Description

Technical Field

[0001] The present invention relates to an electronic device, and more particularly to an electronic device having an antenna module for wirelessly receiving data. Background Art

[0002] As image technology changes from analog to digital, in order to provide images that are closer to the actual screen, it has developed from SD (Standard-Definition) to HD (Hi-Definition). SD supports a resolution of 704×480 and is composed of about 350,000 pixels. HD is divided into HD and Full HD (Full HD). Among them, Full HD, which supports a higher resolution, supports a resolution of 1920×1080 and is composed of 2 million pixels. Therefore, compared with the above SD, it provides significantly higher quality images.

[0003] Image technology in recent years has surpassed Full HD and further grown into UHD (Ultra High-Definition), which has attracted much attention as a new generation of media environment that supports ultra-high image quality and ultra-high resolution. UHD supports 4K (3840×2160) and 8K (7680×4320) resolutions, as well as surround audio with a maximum of 22.2 channels. As described above, UHD provides four times clearer image quality than HD, even with 4K UHD as the benchmark, and in the case of 8K UHD, it provides 16 times clearer image quality than HD.

[0004] In recent years, wireless display systems have emerged that wirelessly transmit such high-resolution images to a display device.

[0005] The wireless display system is a system that transmits and receives A / V data between an A / V transmitting device and an A / V receiving device through a local area network.

[0006] The A / V receiving device displays the A / V data received from the A / V transmitting device.

[0007] An example of the A / V transmission device is a transmission box having an antenna module for wirelessly transmitting A / V data.

[0008] An example of the A / V receiving device may be a display device having an antenna module for receiving A / V data transmitted from an A / V transmitting device and outputting the received A / V data.

[0009] The display device may include a pair of antenna modules and an IR module disposed between the pair of antenna modules, and the pair of antenna modules may be spaced apart from each other on the left and right.

[0010] In a wireless display system, the antenna module of the A / V transmitting device can be located on the left or right side of the display device. In this case, a pair of antenna modules arranged on the display device can receive data sent from the antenna module of the A / V transmitting device in a dual-stream manner, and the display device can output an image.

[0011] When the A / V transmission device is disposed on the left or right side of the display device, one of the pair of antenna modules of the display device is blocked by the IR module and cannot receive data, and the display device can operate in a single-stream manner.

[0012] When operating in a single-stream mode, the compression rate needs to be doubled compared to the case of dual-stream mode in order to send and receive data at the same level as in the dual-stream mode. However, when the compression rate is increased, the image quality level may be reduced. Summary of the invention

[0166] On the other hand, the first antenna structure and the second antenna structure configured in the electronic device can be formed into a multi-layer substrate structure. The first antenna structure and the second antenna structure can be implemented as a PCB (printed circuit board) structure. In this regard, Figure 8a and Figure 8b Shown in Figure 5 (a) is a cross-sectional view of the first antenna structure and the second antenna structure implemented in the first PCB and the second PCB of the antenna configuration structure. Figure 8c and Figure 8d Shown in Figure 5 (b) is a cross-sectional view of the first antenna structure and the second antenna structure implemented in the first PCB and the second PCB of the antenna configuration structure.

[0167] Figure 8a (a) shows the configuration as Figure 5 1 and 10.

The antenna configuration structure of (b) is implemented as a cross-sectional view of a second antenna structure 1000b on a second PCB 1010b. Figure 8d (b) shows a three-dimensional structure of the second PCB 1010b formed by the first surface BS1 and the second surface BS2 to the fifth surface BS5.

[0171] Relatedly, Figures 8a to 8dThe first antenna structure and the second antenna structure may be connected with Figure 7a The first antenna structure 1000a corresponds to the second antenna structure 1000b. Therefore, Figures 8a to 8d In the first antenna structure and the second antenna structure, the array antennas arranged on the front and side surfaces operate as horizontally polarized antennas, and the plurality of array antennas arranged on the bottom surface operate as horizontally or vertically polarized antennas.

[0172] Reference Figures 4 to 7a , Figure 8a as well as Figure 8c , the first antenna structure 1000a may include a first PCB 1010a, a first array antenna 1200a, a second array antenna 1300a, and a first wireless communication IC 1400a forming a multilayer structure. In addition, the first antenna structure 1000a may also include a third array antenna 1100a formed on the left side and a fourth array antenna 1100b formed on the right side. A plurality of ground layers 1110g, 1120g may be disposed inside the first PCB 1010a, so that the interference between the signals of the plurality of array antennas can be kept below a preset level.

[0173] The first PCB 1010a may form a plurality of side surfaces. The first PCB 1010a may include a first surface BS1 to a fifth surface BS5. The first surface BS1 among the plurality of side surfaces may be formed to face the front direction D1 of the electronic device 200, and the second surface BS2 among the plurality of side surfaces may be formed to face the back direction D2 of the electronic device 200. The third surface BS3 among the plurality of side surfaces may be formed to face the left side direction of the electronic device 200, and the fourth surface BS4 among the plurality of side surfaces may be formed to face the right side direction of the electronic device 200. The fifth surface BS5 among the plurality of side surfaces may be formed to face the bottom direction D5 of the electronic device 200.

[0174] First surface BS1 may be formed to face first direction (front direction) D1. Second surface BS2 may be formed to face second direction (back direction) D2 opposite to first direction D1. Third to fifth surfaces BS3 to BS5 may be formed to surround a space between first surface BS1 and second surface BS2.

[0175] A first array antenna 1200a may be configured on the first surface BS1 located between the third surface BS3 and the fourth surface BS4. A second array antenna 1300a may be configured on the fifth surface BS5 located between the third surface BS3 and the fourth surface BS4. The first array antenna 1200a may form a beam pattern toward the first direction D1. The second array antenna 1300a may form a beam pattern toward the fifth direction D5. A first wireless communication IC 1400a may be configured on the second surface BS2. The first wireless communication IC 1400a may send or receive wireless signals in a first frequency range.

[0176] Reference Figures 4 to 6 , Figure 7b , Figure 8b as well as Figure 8d The second antenna structure 1000b forming a multilayer structure may include a second PCB 1010b, a fifth array antenna 1200b, a sixth array antenna 1300b, and a second wireless communication IC 1400b. In addition, the second antenna structure 1000b may also include a seventh array antenna 1100c formed on the left side and an eighth array antenna 1100d formed on the right side. A plurality of ground layers 1110g and 1120g may be disposed inside the second PCB 1010b, so that the interference between the signals of the plurality of array antennas can be kept below a preset level.

[0177] The second PCB 1010b may form a plurality of side surfaces. The second PCB 1010b may include a first surface BS1 to a fifth surface BS5. The first surface BS1 of the plurality of side surfaces may be formed to face the front direction D1 of the electronic device 200, and the second surface BS2 of the plurality of side surfaces may be formed to face the back direction D2 of the electronic device 200. The third surface BS3 of the plurality of side surfaces may be formed to face the left side direction of the electronic device 200, and the fourth surface BS4 of the plurality of side surfaces may be formed to face the right side direction of the electronic device 200. The fifth surface BS5 of the plurality of side surfaces may be formed to face the bottom direction D5 of the electronic device 200.

[0178] First surface BS1 may be formed to face first direction (front direction) D1. Second surface BS2 may be formed to face second direction (back direction) D2 opposite to first direction D1. Third to fifth surfaces BS3 to BS5 may be formed to surround a space between first surface BS1 and second surface BS2.

[0179] A fifth array antenna 1200b may be configured on the first surface BS1 between the third surface BS3 and the fourth surface BS4. A sixth array antenna 1300b may be configured on the fifth surface BS5 between the third surface BS3 and the fourth surface BS4. The fifth array antenna 1200b may form a beam pattern toward the first direction D1. The sixth array antenna 1300b may form a beam pattern toward the fifth direction D5. A second wireless communication IC 1400b may be configured on the second surface BS2. The second wireless communication IC 1400b may send or receive wireless signals in the first frequency range.

[0180] The polarization of the first array antenna 1200a may be formed to be the same as the polarization of the fifth array antenna 1200b. The first array antenna 1200a may radiate a polarized signal that is polarized in the Y-axis direction and advances in the X-axis direction. The fifth array antenna 1200b may radiate a polarized signal that is polarized in the Y-axis direction and advances in the X-axis direction.

[0181] For a signal moving in the X-axis direction as the front direction, if polarization is formed in the Y-axis direction, it is equivalent to a horizontally polarized signal, and if polarization is formed in the Z-axis direction, it is equivalent to a vertically polarized signal. Therefore, the first array antenna 1200a and the fifth array antenna 1200b can radiate a horizontally polarized signal in the Y-axis direction. The horizontally polarized signal can be a signal that forms an electric field along the Y-axis direction corresponding to the length of the first antenna structure 1000a.

[0182] The polarization of the third array antenna 1100a may be formed to be the same as the polarization of the fourth array antenna 1100b. The third array antenna 1100a may radiate a polarized signal that is polarized in the X-axis direction and advances in the Y-axis direction on the left. The fourth array antenna 1100b may radiate a polarized signal that is polarized in the X-axis direction and advances in the Y-axis direction on the right.

[0183] For a signal moving in the Y-axis direction as the lateral direction, if polarization is formed in the X-axis direction, it is equivalent to a horizontally polarized signal, and if polarization is formed in the Z-axis direction, it is equivalent to a vertically polarized signal. Therefore, the third array antenna 1100a and the fourth array antenna 1100b can radiate horizontally polarized signals in the X-axis direction.

[0184] The polarization of the second array antenna 1300a may be formed to be different from the polarization of the sixth array antenna 1300b. The polarization of the second array antenna 1300a may be formed to be orthogonal to the polarization of the sixth array antenna 1300b. The second array antenna 1300a may radiate a polarized signal that is polarized in the Y-axis direction and advances in the Z-axis direction of the lower portion. The sixth array antenna 1300b may radiate a polarized signal that is polarized in the X-axis direction and advances in the Z-axis direction of the lower portion.

[0185] For a signal moving in the Z-axis direction, if polarization is formed in the Y-axis direction, it is equivalent to a horizontally polarized signal, and if polarization is formed in the X-axis direction, it is equivalent to a vertically polarized signal. Therefore, the second array antenna 1300a can radiate a horizontally polarized signal in the Y-axis direction. The sixth array antenna 1300b can radiate a vertically polarized signal in the X-axis direction. As another example, the second array antenna 1300a can radiate a vertically polarized signal, and the sixth array antenna 1300b can radiate a horizontally polarized signal.

[0186] The polarization of the seventh array antenna 1100c can be formed to be the same as the polarization of the eighth array antenna 1100d. The seventh array antenna 1100c can radiate a polarized signal that is polarized in the X-axis direction and advances in the Y-axis direction on the left. The eighth array antenna 1100d can radiate a polarized signal that is polarized in the X-axis direction and advances in the Y-axis direction on the right. Therefore, the seventh array antenna 1100c and the eighth array antenna 1100d can radiate a horizontally polarized signal in the X-axis direction.

[0187] The communication device 100 that transmits and receives wireless signals with the electronic device 200 may radiate horizontal polarization signals. When the communication device 100 is located in the front area or the side area of ​​the electronic device 200, both the first antenna structure 1000a and the second antenna structure 1000b may operate. On the other hand, when the communication device 100 is located in the lower area of ​​the electronic device 200, either the first antenna structure 1000a or the second antenna structure 1000b may operate.

[0188] When the communication device 100 is located in the front area of ​​the electronic device 200, the plurality of array antennas 1200a and 1200b located in the front part of each of the first antenna structure 1000a and the second antenna structure 1000b that can operate in co-polarization both operate and communicate simultaneously. The co-polarization may be either horizontal polarization or vertical polarization on the bottom surface in the front communication area.

[0189] When the communication device 100 is located in the left side area of ​​the electronic device 200, it communicates with the antennas capable of operating in co-polarization located on the left side parts of the first antenna structure 1000a and the second antenna structure 1000b. The co-polarization may be either horizontal polarization or vertical polarization on the bottom surface of the side communication area.

[0190] When the communication device 100 is located in the right side area of ​​the electronic device 200, communication is performed simultaneously with the antenna capable of operating in co-polarization located in the right side portion of each of the first antenna structure 1000a and the second antenna structure 1000b. The co-polarization may be either horizontal polarization or vertical polarization on the bottom surface of the side communication area.

[0191] Therefore, when the communication device 100 is located on one side of the left and right side regions of the electronic device 200, the plurality of array antennas located on the corresponding side of the first antenna structure 1000a and the second antenna structure 1000b can all operate. On the other hand, when the communication device 100 is located in the lower region of the electronic device 200, any one of the plurality of array antennas 1300a and 1300b located on the bottom surface of the first antenna structure 1000a and the second antenna structure 1000b operates.

[0192] In this regard, when the communication device 100 is located in the lower area of ​​the electronic device 200, the communication device 100 can communicate with any one of the first antenna structure 1000a and the second antenna structure 1000b that can operate with different polarizations. When the communication device 100 is located at a position that provides polarization horizontal to the wall, the first antenna structure 1000a may provide co-polarization. In this case, the antenna of the communication device 100 communicates with the first antenna structure 1000a of the electronic device 200. The communication device 100 cannot communicate with the second antenna structure 1000b of the electronic device 200.

[0193] When the communication device 100 is located in the lower area of ​​the electronic device 200, it can communicate with either the first antenna structure 1000a or the second antenna structure 1000b that can operate with different polarizations. When the communication device 100 is located at a position that provides polarization perpendicular to the wall, the second antenna structure 1000b may provide co-polarization. In this case, the antenna of the communication device 100 communicates with the second antenna structure 1000b of the electronic device 200. The communication device 100 cannot communicate with the first antenna structure 1000a of the electronic device 200.

[0194] When the communication device 100 is located in the front area, the plurality of patch array antennas on the front of each of the first antenna structure 1000a and the second antenna structure 1000b can radiate polarized signals capable of communicating with the communication device 100. The polarized signal can be one of horizontal polarization and vertical polarization.

[0195] When the communication device 100 is located in the side area, the plurality of antennas on one side of the side array antennas of the first antenna structure 1000a and the second antenna structure 1000b can radiate polarized signals capable of communicating with the communication device 100. The polarized signal can be one of horizontal polarization and vertical polarization.

[0196] When the communication device 100 is located in the lower area, the first wireless communication IC 1400 a may be controlled to receive and transmit horizontal polarization signals through the second array antenna 1300 a of the first antenna structure 1000 a .

[0197] When the communication device 100 is located in the lower area, the second wireless communication IC 1400b may receive or transmit a vertical polarization signal through the sixth array antenna 1300b of the second antenna structure 1000b.

[0198] On the other hand, the first antenna structure and the second antenna structure of the electronic device of the present specification may be configured in different areas of the PCB.

[0262] For a signal moving in the X-axis direction, which is the front direction, if polarization is formed in the Y-axis direction, it is equivalent to a horizontally polarized signal, and if polarization is formed in the Z-axis direction, it is equivalent to a vertically polarized signal. Therefore, the first array antenna 1200c can radiate a vertically polarized signal in the Z-axis direction, and the fifth array antenna 1200d can radiate a horizontally polarized signal in the Y-axis direction. The horizontally polarized signal is a signal that forms an electric field in the Y-axis direction corresponding to the length of the third antenna structure 1000c, and the vertically polarized signal is a signal that forms an electric field in the Z-axis direction corresponding to the width of the third antenna structure 1000c.

[0263] The polarization of the third array antenna 1100e may be formed to be the same as the polarization of the fourth array antenna 1100f. The third array antenna 1100e may radiate a polarized signal that is polarized in the Z-axis direction and advances in the Y-axis direction on the left. The fourth array antenna 1100f may radiate a polarized signal that is polarized in the Z-axis direction and advances in the Y-axis direction on the right.

[0264] If a signal moving in the Y-axis direction, which is the lateral direction, is polarized in the Z-axis direction, it is equivalent to a vertically polarized signal. Therefore, the third array antenna 1100e and the fourth array antenna 1100f can radiate vertically polarized signals in the Z-axis direction.

[0265] The polarization of the second array antenna 1300c may be formed to be different from the polarization of the sixth array antenna 1300d. The polarization of the second array antenna 1300c may be formed to be orthogonal to the polarization of the sixth array antenna 1300d. The second array antenna 1300c may radiate a polarized signal that is polarized in the Y-axis direction and advances in the Z-axis direction of the lower portion. The sixth array antenna 1300d may radiate a polarized signal that is polarized in the X-axis direction and advances in the Z-axis direction of the lower portion.

[0266] For a signal moving in the Z-axis direction, if polarization is formed in the Y-axis direction, it is equivalent to a horizontally polarized signal, and if polarization is formed in the X-axis direction, it is equivalent to a vertically polarized signal. Therefore, the second array antenna 1300c can radiate a horizontally polarized signal in the Y-axis direction. The sixth array antenna 1300d can radiate a vertically polarized signal in the X-axis direction. As another example, the second array antenna 1300c can radiate a vertically polarized signal, and the sixth array antenna 1300d can radiate a horizontally polarized signal.

[0267] The polarization of the seventh array antenna 1100g can be formed to be the same as the polarization of the eighth array antenna 1100h. The seventh array antenna 1100g can radiate a polarized signal that is polarized in the Z-axis direction and advances in the Y-axis direction on the left. The eighth array antenna 1100h can radiate a polarized signal that is polarized in the Z-axis direction and advances in the Y-axis direction on the right. Therefore, the seventh array antenna 1100g and the eighth array antenna 1100h can radiate vertically polarized signals in the Z-axis direction.

[0268] The communication device 100 that transmits and receives wireless signals with the electronic device 200 may radiate horizontally polarized signals. When the communication device 100 is located in the front area or the side area of ​​the electronic device 200, both the third antenna structure 1000c and the fourth antenna structure 1000d may operate. On the other hand, when the communication device 100 is located in the lower area of ​​the electronic device 200, either the third antenna structure 1000c or the fourth antenna structure 1000d may operate.

[0269] When the communication device 100 is located in the front area of ​​the electronic device 200, the plurality of array antennas 1200c and 1200d located in the front part of each of the third antenna structure 1000c and the fourth antenna structure 1000d that can operate in co-polarization both operate and communicate simultaneously. The co-polarization may be either horizontal polarization or vertical polarization on the bottom surface in the front communication area.

[0270] When the communication device 100 is located in the left side area of ​​the electronic device 200, communication is performed simultaneously with the antennas capable of operating in co-polarization located on the left side parts of the third antenna structure 1000c and the fourth antenna structure 1000d. The co-polarization may be either horizontal polarization or vertical polarization on the bottom surface in the side communication area.

[0271] When the communication device 100 is located in the right side area of ​​the electronic device 200, it communicates with the antennas capable of operating in co-polarization located on the right side parts of the third antenna structure 1000c and the fourth antenna structure 1000d. The co-polarization may be either horizontal polarization or vertical polarization on the bottom surface in the side communication area.

[0272] Therefore, when the communication device 100 is located on one side of the left and right side regions of the electronic device 200, the plurality of array antennas located on the corresponding sides of the third antenna structure 1000c and the fourth antenna structure 1000d can all operate. On the other hand, when the communication device 100 is located in the lower region of the electronic device 200, any one of the plurality of array antennas 1300c and 1300d located on the bottom surfaces of the third antenna structure 1000c and the fourth antenna structure 1000d operates.

[0273] In this regard, when the communication device 100 is located in the lower area of ​​the electronic device 200, the communication device 100 can communicate with either of the third antenna structure 1000c and the fourth antenna structure 1000d that can operate with different polarizations. When the communication device 100 is located at a position that provides polarization horizontal to the wall, the third antenna structure 1000c can provide co-polarization. In this case, the antenna of the communication device 100 communicates with the third antenna structure 1000c of the electronic device 200. The communication device 100 cannot communicate with the fourth antenna structure 1000d of the electronic device 200.

[0274] When the communication device 100 is located in the lower area of ​​the electronic device 200, it can communicate with either the third antenna structure 1000c or the fourth antenna structure 1000d that can operate with different polarizations. When the communication device 100 is located at a position that provides polarization perpendicular to the wall, the fourth antenna structure 1000d may provide co-polarization. In this case, the antenna of the communication device 100 communicates with the fourth antenna structure 1000d of the electronic device 200. The communication device 100 cannot communicate with the third antenna structure 1000c of the electronic device 200.

[0275] When the communication device 100 is located in the front area, the plurality of patch array antennas on the front of the third antenna structure 1000c and the fourth antenna structure 1000d can radiate polarized signals that can communicate with the communication device 100. The polarized signal can be one of horizontal polarization and vertical polarization.

[0276] When the communication device 100 is located in the side area, the plurality of antennas on one side of the side array antennas of the third antenna structure 1000c and the fourth antenna structure 1000d can radiate polarized signals capable of communicating with the communication device 100. The polarized signal can be one of horizontal polarization and vertical polarization.

[0277] When the communication device 100 is located in the lower area, the first wireless communication IC 1400c may be controlled to receive and transmit horizontal polarization signals through the second array antenna 1300c of the third antenna structure 1000c.

[0278] The communication device 100 may be located in the lower area, and the second wireless communication IC 1400d may receive or transmit a vertically polarized signal through the sixth array antenna 1300d of the fourth antenna structure 1000d.

The vertically polarized signal of the communication device 100b2 in the second rotation state and the horizontally polarized signal of the second array antenna 1300c have cross-polarizations that are orthogonal to each other. Therefore, the wireless communication performance between the communication device 100b in the second rotation state and the third antenna structure 1000c is reduced or may be in a state where communication is impossible.

[0328] In the above, an electronic device provided with a first antenna structure and a second antenna structure having a plurality of array antennas is described. In this regard, a method for performing wireless communication between an electronic device and a communication device is described in detail with reference to the accompanying drawings.

[0329] Relatedly, Fig.14 1 is a flowchart showing the operation of the electronic device of the present specification for transmitting and receiving A / V signals with the communication device. Fig.14 , a method for the electronic device 200 of this specification to receive or send wireless signals through a plurality of array antennas of a first antenna structure and a second antenna structure is described.

[0330] Reference Figures 5 to 14 , the method of changing or restoring the A / V signal transceiver beam of this specification is described. When the power of the communication device 100 and the electronic device 200 included in the wireless display system is turned on (S11), the electronic device 200 can identify the device ID of the communication device 100 (S12). The electronic device 200 can search for the configuration position and rotation state of the communication device 100 (S13).

[0331] It may be determined based on the device ID whether the communication device 100 provides dual polarization (S14). It may be determined whether the plurality of antenna elements of the communication device 100 are capable of transmitting and receiving horizontally polarized signals and vertically polarized signals.

[0332] It is possible to search in which area of ​​the front area, the lower area, the one side area, and the other side area of ​​the electronic device 200 the communication device 100 is configured. Thus, the electronic device 200 can determine whether the communication device 100 is configured in the lower area of ​​the electronic device 200 (S15). When the communication device 100 provides dual polarization, it is possible to determine whether the communication device 100 is configured in the front area or the lower area of ​​the electronic device 200 (S16).

[0333] When the communication device 100 provides single polarization and the communication device 100 is configured in the lower area of ​​the electronic device 200, a 1T1R operation (S21) can be performed by any one of the first antenna structure 1000a and the second antenna structure 1000b. Thus, horizontal polarization signals can be sent and received by the second array antenna 1300a of the first antenna structure 1000a. Alternatively, vertical polarization signals can be sent and received by the sixth array antenna 1300b of the second antenna structure 1000b. Therefore, the communication device 100 and the electronic device 200 can perform a 1T1R operation by any one of the first antenna structure 1000a and the second antenna structure 1000b.

[0334] When the communication device 100 provides single polarization and the communication device 100 is configured in the front area, one side area or the other side area of ​​the electronic device 200, a diversity operation (S22) can be performed through the first antenna structure 1000a and the second antenna structure 1000b. Thus, a diversity operation of transmitting or receiving a co-polarized signal can be performed through the first antenna structure 1000a and the second antenna structure 1000b.

[0335] When the communication device 100 provides dual polarization and is disposed in a front area or a lower area of ​​the electronic device 200 , it may be controlled so that both the first antenna structure 1000 a and the second antenna structure 1000 b operate.

[0336] When the seventh array antenna 1100c and the eighth array antenna 1100d provide vertical polarization (S17, "Yes"), a 2T2R operation can be performed by the first antenna structure 1000a and the second antenna structure 1000b (S23). Thus, the 2T2R operation can be performed by a multiple input multiple output (MIMO) operation of simultaneously sending or receiving vertical polarization signals and horizontal polarization signals.

[0337] When the seventh array antenna 1100c and the eighth array antenna 1100d do not provide vertical polarization (S17, "No"), a 1T2R operation can be performed through the first antenna structure 1000a and the second antenna structure 1000b (S24). Therefore, the communication device 100 and the electronic device 200 can perform a 1T2R operation through any one of the first antenna structure 1000a and the second antenna structure 1000b.

[0338] On the other hand, the electronic device of the present specification can appropriately select a plurality of array antennas of the first antenna structure and the second antenna structure based on the location of the communication device, and receive the A / V signal through optimal beamforming. In this regard, Fig.15 A flowchart of a method for an electronic device of the present specification to select, change or restore a wireless beamforming signal for transmitting and receiving an A / V signal is shown.

[0339] Can be Fig.14 After selecting / changing the operation mode of multiple array antennas, execute Fig.15 The beam selection, change or recovery process of, but not limited to, Fig.15 During the wireless communication, when the configuration area of ​​the communication device is changed, the beam selection, change or recovery process is performed. Fig.14 The operation mode of the array antenna.

[0340] Reference Figure 1 , Figure 2 , Figures 5 to 15, a method for selecting, changing or restoring a wireless beamforming signal for transmitting and receiving an A / V signal by an electronic device is described. The processor 290 can retrieve a beam that can be formed between the communication device 100 and the electronic device 200 (S111). The processor 290 can obtain all beams that can be formed between the communication device 100 and the electronic device 200 as a search result. On the other hand, all beams may include a pair of beams consisting of a transmission beam for transmitting an A / V signal at the communication device 100 and a reception beam for receiving an A / V signal at the electronic device 200.

[0341] In addition, the processor 290 may obtain an effective beam among the beams that are retrieved as being able to be formed between the communication device 100 and the electronic device 200 (S112). The effective beam may be at least one beam that is actually selected for transmitting and receiving A / V signals among all the beams retrieved by the processor 290. Alternatively, the effective beam may be at least one beam that is able to transmit and receive A / V signals at a minimum transmission speed or above among the beams that are able to be formed between the communication device 100 and the electronic device 200.

[0342] In addition, the processor 290 may acquire a beam angle based on a beam ID (S113). The beam ID may be an ID for identifying each of the beams formed between the communication device 100 and the electronic device 200. The beam angle may include a beam reception angle as an angle on the electronic device 200 side and a beam transmission angle as an angle on the communication device 100 side. The beam reception angle and the beam transmission angle may be angles measured with reference to a LOS path formed between the communication device 100 and the electronic device 200.

[0343] In addition, the processor 290 may obtain whether at least one effective beam is formed within the sensing range of the sensor (not shown) (S121). The sensor (not shown) may obtain at least a part or all of the position and speed of the object.

[0344] In addition, when the processor 290 obtains that an effective beam is formed within the sensing range of the sensor (not shown), a reference range may be set (S122). The reference range may be a range in which an A / V signal transmission and reception failure is expected to occur during the object monitoring execution described later. The reference range may be a range that becomes a reference for the processor 290 to transmit a beam change instruction or a beam restoration instruction during the object monitoring execution described later.

[0345] In addition, the processor 290 may start object monitoring (S131). The object monitoring may be an action of monitoring at least a part or all of the position and speed of an object located between the communication device 100 and the electronic device 200.

[0346] On the other hand, the processor 290 may adjust the set reference range (S132). The processor 290 may adjust the reference range according to the object, or may not adjust the reference range. That is, according to an embodiment, step S132 may be an omissible step. The processor 290 may adjust the reference range set in step S122. For example, the processor 290 may obtain the speed of the object and adjust the reference range based on the speed of the object.

[0347] The electronic device 200 of the embodiment of the present specification can adjust the width of the reference range in real time according to the speed of the object, and can maximize the time of transmitting the A / V signal with the main beam with a fast transmission speed, while maximizing the transmission efficiency and minimizing the A / V signal transmission and reception errors. The processor 290 can obtain whether the object enters the reference range (S133).

[0348] When the processor 290 determines that the object has not entered the reference range, the processor 290 may not transmit the beam change instruction and continue to determine whether the object has entered the reference range.

[0349] On the other hand, when the processor 290 obtains that the object has entered the reference range, a beam change instruction may be transmitted to the communication device 100 (S141). The beam change instruction may be an instruction for changing the beam for transmitting and receiving A / V signals. According to the beam change instruction, any beam in the effective beam may be changed to a beam for transmitting and receiving A / V signals. According to the beam change instruction, the beam selected as the beam for transmitting and receiving A / V signals may be a sub-beam.

[0350] In connection with this, when an object enters the reference range, causing the wireless communication performance on the LOS path between the communication device 100 and the electronic device 200 to decrease, a wireless link can be set through other paths. The electronic device 200 can set a wireless link so that the wireless signal transmitted from the communication device 100 is reflected by the ceiling or wall. To this end, the electronic device 200 can form a beamforming wireless signal toward the ceiling direction (upper direction). The plurality of patch antennas PA11 to PA18 of the first row of the first array antenna 1200a in the front direction can be adjusted, and the phase of the signal applied to the plurality of patch antennas PA21 to PA28 in the second row can be adjusted so that the beamforming wireless signal is directed toward the upper front direction.

[0351] On the other hand, the processor 290 may obtain whether the object has left the reference range (S142). The processor 290 may obtain whether the object has left the reference range after the beam is changed because the object enters the reference range.

[0352] If the processor 290 determines that the object has not left the reference range, it may not send a beam restoration instruction and continue to determine whether the object has left the reference range. On the other hand, if the processor 290 determines that the object has left the reference range, it may send a beam restoration instruction to the communication device 100 (S143).

[0353] The electronic device with the antenna module is described above. The technical effects of the electronic device with the antenna module of this specification are as follows.

[0354] The electronic device of this embodiment can perform A / V wireless communication of data regardless of the location of the A / V transmitting device by using the first antenna structure and the second antenna structure configured with a plurality of array antennas.

[0355] In addition, the A / V transmission device can transmit data in a dual-stream manner, thereby minimizing the degradation of image quality caused by increasing the data compression rate.

[0356] In addition, a horizontally polarized antenna and a vertically polarized antenna can be disposed on one substrate at the same time, thereby having the advantages of being able to make the antenna module compact and improving the data reception rate.

[0357] In addition, according to the array antenna configuration structure of the A / V transmission device and the electronic device, it is possible to use horizontally polarized and vertically polarized signals to increase communication capacity while performing A / V wireless communication with reduced interference between them.

[0358] In addition, considering the positions of the A / V transmission device and the electronic device and the polarization characteristics of the array antenna, it is possible to utilize horizontally polarized and vertically polarized signals to perform A / V wireless communication that reduces interference between them while increasing communication capacity.

[0359] Furthermore, even when an obstacle is placed on the wireless communication path between the A / V transmission device and the electronic device, A / V wireless communication can be provided uninterruptedly by changing the beamforming direction and utilizing reflected waves.

However, since those skilled in the art can clearly understand various changes and modifications within the concept and scope of this specification, it should be understood that the detailed description and specific embodiments such as the preferred embodiments of this specification are provided only as examples.
