Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/KR2022/000852 designating the United States, filed on Jan. 17, 2022, in the Korean Intellectual Property Receiving Office and claiming priority to Korean Patent Application No. 10-2021-0009914, filed on Jan. 25, 2021, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties. 
    
    
     BACKGROUND 
     Field 
     The disclosure relates to an antenna switching method and an electronic device. 
     Description of Related Art 
     In line with development of wireless communication technologies, electronic devices (for example, electronic devices for communication) are widely used in daily life, and ultra wide band (UWB) communication (for example, super-wide-band communication) has recently been highlighted as a new type of communication technology. An electronic device supporting UWB communication may measure the position of an external electronic device (for example, target device) performing UWB communication, based on a wide bandwidth (for example, about 500 MHz). 
     As a result of establishment of a new IEEE standard referred to as 802.15.4z, an STS (scrambled time stamp) field has been added to UWB communication. Based on the STS field, security of UWB communication has been improved, and the same may be used for position measurement regarding the electronic device and the external electronic device in a safer manner. 
     UWB communication (for example, super-wide-band communication) is a short-range high-speed communication, and supports high-speed communication in short ranges, but has limitations due to low transmission power levels. UWB communication, which is based on high frequency bands (for example, about 6-8 GHz), has lower diffraction characteristics and stronger straightness than lower frequency bands, and thus may be heavily affected by obstacles. When an electronic device having an antenna supporting UWB communication performs UWB communication, a shaded area having degraded UWB communication quality may occur. An electronic device supporting UWB communication may include multiple different antennas having different polarization characteristics, and may switch the multiple antennas, thereby improving the performance of UWB communication. 
     SUMMARY 
     Various embodiments of the disclosure may provide a method for switching antennas in order to improve the performance of UWB communication in connection with an electronic device including multiple antennas supporting UWB communication, and an electronic device for implementing the same. 
     An electronic device according to various example embodiments may include: a communication module comprising communication circuitry, a first antenna having a first polarization characteristic, a second antenna having a second polarization characteristic different from the first polarization characteristic, a switch operatively connected to the communication module, the first antenna, and the second antenna, and a processor operatively connected to the first antenna and the second antenna through the switch. The processor may be configured to: identify, based on transmitting at least one packet using the first antenna, at least one timestamp of the packet, control the electronic device to transmit a first area of the packet using the first antenna based on a first timestamp of the identified timestamps, switch from the first antenna to the second antenna based on a second timestamp of the identified timestamps, and control the electronic device to transmit a second area of the packet using the second antenna based on the second timestamp of the packet. 
     A method of operating an electronic device according to various example embodiments may include: identifying, based on transmitting at least one packet using a first antenna having a first polarization characteristic, at least one timestamp of the packet, transmitting a first area of the packet using the first antenna based on a first timestamp of the identified timestamp, switching from the first antenna to a second antenna having an characteristic different from that of the first antenna based on a second timestamp of the identified timestamp, and transmitting a second area of the packet using the second antenna based on the second timestamp of the packet. 
     According to various example embodiments of the disclosure, in connection with an electronic device including multiple antennas having different polarization characteristics (for example, metal antenna, laser direct structuring (LDS) antenna, and/or patch antenna), UWB communication may be performed by switching the multiple antennas. In order to improve the performance of UWB communication, according to various example embodiments, a first antenna and a second antenna which have different polarization characteristics may be switched. 
     According to various example embodiments of the disclosure, an electronic device may perform UWB communication by switching a first antenna and a second antenna which have different polarization characteristics, and may maintain the performance of UWB communication in wider areas. Various other advantageous effects identified explicitly or implicitly through the disclosure may be provided.

     The communication module  190  may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device  101  and the external electronic device (e.g., the electronic device  102 , the electronic device  104 , or the server  108 ) and performing communication via the established communication channel. The communication module  190  may include one or more communication processors that are operable independently from the processor  120  (e.g., the AP) and supports a direct (e.g., wired) communication or a wireless communication. The communication module  190  may include a wireless communication module  192  (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module  194  (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network  198  (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or a standard of the Infrared Data Association (IrDA)) or the second network  199  (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module  192  may identify and authenticate the electronic device  101  in a communication network, such as the first network  198  or the second network  199 , using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the SIM  196 .

All or some of operations to be executed at the electronic device  101  may be executed at one or more of the external electronic devices  102 ,  104 , or  108 . For example, if the electronic device  101  should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device  101 , instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device  101 . The electronic device  101  may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request.

       FIG. 2  is a perspective view of an electronic device including multiple antennas according to various embodiments. 
     Referring to  FIG. 2 , an electronic device (for example, electronic device  101  in  FIG. 1 ) may include multiple antenna modules (for example, the antenna module  197  in  FIG. 1 ) supporting ultra wide band communication. For example, the electronic device  101  may include a first antenna  201  disposed adjacent to a surface (for example, a lateral surface) rather than a front surface and/or a rear surface, and a second antenna  202  disposed adjacent to the rear surface. For example, the first antenna  201  may radiate a wireless communication signal corresponding to Y direction  223  with reference to the electronic device  101  and the second antenna  202  may radiate a wireless communication signal corresponding to a rear surface direction (for example, −Z direction  221 ) with reference to the electronic device  101 . According to an embodiment, the first antenna  201  and the second antenna  202  may be disposed at a lateral surface of the electronic device  101  and a rear surface of the electronic device  101 , respectively, and may be disposed to radiate wireless communication signals based on different directions. According to an embodiment, the first antenna  201  and the second antenna  202  may be disposed at the same surface (for example, a front surface, rear surface, and/or lateral surface), and may radiate wireless communication signals having different polarization characteristics. 
     According to an embodiment, the first antenna  201  and the second antenna  202  may be disposed at different height, different positions, and/or different planes. According to an embodiment, the first antenna  201  and the second antenna  202  may be implemented in different types of antennas and designed to have at least one different characteristic from among radiation coverage, a polarization characteristic, a radiation pattern, gain, and/or a frequency channel characteristic of an antenna. According to an embodiment, the arrangement positions of the first antenna  201  and the second antenna  202  are not limited to the view of  FIG. 2  and may be designed to include wider radiation coverage (for example, a radiation area and/or a radiation range). According to an embodiment, the first antenna  201  and the second antenna  202  may be electrically connected to a communication module (for example, the communication module  190  in  FIG. 1 ) of the electronic device  101 . 
     According to an embodiment, the first antenna  201  and the second antenna  202  may be formed in different types of antennas or in a single antenna. For example, the first antenna  201  may include a metal antenna of which at least a portion is formed of a metal material and/or a laser direct structuring (LDS) antenna of which at least a portion has a metal pattern designed thereon. According to an embodiment, the first antenna  201  may be designed to radiate a wireless communication signal, based on a first polarization direction (for example, Y direction  223 ). For example, the second antenna  202  may include a UWB antenna supporting wideband communication (for example, a UWB communication) and may include one or more patch antennas designed to measure a position with respect to an external electronic device (for example, a target device). According to an embodiment, the second antenna  202  may be designed to radiate a wireless communication signal, based on a second polarization direction (for example, −Z direction  221 , rear surface direction). According to an embodiment, the second antenna  202  may be designed to radiate a wireless communication signal, based on a third polarization direction (for example, Z direction  222 , front surface direction). According to an embodiment, the second antenna  202  may be designed to have substantially the same radiation performance in response to −Z direction  221  (for example, a second polarization direction) and/or Z direction  222  (for example, a third polarization direction). According to an embodiment, the electronic device  101  may measure an angle of arrival (AoA) for an external electronic device using the second antenna  202  and may determine, based on the measured AoA value, a position of the external electronic device. 
     According to an embodiment, the electronic device  101  including different types of antennas (for example, the first antenna  201  and/or the second antenna  202 ) may transmit and receive at least one packet upon performing wireless communication with another external electronic device. When transmitting at least one packet, the electronic device  101  may identify a timestamp (for example, a first timestamp and/or a second timestamp). The electronic device  101  may separate one packet into a first packet area and/or a second packet area, and transmit the same, based on the identified timestamp (for example, a first timestamp). For example, the electronic device  101  may select at least one antenna (for example, the first antenna  201 ) at the identified first timestamp and transmit the first packet area using the selected first antenna  201 . The electronic device  101  may select at least one antenna (for example, the second antenna  202 ) at a timestamp (for example, a second timestamp) when the first packet transmission is completed, and transmit the second packet area using the selected second antenna  202 . According to an embodiment, the electronic device  101  may perform a switching operation to select the first antenna  201 , based on the first timestamp, and perform a switching operation to select the second antenna  202 , based on the second timestamp. 
     According to an embodiment, the electronic device  101  may transmit the first packet area through the first antenna  201  at the first timestamp, and transmit the second packet area through the second antenna  202  at the second timestamp. According to an embodiment, the first antenna  201  and the second antenna  202  may be implemented to have different characteristics (for example, radiation coverage, polarization performance, a radiation pattern, a radiation direction, gain, and/or a frequency channel characteristic). According to an embodiment, the electronic device  101  may perform ultra wide band wireless communication (for example, UWB communication) with an external electronic device, based on a wider radiation coverage.

The antenna module  197  may include a first antenna  201  (for example, the first antenna  201  in  FIG. 2 ) and/or a second antenna  202  (for example, the second antenna  202  in  FIG. 2 ), and may include an UWB antenna supporting an ultra wide band communication method (for example, ultra wide band (UWB) communication). For example, the first antenna  201  and/or the second antenna  202  may be implemented to have different characteristics (for example, radiation coverage, polarization performance, a radiation pattern, a radiation direction, gain, and/or a frequency channel characteristic). For example, the first antenna  201  may include a metal antenna and the second antenna  202  may include a patch antenna. 
     According to an embodiment, the first antenna  201  and the second antenna  202  may have polarization characteristics by combining two components of polarization and may be designed to have different characteristics. For example, the first antenna  201  may have a polarization characteristic, based on an H component (horizontal) (for example, an H-pol characteristic) and the second antenna  202  may have a polarization characteristic, based on a V component (vertical) (for example, a V-pol characteristic). The first antenna  201  may perform wireless communication based on the H component and the second antenna  202  may perform wireless communication based on the V component.

For example, when the difference value is smaller than the predetermined (e.g., specified) threshold value, the processor  120  may perform wireless communication with an external electronic device through the first antenna  201 . For example, when the difference value is larger than the predetermined (e.g., specified) threshold value, the processor  120  may switch from the first antenna  201  to the second antenna  202 , and may perform wireless communication with an external electronic device through the switched second antenna  202 . According to an embodiment, the processor  120  may compare and analyze at least one piece of data related to wireless communication with an external electronic device and may select at least one antenna for improving the wireless communication quality (for example, performance), based on the at least one piece of data.

The first antenna  201  may include a metal antenna of which at least a portion is formed of a metal material and/or a laser direct structuring (LDS) antenna of which at least a portion has a metal pattern designed thereon. For example, the first antenna  201  may be connected to a conductive member which is at least partially exposed outside through the housing of the electronic device  101 . The first antenna  201  may be designed to radiate a communication signal in the first polarization direction (for example, Y direction in  FIG. 2 ). For example, using the first antenna  201 , the electronic device  101  may perform UWB communication in a direction parallel with the X axis or perpendicular to the Y axis in  FIG. 2 . 
     According to an embodiment, the second antenna  202  may include a UWB antenna supporting wideband communication (for example, UWB communication) and may include one or more patch antennas designed to measure a position with respect to an external electronic device. According to an embodiment, the second antenna  202  may include multiple patch antennas and measure a distance from an external electronic device and an angle with an external electronic device.

According to an embodiment, when transmitting a packet for wireless communication, the electronic device  101  may identify at least one timestamp (for example, a first timestamp and/or a second timestamp) corresponding to the packet and switch an antenna based on the timestamp. For example, the electronic device  101  may separate a first packet area and a second packet area, based on the first timestamp, and transmit the first packet area using the first antenna  201  and the second packet area using the second antenna  202 . According to an embodiment, the electronic device  101  may perform, based on the first timestamp, switching to one of the first antenna  201  and the second antenna  202 .

For example, the first patch antenna  401  and the second patch antenna  402  may be designed to be arranged based on the vertical direction (for example, Y direction in  FIG. 2 ) of the electronic device  101 . The first patch antenna  401  and a third patch antenna (not shown) may be designed to be arranged based on the horizontal direction (for example, X direction in  FIG. 2 ) of the electronic device  101 . For example, the second patch antenna  402  may be disposed spaced apart by a configured distance (for example, the distance D  431 ) in the vertical direction with reference to the first patch antenna  401 , and the third patch antenna (not shown) may be disposed spaced apart by a configured distance (for example, a distance D  431 ) in the horizontal direction with reference to the first patch antenna. 
     According to an embodiment, when performing UWB communication, the electronic device  101  may perform UWB communication in, for example, one of two operation modes (for example, a portrait mode (or vertical mode) and/or a landscape mode (or horizontal mode)).

       FIG. 6  is a flowchart illustrating an example method for switching antennas based on a first antenna and a second antenna having different polarization characteristics according to various embodiments. 
     According to various embodiments, an electronic device  101  (for example, the electronic device  101  in  FIG. 1 ) may include multiple antennas (for example, a first antenna (for example, the first antenna  201  in  FIG. 2 ) and/or a second antenna (for example, the second antenna  202  in  FIG. 2 ) having different polarization characteristics and supporting ultra wide band communication. For example, the first antenna  201  may include a metal antenna and/or an LDS antenna, and the second antenna  202  may include one or more patch antennas. According to an embodiment, the first antenna  201  and the second antenna  202  may have polarization characteristics by combining two components of polarization and may be designed to have different characteristics. For example, the first antenna  201  may have a polarization characteristic, based on an H component (horizontal) (for example, an H-pol characteristic) and the second antenna  202  may have a polarization characteristic, based on a V component (vertical) (for example, a V-pol characteristic). According to an embodiment, the first antenna  201  may be designed to have a first polarization direction (for example, +Y to −Y direction in  FIG. 2 ), and the second antenna  202  may be designed to have a second polarization direction (for example, +X to −X direction in  FIG. 2 ). For example, the first polarization direction of the first antenna  201  and the second polarization direction of the second antenna  202  may be perpendicular to each other. According to an embodiment, the first antenna  201  and the second antenna  202  may be designed to complement each other. According to an embodiment, the electronic device  101  may secure a wider range of communication coverage using multiple antennas having different characteristics. 
     According to an embodiment, the electronic device  101  may perform switching between the first antenna  201  and the second antenna  202  to improve UWB communication performance According to an embodiment, when transmitting at least one packet corresponding to a UWB signal, the electronic device  101  may divide at least one packet into multiple packet areas (for example, a first packet area and/or a second packet area), and transmit the first packet area using the first antenna  201  and the second packet area using the second antenna  202 . For example, at least one timestamp (for example, a first timestamp and/or a second timestamp) may be recorded on at least one packet and switching between the first antenna  201  and the second antenna  202  may be performed based on the timestamp. For example, the electronic device  101  may select the first antenna  201  at the first timestamp and transmit the first packet area using the first antenna  201 . The electronic device  101  may select the second antenna  202  at the second timestamp and transmit the second packet area using the second antenna  202 . According to an embodiment, when transmitting at least one packet, the electronic device  101  may perform switching of the first antenna  201  and/or the second antenna  202  at at least one timestamp. 
     In operation  601 , when transmitting at least one packet for wireless communication (for example, ultra wide band (UWB) communication), the electronic device  101  may identify at least one timestamp corresponding to the packet. For example, at least one packet may include multiple fields and data related to UWB communication may be stored in each field. For example, the packet may be implemented with a structure based on IEEE 802.15.4z, an international standard for UWB communication. According to an embodiment, the electronic device  101  may determine at least two fields of multiple fields included in the packet and record a first timestamp (first timestamp) and a second timestamp (second timestamp) in response to each of the determined fields. For example, the electronic device  101  may record a first timestamp (first timestamp), based on the end of a start frame delimiter (SFD) field of multiple fields and record a second timestamp (second timestamp), based on the end of a scrambled timestamp sequence (STS) field of multiple fields. In operation  601 , the processor  120  of the electronic device  101  may identify, when transmitting at least one packet, at least one timestamp (for example, the first timestamp and/or the second timestamp) corresponding to the at least one packet. 
     In operation  603 , the processor  120  may separate the at least one packet into a first packet area and/or a second packet area, based on the identified timestamp. For example, when transmitting at least one packet, the processor  120  may separate the first packet area transmitted at the first timestamp and/or the second packet area transmitted at the second timestamp. The processor  120  may transmit the first packet area at the first timestamp and then transmit the second packet area at the second timestamp. According to an embodiment, the processor  120  may perform an antenna switching operation using gap fields before/after the first timestamp as a reference. For example, the processor  120  my select the first antenna  201  with reference to the first timestamp and the second antenna  202  with reference to the second timestamp. 
     In operation  605 , the processor  120  may transmit the first packet area based on the first timestamp using the first antenna  201  having the first polarization characteristic. For example, the process  120  may select the first antenna  201  of the first antenna  201  and the second antenna  202  at the first timestamp as a reference point and transmit the first packet area at the first timestamp using the first antenna  201 . 
     In operation  607 , the processor  120  may perform, based on the second timestamp, switching from the first antenna  201  to the second antenna  202 . For example, the second timestamp may be recorded with reference to the end of the STS field included in the packet. The processor  120  may identify a gap at least partially formed in a field next to the STS field, and perform a switching operation from the first antenna  201  to the second antenna  202  based on the gap field. For example, a gap field may be at least partially formed between the STS field and the next field. 
     In operation  609 , the processor  120  may transmit the second packet area based on the second timestamp using the second antenna  202  having the second polarization characteristic different from the first polarization characteristic. For example, the first antenna  201  and/or the second antenna  202  may be implemented to have different characteristics (for example, radiation coverage, polarization performance, a radiation pattern, a radiation direction, gain, and/or a frequency channel characteristic). According to an embodiment, the first polarization characteristic may be implemented to be perpendicular to the second polarization characteristic. For example, as shown in  FIG. 2 , the first polarization characteristic may be designed to have a first polarization direction corresponding to +Y to −Y direction, and the second antenna  202  may be designed to have a second polarization direction corresponding to +X to −X direction. According to an embodiment, the first antenna  201  and the second antenna  202  may be designed to complement each other. According to an embodiment, the electronic device  120  may transmit the first packet area at the first timestamp using the first antenna  201 , and transmit the second packet area at the second timestamp using the second antenna  202 . 
     According to an embodiment, the electronic device  101  may perform switching between the first antenna  201  and the second antenna  202  having different characteristics to transmit at least one packet so as to improve UWB communication performance. For example, at least one packet may be separated into a first packet area and a second packet area, based on at least one timestamp. The electronic device  101  may transmit the first packet area using the first antenna  201 , and transmit the second packet area using the second antenna  202 . 
     According to an embodiment, although not shown, the electronic device  101  may transmit at least one packet to an external electronic device and then receive, from the external electronic device, a response signal in response to the transmitted at least one packet. According to an embodiment, the electronic device  101  may perform a positioning operation (for example, an AoA measuring operation) with respect to the external electronic device based on the timestamp at which the at least one packet is transmitted to the external electronic device and the timestamp at which the response signal is received form the external electronic device. According to an embodiment, the electronic device  101  may separate one packet divided into a first packet area and a second packet area and transmit the same, and may respectively receive response signals in response to the first packet area and the second packet area from the external electronic device. According to an embodiment, the external electronic device may be implemented to transmit, to the electronic device  101 , response signals in response to the reception of at least one of the first packet area and/or the second packet area, respectively. For example, in response to the reception of the first packet area, the external electronic device may transmit a first response signal to the electronic device  101  and in response to the reception of the second packet area, the external electronic device may transmit a second response signal to the electronic device  101 . According to an embodiment, the electronic device  101  may perform a positioning operation with respect to the external electronic device based on the packet signal (for example, the first packet area and/or the second packet area) transmitted to the external electronic device and the response signal received from the external electronic device.
