[0049] Figure 2 This is a block diagram of an electronic device according to an embodiment.

[0050] According to one embodiment, electronic device 200 (e.g., Figure 1 The electronic device 101 may include a communication circuit 210 (e.g., Figure 1 The communication module 190) and the memory 220 (e.g., Figure 1 The memory 130) and the processor 230 (e.g., Figure 1 The processor 120).

[0051] According to one embodiment, the communication circuit 210 can communicate with external electronic devices (e.g., under the control of the processor 230 or independently) Figure 1 The electronic device 102 performs wireless communication (e.g., Wi-Fi communication, ultra-wideband (UWB) communication, and / or Bluetooth (BT) communication). According to one embodiment, the communication circuit 210 may consist of modules or chipsets partitioned for each communication scheme. For example, the communication circuit 210 may include a Wi-Fi module, a UWB module, and / or a BT module.

[0052] According to one embodiment, the communication circuit 210 may include at least one antenna 211. For example, the communication circuit 210 may include multiple antennas 211 corresponding to different communication schemes or different frequency bands, and may include one antenna 211 supporting various communication schemes and / or various frequency bands. According to one embodiment, the communication circuit 210 may include variable circuitry for controlling the characteristics of at least one antenna 211. According to one embodiment, the variable circuitry may include at least one switch and / or lumped component. According to one embodiment, under the control of the processor 230, at least one antenna 211 can be adjusted in frequency band characteristics.

[0053] According to one embodiment, memory 220 may store at least one program, application, data, or instruction executed by processor 230. According to one embodiment, memory 220 may store information required for performing communication. For example, memory 220 may store information about supported communications (e.g., Wi-Fi, Bluetooth, and / or UWB), supported communication frequency band information (e.g., Wi-Fi communication band or UWB communication band), and / or information about the external electronic device performing the communication (e.g., Service Set Identifier (SSID)). According to one embodiment, memory 220 may store information required for controlling antenna 211. For example, memory 220 may store information about the frequency bands supported by antenna 211, data for adjusting the characteristics of antenna 211, and / or information about the characteristics or gain of antenna 211, depending on the communication state.

[0054] According to one embodiment, processor 230 can identify the connection status of a communication channel. For example, processor 230 can identify whether the current connection status of the communication channel is a state of scanning a Wi-Fi communication channel or a state of determining a Wi-Fi communication channel. According to one embodiment, scanning the state of a communication channel can include at least one of the following: a communication channel scanning state for searching for at least one external electronic device 200 (e.g., an access point) to perform Wi-Fi communication, a communication channel scanning state for indoor positioning of the electronic device 200, or a communication channel scanning state for roaming settings of the electronic device 200. For example, processor 230 can receive signal strength and / or location information of external electronic devices 200 (e.g., access points) present around the electronic device 200 based on a specified time or specified conditions for indoor positioning. According to one embodiment, the specified conditions can include GPS signal strength, a specified location, a specified time period, and / or changes in the values ​​of at least one sensor included in the electronic device 200. For example, processor 230 can perform operations similar to scanning external electronic devices 200 to substantially determine a Wi-Fi communication channel for indoor positioning. For example, processor 230 can receive information about surrounding external electronic devices 200 for roaming settings and can perform operations similar to scanning for external electronic devices 200 to substantially determine Wi-Fi communication channels. According to one embodiment, when communication conditions deteriorate (e.g., when communication quality drops to a specified level or lower) while electronic device 200 is performing Wi-Fi communication with a specific external electronic device 200 (e.g., an access point), processor 230 can switch electronic device 200 to a state of scanning communication channels to search for new external electronic devices 200 (e.g., new access points). According to various embodiments, processor 230 can switch electronic device 200 to a state of scanning communication channels based on a user request or a system request. For example, when a user is running a specified application (e.g., an indoor positioning application), processor 230 can switch to a state of scanning communication channels based on the communication connectivity status of electronic device 200.

[0055] According to one embodiment, while scanning a Wi-Fi communication channel, the processor 230 can adjust the characteristics of the antenna 211 to broadband characteristics. For example, the processor 230 can adjust the characteristics of the antenna 211 so that the antenna 211 operates in a frequency band including a first Wi-Fi band and a second Wi-Fi band. For example, the first Wi-Fi band may include a 5GHz Wi-Fi band, and the second Wi-Fi band may include a 6GHz Wi-Fi band. According to one embodiment, the processor 230 can use a variable circuit connected to the antenna 211 to adjust the characteristics of the antenna 211. For example, the variable circuit may include at least one switch and / or lumped components (e.g., capacitors, inductors, and / or stubs). For example, the processor 230 can control the switch to electrically connect or disconnect the at least one lumped component from the antenna 211, thereby adjusting the characteristics of the antenna 211. For example, processor 230 can use antenna 211 with broadband characteristics (e.g., approximately 5.15 GHz to 7.125 GHz band characteristics) to scan communication channels across the entire range, including the 5 GHz Wi-Fi band and the 6 GHz Wi-Fi band. For example, processor 230 can set the antenna gain to the level required only for scanning the communication channel, and can increase the operating band of antenna 211 to scan the communication channel in a broadband manner, thereby reducing the power and time consumed in scanning the communication channel.

[0056] According to one embodiment, when a Wi-Fi communication channel is determined, the processor 230 can adjust the characteristics of the antenna 211 to narrowband characteristics (e.g., a specified range of frequency bands within the 5.150 GHz to 5.835 GHz band (e.g., 20 MHz, 40 MHz, 80 MHz, or 160 MHz) or a specified range of frequency bands within the 5.925 GHz to 7.125 GHz band). For example, when a communication channel is determined, the processor 230 can perform Wi-Fi communication with a specific external electronic device 200 (e.g., an access point) through the determined communication channel. According to one embodiment, the processor 230 can adjust the characteristics of the antenna 211 so that the antenna 211 operates in the frequency band corresponding to the determined communication channel. For example, the processor 230 can adjust the characteristics of the antenna 211 to a narrowband of the specified frequency band to facilitate smooth communication in the determined communication channel and can increase the gain of the antenna 211 in the specified frequency band. For example, the processor 230 can use an antenna 211 with narrowband characteristics to perform Wi-Fi communication with a designated external electronic device 200 on a determined communication channel. For example, when a communication channel to a specific external electronic device 200 (e.g., an access point) is determined, the processor 230 can perform communication with the corresponding external electronic device 200 through the antenna 211.

[0057] According to one embodiment, processor 230 can determine the communication scheme to be used. For example, when the communication circuitry 210 of electronic device 200 includes a Wi-Fi module (Wi-Fi chipset) and an ultra-wideband (UWB) module (or UWB chipset), processor 230 can receive information associated with each communication state from each of the Wi-Fi module and the UWB module. For example, processor 230 can determine the communication scheme to be used based on the received information. According to one embodiment, when electronic device 200 performs Wi-Fi communication, processor 230 can receive UWB communication-related information from the ultra-wideband (UWB) module. For example, UWB communication-related information may include UWB ranging time-period related information. For example, the frequency band of UWB communication may be at least partially shared with the Wi-Fi communication frequency band (e.g., the 5GHz band and / or the 6GHz band). According to one embodiment, processor 230 can receive UWB communication-related information from at least one communication module. For example, processor 230 can receive UWB communication-related information via a Bluetooth module or a Wi-Fi module. For example, each communication module can exchange information through processor 230, or can directly exchange information and provide information to processor 230.

[0058] According to one embodiment, electronic device 200 can determine to perform UWB communication based on received UWB communication-related information. According to another embodiment, electronic device 200 can process UWB communication-related information with a higher priority than Wi-Fi communication-related information. For example, when UWB communication-related information is received while performing Wi-Fi communication, electronic device 200 can determine to perform UWB communication. According to another embodiment, when Wi-Fi communication-related information is received regarding a specified event (e.g., an emergency event), electronic device 200 can process Wi-Fi communication with a higher priority than UWB communication. For example, the specified event (e.g., an emergency event) may include a telephone call using Wi-Fi communication or an incident notification event. According to another embodiment, processor 230 can control a switch connected to antenna 211 to adjust the characteristics of antenna 211 such that antenna 211 operates in a frequency band including at least a portion of the UWB communication frequency band (e.g., the 5GHz and / or 6GHz band). According to one embodiment, depending on a specified time period based on UWB communication-related information (e.g., UWB ranging time-related information), electronic device 200 can adjust the characteristics of antenna 211 to broadband characteristics to correspond to at least a portion of the UWB communication frequency band. According to one embodiment, processor 230 can perform UWB communication using its characteristic-adjusted antenna 211.

[0059] Figures 3A to 3C The illustrations depict communication connection schemes according to various embodiments.

[0060] According to one embodiment, electronic device 310, 320, or 330 (e.g., Figure 1 Electronic devices 101 or Figure 2 Electronic device 200 can obtain network information from surrounding wireless access points (APs). For example, there are generally active scanning and passive scanning schemes for electronic devices 310, 320, or 330 to obtain network information from APs 350, 360, 370, or 380. For example, an active scanning scheme is where electronic device 310 or 320 sends a probe request (e.g., a probe request frame) and receives a probe response (e.g., a beacon frame) to the probe request sent from APs 350, 360, or 370 to obtain network information. A passive scanning scheme is where electronic device 330 receives beacon frames from surrounding APs 380 to obtain network information.

[0061] For example, refer to Figure 3A The illustration shows an electronic device 310 scanning APs 350 and 360 using an active scanning scheme without specifying a Service Set Identifier (SSID). For example, when configuring a probe request, electronic device 310 may not set the SSID in the probe request frame and may set the SSID field to 0 (empty). For example, electronic device 310 may broadcast the configured probe request. For example, each AP 350 and 360 around electronic device 310 that receives a probe request from electronic device 310 may send a probe response to electronic device 310. For example, electronic device 310 may obtain network information based on the received probe responses.

[0062] For example, refer to Figure 3B Electronic device 320 specifies a particular Service Set Identifier (SSID) and scans AP 370 using an active scanning scheme. For example, electronic device 320 can specify a particular SSID and can send a probe request. For example, when electronic device 320 is configured to access a specified wireless network, has a history of connecting to a specified wireless network, or is already connected to a wireless network, it can set the SSID corresponding to the connected or established wireless network when configuring the probe request. For example, when configuring the probe request, electronic device 320 can set the SSID (AP1) corresponding to the specified AP 370 in the SSID field of the probe request frame. For example, electronic device 320 can unicast a probe request with the specific SSID set to the corresponding AP 370. For example, upon receiving a probe request from electronic device 320, AP 370 can send a probe response to electronic device 320. For example, electronic device 320 can obtain network information based on the received probe response.

[0063] For example, refer to Figure 3CThe illustration shows an electronic device 330 scanning an access point (AP) 380 using a passive scanning scheme. For example, AP 380 may periodically send beacon frames to surrounding devices (e.g., electronic device 330 and external electronic device 340). For example, electronic device 330 may periodically receive beacon frames from surrounding APs 380 and obtain network information based on the received beacon frames.

[0064] When electronic devices 310, 320, or 330 perform scanning operations on all communication channels, power consumption may increase, regardless of whether the scanning scheme is passive or active. According to embodiments of this disclosure, electronic devices 310, 320, or 330 may control the antenna characteristics differently depending on whether the communication channel is being scanned or determined, to perform communication using antenna characteristics suitable for the communication state, thereby reducing unnecessary power consumption and / or time consumption.

[0065] Figure 4A and Figure 4B The illustration shows a Wi-Fi band supported by an electronic device according to one embodiment.

[0066] Reference Figure 4A 410 indicates the frequency bands supported in 2.4 GHz and 5 GHz Wi-Fi communication, and 420 indicates newly allocated frequency bands in Wi-Fi communication. Wi-Fi communication supports the 2.4 GHz and 5 GHz frequency bands (410). However, recently, the 6 GHz frequency band has been allocated as a new Wi-Fi service frequency band (420). Therefore, to support 6 GHz Wi-Fi communication, electronic devices may need to perform operations such as scanning the communication channels of the 6 GHz frequency band as well as scanning the existing communication channels of the 2.4 GHz and 5 GHz frequency bands.

[0067] The newly allocated 6GHz band in Wi-Fi communication has a bandwidth of 1.2GHz, which is relatively wider than the existing 2.4GHz band's 95MHz bandwidth and the 5GHz band's 670MHz to 675MHz bandwidth. Therefore, scanning the entire bandwidth of the Wi-Fi 6GHz band by electronic devices can take a considerable amount of time.

[0068] Reference Figure 4B Illustration 430 shows that only the 2.4GHz and 5GHz bands are supported in Wi-Fi communication, while illustration 440 shows that the newly allocated 6GHz band is supported in Wi-Fi communication.

[0069] Refer to 430, electronic devices (e.g., Figure 1 Electronic devices 101 or Figure 2 The electronic device 200 may include cores corresponding to each of the 2.4 GHz and 5 GHz frequency bands (e.g., Figure 1 Communication module 190 or Figure 2 (Communication circuit 210). For example, when only the 2.4 GHz and 5 GHz bands are available as Wi-Fi bands, the electronic device can simultaneously scan the 2.4 GHz and 5 GHz bands using different cores for each of the 2.4 GHz and 5 GHz bands.

[0070] Reference 440 states that due to the additional allocation of the Wi-Fi 6GHz band, electronic devices (e.g., Figure 1 Electronic devices 101 or Figure 2 Electronic device 200) can support Wi-Fi in the 2.4 GHz, 5 GHz, and 6 GHz frequency bands. Due to space constraints, electronic devices may have limited antenna capacity. Using a single antenna to perform communication between adjacent frequency bands (e.g., the 5 GHz Wi-Fi band and the 6 GHz Wi-Fi band) can facilitate efficient communication. For example, electronic devices can share a core (or antenna) for both the 5 GHz and 6 GHz bands for operation. When electronic devices use the same antenna to cover both the 5 GHz and 6 GHz bands and only use the antenna with specified characteristics (e.g., antenna gain and / or the antenna's operating frequency band), the time and power consumption for scanning the communication channel may increase. Therefore, using only one antenna mode (e.g., one antenna characteristic) may be insufficient to provide effective communication performance across a wide bandwidth frequency domain. According to embodiments of this disclosure, electronic devices can control the antenna characteristics differently depending on whether the communication channel is being scanned or determined, to perform communication using antenna characteristics suitable for the communication state, thereby reducing unnecessary power consumption and / or time consumption. Embodiments of this disclosure will be described in detail below.

[0071] Figure 5A and Figure 5B This is a diagram illustrating the operation of an antenna characteristic in a control electronic device according to one embodiment.

[0072] Reference Figure 5A The illustration shows an electronic device 500 according to one embodiment (e.g., Figure 1 Electronic devices 101 or Figure 2 The available Wi-Fi frequency bands and antenna characteristics (antenna gain) of the electronic device (200). For ease of description, Figure 5A The diagram illustrates the 5GHz and 6GHz Wi-Fi bands, but is not limited to these. Electronic device 500 can perform communication in the 2.4GHz Wi-Fi band.

[0073] According to one embodiment, electronic device 500 can adjust the characteristics of antenna 511 (e.g., antenna gain and / or the antenna's operating frequency band) to have high gain in a relatively narrow frequency band (e.g., 20MHz, 40MHz, 80MHz, or 160MHz bandwidth). For example, electronic device 500 can adjust the characteristics of antenna 511 to have high gain in the 5GHz frequency band, such as Na, Nb, Nc, ..., corresponding to a specific communication channel, and can adjust the characteristics of antenna 511 to have high gain in the 6GHz frequency band, such as N1, N2, N3, ..., corresponding to a specific communication channel. For example, each of Na, Nb, Nc, ... and N1, N2, N3, ... can be set to a bandwidth of 20MHz, 40MHz, 80MHz, or 160MHz. According to one embodiment, electronic device 500 can adjust the characteristics of antenna 511 to wideband characteristic B when the communication channel is scanned, and can scan external electronic devices 500 (e.g., APs). For example, the 2.4GHz band supported in Wi-Fi communication can be the 2.401GHz to 2.495GHz band, the 5GHz band can be the 5.150GHz to 5.875GHz band, and the 6GHz band can be the 5.925GHz to 7.125GHz band. For example, to cover both the 5GHz and 6GHz Wi-Fi bands using the same antenna, electronic device 500 can adjust the antenna characteristics to cover a 1.975GHz bandwidth of the 5.150GHz to 7.125GHz band. For example, when scanning a communication channel, because electronic device 500 sends and receives data for scanning the channel without contacting external electronic devices (e.g., ...). Figure 1 The electronic device 102 transmits and receives relatively large amounts of data, so even though the antenna 511 has a relatively low gain, it can still scan the communication channel. For example, the electronic device 500 can adjust the characteristics of the antenna 511 to cover the entire frequency band of the communication channel while maintaining the minimum antenna gain required for scanning the communication channel. For example, the minimum antenna gain could be an antenna gain at a level that enables the external electronic device to transmit and receive signals and divide the frequency band used by the external electronic device. According to one embodiment, the electronic device 500 can adjust the characteristics of the antenna 511 to be broadband to cover the entire range used for scanning the communication channel, rather than having a relatively low gain, thereby effectively scanning the communication channel.

[0074] According to one embodiment, electronic device 500 can adjust the characteristics of antenna 511 to have low gain over a relatively wide frequency band. For example, electronic device 500 can adjust the characteristics of antenna 511 to have low gain over a wide bandwidth including the 5 GHz and 6 GHz frequency bands, as shown in B. According to another embodiment, electronic device 500 can adjust the characteristics of antenna 511 to be wide over multiple portions of the 5 GHz and 6 GHz frequency bands. For example, electronic device 500 can adjust the characteristics of antenna 511 to have low gain in the 5 GHz frequency band or the 6 GHz frequency band. As another example, electronic device 500 can adjust the characteristics of antenna 511 to have relatively low gain over a frequency band including Na, Nb, Nc, or... in the 5 GHz frequency band and / or N1, N2, N3, or... in the 6 GHz frequency band. For example, electronic device 500 can adjust the characteristics of antenna 511 to operate in at least some of the frequency bands including N1, N2, N3, or ..., or to operate in at least some of the frequency bands including Na, Nb, Nc, or ..., or to operate in a frequency band including multiple frequency bands including N1, N2, N3, ..., Na, Nb, Nc, or ... For example, electronic device 500 can adjust the gain of antenna 511 based on the adjusted frequency band characteristics of antenna 511. For example, electronic device 500 can reduce the gain of antenna 511, increase the bandwidth of antenna 511, and reduce power consumption without performing an operation to scan the entire frequency band.

[0075] According to one embodiment, electronic device 500 can use an antenna 511 tuned to broadband characteristics to determine a communication channel based on signals received from an external electronic device (e.g., a Wi-Fi base station or access point). For example, electronic device 500 can receive beacon signals or probe response signals from the external electronic device. For example, the signals received by electronic device 500 may include primary channel frequency information or channel bandwidth information. For example, the PHY header portion of the signals received by electronic device 500 may include primary channel frequency information, and the MAC header portion may include channel bandwidth information. For example, electronic device 500 can determine the communication channel based on information included in the received signals (e.g., primary channel frequency information and / or channel bandwidth information).

[0076] According to one embodiment, when a communication channel is determined, the electronic device 500 can adjust the characteristics of the antenna 511 to narrowband characteristics Na, Nb, Nc, N1, N2, or N3, and can perform communication with the external electronic device 500. For example, when a specific communication channel for communication with the external electronic device 500 is determined, the electronic device 500 can adjust the characteristics of the antenna 511 to have high gain in the frequency band corresponding to the determined communication channel. For example, when a communication channel is determined, the characteristics of the antenna 511 can be adjusted to have relatively high gain in the determined communication channel to effectively perform communication with the external electronic device 500.

[0077] refer to Figure 5B Electronic device 500 may include communication circuitry 510 (e.g., Figure 1 Communication module 190 or Figure 2 The communication circuit 210) and the processor 530 (e.g., Figure 1 Processor 120 or Figure 2 The processor 230). According to one embodiment, the communication circuit 510 may include an antenna 511, a Wi-Fi module (Wi-Fi baseband) 513, an RF module 515, a switch 517, and variable circuits 5171, 5173, and 5175 electrically connected to the antenna 511.

[0078] According to one embodiment, the Wi-Fi module 513 can be a module for performing Wi-Fi communication. It can provide the processor 530 with status information and / or operation-related information of the Wi-Fi module 513, receive control commands from the processor 530, and execute operations corresponding to the received control commands. For example, the Wi-Fi module 513 can generate the baseband signal required for Wi-Fi communication and transmit it to the RF module 515.

[0079] According to one embodiment, the RF module 515 can amplify and upconvert the frequency band signal generated by the Wi-Fi module 513 and transmit it to the antenna 511.

[0080] According to one embodiment, antenna 511 can radiate signals generated by RF module 515 or receive signals radiated by external electronic devices. According to one embodiment, antenna 511 may include at least one radiator and elements associated with antenna 511. According to one embodiment, the characteristics of antenna 511 (e.g., antenna gain and / or antenna operating frequency band) can be adjusted under the control of processor 530. According to one embodiment, antenna 511 may include at least one antenna comprising a conductor formed on a substrate (e.g., PCB) or a radiator composed of conductive patterns. According to another embodiment, antenna 511 may include at least one antenna that uses a portion of the metal (e.g., a metal frame) constituting the housing (not shown) of electronic device 500. According to another embodiment, antenna 511 may include at least one antenna utilizing at least some internal components of electronic device 500.

[0081] According to one embodiment, switch 517 can electrically connect or disconnect lumped elements (e.g., capacitors, inductors, and / or stubs) connected to antenna 511. For example, under the control of processor 530, switch 517 can electrically connect or disconnect at least one of a plurality of variable circuits 5171, 5173, and 5175 to or from antenna 511. According to one embodiment, the plurality of variable circuits 5171, 5173, and 5175 may include switches and / or lumped elements (e.g., capacitors, inductors, and / or stubs).

[0082] According to one embodiment, processor 530 can control the overall operation of electronic device 500. According to one embodiment, processor 530 can be connected to communication circuitry 510 (e.g., Wi-Fi module 513 and switch 517). For example, processor 530 can control Wi-Fi module 513 via a communication interface such as Fast Peripheral Component Interconnect (PCIe) or Secure Digital Input / Output (SDIO). For example, processor 530 can receive status information and operation-related information of Wi-Fi module 513 from Wi-Fi module 513 and can control Wi-Fi module 513 at least in part based on the received information. According to one embodiment, processor 530 can control switch 517 at least in part based on information received from Wi-Fi module 513. For example, processor 530 can use general purpose input / output (GPIO) signals to control switch 517. For example, processor 530 can control switch 517 to electrically connect at least one of variable circuits 5171, 5173, and 5175 to antenna 511. According to one embodiment, processor 530 can control switch 517 to connect at least one of variable circuits 5171, 5173, and 5175 to antenna 511, such that antenna 511 operates in a frequency band including a 5 GHz band, a 6 GHz band, or both 5 GHz and 6 GHz bands. For example, electronic device 500 can connect a first variable circuit 5171 to antenna 511, such that antenna 511 operates in the 5 GHz band; connect a second variable circuit 5173 to antenna 511, such that antenna 511 operates in the 6 GHz band; or connect a third variable circuit 5175 to antenna 511, such that antenna 511 operates in both the 5 GHz and 6 GHz bands. In this embodiment, when antenna 511 is connected to the first variable circuit 5171 or the second variable circuit 5173, it can have specified narrowband characteristics and can have relatively high antenna gain. For example, the first variable circuit 5171 can be configured to cause antenna 511 to operate in at least a portion of the 5 GHz band. For example, the second variable circuit 5173 can be configured to cause the antenna 511 to operate in at least a portion of the 6 GHz band. According to one embodiment, in a state where a communication channel has been determined, the processor 530 can control the switch 517 to connect either the first variable circuit 5171 or the second variable circuit 5173 to the antenna 511, such that the antenna 511 has antenna characteristics corresponding to the determined communication channel. For example, when the antenna 511 is connected to the third variable circuit 5175, it can have broadband characteristics including both the 5 GHz and 6 GHz bands, and can have a relatively low antenna gain.For example, when the electronic device 500 is scanning the communication channel, the processor 530 can control the switch 517 to connect the third variable circuit 5175 to the antenna 511, so that the antenna 511 has antenna characteristics including all 5GHz and 6GHz frequency bands.

[0083] According to various embodiments, the processor 530 can connect the third variable circuit 5175 to the antenna 511 and can adjust the antenna 511 to broadband characteristics in a communication channel scanning state for searching for at least one external electronic device 500 to perform Wi-Fi communication, a communication channel scanning state for indoor positioning of the electronic device 500, or a communication channel scanning state for roaming setup. For example, the electronic device 500 can scan communication channels to search for surrounding access points (APs) in order to access the device when it is not connected to an AP for Wi-Fi communication. As another example, when the electronic device 500 is connected to an AP, it can scan communication channels for roaming or handover when communication quality deteriorates and / or when the electronic device 500 wants to change its currently connected AP to another AP. As another example, the electronic device 500 can obtain SSID information from surrounding APs and can scan communication channels to identify its current location.

[0084] Figures 6A to 6D Examples of variable circuits included in an electronic device according to various embodiments are illustrated.

[0085] According to one embodiment, an electronic device (e.g., Figure 1 Electronic devices 101 or Figure 2 The communication circuit of the electronic device 200 (e.g., Figure 1 Communication module 190 or Figure 2 The communication circuit 210 may include a means for adjusting the antenna 601 (e.g., Figure 2 A variable circuit 630 that determines the characteristics of the antenna 211. According to one embodiment, the variable circuit 630 may include at least one switch 631 and lumped elements a, b, c, and d. Figures 6A to 6D The diagram illustrates a planar inverted F-shaped antenna, but the type of antenna is not limited to this. According to various embodiments, electronic devices may include various types of antennas.

[0086] According to one embodiment, at least one switch 631 may be electrically connected to at least a portion of the antenna 601. For example, Figure 6A The diagram illustrates the circuit structure in which switch 631 and antenna feed section (F) 620 are connected in parallel. Figure 6B The diagram illustrates a circuit structure in which switch 631 is connected in parallel with antenna grounding section (G) 610. For example, Figure 6CThe diagram illustrates the circuit structure in which switch 631 is connected in series with antenna feed section (F) 620, and Figure 6D The diagram illustrates the circuit structure in which switch 631 is connected in series with antenna grounding part (G) 610.

[0087] According to one embodiment, at least one lumped element a, b, c, or d may be electrically connected to switch 631. According to various embodiments, Figures 6A to 6D The lumped elements a, b, c, and d shown are schematically illustrated as examples, but are not limited thereto. At least one lumped element a, b, c, or d can be electrically connected in series or parallel with switch 631 in various forms. According to various embodiments, Figures 6A to 6D Each of a, b, c, and d shown can be a circuit comprising one or more lumped elements. For example, each of a, b, c, and d can include an element or circuit corresponding to a specific antenna band characteristic (or antenna gain). For example, each of a, b, c, and d can be implemented as a lumped element, such as an inductor or capacitor, or a microstrip line, an open-circuit stub, and / or (multiple) short-circuit stub circuits. The four lumped elements a, b, c, and d in Figures 6A to 6D The diagram is shown in the figure. However, according to various embodiments, the number of lumped elements can change the antenna band characteristics (or antenna gain) in a specified frequency band, and the number or form can be implemented differently. According to one embodiment, the electronic device can control switch 631 to select at least one of the desired lumped elements a, b, c, or d. For example, the electronic device can adjust the characteristics of antenna 601 to narrowband or wideband characteristics by controlling switch 631 to select at least one of a, b, c, or d. For example, the electronic device can control switch 631 such that multiple lumped elements are connected to antenna 601 to have a low Q value, thereby adjusting antenna 601 to wideband characteristics, or it can control switch 631 such that a single lumped element is connected to antenna 601 to have a high Q value, thereby adjusting antenna 601 to narrowband characteristics. For example, when connected to antenna 601, each of a, b, c, and d can be configured such that antenna 601 has different band characteristics and / or different antenna gains. For example, a, b, and c can be configured such that when connected to antenna 601, antenna 601 has relatively narrowband characteristics and high antenna gain, and d can be configured such that when connected to antenna 601, antenna 601 has relatively wideband characteristics and low antenna gain. For example, the electronic device can control the switch based on the communication state to selectively electrically connect appropriate lumped elements among the plurality of lumped elements a, b, c, and d to antenna 601.

[0088] As another example, in order to adjust the Q value, electronic devices can have different settings for the thickness and / or length of microstrip lines, open stubs, and / or short stubs.

[0089] Figure 7 This is a block diagram of an electronic device according to one embodiment.

[0090] According to one embodiment, electronic device 700 (e.g., Figure 1 Electronic devices 101 Figure 2 Electronic devices 200 or Figure 5B The electronic device 500 may include a Wi-Fi module 710, a UWB module 720, a switching circuit 730, a first antenna 741, a second antenna 743, a third antenna 745, and a processor 750 (e.g., Figure 1 Processor 120 Figure 2 The processor 230, or Figure 5B The processor 530).

[0091] According to one embodiment, the Wi-Fi module 710 and the UWB module 720 can be implemented as a single module (or chipset) (e.g., Figure 1 Communication module 190 Figure 2 Communication circuit 210 or Figure 5B The communication circuit 710 can be implemented as an independent module (or chipset). According to one embodiment, the Wi-Fi module 710 may include a module 711 for supporting Wi-Fi in the 2.4 GHz band and a module 713 for supporting Wi-Fi in the 5 GHz and 6 GHz bands. For example, modules 711 and 713 can be configured as independent modules and can be logically divided and configured within a single Wi-Fi module 710. According to one embodiment, the Wi-Fi module 710 and the UWB module 720 can send and receive information (e.g., communication status information and / or operation status information) to each other via the internal communication interface of the electronic device 700 or via the processor 750.

[0092] According to one embodiment, a first antenna 741 can be configured for 2.4 GHz band Wi-Fi communication, a second antenna 743 can be configured for 5 GHz / 6 GHz band Wi-Fi communication or UWB communication, and a third antenna 745 can be configured for UWB communication. For example, the frequency band supported in UWB communication can be from 5 GHz to 8 GHz, and at least a portion of the frequency band supported in UWB communication can overlap with the frequency band supported in 5 GHz / 6 GHz band Wi-Fi communication. For example, under the control of a processor 750, the second antenna 743 can be selectively used for Wi-Fi communication or UWB communication in a portion of the frequency band commonly supported by both Wi-Fi and UWB communication.

[0093] According to one embodiment, processor 750 may include an application processor (e.g., Figure 1The main processor 121) and / or the communication processor (e.g., Figure 1 (Auxiliary processor 123). According to one embodiment, processor 750 may be electrically connected and / or operatively connected to Wi-Fi module 710 and UWB module 720. For example, processor 750 may control Wi-Fi module 710 and / or UWB module 720 via a communication interface (e.g., Fast Peripheral Component Interconnect (PCIe) or Serial Peripheral Interface (SPI)). For example, processor 750 may control switching circuit 730 via control signals (e.g., General Purpose I / O (GPIO) signals). For example, electronic device 700 may control switching circuit 730 to selectively connect second antenna 743 to Wi-Fi module 710 or UWB module 720.

[0094] According to one embodiment, the processor 750 can receive information associated with the communication state from the Wi-Fi module 710 and / or the UWB module 720. For example, the processor 750 can receive communication-related information and / or information about the operating state from each of the Wi-Fi module 710 and / or the UWB module 720. For example, the processor 750 can receive UWB communication-related information (e.g., UWB ranging time period-related information) from the UWB module 720.

[0095] According to one embodiment, when receiving UWB communication-related information from UWB module 720, during Wi-Fi communication via Wi-Fi module 710, processor 750 can adjust the characteristics of second antenna 743 to correspond to UWB communication, and can electrically connect second antenna 743 to UWB module 720. For example, processor 750 can use second antenna 743 to perform UWB communication in the 5GHz to 6GHz band, and can use third antenna 745 to perform UWB communication in the 7GHz to 8GHz band. For example, processor 750 can process UWB communication with a higher priority than Wi-Fi communication. According to one embodiment, when UWB communication ends, processor 750 can adjust the characteristics of second antenna 743 to correspond to Wi-Fi communication, and can electrically connect second antenna 743 to Wi-Fi module 710. For example, processor 750 can use first antenna 741 to perform 2.4GHz band Wi-Fi communication, and can use second antenna 743 to perform 5GHz to 6GHz band Wi-Fi communication.

[0096] According to various embodiments, Figure 7 The illustration shows a first antenna 741, a second antenna 743, and a third antenna 745, but the number of antennas included in the electronic device 700 is not limited to this. The electronic device 700 can be implemented in various forms, including by a processor 750 and a switching circuit 730 (e.g., Figure 5B 517 or Figures 6A to 6D At least one antenna controlled by switch 631 (e.g., Figure 2 Antenna 211, Figure 5B Antenna 511, Figures 6A to 6D Antenna 601). According to one embodiment, electronic device 700 may include variable circuitry (e.g., antenna 601). Figure 5B Variable circuits 5171, 5173 and 5175 or Figures 6A to 6D The variable circuit 630), which is connected via the switching circuit 730 and / or lumped elements (e.g., Figures 6A to 6D The lumped elements a, b, c, and d) are connected to at least one antenna 741, 743, or 745. For example, electronic device 700 may include an antenna that can operate across the entire Wi-Fi communication supported frequency band (e.g., the 2.4 GHz band, the 5 GHz band, and the 6 GHz band) and the UWB communication supported frequency band. For example, electronic device 700 may include an antenna used independently of each of Wi-Fi module 710 and UWB module 720, without an antenna shared by Wi-Fi module 710 and UWB module 720. In this case, to reduce the impact of interference that may occur in the same or adjacent frequency bands, processor 750 may, based on UWB communication scheduling, at least temporarily suspend signal transmission according to Wi-Fi communication.

[0097] An electronic device according to one embodiment (e.g., Figure 1 Electronic devices 101 Figure 2 200 electronic devices Figure 5B Electronic devices 500 or Figure 7 The electronic device 700 may include: a communication circuit (e.g., Figure 1 Communication module 190 Figure 2 Communication circuit 210, Figure 5B The communication circuit 510, or Figure 7 The Wi-Fi module 710 and UWB module 720), the communication circuit includes at least one antenna (e.g., Figure 2 Antenna 211, Figure 5B Antenna 511, Figures 6A to 6D Antenna 601 or Figure 7 Antennas 741, 743, and 745); memory (e.g., Figure 1 memory 130 or Figure 2 The memory 220); and a processor operably connected to the communication circuitry and the memory (e.g., Figure 1 Processor 120 Figure 2 Processor 230, Figure 5B processor 530 or Figure 7 The processor 750).

[0098] According to one embodiment, the memory may include instructions that, when executed, cause the processor to identify the communication state of the communication circuit; when the identified communication state is that a Wi-Fi communication channel is being scanned, adjust the antenna characteristics to a wideband characteristic including a first Wi-Fi band and a second Wi-Fi band through the communication circuit to scan the Wi-Fi communication channel; and when the identified communication state is that the Wi-Fi communication channel to be communicated is determined, adjust the antenna characteristics to a narrowband characteristic corresponding to the determined communication channel to perform Wi-Fi communication.

[0099] According to one embodiment, the first Wi-Fi band may include a 5GHz Wi-Fi band, and the second Wi-Fi band may include a 6GHz Wi-Fi band.

[0100] According to one embodiment, the communication circuit may include at least one or more variable circuits configured to adjust the characteristics of the antenna (e.g., Figure 5B The variable circuits 5171, 5173, and 5175, Figures 6A to 6D The variable circuit 630, or Figure 7 (Switching circuit 730).

[0101] According to one embodiment, the variable circuit may include at least one switch (e.g., Figure 5B Switch 517 Figures 6A to 6D Switch 631, or Figure 7 The switching circuit 730) and lumped components (e.g., Figures 6A to 6D (The lumped components a, b, c, and d). According to one embodiment, the instructions can enable the processor to control at least one switch to adjust the characteristics of the antenna.

[0102] According to one embodiment, the state in which the communication channel is scanned may include at least one of the following: a communication channel scanning state for searching for at least one external electronic device to perform Wi-Fi communication, a communication channel scanning state for indoor positioning of the electronic device, or a communication channel scanning state for roaming settings.

For example, the electronic device can identify the connection state of the communication channel. For example, the electronic device can identify whether the identified communication state is a state where the Wi-Fi communication channel is scanned or a state where the Wi-Fi communication channel is determined. For example, the electronic device can use the communication circuit (e.g., Figure 1 Communication module 190 or Figure 2The communication circuit 210 receives signals from external electronic devices (e.g., access points (APs)) and can identify the connection status of the communication channel based on the received signals. According to one embodiment, the communication channel scanning state can include at least one of the following: a communication channel scanning state for searching for at least one external electronic device (e.g., AP) to perform Wi-Fi communication; a channel scanning state for changing the communication channel of a communication-connected external electronic device; a communication channel scanning state for indoor positioning of the electronic device; or a communication channel scanning state for roaming settings of the electronic device. For example, the electronic device can receive signal strength and / or location information of external electronic devices (e.g., APs) present around it based on a specified time or specified conditions for indoor positioning. According to one embodiment, the specified conditions can include changes in GPS signal strength, a specified location, a specified time period, and / or the values ​​of at least one sensor included in the electronic device. For example, the electronic device can include operations similar to scanning external electronic devices to substantially determine the Wi-Fi communication channel for indoor positioning. For example, the electronic device can receive information about surrounding external electronic devices for roaming settings and can perform operations similar to scanning external electronic devices to substantially determine the Wi-Fi communication channel. According to one embodiment, when communication conditions deteriorate (e.g., when communication quality drops to a specified level or lower) while the electronic device is performing Wi-Fi communication with a specific external electronic device (e.g., an access point), the electronic device can switch to a communication channel scanning state to search for new external electronic devices (e.g., new access points).

[0114] According to one embodiment, in operation 820, when the identified communication state is that the Wi-Fi communication channel is being scanned, the electronic device can (e.g., ...)

In an embodiment, the electronic device can adjust the characteristics of the antenna so that the antenna operates in a frequency band including a first Wi-Fi band and a second Wi-Fi band. For example, the first Wi-Fi band may include a 5 GHz Wi-Fi band, and the second Wi-Fi band may include a 6 GHz Wi-Fi band. According to one embodiment, the electronic device can use a variable circuit (e.g., [missing information]) connected to the antenna. Figure 5BThe electronic device uses variable circuits 5171, 5173, or 5175 to adjust the characteristics of the antenna. For example, the variable circuit may include at least one switch and lumped elements.

As another example, the electronic device may adjust the antenna characteristics (e.g., the antenna gain and / or the antenna operating frequency) such that the antenna's operating frequency range includes both the first and second Wi-Fi bands. According to one embodiment, the electronic device can use an antenna with broadband characteristics to scan a communication channel across the entire range including the 5 GHz Wi-Fi band and the 6 GHz Wi-Fi band. For example, the electronic device may set the antenna gain to the level required only for scanning the communication channel, and may increase the antenna's operating frequency band to scan the communication channel in a broadband manner, thereby reducing the power and time consumed in scanning the communication channel. According to one embodiment, the antenna gain used for scanning the communication channel may be lower than the antenna gain used to determine the state of the communication channel.

[0115] According to one embodiment, the electronic device can provide the results of scanning communication channels. For example, the electronic device can determine a specific communication channel (e.g., a communication channel corresponding to a specific Wi-Fi AP) among the scanned communication channels based on user input and / or bandwidth. For example, when performing roaming and handover, the electronic device can determine the communication channel and / or communication bandwidth based on a predetermined algorithm. For example, the electronic device can pass the scanning results (e.g., a list of all scanned Wi-Fi APs) to the frame layer. For example, the frame layer can determine the AP with the highest roaming score based on an algorithm for calculating roaming scores. For example, the electronic device can determine the communication channel corresponding to the AP with the highest roaming score. For example, the electronic device can determine the communication channel based on AP channel information and bandwidth information included in signals received during scanning of communication channels (e.g., beacon signals or probe response signals).

[0116] According to one embodiment, in operation 830, when the identified communication state is that a Wi-Fi communication channel is determined, the electronic device can adjust the antenna characteristics to narrowband characteristics to perform Wi-Fi communication. For example, when a communication channel is determined, the electronic device can perform Wi-Fi communication with a specific external electronic device (e.g., an access point) through the determined communication channel. For example, the electronic device can adjust the antenna characteristics so that the antenna operates in the frequency band corresponding to the determined communication channel. For example, the electronic device can adjust the antenna characteristics to a narrowband of a specified frequency band to facilitate smooth communication in the determined communication channel and can increase the antenna gain in the specified frequency band. For example, the electronic device can use an antenna with narrowband characteristics to perform Wi-Fi communication with a specified external electronic device on the determined communication channel. According to one embodiment, when a communication channel to a specific external electronic device (e.g., an access point) is determined, the electronic device can perform communication with the corresponding external electronic device through the antenna.

Figure 8 and Figure 9 Operations that are the same as or similar to those described in the previous section will be omitted or briefly described in the description.

[0126] According to one embodiment, in operation 1010, the electronic device (e.g., Figure 1 Electronic devices 101 Figure 2 200 electronic devices Figure 5B Electronic devices 500 or Figure 7 The electronic device 700 can identify the network connection status. For example, the electronic device can identify the currently used communication scheme (e.g., Wi-Fi) and the communication status (e.g., communication channel or communication quality).

[0127] According to one embodiment, in operation 1020, the electronic device can determine the communication scheme to be used.

For example, the electronic device can determine whether it is necessary to scan for at least one external electronic device to perform Wi-Fi communication, whether it is necessary to scan for a communication channel for indoor positioning, or whether it is necessary to scan for a communication channel for roaming setup. According to one embodiment, when it is necessary to scan a communication channel, the electronic device can perform operation 1040, and when it is not necessary to scan a communication channel (e.g., when the communication channel has been determined (fixed)), it can perform operation 1060.
