[0021] An electronic device such as a portable device or a multi-function device may include a radar (radio detection and ranging) system to obtain information about external devices around the electronic device. The radar system may include an antenna for transmitting and receiving radio waves, an integrated circuit (IC) (e.g., a front-end IC) including a transmission path (Tx path) for transmitting radio waves and a reception path (Rx path) for receiving radio waves. Since the radar system includes the antenna and the IC, the installation space of the radar system relative to the electronic device may be relatively large. Therefore, a method for reducing the size of the radar system may be required in the electronic device.

[0022] Figure 1 An example of a functional configuration of an electronic device according to an embodiment is shown.

[0023] refer to Figure 1 , the electronic device 101 may include components including a processor 120, a memory 130, a display 140, and a radar system 145 (e.g., an integrated circuit (IC) 150 and an antenna array 160). These components are merely exemplary. For example, the electronic device 101 may also include another component (e.g., a power management integrated circuit (PMIC)). For example, some components may be omitted from the electronic device 101.

[0024] The processor 120 can be implemented with one or more integrated circuit (IC) chips, and can perform various data processing. For example, the processor 120 can be implemented as a system on chip (SoC). The processor 120 includes subcomponents, including a central processing unit (CPU), a graphics processing unit (GPU), a neural processing unit (NPU), an image signal processor (ISP), a display controller, a memory controller, a storage controller, a communication processor (CP) and / or a sensor interface. The subcomponents are merely exemplary. For example, the processor 120 may also include other subcomponents. For example, the processor 120 may also include other subcomponents. For example, some subcomponents may be omitted from the processor 120. In an embodiment, the processor 120 may be configured to use the radar system 145 in the electronic device 101 to obtain information about external objects around the electronic device 101 (e.g., the relative positional relationship between external objects, the movement of external objects, and / or the posture of external objects). For example, the processor 120 may be configured to control the radar system 145 to send radio waves toward the external object. For example, the radio waves may be reflected from the external object and returned to the radar system 145. For example, the processor 120 may be configured to control the radar system 145 to receive radio waves returned to the radar system 145. For example, the processor 120 may be configured to obtain information about an external object based on the received radio waves.

[0025] The memory 130 may be used to store one or more programs including instructions. For example, the instructions may be executed by the processor 120. For example, the memory 130 may include volatile memory and / or non-volatile memory. As used herein, "based on" encompasses at least based on.

[0026] The display 140 may be used to display images obtained by the processor 120 .

[0027] The radar system 145 may include an IC 150 and an antenna array 160. The IC 150 for the radar system 145 may include a circuit for transmitting and receiving radio waves. For example, the IC 150 may include a transmission front-end circuit and a reception front-end circuit. For example, the IC 150 may include a plurality of paths and at least one switch, wherein the plurality of paths include at least one transmission path (Tx path) and at least one reception path (Rx path). In an embodiment, the IC 150 may also include a digital-to-analog converter (DAC) and an analog-to-digital converter (ADC). In an embodiment, the IC 150 may also include a voltage-controlled oscillator (VCO). In an embodiment, the IC 150 may also include a baseband amplifier. In an embodiment, the IC 150 may also include at least one filter. However, it is not limited thereto.

[0028] In an embodiment, IC 150 may be dedicated only to radar system 145. In an embodiment, IC 150 may be at least one IC for communicating with an external electronic device and for supporting an antenna array including a plurality of antenna elements. For example, at least one IC may include an RFIC and / or an intermediate frequency (IF) IC. However, it is not limited thereto. For example, when IC 150 is at least one IC, IC 150 may be used for radar system 145 in other time resources different from time resources for communicating with an external electronic device. However, it is not limited thereto.

[0029] The antenna array 160 for the radar system 145 may include a plurality of antennas. For example, the plurality of antennas may be arranged in an arrangement for forming a virtual antenna array. For example, the distance between an antenna in the plurality of antennas and another antenna in the plurality of antennas immediately adjacent to the antenna may be greater than half the wavelength (e.g., the minimum wavelength) of a signal transmitted from the radar system 145.

[0030] In an embodiment, the antenna array 160 may be dedicated only to the radar system 145. In an embodiment, the antenna array 160 may be an antenna array including a plurality of antenna elements for communicating with an external electronic device. For example, when the antenna array 160 is an antenna array including a plurality of antenna elements, the antenna array 160 may be used for the radar system 145 in other time resources different from the time resources for communicating with the external electronic device. However, it is not limited thereto.

[0031] In an embodiment, the plurality of antennas in antenna array 160 may include an antenna connected to a Tx path in IC 150 and an antenna connected to an Rx path in IC 150. In an embodiment, the plurality of antennas may include an antenna electrically connected to a Tx path or an Rx path in the plurality of paths in IC 150 through a switch in IC 150. For example, Figure 2 A description is provided to illustrate multiple antennas. Figure 2 An example of a configuration of a radar system in an electronic device according to an embodiment is shown.

[0032] For example, refer to Figure 2, the plurality of antennas in the antenna array 160 may include a first antenna 221 electrically connected directly or indirectly to the first Tx path 201 in the IC 150, a third antenna 223 electrically connected directly or indirectly to the first Rx path 211 in the IC 150, and a second antenna 222 electrically connected directly or indirectly to the second Tx path 202 or the second Rx path 212 through the switch 230 in the IC 150. In an embodiment, the first Tx path 201 may include a first power amplifier (PA) 241 for setting the transmission power of the first signal sent through the first antenna 221. For example, the first signal may be a signal having a frequency that changes according to time. For example, the first signal may be a linear frequency modulation (chirp) signal. However, it is not limited thereto. In an embodiment, the second Tx path 202 may include a second PA 242 for setting the Tx power of the second signal sent through the second antenna 222. For example, the second signal may be a signal having a frequency that changes according to time. For example, the second signal may be a linear frequency modulation signal. However, it is not limited thereto. In an embodiment, the first Rx path 211 may include a first low noise amplifier (LNA) 251 for amplifying power of a signal (eg, a first reflected signal regarding the first signal and a second reflected signal regarding the second signal) received through the third antenna 223. Figure 2 , the first Rx path 211 may further include a first mixer and a first filter. However, it is not limited thereto. In an embodiment, the second Rx path 212 may include a second LNA 252 for amplifying the power of a signal (eg, a first reflected signal) received through the second antenna 222. Although not shown in FIG. Figure 2 , but the second Rx path 212 may also include a second mixer and a second filter. However, it is not limited thereto.

[0033] In an embodiment, the processor 120 may transmit a first signal in a first time interval (e.g., a first frame) through a first antenna 221 electrically connected to the first Tx path 201. The processor 120 may receive a first reflected signal in the first time interval in which the first signal is reflected from an external object around the electronic device 101 through a third antenna 223 electrically connected to the first Rx path 211 and a second antenna 222 electrically connected to the second Rx path 212 through a switch 230. For example, the first reflected signal may be used to obtain at least one of first data about a relative position relationship (e.g., a distance between the electronic device 101 and the external object), second data about movement of the external object, or third data about a posture of the external object.

[0034] At the same time, the processor 120 can receive the first reflected signal about the first signal transmitted through the first antenna 221 through the second antenna 222 and the third antenna 223 to use two virtual antennas in the virtual antenna array. For example, the two virtual antennas in the virtual antenna array can be defined based on the transmission through the first antenna 221, the reception through the second antenna 222, and the reception through the third antenna 223.

[0035] In an embodiment, the processor 120 may transmit a second signal through a second antenna 222 in a second time interval (e.g., a second frame), and the second antenna 222 is electrically connected to the second Tx path 202 through the switch 230. For example, the second time interval may be a time interval after the first time interval. The processor 120 may receive a second reflected signal reflected from an external object around the electronic device 101 through a third antenna 223 electrically connected to the first Rx path 211 in the second time interval. For example, the second reflected signal may be used together with the first reflected signal to obtain at least one of the first data, the second data, or the third data.

[0036] At the same time, the processor 120 can receive a second reflected signal about the second signal transmitted through the second antenna 222 through the third antenna 223 to use a virtual antenna different from the two virtual antennas in the virtual antenna array. For example, the virtual antenna in the virtual antenna array can be defined based on the transmission through the second antenna 222 and the reception through the third antenna 223.

[0037] For example, the first antenna 221, the second antenna 222, and the third antenna 223 may be arranged to form a virtual antenna array. For example, the arrangement of the virtual antennas in the virtual antenna array may be defined based on the arrangement of the first antenna 221, the second antenna 222, and the third antenna 223. For example, the arrangement of the virtual antennas in the virtual antenna array defined based on the arrangement of the first antenna 221, the second antenna 222, and the third antenna 223 may be defined by Figure 3 and Figure 4 . Figure 3 and Figure 4 An example of forming a virtual antenna array using a radar system in an electronic device according to an embodiment is shown.

[0038] For example, refer to Figure 3, the first antenna 221, the second antenna 222, and the third antenna 223 may form a virtual antenna array 300, the second antenna 222 is disposed at a position spaced apart from the first antenna 221 by a distance "a" in the x-axis direction and by a distance "b" in the -y-axis direction, and the third antenna 223 is disposed at a position spaced apart from the first antenna 221 in the x-axis direction. For example, the first virtual antenna 310 may be formed in the virtual antenna array 300 based on transmitting a first signal through the first antenna 221 in a first time interval and receiving a first reflected signal about the first signal through the second antenna 222 in the first time interval. For example, the first virtual antenna 310 in the virtual antenna array 300 may be defined based on a relative positional relationship between the first antenna 221 and the second antenna 222. For example, the second virtual antenna 320 may be formed in the virtual antenna array 300 based on transmitting a first signal through the first antenna 221 in a first time interval and receiving a first reflected signal about the first signal through the third antenna 223 in the first time interval. For example, the second virtual antenna 320 in the virtual antenna array 300 may be defined based on the relative positional relationship between the first antenna 221 and the third antenna 223. For example, the third virtual antenna 330 may be formed in the virtual antenna array 300 based on the second signal transmitted through the second antenna 222 in the second time interval and the second reflected signal received through the third antenna 223 in the second time interval regarding the second signal. For example, the third virtual antenna 330 in the virtual antenna array 300 may be defined in the virtual antenna array 300 based on the relative positional relationship between the first antenna 221 and the second antenna 222 and the position of the second virtual antenna 320. For example, when the second antenna 222 is spaced apart from the first antenna 221 by a distance 'a' in the x-axis direction and by a distance 'b' in the -y-axis direction, the virtual antenna 330 may be defined in the virtual antenna array 300 at a position spaced apart from the second virtual antenna 320 by a distance 'a' in the x-axis direction and by a distance 'b' in the -y-axis direction, and the second virtual antenna 320 is formed based on the relative positional relationship between the first antenna 221 and the third antenna 223. However, it is not limited thereto.

[0039] For another example, see Figure 4, when the first antenna 221, the second antenna 222, and the third antenna 223 are arranged in the x-axis direction, the virtual antenna array 400 formed based on the first antenna 221, the second antenna 222, and the third antenna 223 may be different from the virtual antenna array 300. For example, the first virtual antenna 410 may be formed in the virtual antenna array 400 based on the first signal being transmitted through the first antenna 221 in the first time interval and the first reflected signal being received through the second antenna 222 in the first time interval with respect to the first signal. For example, the first virtual antenna 410 in the virtual antenna array 400 may be defined based on the relative positional relationship between the first antenna 221 and the second antenna 222. For example, the second virtual antenna 420 may be formed in the virtual antenna array 400 based on the first signal being transmitted through the first antenna 221 in the first time interval and the first reflected signal being received through the third antenna 223 in the first time interval with respect to the first signal. For example, the second virtual antenna 420 in the virtual antenna array 400 may be defined based on the relative positional relationship between the first antenna 221 and the third antenna 223. For example, the third virtual antenna 430 may be formed in the virtual antenna array 400 based on transmitting the second signal through the second antenna 222 in the second time interval and receiving the second reflected signal about the second signal through the third antenna 223 in the second time interval. For example, the third virtual antenna 430 in the virtual antenna array 400 may be defined within the virtual antenna array 400 based on the relative positional relationship between the first antenna 221 and the second antenna 222 and the position of the second virtual antenna 420. For example, when the second antenna 222 is spaced apart from the first antenna 221 by a distance 'c' in the x-axis direction, the virtual antenna 430 may be defined within the virtual antenna array 400 at a position spaced apart from the second virtual antenna 420 by a distance 'c' in the x-axis direction, the second virtual antenna 420 being formed based on the relative positional relationship between the first antenna 221 and the third antenna 223. However, it is not limited thereto.

For example, the first antenna 221, the second antenna 222, the third antenna 223, the fourth antenna 224, and the fifth antenna 225 may be disposed along the periphery of the display of the TV 667. However, it is not limited thereto.

[0044] refer to Figure 2In order to obtain information about an external object, the distance between the first antenna 221 for transmitting the first signal and the second antenna 222 for transmitting the second signal may need to be equal to or greater than a specific distance. For example, in order to ensure the difference between the path of the first reflected signal and the path of the second reflected signal, the distance between the first antenna 221 and the second antenna 222 may need to be equal to or greater than a specific distance. Since the electronic device 101 includes the second antenna 222 electrically connected to the second Tx path 202 or the second Rx path 212 through the switch 230, the first antenna 221 and the second antenna 222 spaced a certain distance or more from the first antenna 221 can be set in a minimized (or optimized) space. For example, by Figure 7 The arrangements of the antennas shown in are compared to illustrate the arrangements of the first antenna 221 and the second antenna 222 in a minimized (or optimized) or reduced space. Figure 7 An exemplary arrangement of an antenna in a radar system is shown, which is disposed on or within a display of an electronic device.

[0045] For example, refer to Figure 7 , the electronic device 700 may include a first antenna 701 connected to a Tx path, a second antenna 702 connected to another Tx path, and third antennas 703 to 706 connected to Rx paths, respectively. Figure 2 Unlike the electronic device 101 in the embodiment, the electronic device 700 may include a second antenna 702 connected to another Tx path. Figure 2The electronic device 101 in the embodiment includes a second antenna 222 electrically connectable to the second Tx path 202 or the second Rx path 212 through the switch 230. The distance "Dtx" between the first antenna 701 and the second antenna 702 in the electronic device 700 may be equal to or greater than a specific distance to ensure a difference between a path of a reflected signal regarding a signal transmitted through the first antenna 701 and a path of a reflected signal regarding a signal transmitted through the second antenna 702. The electronic device 700 may include the third antenna 703 to the sixth antenna 706 spaced apart from the periphery 711 of the display 710 by a distance "Xrx", the first antenna 701 spaced apart from the periphery 711 of the display 710 by a distance "Xtx" longer than the distance "Xrx", and the second antenna 702 spaced apart from the periphery 711 of the display 710 by a distance "Xtx" and spaced apart from the first antenna 701 by a distance "Dtx", so that the distance "Dtx" between the first antenna 701 and the second antenna 702 is equal to or greater than a specific distance. For example, the first to sixth antennas 701 to 706 may be directly or indirectly disposed on a metal plate 720 having a grid pattern, the metal plate 720 being disposed between a plurality of pixels of the display 710 and the glass on the display 710. For example, since the metal plate 720 includes the third to sixth antennas 703 to 706 spaced apart from the periphery 711 of the display 710 by a distance “Xrx”, the first antenna 701 spaced apart from the periphery 711 of the display 710 by a distance “Xtx”, and the second antenna 702 spaced apart from the periphery 711 of the display 710 by a distance “Xtx” and spaced apart from the first antenna 701 by a distance “Dtx”, the metal plate 720 may have an area larger than a value obtained by multiplying the distance “Dtx” between the first antenna 701 and the second antenna 702 by the distance “Xtx” by which the first antenna 701 and the second antenna 702 are respectively spaced apart from the periphery 711 of the display 710.

[0046] At the same time, reference Figure 2 and Figure 6 Since the electronic device 101 includes the second antenna 222 electrically connected to the second Tx path 202 or the second Rx path 212 through the switch 230, Figure 7Unlike the electronic device 700 shown, the first antenna 221, the second antenna 222, the third antenna 223, the fourth antenna 224, and the fifth antenna 225 may be arranged in a row. For example, since the second antenna 222 may be electrically connected to the second Tx path 202 or the second Rx path 212 through the switch 230, the second antenna 222, which is spaced a certain distance or more from the first antenna 221 and a certain distance or more from each of the third antenna 223 to the fifth antenna 225, may be arranged in a row together with the first antenna 221, the third antenna 223, the fourth antenna 224, and the fifth antenna 225 so as to ensure a difference between a path of a reflected signal of a signal transmitted through the first antenna 221 and a path of a reflected signal of a signal transmitted through the second antenna 222. For example, the electronic device 101 may include the third antenna 223, the fourth antenna 224, and the fifth antenna 225 arranged between the first antenna 221 and the second antenna 222. For example, Figure 7 Unlike the electronic device 700 shown in FIG. 1 , the electronic device 101 may include the first antenna 221 to the fifth antenna 225, which are spaced apart from the first periphery 501 of the display 140 by a distance “Xrx”. For example, since the first antenna 221 to the fifth antenna 225 are arranged in a row, the metal plate 600 including the first antenna 221 to the fifth antenna 225 may be thinner than the metal plate 600. Figure 7 The area of ​​the metal plate 720 shown is narrow. For example, the metal plate 600 may have an area larger than a value obtained by multiplying the distance "Dtx" between the first antenna 221 and the second antenna 222 by the distance "Xrx" separating each of the first antenna 221 to the fifth antenna 225 from the first periphery 501 of the display 140, but may have an area narrower than the metal plate 720.

[0047] For example, since the pixels within each of the display 140 and the display 710 are covered by the metal plate 600 and the metal plate 720, the pixels within each of the display 140 and the display 710 may need to emit light with a higher intensity than other pixels within each of the display 140 and the display 710. For example, since the metal plate 600 has a narrower area than the metal plate 720, the electronic device 101 can display a screen through the display 140 based on less power than the power consumed by the electronic device 700 to display a screen through the display 710.

[0048] For another example, since the first antenna 221 and the second antenna 222 in the electronic device 101 are spaced apart from the first periphery 501 of the display 140 by a distance "Xrx" that is shorter than the distance "Xtx" that each of the first antenna 701 and the second antenna 702 in the electronic device 700 is spaced apart from the periphery 711 of the display 710, each of the first feed line 621 and the second feed line 622 of the first antenna 221 and the second antenna 222 may be shorter than each of the first feed line 751 and the second feed line 752 of the first antenna 701 and the second antenna 702. For example, each of the first feed line 621 and the second feed line 622 of the first antenna 221 and the second antenna 222 is shorter than each of the first feed line 751 and the second feed line 752 of the first antenna 701 and the second antenna 702, and a loss caused by each of the first feed line 621 and the second feed line 622 may be smaller than a loss caused by each of the first feed line 751 and the second feed line 752. For example, degradation in gain of each of the first antenna 221 and the second antenna 222 within the electronic device 101 may be less than degradation in gain of each of the first antenna 701 and the second antenna 702 within the electronic device 700 .

[0049] At the same time, return to reference Figure 2 After transmitting the first signal through the first antenna 221 in the first time interval and receiving the first reflected signal about the first signal through the second antenna 222 to the fifth antenna 225, the processor 120 may control the switch 230 to switch the path connected to the second antenna 222 from the second Rx path 212 to the second Tx path 202. For example, the processor 120 may control the switch 230 to switch from the second Rx path 212 to the second Tx path 202 before or in the second time interval. The processor 120 may turn on the second PA 242 in the second Tx path 202 electrically connected to the second antenna 222 based on the control of the switch 230. The processor 120 may transmit the second signal through the second antenna 222 in the second time interval, and receive the second reflected signal about the second signal through the third antenna 223 to the fifth antenna 225 based on the turning on of the second PA 242. For example, the processor 120 may control the switch 230 to switch from the second Rx path 212 to the second Tx path 202 before or in the second time interval. The processor 120 may turn on the second PA 242 in the second Tx path 202 electrically connected to the second antenna 222 based on the turning on of the second PA 242. The processor 120 may transmit the second signal through the second antenna 222 in the second time interval, and receive the second reflected signal about the second signal through the third antenna 223 to the fifth antenna 225. Figure 8 2 is described to illustrate that the path connected to the second antenna 222 is switched from the Rx path to the Tx path using the switch 230. Figure 8 An exemplary method of switching a path connected to an antenna in a radar system from a reception path (Rx path) to a transmission path (Tx path) using a switch according to an embodiment is shown.

[0050] For example, refer to Figure 8, the graph 800 indicates the states of the first PA 241 and the second PA 242, the graph 830 indicates the state of the switch 230, and the graph 860 indicates the states of the transmission of the first signal, the reception of the first reflected signal, the transmission of the second signal, and the reception of the second reflected signal. For example, the horizontal axis of the graph 800 indicates time, the vertical axis of the graph 800 indicates the voltage applied to each of the first PA 241 and the second PA 242, the horizontal axis of the graph 830 indicates time, and the vertical axis of the graph 830 indicates the voltage applied to control the switch 230, the horizontal axis of the graph 860 indicates time, and the vertical axis of the graph 860 indicates the frequency of the first signal, the first reflected signal, the second signal, and the second reflected signal.

[0051] The processor 120 may transmit a first signal 812 through the first antenna 221 based on turning on the first PA 241 in the first Tx path 201 during a time 811 in the first time interval 810, while the second antenna 222 is electrically connected to the second Rx path 212 through the switch 230. The processor 120 may receive a first reflection signal 813 regarding the first signal 812 through the second antenna 222 to the fifth antenna 225 in the first time interval 810. In response to receiving the first reflection signal 813, the processor 120 may control the switch 230 to electrically disconnect the second Rx path 212 from the second antenna 222 and electrically connect the second antenna 222 to the second Tx path 202 during a time 814 in the first time interval 810. The processor 120 may transmit a second signal 822 through the second antenna 222 based on turning on the second PA 242 in the second Tx path 202 during a time 821 in the second time interval 820 based on the control of the switch 230. The processor 120 may receive a second reflected signal 823 regarding the second signal 822 through the third antenna 223 to the fifth antenna 225 in the second time interval 820 .

[0052] Figure 8 An example in which the control of the switch 230 is executed (or performed) in the first time interval 810 is shown, but the control of the switch 230 may be performed in another time interval different from the first time interval 810. For example, a separate time interval ( 820 ) between the first time interval 810 and the second time interval 820 may be used. Figure 8 For another example, the control of the switch 230 may be performed within the second time interval 820 before turning on the second PA 242. However, it is not limited thereto.

[0053] At the same time, the processor 120 may send a first signal 812 through the first antenna 221 in the first time interval 810, receive a first reflected signal 813 through the second antenna 222 to the fifth antenna 225, send a second signal 822 through the second antenna 222 in the second time interval 820, and receive a second reflected signal 823 through the third antenna 223 to the fifth antenna 225, so as to form a virtual antenna array. For example, the virtual antenna array may be Fig. 9 . Fig. 9 An example of a virtual antenna array formed using a radar system in an electronic device according to an embodiment is shown.

[0054] For example, refer to Fig. 9 , the processor 120 may send a first signal 812 through the first antenna 221 in the first time interval 810, and receive a first reflected signal 813 through the second antenna 222 to the fifth antenna 225, so as to form a first virtual antenna 910, a second virtual antenna 920, a third virtual antenna 930, and a fourth virtual antenna 940 in the virtual antenna array 900. The processor 120 may send a second signal 822 through the second antenna 222 in a second time interval 820 after the first time interval 810, and receive a second reflected signal 823 through the third antenna 223 to the fifth antenna 225, so as to form a fifth virtual antenna 950, a sixth virtual antenna 960, and a seventh virtual antenna 970 in the virtual antenna array 900.

[0055] Return to reference Figure 1 , the electronic device 101 may include at least one antenna, such as the second antenna 222 electrically connected to the second Tx path 202 or the second Rx path 212 through the switch 230. For example, the electronic device 101 may include at least one antenna connectable to the Tx path or the Rx path in the IC 150 through at least one switch in the IC 150 in various arrangements, at least one antenna connected to at least one other Tx path in the IC 150, and at least one antenna connected to at least one other Rx path in the IC 150, so as to form a virtual antenna array including virtual antennas in various arrangements. Figures 10 to 12 Description is provided to illustrate various arrangements. Figures 10 to 12 An example of a virtual antenna array formed using a radar system in an electronic device according to an embodiment is shown.

[0056] For example, refer to Fig.10, the electronic device 101 includes the first antenna 1001 to the fourth antenna 1004 in the antenna array 160 respectively connected to the first Tx path to the fourth Tx path in the IC 150, the fifth antenna 1005 to the seventh antenna 1007 in the antenna array 160 respectively connected to the first Rx path to the third Rx path in the IC 150, and the eighth antenna 1008 in the antenna array 160 that can be connected to the fifth Tx path or the fourth Rx path in the IC 150 through the switch in the IC 150. For example, the first antenna 1001 to the fourth antenna 1004 can be arranged in the first direction 1011 at the same interval, and the fourth antenna 1004 to the eighth antenna 1008 can be arranged in the second direction 1012 at the same interval. In an embodiment, when the eighth antenna 1008 is connected to the fourth Rx path through the switch, the processor 120 may send a first signal through the first antenna 1001 in a first time interval, receive a first reflected signal about the sent first signal through the fifth antenna 1005 to the eighth antenna 1008, send a second signal through the second antenna 1002 in a second time interval after the first time interval and receive a second reflected signal about the sent second signal through the fifth antenna 1005 to the eighth antenna 1008, and send a second signal through the third antenna 1003 in a third time interval after the second time interval. The invention relates to a method for transmitting and receiving a third signal and receiving a third reflected signal about the transmitted third signal through the fifth antenna 1005 to the eighth antenna 1008, transmitting a fourth signal through the fourth antenna 1004 in a fourth time interval after the third time interval and receiving a fourth reflected signal about the transmitted fourth signal through the fifth antenna 1005 to the eighth antenna 1008, transmitting a fifth signal through the eighth antenna 1008 connected to the fifth Tx path through the switch in a fifth time interval after the fourth time interval, and receiving a fifth reflected signal about the transmitted fifth signal through the fifth antenna 1005 to the seventh antenna 1007. For example, the virtual antenna array 1030 may be formed based on transmission and reception in the first time interval, transmission and reception in the second time interval, transmission and reception in the third time interval, transmission and reception in the fourth time interval, and transmission and reception in the fifth time interval. For example, since the virtual antenna array 1030 includes virtual antennas arranged in a first direction 1011 corresponding to the horizontal direction and a second direction 1012 corresponding to the vertical direction, the electronic device 101 can provide both azimuth resolution and elevation resolution using the antenna array 160 including the first antenna 1001 to the eighth antenna 1008. For example, since the electronic device 101 uses the antenna array 160 including eight antennas (e.g., the first antenna 1001 to the eighth antenna 1008) to form a virtual antenna array 1030 including 19 virtual antennas, the electronic device 101 can provide a greater signal-to-noise ratio (SNR).

[0057] For example, refer to Fig.11The electronic device 101 may include a first antenna 1101 in the antenna array 160 connected to a first Tx path in the IC 150, a second antenna 1102 in the antenna array 160 connected to a first Rx path in the IC 150, and a third antenna 1103 in the antenna array 160 connected to a second Rx path, a fourth antenna 1104 connectable to the second Tx path or the third Rx path in the IC 150 via a first switch in the IC 150, a fifth antenna 1105 connectable to the third Tx path or the fourth Rx path in the IC 150 via a second switch in the IC 150, a sixth antenna 1106 connectable to the fourth Tx path or the fifth Rx path in the IC 150 via a third switch in the IC 150, and a seventh antenna 1107 connectable to the fifth Tx path or the sixth Rx path in the IC 150 via a fourth switch in the IC 150. For example, the first antenna 1101, the fourth antenna 1104, the second antenna 1102, and the fifth antenna 1105 are arranged at the same interval in the first direction 1111, and the sixth antenna 1106, the second antenna 1102, the third antenna 1103, and the seventh antenna 1107 may be arranged at the same interval in the second direction 1112. In an embodiment, the processor 120 may send a first signal through the first antenna 1101 in a first time interval, and receive a first reflected signal about the first signal through at least a portion of the other antennas in the antenna array 160, send a second signal through the fourth antenna 1104 connected to the second Tx path through the first switch in a second time interval after the first time interval, and receive a second reflected signal about the second signal through at least a portion of the antennas other than the first antenna 1101 and the fourth antenna 1104 among the multiple antennas in the antenna array 160, send a third signal through the fifth antenna 1105 connected to the third Tx path through the second switch in a third time interval after the second time interval, and receive a second reflected signal about the second signal through at least a portion of the antennas other than the first antenna 1101 and the fourth antenna 1104 among the multiple antennas in the antenna array 160 At least a portion of antennas other than antenna 1101 and the fifth antenna 1105 receive a third reflected signal regarding the third signal, and in a fourth time interval after the third time interval, a fourth signal is sent through the sixth antenna 1106 connected to the fourth Tx path through the third switch, and a fourth reflected signal regarding the fourth signal is received through at least a portion of antennas other than the first antenna 1101 and the sixth antenna 1106 among the multiple antennas, a fifth signal is sent through the seventh antenna 1107 connected to the fifth Tx path through the fourth switch in a fifth time interval after the fourth time interval, and a fifth reflected signal regarding the fifth signal is received through at least a portion of the other antennas other than the first antenna 1101 and the seventh antenna 1107 among the multiple antennas.For example, the virtual antenna array 1130 may be formed based on transmission and reception in a first time interval, transmission and reception in a second time interval, transmission and reception in a third time interval, transmission and reception in a fourth time interval, and transmission and reception in a fifth time interval. For example, since the virtual antenna array 1130 includes virtual antennas arranged in a first direction 1111 corresponding to the horizontal direction and a second direction 1112 corresponding to the vertical direction, the electronic device 101 can use the antenna array 160 including the first antenna 1101 to the seventh antenna 1107 to provide both azimuth resolution and elevation resolution. For example, since the electronic device 101 forms a virtual antenna array 1130 including 18 virtual antennas by using the antenna array 160 including seven antennas (e.g., the first antenna 1101 to the seventh antenna 1107), the electronic device 101 can provide a greater signal-to-noise ratio.

[0058] For example, refer to Fig.12The electronic device 101 may include a first antenna 1201 in the antenna array 160 connected to a first Tx path in the IC 150, a second antenna 1202 in the antenna array 160 connected to a first Rx path in the IC 150, and a third antenna 1203 in the antenna array 160 connected to a second Rx path, a fourth antenna 1204 in the antenna array 160 connected to a second Tx path or a third Rx path in the IC 150 via a first switch in the IC 150, a fifth antenna 1205 in the antenna array 160 connected to a third Tx path or a fourth Rx path in the IC 150 via a second switch in the IC 150, a sixth antenna 1206 in the antenna array 160 connected to a fourth Tx path or a fifth Rx path in the IC 150 via a third switch in the IC 150, and a seventh antenna 1207 in the antenna array 160 connected to a fifth Tx path or a sixth Rx path in the IC 150 via a fourth switch in the IC 150. For example, the first antenna 1201 to the seventh antenna 1207 in the antenna array 160 may be included in the electronic device 101 in an arrangement corresponding to the shape (e.g., circular) of the display 140 of the electronic device 101 including a smart watch (e.g., smart watch 651). For example, the fourth antenna 1204, the fifth antenna 1205, and the first antenna 1201 are arranged at the same interval in the first direction 1211, and the sixth antenna 1206, the second antenna 1202, the fifth antenna 1205, the third antenna 1203, and the seventh antenna 1207 may be arranged at the same interval in the second direction 1212.In an embodiment, the processor 120 may send a first signal through the first antenna 1201 in a first time interval, and receive a first reflected signal about the first signal through at least a portion of other antennas in the antenna array 160, send a second signal through the fourth antenna 1204 connected to the second Tx path through the first switch in a second time interval after the first time interval, and receive a second reflected signal about the second signal through at least a portion of antennas other than the first antenna 1201 and the fourth antenna 1204 among the multiple antennas in the antenna array 160, send a third signal through the fifth antenna 1205 connected to the third Tx path through the second switch in a third time interval after the second time interval, and receive a second reflected signal about the second signal through at least a portion of antennas other than the first antenna 1201 and the fourth antenna 1204 among the multiple antennas in the antenna array 160. The fourth signal is transmitted through the sixth antenna 1206 connected to the fourth Tx path through the third switch in a fourth time interval after the third time interval, and the fourth reflected signal is received through at least a portion of the antennas except the first antenna 1201 and the sixth antenna 1206 among the plurality of antennas, and the fifth signal is transmitted through the seventh antenna 1207 connected to the fifth Tx path through the fourth switch in a fifth time interval after the fourth time interval, and the fifth reflected signal is received through at least a portion of the other antennas except the first antenna 1201 and the seventh antenna 1207 among the plurality of antennas. For example, the virtual antenna array 1230 may be formed based on transmission and reception in the first time interval, transmission and reception in the second time interval, transmission and reception in the third time interval, transmission and reception in the fourth time interval, and transmission and reception in the fifth time interval. For example, since the virtual antenna array 1230 includes virtual antennas arranged in a first direction 1211 corresponding to the horizontal direction and a second direction 1212 corresponding to the vertical direction, the electronic device 101 can use the antenna array 160 including the first antenna 1201 to the seventh antenna 1207 to provide both azimuth resolution and elevation resolution. For example, since the electronic device 101 uses the antenna array 160 including seven antennas (e.g., the first antenna 1201 to the seventh antenna 1207) to form a virtual antenna array 1230 including 17 virtual antennas, the electronic device 101 can provide a greater signal-to-noise ratio. For example, the electronic device 101 can provide a greater signal-to-noise ratio by using seven antennas arranged to fit the shape of the display 140 within the electronic device 101.

[0059] At the same time, reference Figure 1 In an embodiment, the electronic device 101 may include a switch for reducing the number of Tx paths in the IC 150. For example, Fig.13 Description to illustrate the switch. Fig.13Other examples of the configuration of the radar system in the electronic device according to the embodiment are shown.

[0060] For example, refer to Fig.13 , the electronic device 101 may include an IC 150 and an antenna array 160, the IC 150 includes a switch 1300, a Tx path 1301 electrically connectable to a first antenna 1311 or a second antenna 1312 through the switch 1300, a first Rx path 1321 electrically connected to a third antenna 1313, a second Rx path 1322 electrically connected to a fourth antenna 1314, and a third Rx path 1323 electrically connected to a fifth antenna 1315, and the antenna array 160 includes a first antenna 1311, a second antenna 1312, a third antenna 1313, a fourth antenna 1314, and a fifth antenna 1315. In an embodiment, the Tx path 1301 may include a PA 1341 for setting a Tx power of a first signal transmitted through the first antenna 1311 or a Tx power of a second signal transmitted through the second antenna 1312. In an embodiment, the first Rx path 1321 may include a first LNA 1351 for amplifying power of a signal (eg, a first reflected signal regarding the first signal and a second reflected signal regarding the second signal) received through the third antenna 1313. Fig.13 , but the first Rx path 1321 may also include a first mixer and a first filter. However, it is not limited thereto. In an embodiment, the second Rx path 1322 may include a second LNA 1352 for amplifying the power of a signal (e.g., a first reflected signal about the first signal and a second reflected signal about the second signal) received through the fourth antenna 1314. Although not shown in Fig.13 , but the second Rx path 1322 may also include a second mixer and a second filter. However, it is not limited thereto. In an embodiment, the third Rx path 1323 may include a third LNA 1353 for amplifying the power of a signal (e.g., a first reflected signal about the first signal and a second reflected signal about the second signal) received through the fifth antenna 1315. Although not shown in Fig.13 , but the third Rx path 1323 may also include a third mixer and a third filter. However, it is not limited thereto.

[0061] In an embodiment, the processor 120 may transmit a first signal through the first antenna 1311 electrically connected to the Tx path 1301 through the switch 1300 in a first time interval (e.g., a first frame). The processor 120 may receive a first reflected signal in which the first signal is reflected from an external object around the electronic device 101 through the third antenna 1313 to the fifth antenna 1315 in the first time interval.
