Description

[Technical field]

[0001] The present invention relates to electronic devices, and more particularly to electronic devices having antenna modules for wirelessly receiving data.

[0002] Related Art This application claims priority under Article 4 of the Paris Convention based on Korean Patent Application No. 10-2023-0077405 (filing date: June 16, 2023; DAS: AEC6), and the present application is based on the contents disclosed in the Korean patent application. For reference, the contents of the specification, claims and drawings of the Korean patent application are incorporated herein by reference. [Background technology]

[0003] As video technology has changed from analog to digital, it has evolved from SD (Standard-Definition) to HD (Hi-Definition) to provide images closer to the real thing. SD supports a resolution of 704 x 480 and is composed of about 350,000 pixels. HD is divided into HD and Full HD, of which Full HD, which supports a higher resolution, supports a resolution of 1920 x 1080 and is composed of 2 million pixels, providing images of much higher quality than SD.

[0004] Recent video technology has progressed beyond Full HD to UHD (Ultra High-Definition), which supports ultra-high picture quality and resolution and is in the spotlight as the next-generation media environment. UHD supports 4K (3840 x 2160) and 8K (7680 x 4320) resolutions and up to 22.2 channel surround audio. 4K UHD provides four times clearer picture quality than HD, and 8K UHD provides 16 times clearer picture quality than HD.

[0005] Recently, wireless display systems that transmit such high-resolution images wirelessly to a display device have appeared.

[0006] A wireless display system is a system in which A / V data is transmitted and received between an A / V transmitting device and an A / V receiving device via a short-range network.

[0007] The A / V receiving device displays the A / V data received from the A / V transmitting device.

[0008] For example, the A / V transmitting device may be a transmitting box having an antenna module that transmits A / V data wirelessly.

[0009] For example, the A / V receiving device may have an antenna module for receiving A / V data transmitted from an A / V transmitting device, and may be a display device for outputting the received A / V data.

[0010] The display device may include a pair of antenna modules and an IR module located between the pair of antenna modules, and the pair of antenna modules may be disposed spaced apart from each other on the left and right.

[0011] In the wireless display system, the antenna module of the A / V transmitting device may be located on the left or right side of the display device, in which case a pair of antenna modules provided in the display device may receive data transmitted from the antenna module of the A / V transmitting device in a two-stream manner, and the display device may output an image.

[0012] When the A / V transmitting device is located on the left or right side of the display device, one of the pair of antenna modules of the display device may not be able to receive data as the signal is blocked by the IR module, and the display device may operate in one stream.

[0013] When operating with one stream, the compression rate must be doubled compared to when operating with two streams in order to transmit and receive the same amount of data as when operating with two streams, but increasing the compression rate results in a decrease in the image quality level. Summary of the Invention [Problem to be solved by the invention]

[0145] Meanwhile, the first and second antenna structures arranged in the electronic device are formed in a multi-layer substrate structure. The first and second antenna structures are realized in a PCB (printed circuit board) structure. Note that Fig. 8A and Fig. 8B are cross-sectional views of the first and second antenna structures mounted on the first and second PCBs of the antenna arrangement structure of Fig. 5(a). Fig. 8C and Fig. 8D are cross-sectional views of the first and second antenna structures mounted on the first and second PCBs of the antenna arrangement structure of Fig. 5(b).

[0146] Fig. 8A(a) is a cross-sectional view of the first antenna structure 1000a arranged in the antenna arrangement structure of Fig. 5(a) and mounted on the first PCB 1010a.

[0148] Fig. 8C(a) is a cross-sectional view of the first antenna structure 1000a arranged in the antenna arrangement structure of Fig. 5(b) and mounted on the first PCB 1010a. Fig. 8C(b) is a diagram showing the three-dimensional structure of the first PCB 1010a formed by the first surface BS1 and the second surface BS2 to the fifth surface BS5.

[0149] Fig. 8D(a) is a cross-sectional view of the second antenna structure 1000b arranged in the antenna arrangement structure of Fig. 5(b) and mounted on the second PCB 1010b. Fig. 8D(b) is a diagram showing the three-dimensional structure of the second PCB 1010b formed by the first surface BS1 and the second surface BS2 to the fifth surface BS5.

[0150] The first and second antenna structures in Figures 8A to 8D correspond to the first antenna structure 1000a and the second antenna structure 1000b in Figure 7A. Therefore, in the first and second antenna structures in Figures 8A to 8D, the array antennas arranged on the front and side surfaces operate as horizontally polarized antennas, and the array antennas arranged on the bottom surface operate as horizontally or vertically polarized antennas.

[0151] As shown in Figures 4 to 7A, 8A and 8C, the first antenna structure 1000a forming a multi-layer structure includes a first PCB 1010a, a first array antenna 1200a, a second array antenna 1300a and a first wireless communication IC 1400a. The first antenna structure 1000a further includes a third array antenna 1100a and a fourth array antenna 1100b formed on the left and right sides. Since a plurality of ground layers 1110g and 1120g are arranged inside the first PCB 1010a, interference between signals of the plurality of array antennas is maintained below a certain level.

[0152] The first PCB 1010a has a plurality of side surfaces. The first PCB 1010a includes a first surface BS1 to a fifth surface BS5. Of the plurality of side surfaces, the first surface BS1 is formed to face the front D1 of the electronic device 200, and of the plurality of side surfaces, the second surface BS2 is formed to face the rear D2 of the electronic device 200. Of the plurality of side surfaces, the third surface BS3 is formed to face the left direction of the electronic device 200, and of the plurality of side surfaces, the fourth surface BS4 is formed to face the right direction of the electronic device 200. Of the plurality of side surfaces, the fifth surface BS5 is formed to face the downward direction D3 of the electronic device 200.

[0153] The first surface BS1 is formed to face a first direction (forward) D1. The second surface BS2 is formed to face a second direction (backward) D2 opposite to the first direction D1. The third surface BS3 to the fifth surface BS5 are formed to surround the space between the first surface BS1 and the second surface BS2.

[0154] A first array antenna 1200a is arranged on a first surface BS1 between a third surface BS3 and a fourth surface BS4. A second array antenna 1300a is arranged on a fifth surface BS5 between the third surface BS3 and the fourth surface BS4. The first array antenna 1200a forms a beam pattern in a first direction D1. The second array antenna 1300a forms a beam pattern in a fifth direction D5. A first wireless communication IC 1400a is arranged on the second surface BS2. The first wireless communication IC 1400a transmits and receives wireless signals in a first frequency range.

[0155] As shown in Figures 4 to 6, 7B, 8B and 8D, the second antenna structure 1000b forming a multi-layer structure includes a second PCB 1010b, a fifth array antenna 1200b, a sixth array antenna 1300b and a second wireless communication IC 1400b. The second antenna structure 1000b further includes a seventh array antenna 1100c and an eighth array antenna 1100d formed on the left and right sides. Since a plurality of ground layers 1110g and 1120g are arranged inside the second PCB 1010b, the interference between signals of the plurality of array antennas is maintained below a certain level.

[0156] The second PCB 1010b has a plurality of side surfaces. The second PCB 1010b includes a first surface BS1 to a fifth surface BS5. Of the plurality of side surfaces, the first surface BS1 is formed to face the front D1 of the electronic device 200, and of the plurality of side surfaces, the second surface BS2 is formed to face the rear D2 of the electronic device 200. Of the plurality of side surfaces, the third surface BS3 is formed to face the left direction of the electronic device 200, and of the plurality of side surfaces, the fourth surface BS4 is formed to face the right direction of the electronic device 200. Of the plurality of side surfaces, the fifth surface BS5 is formed to face the downward direction D3 of the electronic device 200.

[0157] The first surface BS1 is formed to face a first direction (forward) D1. The second surface BS2 is formed to face a second direction (backward) D2 opposite to the first direction D1. The third surface BS3 to the fifth surface BS5 are formed to surround the space between the first surface BS1 and the second surface BS2.

[0158] A fifth array antenna 1200b is arranged on a first surface BS1 between a third surface BS3 and a fourth surface BS4. A sixth array antenna 1300b is arranged on a fifth surface BS5 between a third surface BS3 and a fourth surface BS4. The fifth array antenna 1200b forms a beam pattern in a first direction D1. The sixth array antenna 1300b forms a beam pattern in a fifth direction D5. A second wireless communication IC 1400b is arranged on a second surface BS2. The second wireless communication IC 1400b transmits and receives wireless signals in a first frequency range.

[0159] The polarization of the first array antenna 1200a is formed in the same manner as the polarization of the fifth array antenna 1200b. The first array antenna 1200a forms a polarized wave in the Y-axis direction and radiates a polarized signal traveling in the X-axis direction. The fifth array antenna 1200b forms a polarized wave in the Y-axis direction and radiates a polarized signal traveling in the X-axis direction.

[0160] For a signal traveling forward in the X-axis direction, if the signal forms a polarized wave in the Y-axis direction, it corresponds to a horizontally polarized signal, and if the signal forms a polarized wave in the Z-axis direction, it corresponds to a vertically polarized signal. Therefore, the first array antenna 1200a and the fifth array antenna 1200b radiate horizontally polarized signals in the Y-axis direction. The horizontally polarized signal is a signal in which an electric field is formed in the Y-axis direction according to the length of the first antenna structure 1000a.

[0161] The polarization of the third array antenna 1100a is formed in the same manner as the polarization of the fourth array antenna 1100b. The third array antenna 1100a forms a polarized wave in the X-axis direction and radiates a polarized signal traveling leftward in the Y-axis direction. The fourth array antenna 1100b forms a polarized wave in the X-axis direction and radiates a polarized signal traveling rightward in the Y-axis direction.

[0162] For a signal traveling in the lateral Y-axis direction, if the signal forms a polarized wave in the X-axis direction, it corresponds to a horizontally polarized signal, and if the signal forms a polarized wave in the Z-axis direction, it corresponds to a vertically polarized signal. Therefore, the third array antenna 1100a and the fourth array antenna 1100b radiate horizontally polarized signals in the X-axis direction.

[0163] The polarization of the second array antenna 1300a is formed to be different from the polarization of the sixth array antenna 1300b. The polarization of the second array antenna 1300a is formed to be orthogonal to the polarization of the sixth array antenna 1300b. The second array antenna 1300a forms a polarization in the Y-axis direction and radiates a polarized signal traveling downward in the Z-axis direction. The sixth array antenna 1300b forms a polarization in the X-axis direction and radiates a polarized signal traveling downward in the Z-axis direction.

[0164] In a signal traveling in the Z-axis direction, if the signal forms a polarized wave in the Y-axis direction, it corresponds to a horizontally polarized signal, and if the signal forms a polarized wave in the X-axis direction, it corresponds to a vertically polarized signal. Therefore, the second array antenna 1300a radiates a horizontally polarized signal in the Y-axis direction. The sixth array antenna 1300b radiates a vertically polarized signal in the X-axis direction. As another example, the second array antenna 1300a may radiate a vertically polarized signal, and the sixth array antenna 1300b may radiate a horizontally polarized signal.

[0165] The polarization of the seventh array antenna 1100c is formed in the same manner as the polarization of the eighth array antenna 1100d. The third array antenna 1100c forms a polarized wave in the X-axis direction and radiates a polarized signal traveling leftward in the Y-axis direction. The eighth array antenna 1100d forms a polarized wave in the X-axis direction and radiates a polarized signal traveling rightward in the Y-axis direction. Therefore, the seventh array antenna 1100c and the eighth array antenna 1100d radiate horizontally polarized signals in the X-axis direction.

[0166] The communication device 100, which transmits and receives wireless signals to and from the electronic device 200, radiates horizontally polarized signals. When the communication device 100 is located in the front or side area of ​​the electronic device 200, both the first antenna structure 1000a and the second antenna structure 1000b are operational. 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 is operational.

[0167] When the communication device 100 is located in the front area of ​​the electronic device 200, both of the array antennas 1200a and 1200b located in the front parts of the first antenna structure 1000a and the second antenna structure 1000b, which are capable of operating with the same polarization, operate to communicate simultaneously. The same polarization is either horizontal polarization or vertical polarization with respect to the floor surface in the front communication area.

[0168] When the communication device 100 is located in the left side region of the electronic device 200, communication is performed simultaneously with antennas located on the left side portions of the first antenna structure 1000a and the second antenna structure 1000b that can operate with the same polarization. The same polarization is either horizontal polarization or vertical polarization with respect to the floor surface in the side communication region.

[0169] When the communication device 100 is located in the right side region of the electronic device 200, communication is performed simultaneously with antennas located on the right side portions of the first antenna structure 1000a and the second antenna structure 1000b that can operate with the same polarization. The same polarization is either horizontal polarization or vertical polarization with respect to the floor surface in the side communication region.

[0170] Therefore, when the communication device 100 is located in either the left side region or the right side region of the electronic device 200, the array antennas located on the corresponding side of the first antenna structure 1000a and the second antenna structure 1000b all operate. On the other hand, when the communication device 100 is located in the lower region of the electronic device 200, either the array antennas 1300a, 1300b located on the lower surfaces of the first antenna structure 1000a and the second antenna structure 1000b operate.

[0171] Also, when the communication device 100 is located in the lower region of the electronic device 200, the communication device 100 communicates with either the first antenna structure 1000a or the second antenna structure 1000b, which can operate with different polarizations. When the communication device 100 is in a position where it forms a horizontal polarization with the wall surface, it is the first antenna structure 1000a that forms the same 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 does not communicate with the second antenna structure 1000b of the electronic device 200.

[0172] When the communication device 100 is located in the lower region of the electronic device 200, it communicates with either the first antenna structure 1000a or the second antenna structure 1000b, which can operate with different polarizations. When the communication device 100 is in a position to form a polarization perpendicular to the wall surface, it is the second antenna structure 1000b that forms the same 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 does not communicate with the first antenna structure 1000a of the electronic device 200.

[0173] When the communication device 100 is located in the front area, the patch array antennas on the front sides of the first antenna structure 1000a and the second antenna structure 1000b each radiate polarized signals that can be communicated with the communication device 100. The polarized signals may be horizontally polarized or vertically polarized.

[0174] When the communication device 100 is located in a side area, one of the array antennas on the side of each of the first antenna structure 1000a and the second antenna structure 1000b radiates a polarized signal that can be communicated with the communication device 100. The polarized signal may be horizontally polarized or vertically polarized.

[0175] When the communication device 100 is located in the lower region, the first wireless communication IC 1400a controls the horizontally polarized signal to be transmitted and received via the second array antenna 1300a of the first antenna structure 1000a.

[0176] Since the communication device 100 is located in the lower region, the second wireless communication IC 1400b transmits and receives vertically polarized signals via the sixth array antenna 1300b of the second antenna structure 1000b.

Since a plurality of ground layers 1110g and 1120g are arranged inside the fourth PCB 1010d, the interference between signals of the plurality of array antennas is maintained below a certain level.

[0237] The fourth PCB 1010d has a plurality of side surfaces. The fourth PCB 1010d includes a first surface BS1 to a fifth surface BS5. Of the plurality of side surfaces, the first surface BS1 is formed to face the front D1 of the electronic device 200, and of the plurality of side surfaces, the second surface BS2 is formed to face the rear D2 of the electronic device 200. Of the plurality of side surfaces, the third surface BS3 is formed to face the left direction of the electronic device 200, and of the plurality of side surfaces, the fourth surface BS4 is formed to face the right direction of the electronic device 200. Of the plurality of side surfaces, the fifth surface BS5 is formed to face the downward direction D3 of the electronic device 200.

[0238] The first surface BS1 is formed to face a first direction (forward) D1. The second surface BS2 is formed to face a second direction (backward) D2 opposite to the first direction D1. The third surface BS3 to the fifth surface BS5 are formed to surround the space between the first surface BS1 and the second surface BS2.

[0239] A fifth array antenna 1200b is arranged on a first surface BS1 between a third surface BS3 and a fourth surface BS4. A sixth array antenna 1300d is arranged on a fifth surface BS5 between a third surface BS3 and a fourth surface BS4. The fifth array antenna 1200d forms a beam pattern in a first direction D1. The sixth array antenna 1300d forms a beam pattern in a fifth direction D5. A second wireless communication IC 1400d is arranged on a second surface BS2. The second wireless communication IC 1400d transmits and receives wireless signals in a first frequency range.

[0240] The polarization of the first array antenna 1200c is formed in the same manner as the polarization of the fifth array antenna 1200d. The first array antenna 1200c forms a polarized wave in the Z-axis direction and radiates a polarized signal traveling in the X-axis direction. The fifth array antenna 1200d forms a polarized wave in the Y-axis direction and radiates a polarized signal traveling in the X-axis direction.

[0241] In a signal traveling forward in the X-axis direction, if the signal forms a polarized wave in the Y-axis direction, it corresponds to a horizontally polarized signal, and if the signal forms a polarized wave in the Z-axis direction, it corresponds to a vertically polarized signal. Thus, the first array antenna 1200c radiates a vertically polarized signal in the Z-axis direction, and the fifth array antenna 1200d radiates a horizontally polarized signal in the Y-axis direction. The horizontally polarized signal is a signal in which an electric field is formed in the Y-axis direction according to the length of the third antenna structure 1000c, and the vertically polarized signal is a signal in which an electric field is formed in the Z-axis direction according to the width of the third antenna structure 1000c.

[0242] The polarization of the third array antenna 1100e is formed in the same manner as the polarization of the fourth array antenna 1100f. The third array antenna 1100e forms a polarized wave in the Z-axis direction and radiates a polarized signal traveling to the left in the Y-axis direction. The fourth array antenna 1100f forms a polarized wave in the Z-axis direction and radiates a polarized signal traveling to the right in the Y-axis direction.

[0243] For a signal traveling in the lateral Y-axis direction, if the signal forms a polarized wave in the Z-axis direction, it corresponds to a vertically polarized signal, and if the signal forms a polarized wave in the Z-axis direction, it corresponds to a vertically polarized signal. Therefore, the third array antenna 1100e and the fourth array antenna 1100f radiate vertically polarized signals in the Z-axis direction.

[0244] The polarization of the second array antenna 1300c is formed to be different from the polarization of the sixth array antenna 1300d. The polarization of the second array antenna 1300c is formed to be orthogonal to the polarization of the sixth array antenna 1300d. The second array antenna 1300c forms a polarization in the Y-axis direction and radiates a polarized signal traveling downward in the Z-axis direction. The sixth array antenna 1300d forms a polarization in the X-axis direction and radiates a polarized signal traveling downward in the Z-axis direction.

[0245] In a signal traveling in the Z-axis direction, if the signal forms a polarized wave in the Y-axis direction, it corresponds to a horizontally polarized signal, and if the signal forms a polarized wave in the X-axis direction, it corresponds to a vertically polarized signal. Therefore, the second array antenna 1300c radiates a horizontally polarized signal in the Y-axis direction. The sixth array antenna 1300d radiates a vertically polarized signal in the X-axis direction. As another example, the second array antenna 1300c may radiate a vertically polarized signal, and the sixth array antenna 1300d may radiate a horizontally polarized signal.

[0246] The polarization of the seventh array antenna 1100g is formed in the same manner as the polarization of the eighth array antenna 1100h. The seventh array antenna 1100g forms a polarized wave in the Z-axis direction and radiates a polarized signal traveling leftward in the Y-axis direction. The eighth array antenna 1100h forms a polarized wave in the Z-axis direction and radiates a polarized signal traveling rightward in the Y-axis direction. Therefore, the seventh array antenna 1100g and the eighth array antenna 1100h radiate vertically polarized signals in the Z-axis direction.

[0247] The communication device 100, which transmits and receives wireless signals to and from the electronic device 200, radiates horizontally polarized signals. When the communication device 100 is located in the front or side area of ​​the electronic device 200, both the third antenna structure 1000c and the fourth antenna structure 1000d are operational. 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 is operational.

[0248] When the communication device 100 is located in the front area of ​​the electronic device 200, both of the array antennas 1200c and 1200d located in the front parts of the third antenna structure 1000c and the fourth antenna structure 1000d, which are capable of operating with the same polarization, operate to communicate simultaneously. The same polarization is either horizontal polarization or vertical polarization with respect to the floor surface in the front communication area.

[0249] When the communication device 100 is located in the left side region of the electronic device 200, communication is performed simultaneously with antennas located on the left side portions of the third antenna structure 1000c and the fourth antenna structure 1000d that can operate with the same polarization. The same polarization is either horizontal or vertical polarization with respect to the floor surface in the side communication region.

[0250] When the communication device 100 is located in the right side region of the electronic device 200, communication is performed simultaneously with antennas located on the right side portions of the third antenna structure 1000c and the fourth antenna structure 1000d that can operate with the same polarization. The same polarization is either horizontal polarization or vertical polarization with respect to the floor surface in the side communication region.

[0251] Therefore, when the communication device 100 is located in either the left side region or the right side region of the electronic device 200, the array antennas located on the corresponding side of the third antenna structure 1000c and the fourth antenna structure 1000d all operate. On the other hand, when the communication device 100 is located in the lower region of the electronic device 200, either the array antennas 1300c and 1300d located on the lower surface of the third antenna structure 1000c and the fourth antenna structure 1000d operate.

[0252] Also, when the communication device 100 is located in the lower region of the electronic device 200, the communication device 100 communicates with either the third antenna structure 1000c or the fourth antenna structure 1000d, which can operate with different polarizations. When the communication device 100 is in a position where it forms a horizontal polarization with the wall surface, it is the third antenna structure 1000c that forms the same 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 does not communicate with the fourth antenna structure 1000d of the electronic device 200.

[0253] When the communication device 100 is located in the lower region of the electronic device 200, it communicates with either the third antenna structure 1000c or the fourth antenna structure 1000d, which can operate with different polarizations. When the communication device 100 is in a position to form a polarization perpendicular to the wall surface, it is the fourth antenna structure 1000d that forms the same 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 does not communicate with the third antenna structure 1000c of the electronic device 200.

[0254] When the communication device 100 is located in the front area, the patch array antennas on the front sides of the third antenna structure 1000c and the fourth antenna structure 1000d each radiate polarized signals that can be communicated with the communication device 100. The polarized signals may be horizontally polarized or vertically polarized.

[0255] When the communication device 100 is located in the side area, one of the array antennas on each side of the third antenna structure 1000c and the fourth antenna structure 1000d radiates a polarized signal that can be communicated with the communication device 100. The polarized signal may be horizontally polarized or vertically polarized.

[0256] When the communication device 100 is located in the lower region, the first wireless communication IC 1400c controls the horizontally polarized signal to be transmitted and received via the second array antenna 1300c of the third antenna structure 1000c.

[0257] Since the communication device 100 is located in the lower region, the second wireless communication IC 1400d transmits and receives vertically polarized signals via the sixth array antenna 1300d of the fourth antenna structure 1000d.

[0258] On the other hand, the first and second antenna structures arranged in the electronic device according to the present invention each have multiple array antennas arranged in different regions of the PCB. Note that Fig. 12A is a diagram showing a structure in which a third antenna structure having multiple antenna arrays and the antenna arrangement structure of Fig. 5(a) performs wireless communication with communication devices at various positions.

[0259] As shown in Figures 5(a), 7B and 12A, the third antenna structure 1000c includes a first array antenna 1200c, a second array antenna 1300c, a third array antenna 1100e, and a fourth array antenna 1100f.

[0262] The number of elements of the array antenna of the communication device 100a is equal to the sum of the number of elements of the first array antenna 1200c of the third antenna structure 1000c and the number of elements of the fifth array antenna 1200d of the fourth antenna structure 1000d. The number of elements of the array antenna of the communication device 100a is greater than the sum of the number of elements of the second array antenna 1300c of the third antenna structure 1000c and the number of elements of the sixth array antenna 1300d of the fourth antenna structure 1000d.

[0265] The third array antenna 1100e is realized as a 1×3 array antenna in one side area of ​​the third PCB 1010c, but is not limited thereto. The fourth array antenna 1100f is realized as a 1×3 array antenna in the other side area of ​​the first PCB 1010a, but is not limited thereto.

[0266] The third array antenna 1100e and the fourth array antenna 1100f transmit and receive horizontally polarized signals to one side region and the other side region. The third array antenna 1100e transmits horizontally polarized signals to the communication device 100a arranged in the one side region and receives horizontally polarized signals therefrom. The communication device 100a and the third array antenna 1100a transmit and receive radio signals having the same polarization (co-polarization).

[0267] The first array antenna 1200c includes a plurality of patch antennas PA11-PA18, PA21-PA28 arranged in the front area of ​​the third PCB 1010c. Coupling patches CP11-CP18, CP21-CP28 are arranged at positions offset upward and downward in the Z-axis direction, which is the vertical direction, from the centers of the patch antennas PA11-PA18, PA21-PA28. Dummy pads DP11, DP21 are arranged on one side of the patch antennas PA11, P21, so that side surface radiation is suppressed. Dummy patch antennas DP12, DP22 are arranged on the other side of the patch antennas PA11, P21, so that side surface radiation is suppressed. The first array antenna 1200c is realized by 16 2×8 array antennas, but is not limited to this.

The communication device 100a and the second array antenna 1300c transmit and receive radio signals having the same polarization (co-polarization).

[0271] The communication device 100b is arranged in a state rotated at an arbitrary angle. The communication device 100b1 in the first rotation state and the second array antenna 1300c transmit and receive horizontally polarized signals having the same polarization (co-polarization). On the other hand, the communication device 100b2 in the second rotation state is located in a state in which it does not transmit or receive polarized signals of the electronic device 200. The second rotation state is a state rotated within a predetermined angle range based on 90 degrees from the first rotation state. 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-polarization that is orthogonal to each other. Therefore, the wireless communication performance may be degraded between the communication device 100b in the second rotation state and the third antenna structure 1000c, and communication may not be possible.

[0272] Therefore, the sixth array antenna 1300d, which is the underside antenna of the fourth antenna structure 1000d, is configured to transmit and receive vertically polarized signals to and from the communication device 100b in the second rotation state.

[0284] The second array antenna 1300c of the third antenna structure 1000c and the sixth array antenna 1300d of the second antenna structure 1000d are realized as array antennas of different structures. The second array antenna 1300a of the first antenna structure 1000a is a dipole antenna with a 1×10 arrangement, and the sixth array antenna 1300a is a monopole antenna with a 1×10 arrangement.

Coupling patches CP1 to CP12 are disposed at positions offset upward and downward in the Z-axis direction, which is the vertical direction, from the centers of the patch antennas PA1 to PA12. The sixth array antenna 1300d is realized by twelve 1×12 array antennas, but is not limited to this.

[0304] The sixth array antenna 1300d transmits and receives vertically polarized signals to the lower region. The sixth array antenna 1300d transmits vertically polarized signals to the communication device 100b arranged in the lower region, and receives vertically polarized signals therefrom. The communication device 100b and the sixth array antenna 1300d transmit and receive radio signals having the same polarization (co-polarization).

[0305] The seventh array antenna 1100g includes a plurality of dipole antennas DA21-DA23 arranged in one side area of ​​the fourth PCB 1010d. The eighth array antenna 1100h includes a plurality of dipole antennas DA24-DA26 formed in the other side area of ​​the fourth PCB 1010d. The seventh array antenna 1100g is realized as a 1×3 array antenna in one side area of ​​the fourth PCB 1010d, but is not limited thereto. The eighth array antenna 1100d is realized as a 1×3 array antenna in the other side area of ​​the fourth PCB 1010d, but is not limited thereto.

[0306] The seventh array antenna 1100g and the eighth array antenna 1100h transmit and receive vertically polarized signals to one side region and the other side region. The seventh array antenna 1100g transmits vertically polarized signals to the communication device 100c arranged in the one side region and receives vertically polarized signals therefrom. The communication device 100c and the seventh array antenna 1100g transmit and receive radio signals having the same polarization (co-polarization).

[0307] Having described above the electronic device having the first and second antenna structures with multiple array antennas, a method for wireless communication between the electronic device and a communication device will now be described in detail with reference to the accompanying drawings.

[0308] 14 is a flowchart showing the operation of the electronic device for transmitting and receiving A / V signals to and from the communication device according to the present invention. A method for transmitting and receiving wireless signals through a plurality of array antennas of the first and second antenna structures by the electronic device 200 according to the present invention will be described with reference to FIGS. 5 to 14.

[0309] When the communication device 100 and the electronic device 200 included in the wireless display system are powered on (S11), the electronic device 200 identifies the device ID of the communication device 100 (S12). The electronic device 200 searches for the position and rotation state in which the communication device 100 is placed (S13).

[0310] Based on the device ID, it is determined whether the communication device 100 provides dual polarized waves (S14). It is determined whether the antenna element of the communication device 100 can transmit and receive horizontally polarized signals and vertically polarized signals.

[0311] It is searched whether the communication device 100 is disposed in the front region, the bottom region, one side region, or the other side region of the electronic device 200. Therefore, the electronic device 200 determines whether the communication device 100 is disposed in the bottom region of the electronic device 200 (S15). If the communication device 100 supplies dual polarized waves, it determines whether the communication device 100 is disposed in the front region or the bottom region of the electronic device 200 (S16).

[0312] When the communication device 100 supplies a single polarized wave and is disposed in a lower region of the electronic device 200, the communication device 100 performs 1T1R operation using either the first antenna structure 1010a or the second antenna structure 1010b (S21). Thus, horizontally polarized signals are transmitted and received via the second array antenna 1300a of the first antenna structure 1010a. Alternatively, vertically polarized signals are transmitted and received via the sixth array antenna 1300d of the second antenna structure 1010b. Thus, the communication device 100 and the electronic device 200 perform 1T1R operation using either the first antenna structure 1010a or the second antenna structure 1010b.

[0313] When the communication device 100 supplies a single polarized wave and is disposed in the front area, one side area or the other side area of ​​the electronic device 200, a diversity operation is performed by the first antenna structure 1000a and the second antenna structure 1000b (S22). Thus, the first antenna structure 1000a and the second antenna structure 1000b perform a diversity operation of transmitting and receiving the same polarized signal.

[0314] When the communication device 100 provides dual polarized waves and is disposed in the front or bottom area of ​​the electronic device 200, both the first antenna structure 1000a and the second antenna structure 1000b are controlled to operate (S22).

[0315] When the seventh array antenna 1100c and the eighth array antenna 1100d supply vertically polarized waves, the first antenna structure 1010a and the second antenna structure 1010b perform 2T2R operation (S23). Thus, the 2T2R operation is performed by a multiple input multiple output (MIMO) operation that simultaneously transmits and receives vertically polarized signals and horizontally polarized signals.

[0316] When the seventh array antenna 1100c and the eighth array antenna 1100d do not supply vertically polarized waves, the first antenna structure 1010a and the second antenna structure 1010b perform 1T2R operation (S24). Therefore, the communication device 100 and the electronic device 200 perform 1T2R operation using either the first antenna structure 1010a or the second antenna structure 1010b.

[0317] Meanwhile, the electronic device according to the present invention appropriately selects a plurality of array antennas of the first and second antenna structures based on the location of the communication device and receives the A / V signal by optimal beamforming. Note that FIG. 15 is a flowchart showing a method for selecting, modifying or restoring a wireless beamforming signal for transmitting and receiving an A / V signal by the electronic device according to the present invention.

[0318] As shown in Fig. 14, the operation mode of a plurality of array antennas is selected / changed, and then a beam selection, change or restoration process is performed as shown in Fig. 15, but is not limited thereto. As shown in Fig. 15, if the area in which the communication device is located is changed while wireless communication is being performed in the beam selection, change or restoration process, the operation mode of the array antenna is changed as shown in Fig. 14.

[0319] A method for selecting, changing or restoring a wireless beamforming signal for transmitting and receiving an A / V signal by an electronic device will be described with reference to Fig. 1, Fig. 2, and Fig. 5 to Fig. 15. The processor 290 searches for beams that can be formed between the communication device 100 and the electronic device 200 (S111). The processor 290 obtains all beams that can be formed between the communication device 100 and the electronic device 200 as a search result. Meanwhile, all beams have a pair of beams consisting of a transmission beam that transmits an A / V signal from the communication device 100 and a reception beam that receives an A / V signal from the electronic device 200.

[0320] The processor 290 also obtains an effective beam from the beams 300 that are searched for as being formable between the communication device 100 and the electronic device 200 (S112). The effective beam may be one or more beams selected for actually transmitting and receiving A / V signals among all beams searched by the processor 290. Alternatively, the effective beam may be one or more beams that transmit and receive A / V signals at or above the minimum transmission rate among the beams 300 that can be formed between the communication device 100 and the electronic device 200.

[0321] The processor 290 also obtains a beam angle based on the beam ID (S113). The beam ID is an ID for identifying each beam 300 formed in the communication device 100 and the electronic device 200. The beam angle includes a beam reception angle, which is an angle on the electronic device 200 side, and a beam transmission angle, which is an angle on the communication device 100 side. The beam reception angle and the beam transmission angle are angles measured in an LOS path formed between the communication device 100 and the electronic device 200.

[0322] The processor 290 also determines whether at least one effective beam is formed within a detection range of a sensor (not shown) (S121). The sensor (not shown) obtains at least a part or all of the position and velocity of an object.

[0323] Furthermore, when the processor 290 determines that an effective beam is formed within the detection range of a sensor (not shown), it sets a reference range (S122). The reference range may be a range in which an A / V signal transmission / reception failure is expected to occur during object monitoring, which will be described later. The reference range may be a range that serves as a reference for the processor 290 to transmit a beam change command or a beam restoration command during object monitoring, which will be described later.

[0324] The processor 290 also starts object monitoring (S131). Object monitoring is an operation for monitoring at least a part or all of the position and velocity of an object located between the communication device 100 and the electronic device 200.

[0325] Meanwhile, the processor 290 adjusts the set reference range (S132). The processor 290 may adjust the reference range depending on the object, or may not adjust the reference range. That is, step S132 may be omitted depending on the embodiment. The processor 290 adjusts the reference range set in step S122. For example, the processor 290 obtains the velocity of the object and adjusts the reference range based on the velocity of the object.

[0326] Since the electronic device 200 according to an embodiment of the present invention can adjust the width of the reference range in real time in consideration of the speed of the object, the transmission efficiency can be maximized by maximizing the time during which the A / V signal is transmitted by the main beam having a high transmission speed, and the A / V signal transmission / reception error can be minimized. The processor 290 determines whether the object has entered the reference range (S133).

[0327] If the processor 290 determines that the object has not entered the reference range, it does not send a beam change command and continues to determine whether or not the object has entered the reference range.

[0328] On the other hand, when the processor 290 determines that the object has entered the reference range, it transmits a beam change command to the communication device 100 (S141). The beam change command is a command to change a beam for transmitting and receiving an A / V signal. The beam change command changes one of the valid beams to a beam for transmitting and receiving an A / V signal. The beam selected as the beam for transmitting and receiving an A / V signal by the beam change command is a sub-beam.

[0329] When an object enters the reference range and the wireless communication performance of the LOS path between the communication device 100 and the electronic device 200 deteriorates, a wireless link is established via another path. The electronic device 200 establishes a wireless link so that the wireless signal transmitted from the communication device 100 is reflected by the ceiling or wall surface. For this purpose, the electronic device 200 forms a beamforming wireless signal in the ceiling direction (upward). The phase of the signal applied to the patch antennas PA21-PA28 in the second row is adjusted relative to the patch antennas PA11-PA18 in the first row of the front first array antenna 1200a, so that the beamforming wireless signal faces upward in the front direction.

[0330] Meanwhile, processor 290 determines whether or not the object has deviated from the reference range (S142). When the object enters the reference range and the beam is changed, processor 290 determines whether or not the object has deviated from the reference range.

[0331] When the processor 290 determines that the object has not deviated from the reference range, it does not transmit a beam restoration command and continues to determine whether the object has deviated from the reference range. On the other hand, when the processor 290 determines that the object has deviated from the reference range, it transmits a beam restoration command to the communication device 100 (S143).

[0332] The above describes an electronic device equipped with an antenna module. The technical effects of the electronic device equipped with the antenna module according to the present invention are as follows.

[0333] The electronic device according to the present embodiment can perform A / V wireless data communication through the first and second antenna structures in which a plurality of array antennas are arranged, regardless of the location of an A / V transmitting device.

[0334] In addition, the A / V transmitting device can transmit two streams of data, minimizing the degradation of image quality that occurs when the data compression rate is increased.

[0335] Furthermore, since a horizontally polarized antenna and a vertically polarized antenna are both arranged on a single board, the antenna module can be made compact, which has the advantage of increasing the data reception rate.

[0336] Furthermore, depending on the array antenna arrangement structure of the A / V transmitting device and the electronic device, horizontally polarized and vertically polarized signals can be used to perform A / V wireless communication with increased communication capacity and reduced mutual interference.

[0337] Furthermore, by taking into account the positions of the A / V transmitting device and electronic device and the polarization characteristics of the array antenna, horizontally polarized and vertically polarized signals can be used to perform A / V wireless communication with increased communication capacity and reduced mutual interference.

[0338] Furthermore, an object of the present invention is to provide A / V wireless communication that will not be interrupted even if an obstacle is present on the wireless communication path between an A / V transmitting device and an electronic device by changing the beamforming direction and using reflected waves.

[0339] Further scope of applicability of the present invention will become apparent from the above detailed description. However, since various changes and modifications within the spirit and scope of the present invention will be clearly understood by those skilled in the art, the detailed description and specific embodiments such as the preferred embodiment are merely illustrative of the present invention.
