According to various embodiments, the at least one opening 6221 formed in the second portion 622 may be filled with a non-conductive material. For example, the non-conductive material of the second portion 622 and the non-conductive material of the third portion 623 may be inserted-injected together with the conductive first portion 621. In a certain embodiment, the non-conductive material of the second portion 622 and the non-conductive material of the third portion 623 may be formed of insulating materials having the same or different properties (e.g., different dielectric constants). In a certain embodiment, the non-conductive material of the second portion 622 and the non-conductive material of the third portion 623 may be connected to or spaced apart from each other in the inner space of the electronic device. In a certain embodiment, the at least one opening 6221 may be an empty space in which no insulating material is disposed. According to an embodiment, the second portion 622 may include a flat portion 6201 and a curved portion 6202 extended from the flat portion 6201 to the first portion 621.

According to an embodiment, the at least one opening 6221 may be disposed at a position overlapped at least in part with the array antenna AR1 when the front cover 602 is viewed from above and/or when the support member 620 is viewed from outside. According to an embodiment, a plurality of openings 6221 may be disposed at positions corresponding to respective conductive patches (e.g., the first conductive patch 510, the second conductive patch 520, the third conductive patch 530, and/or the fourth conductive patch 540 in FIG. 5). Therefore, a beam pattern radiated from the antenna module 500 in the direction (denoted by {circle around (1)}) of the support member 620 is increased upward in radiation length up to the conductive sheet 6011 of the display 601 through the at least one opening 6221. This may help to reduce the cancellation phenomenon as compared to an antenna module disposed through the support member 620 having no opening 6221.
Referring to FIG. 19B, the support member 620 may include a single opening 6221 disposed to be overlapped with the array antenna AR1. According to an embodiment, the opening 6221 may be formed in a size overlapped with all of a plurality of conductive patches (e.g., the first conductive patch 510, the second conductive patch 520, the third conductive patch 530, and/or the fourth conductive patch 540 in FIG. 5) of the array antenna AR1 when the front cover 602 is viewed from above and/or when the support member 620 is viewed from outside. Although not shown, the electronic device 600 may include, as in FIG. 13, an electrical connection member (e.g., the electrical connection member 3212 in FIG. 20A) disposed between the conductive first portion 621 and the conductive sheet 6011. In addition, the radiation characteristics of the array antenna AR1 may be adjusted depending on a change in position of the conductive connection member.

Referring to FIGS. 20A and 20B, when the beam pattern of the array antenna AR1 is formed through the at least one opening 6221 shown in FIG. 18, the sensitivity may be degraded by the conductive sheet 6011 (e.g., a Cu sheet) disposed on the rear surface of the display 601. In order to prevent such a degradation of sensitivity, the electronic device 600 may include, for example, at least one slot 6011a or 6011b formed in at least a part of the conductive sheet 6011. According to an embodiment, the at least one slot 6011a or 6011b may be formed at a position overlapped with the at least one opening 6221 when the front cover 602 is viewed from above. For example, the at least one slot 6011a or 6011b may be one slot 6011a or two slots 6011b having a length overlapped with a plurality of antenna elements (e.g., conductive patches) of the array antenna AR1. In a certain embodiment, the at least one slot may be a plurality of slots respectively corresponding to the plurality of antenna elements.
