[0033] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0035] Furthermore, in the embodiments of this application, directional terms such as "up," "down," "left," "right," "horizontal," and "vertical" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0036] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection / linking" should be interpreted broadly, and may refer to a mechanical connection or a physical connection. That is, A and B being connected or linked may mean that there are fastening components (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and are difficult to separate.

[0037] Communication connection: This can refer to the transmission of electrical signals, such as wireless communication connections and / or wired communication connections. Wireless communication connections do not require a physical medium and are not considered connections that limit the structure of a product.

[0038] Coupling can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as a direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection," which can be understood as physical contact and electrical conduction between components; it can also be understood as the form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Indirect coupling" can be understood as electrical conduction between two conductors through a gap / non-contact method. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gaps between two conductive components.

[0039] Connection: The process of making two or more components conduct or connect through the above-mentioned "electrical connection" or "indirect coupling" to transmit signals / energy can be called connection.

[0040] A radiator, or antenna stub, is a device in an antenna used to receive / transmit electromagnetic wave radiation. In some cases, the term "antenna" is narrowly defined as a radiator, which converts guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via a feed line, where it is converted into electromagnetic wave energy of a specific polarization and radiated in the desired direction. The receiving radiator converts electromagnetic wave energy of a specific polarization from a specific direction in space back into modulated high-frequency current energy, which is then transmitted to the receiver input via a feed line.

[0041] Radiators (or antenna stubs) may include conductors with specific shapes and sizes, such as wires or sheets, and this application does not limit the specific shape. In one embodiment, a wire radiator may be simply referred to as a wire antenna. In one embodiment, a wire radiator may be implemented by a conductive frame, and may also be referred to as a frame antenna. In one embodiment, a wire radiator may be implemented by a support conductor, and may also be referred to as a support antenna. In one embodiment, the wire diameter (e.g., including thickness and width) of the wire radiator, or the radiator of the wire antenna, is much smaller than the wavelength (e.g., the wavelength of the medium) (e.g., less than 1 / 16 of the wavelength), and the length may be comparable to the wavelength (e.g., the wavelength of the medium) (e.g., a length of approximately 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of wire antennas include dipole antennas, half-wave dipole antennas, monopole antennas, loop antennas, and inverted F antennas (also known as IFAs). For example, in a dipole antenna, each dipole antenna typically includes two radiating stubs, each fed from the feed end of the radiating stub by a feed section. For example, an inverted-F antenna (IFA) can be considered as a monopole antenna with an added ground path. An IFA antenna has one feed point and one ground point, and is called an inverted-F antenna because its side view is inverted-F shaped. In one embodiment, the sheet radiator may include a microstrip antenna or a patch antenna, such as a planar inverted-F antenna (also known as a PIFA). In one embodiment, the sheet radiator may be implemented using a planar conductor (e.g., a conductive sheet or conductive coating). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet. In one embodiment, the sheet radiator may include a conductive coating, such as silver paste. The shape of the sheet radiator includes circular, rectangular, and annular shapes, and this application does not limit the specific shape. The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator, and a ground plane, wherein the dielectric substrate is disposed between the radiator and the ground plane.

[0042] Radiators (or antenna stubs) may also include slots or gaps formed on a conductor, for example, closed or semi-closed slots or gaps formed on a grounded conductor surface. In one embodiment, a slotted or slit radiator may be simply referred to as a slot antenna or a gap antenna. In one embodiment, the radial dimension (e.g., including width) of the slot or gap of the slot antenna / gap antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), while the length dimension may be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., a length of approximately 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, a radiator with a closed slot or gap may be simply referred to as a closed slot antenna. In one embodiment, a radiator with a semi-closed slot or gap (e.g., an opening added to a closed slot or gap) may be simply referred to as an open slot antenna. In some embodiments, the gap shape is elongated. In some embodiments, the length of the gap is approximately half a wavelength (e.g., the dielectric wavelength). In some embodiments, the length of the gap is approximately an integer multiple of a wavelength (e.g., one dielectric wavelength). In some embodiments, the slot can be fed by transmission lines connected across one or both sides, thereby exciting a radio frequency electromagnetic field on the slot and radiating electromagnetic waves into space. In one embodiment, the radiator of the slot antenna or gap antenna can be implemented by a conductive frame grounded at both ends, also known as a frame antenna; in this embodiment, the slot antenna or gap antenna can be viewed as including a linear radiator, the linear radiator being spaced apart from the ground and grounded at both ends, thereby forming a closed or semi-closed slot or gap. In one embodiment, the radiator of the slot antenna or gap antenna can be implemented by a support conductor grounded at both ends, also known as a support antenna.

[0043] Communication / Operating Frequency Band: Regardless of the type of antenna, it always operates within a certain frequency range (bandwidth). For example, an antenna supporting the B40 band operates within the frequency range of 2300MHz to 2400MHz, or in other words, its operating frequency band includes the B40 band. The frequency range that meets the specifications can be considered the antenna's operating frequency band. The width of the operating frequency band is called the operating bandwidth. The operating bandwidth of an omnidirectional antenna may reach 3-5% of the center frequency. The operating bandwidth of a directional antenna may reach 5-10% of the center frequency. Bandwidth can be considered as a frequency range on both sides of the center frequency (e.g., the resonant frequency of a dipole), where the antenna characteristics are within the acceptable range of the center frequency.

[0044] The resonant frequency band and the operating frequency band can be the same or can partially overlap. In one embodiment, one or more resonant frequency bands of the antenna can cover one or more operating frequency bands of the antenna.

[0045] End / Point: The term "end / point" in the context of the antenna radiator's first end / second end / feed end / ground end / feed point / ground point / connection point should not be narrowly interpreted as necessarily an endpoint or end physically disconnected from other radiators. It can also be considered a point or segment on a continuous radiator. In one embodiment, "end / point" can include a connection / coupling region on the antenna radiator that couples to other conductive structures. For example, a feed end / feed point can be a coupling region on the antenna radiator that couples to a feed structure or feed circuit (e.g., a region facing a part of the feed circuit). Similarly, a ground end / ground point can be a connection / coupling region on the antenna radiator that couples to a ground structure or ground circuit.

[0046] The same operating frequency band mentioned in the embodiments of this application (also known as, same frequency) can be understood as either of the following two situations:

[0047] 1) The operating frequency bands of the first antenna and the second antenna include the same communication frequency band. In one embodiment, both the first antenna and the second antenna serve as sub-units in a MIMO antenna system. For example, the operating frequency bands of both the first antenna and the second antenna include sub-future communication network frequency bands in 5G.

[0048] 2) The operating frequency bands of the first antenna and the second antenna partially overlap. For example, the operating frequency band of the first antenna includes B35 (1.85-1.91GHz) in LTE, while the operating frequency band of the second antenna includes B39 (1.88-1.92GHz) in LTE.

[0049] Isolation: Isolation refers to the ratio of the signal received by one antenna through another to the signal received by the transmitting antenna. It's a physical quantity used to measure the degree of mutual coupling between antennas. Assuming two antennas form a two-port network, the isolation between them is represented by their S21 and S12 parameters. Antenna isolation can be expressed using S21 and S12 parameters, which are also types of S-parameters. S21 and S12 parameters are usually negative. Smaller S21 and S12 parameters indicate greater isolation and less mutual coupling between antennas; larger S21 and S12 parameters indicate less isolation and greater mutual coupling. Antenna isolation depends on factors such as the antenna radiation pattern, the spatial distance between antennas, and antenna gain.

[0050] Ground / Plug: This can broadly refer to at least a portion of any grounding layer, ground plane, or grounding metal layer within an electronic device (such as a mobile phone), or at least a portion of any combination of the aforementioned grounding layers, ground planes, or grounding components. "Ground / Plug" can be used for grounding components within an electronic device. In one embodiment, "Ground / Plug" may include any one or more of the following: a grounding layer of a circuit board of an electronic device, a ground plane formed by the frame of the electronic device, a grounding metal layer formed by a thin metal film beneath the screen, a conductive grounding layer of a battery, and conductive or metallic components electrically connected to the aforementioned grounding layer / ground plane / metal layer. In one embodiment, the circuit board may be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12-14-layer board having 8, 10, 12, 13, or 14 layers of conductive material, or components separated and electrically insulated by dielectric or insulating layers such as glass fiber or polymers. In one embodiment, the circuit board includes a dielectric substrate, a grounding layer, and a trace layer, with the trace layer and grounding layer electrically connected via vias. In one embodiment, components such as displays, touchscreens, input buttons, transmitters, processors, memory, batteries, charging circuits, and system-on-chip (SoC) architectures can be mounted on or connected to a circuit board; or electrically connected to trace layers and / or ground layers in the circuit board. For example, a radio frequency source is disposed on a trace layer.

[0051] Any of the aforementioned grounding layers, ground planes, or grounding metal layers are made of conductive materials. In one embodiment, the conductive material may be any of the following: copper, aluminum, stainless steel, brass and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil on an insulating substrate and tin-plated copper, graphite-impregnated cloth, graphite-coated substrates, copper-plated substrates, brass-plated substrates, and aluminum-plated substrates. Those skilled in the art will understand that grounding layers / ground planes / grounding metal layers may also be made of other conductive materials.

[0052] Grounding: refers to coupling with the aforementioned ground / floor in any way. In one embodiment, grounding can be achieved through physical grounding, such as through a structural component of the mid-frame to achieve a physical ground at a specific location on the frame (or, physical ground). In another embodiment, grounding can be achieved through device grounding, such as through devices like capacitors / inductors / resistors connected in series or parallel (or, device ground).

[0053] A matching circuit is a circuit associated with adjusting the radiation characteristics of an antenna. In one embodiment, the matching circuit is coupled between the feed circuit and the corresponding radiator. Typically, the matching circuit is coupled between the test mount and the radiator. In one embodiment, the matching circuit has impedance matching and / or frequency tuning functions. It is generally considered part of the antenna.

[0054] A tuning circuit is a circuit associated with adjusting the resonant frequency of an antenna. In one embodiment, the tuning circuit is coupled between the radiator and the ground. In another embodiment, the tuning circuit is coupled between the feed circuit and the radiator. In yet another embodiment, the tuning circuit functions as impedance matching and / or frequency tuning. Typically, it is considered part of the antenna.

[0055] In one embodiment, the matching circuit / tuning circuit may include switches and / or electronic components / devices, where the switches are electronic components / devices for switching the coupling connection of the radiator. The switches in the matching circuit / tuning circuit may also be referred to as antenna switches. In one embodiment, the matching circuit / tuning circuit may include a filter circuit.

[0056] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings.

[0057] This application provides a wearable electronic device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as smart glasses, smartwatches, VR / AR headsets, etc. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices; they achieve powerful functions through software support, data interaction, and cloud interaction.

[0058] In this embodiment of the application, only headphones are used as an example of wearable electronic devices for illustration.

[0059] Wearable electronic devices include a feed radiator, which, when used as an antenna, enables wireless communication between the wearable electronic device and a peer device. The peer device can include handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem. It can also include user units, cellular phones, smartphones, wireless data cards, personal digital assistant (PDA) computers, tablet computers, wireless modems, handsets, laptop computers, etc.

[0060] Wearable electronic devices include a housing. In some examples, the housing can be made of metal, plastic, or ceramic. Specifically, metal materials can be, for example, aluminum alloy or stainless steel, while plastic materials can be, for example, ABS resin or polycarbonate (PC).

[0061] Furthermore, the feed radiator can be mounted on the housing. For example, the feed radiator can be arranged on the inner wall of the housing using laser direct structuring (LDS) and flexible printed circuit (FPC) technology. When the housing material is metal, the housing will also serve as part of the antenna.

[0062] As shown in Figure 1, the wearable electronic device also includes a communication component, which can be located within a predetermined area enclosed by the housing. The communication component may include a communication chip 40. The communication chip 40 can be coupled to a feed radiator via a bandpass filter and a radio frequency front end, enabling the communication chip 40 to transmit or receive radio frequency signals through the feed radiator.

[0063] In some embodiments, the number of feed radiators can be two. For example, the feed radiators may include a first feed radiator 11 and a second feed radiator 12, and the communication chip 40 can be switched to couple with either the first feed radiator 11 or the second feed radiator 12 via an SPDT switch. Both the first feed radiator 11 and the second feed radiator 12 can be used to receive or transmit radio frequency signals in the first frequency band.

[0064] In some embodiments, the first frequency band may include 2.4 GHz, which may cover 2402 MHz to 2480 MHz.

[0065] In practical applications, the signal strengths of the first feed radiator 11 and the second feed radiator 12 can be compared. When the signal strength of the first feed radiator 11 is greater than that of the second feed radiator 12, the communication chip 40 can couple with the first feed radiator 11, and the communication chip 40 can receive or transmit radio frequency signals of the first frequency band through the first feed radiator 11. Conversely, the communication chip 40 can couple with the second feed radiator 12, and the communication chip 40 can receive or transmit radio frequency signals of the first frequency band through the second feed radiator 12.

[0066] However, in places with high traffic (such as airports and train stations), the radio frequency signal of the first frequency band is subject to strong interference, the benefit of the first feed radiator 11 or the second feed radiator 12 when used as an antenna is low, and there are also stuttering issues when wearable electronic devices communicate with peer devices (e.g., call stuttering or music playback stuttering).

[0067] In view of this, as shown in FIG2, in this embodiment of the application, the communication chip 40 can be switched to couple with either the first feed radiator 11 or the second feed radiator 12. The communication chip 40 is used to transmit or receive radio frequency signals of the first frequency band through the first feed radiator 11 at a first moment; transmit or receive radio frequency signals of the first frequency band through the second feed radiator 12 at a second moment; and transmit or receive radio frequency signals of the second frequency band through the first feed radiator 11 at a third moment.

[0068] The second frequency band may include, for example, 5GHz, which can include 5.1GHz and 5.8GHz. The 5.1GHz band can cover 5150MHz to 5350MHz, and the 5.8GHz band can cover 5725MHz to 5850MHz. In some other examples, the second frequency band may also cover 5.925GHz to 7.125GHz.

[0069] In some embodiments, the first feed radiator 11 can be a dual-band antenna that transmits and receives radio frequency signals in the first frequency band and the second frequency band, and the second feed radiator 12 can be a single-band antenna that transmits and receives radio frequency signals in the first frequency band.

[0070] In some embodiments, the radio frequency signal of the first frequency band and the radio frequency signal of the second frequency band include radio frequency signals of different frequency bands within the same short-range communication technology. The short-range wireless communication technology includes Wi-Fi, Bluetooth, and other communication technologies. It should be understood that the embodiments of this application can also be applied to future technologies of short-range wireless communication.

[0071] For example, the radio frequency signal of the first frequency band and the radio frequency signal of the second frequency band can both be radio frequency signals of the Bluetooth communication frequency band (that is, the first frequency band and the second frequency band are used to support Bluetooth communication), one of which can be the Bluetooth 2.4GHz radio frequency signal and the other can be the Bluetooth 5GHz frequency band radio frequency signal; as another example, the radio frequency signal of the first frequency band and the radio frequency signal of the second frequency band can both be radio frequency signals of the Wi-Fi communication frequency band (that is, the first frequency band and the second frequency band are used to support Wi-Fi communication), one of which can be the Wi-Fi 2.4GHz radio frequency signal and the other can be the Wi-Fi 5GHz frequency band radio frequency signal.

[0072] By using the above settings, it is possible to preferentially use radio frequency signals from different frequency bands within the same short-range communication technology for communication, which is beneficial for improving communication performance.

[0073] Alternatively, in some other embodiments, the radio frequency signal of the first frequency band and the radio frequency signal of the second frequency band include radio frequency signals of different frequency bands under the same communication standard. The communication standard includes 3G / 4G / 5G and other communication standards. It should be understood that the embodiments of this application can also be applied to future communication standards of cellular communication.

[0074] For example, the radio frequency signals of the first frequency band and the radio frequency signals of the second frequency band can both be 4G communication (fourth generation mobile communication technology 4G) (that is, used to support 4G cellular communication), and they are two different frequency bands in the 4G cellular frequency band.

[0075] By using the above settings, it is possible to preferentially use radio frequency signals of different frequency bands under the same communication standard for communication, which is beneficial to improving communication performance.

[0076] In some embodiments, the communication chip 40 is used to communicate with the peer device via a first frequency band radio frequency signal at a first time and a second time. The communication chip 40 is also used to communicate with the peer device via a second frequency band radio frequency signal at a third time.

[0077] The first moment and the second moment can be when the interference intensity of the radio frequency signal in the first frequency band is less than the interference intensity of the radio frequency signal in the second frequency band. At this time, the communication chip 40 transmits or receives the radio frequency signal in the first frequency band through the first feed radiator 11 or the second feed radiator 12.

[0078] Conversely, the third moment can be when the interference intensity of the second frequency band radio frequency signal is less than the interference intensity of the first frequency band radio frequency signal. At this time, the communication chip 40 transmits or receives the second frequency band radio frequency signal through the first feed radiator 11.

[0079] Specifically, when the communication chip 40 communicates with the peer device in the second frequency band, it can use frequency hopping technology. For example, when the wearable electronic device communicates with the peer device using Bluetooth technology, the frequency hopping technology used can be adaptive frequency hopping (AFH). For example, the communication chip 40 can use 5.1GHz or 5.8GHz within the 5GHz band.

[0080] With the above settings, the communication chip 40 can switch to communicate with the peer device in the first frequency band or the second frequency band, which is beneficial to improving the communication performance between wearable electronic devices and peer devices.

[0081] In summary, the communication chip 40 can switch between communicating in the first frequency band or the second frequency band. Furthermore, when communicating in the first frequency band, the communication chip 40 can also switch between communicating through the first feed radiator 11 and the second feed radiator 12. This is beneficial for expanding the communication frequency band of the communication chip 40 and for improving the communication performance between wearable electronic devices and peer devices in places with high traffic.

[0082] In some embodiments, the communication chip 40 is further configured to transmit or receive a second frequency band radio frequency signal via the second feed radiator 12 at a fourth time. Accordingly, the communication chip 40 is also configured to communicate with the peer device via the second frequency band radio frequency signal at the fourth time.

[0083] The second feed radiator 12 can be a dual-band antenna that transmits and receives radio frequency signals in the first and second frequency bands.

[0084] With the above configuration, when the communication chip 40 communicates in the second frequency band, it can switch between communicating with the peer device via the first feed radiator 11 or the second feed radiator 12. This is beneficial for further improving the communication performance between wearable electronic devices and peer devices in crowded places.

[0085] In some examples, as shown in Figure 2, the communication component may include a switching circuit 20, with a first port A of the switching circuit coupled to a first radio frequency port 41 of the communication chip, a second port B of the switching circuit coupled to a second radio frequency port 42 of the communication chip, a third port C of the switching circuit coupled to a first feed radiator 11, and a fourth port D of the switching circuit coupled to a second feed radiator 12.

[0086] In some embodiments, the first port A of the switching circuit can be switched to couple with either the third port C or the fourth port D of the switching circuit. In some embodiments, the second port B of the switching circuit can be switched to couple with either the third port C or the fourth port D of the switching circuit. For example, the switching circuit 20 may include a DPDT switch.

[0087] Through the above configuration, the first radio frequency port 41 of the communication chip can be switched to couple with either the first feed radiator 11 or the second feed radiator 12, and the second radio frequency port 42 of the communication chip can be switched to couple with either the first feed radiator 11 or the second feed radiator 12. Specifically, the first radio frequency port 41 of the communication chip can be used to transmit or receive radio frequency signals in a first frequency band, and the second radio frequency port 42 of the communication chip can be used to transmit or receive radio frequency signals in a second frequency band.

[0088] Furthermore, referring to Figure 3, the communication component may also include a first filtering unit 51 and a second filtering unit 52. The first port A of the switching circuit can be coupled to the first radio frequency port 41 of the communication chip through the first filtering unit 51, and the second port B of the switching circuit can be coupled to the second radio frequency port 42 of the communication chip through the second filtering unit 52.

[0089] For example, the first filtering unit 51 may include a bandpass filter, which can be used to filter radio frequency signals in the first frequency band; the second filtering unit 52 may include a bandpass filter, which can be used to filter radio frequency signals in the second frequency band.

[0090] At the first moment, the first port A of the switching circuit can be coupled to the third port C of the switching circuit, so that the communication chip 40 can be coupled to the first feed radiator 11 through the first filter unit 51, and the communication chip 40 can transmit or receive radio frequency signals of the first frequency band through the first feed radiator 11.

[0091] At the second moment, the first port A of the switching circuit can be coupled to the fourth port D of the switching circuit, so that the communication chip 40 can be coupled to the second feed radiator 12 through the first filter unit 51, and the communication chip 40 can transmit or receive radio frequency signals of the first frequency band through the second feed radiator 12.

[0092] At the third moment, the second port B of the switching circuit can be coupled to the third port C of the switching circuit, so that the communication chip 40 can be coupled to the first feed radiator 11 through the second filter unit 52, and the communication chip 40 can transmit or receive radio frequency signals of the second frequency band through the first feed radiator 11.

[0093] At the fourth moment, the second port B of the switching circuit can be coupled to the fourth port D of the switching circuit, so that the communication chip 40 can be coupled to the second feed radiator 12 through the second filter unit 52, and the communication chip 40 can transmit or receive radio frequency signals of the second frequency band through the second feed radiator 12.

[0094] In summary, the switching circuit 20 can enable the communication chip 40 to switch between the first frequency band and the second frequency band, and can also enable the communication chip 40 to switch between the first feed radiator 11 and the second feed radiator 12.

[0095] Furthermore, the communication component may also include a bypass switch 55, and the switching circuit 20 may include a first switch 21 and a second switch 22.

[0096] The first port of the first switch 21 can be reused as the first port A of the switching circuit, the second port of the first switch 21 can be reused as the second port B of the switching circuit, the first switch 21 can be coupled to the second switch 22 through the bypass switch 55, the third port of the second switch 22 can be reused as the third port C of the switching circuit, and the fourth port of the second switch 22 can be reused as the fourth port D of the switching circuit.

[0097] At either a first or second moment, the first filtering unit 51 can be coupled to the bypass switch 55 via the first switch 21, and the bypass switch 55 can be coupled to the first feed radiator 11 or the second feed radiator 12 via the second switch 22. The communication chip 40 can transmit the radio frequency signal of the first frequency band to the first feed radiator 11 or the second feed radiator 12 via the bypass switch 55, and then transmit it out via the first feed radiator 11 or the second feed radiator 12. Alternatively, the radio frequency signal of the first frequency band from the first feed radiator 11 or the second feed radiator 12 can be transmitted to the communication chip 40 via the bypass switch 55.

[0098] At the third or fourth moment, the second filtering unit 52 can be coupled to the bypass switch 55 via the first switch 21, and the bypass switch 55 can be coupled to the first feed radiator 11 or the second feed radiator 12 via the second switch 22. This allows the communication chip 40 to transmit the second-frequency radio frequency signal to the first feed radiator 11 or the second feed radiator 12 via the bypass switch 55, and then transmit it out via the first feed radiator 11 or the second feed radiator 12. Alternatively, the second-frequency radio frequency signal from the first feed radiator 11 or the second feed radiator 12 can be transmitted to the communication chip 40 via the bypass switch 55.

[0099] By setting the bypass switch 55, the power consumption of the RF path can be reduced.

[0100] Furthermore, referring to Figure 3, the communication component may further include a first low-noise amplifier (LNA) 54 and a second low-noise amplifier 56. The first switch 21 may also be coupled to the second switch 22 through the first low-noise amplifier 54 and the second low-noise amplifier 56.

[0101] At a first moment or a second moment, the first filter unit 51 can be coupled to the first low-noise amplifier 54 through the first switch 21, and the first low-noise amplifier 54 can be coupled to the first feed radiator 11 or the second feed radiator 12 through the second switch 22. The first low-noise amplifier 54 can be used to amplify the radio frequency signal of the first frequency band received from the first feed radiator 11 or the second feed radiator 12 and transmit it to the communication chip 40.

[0102] At the third or fourth moment, the second filter unit 52 can be coupled to the second low-noise amplifier 56 through the first switch 21, and the second low-noise amplifier 56 can be coupled to the first feed radiator 11 or the second feed radiator 12 through the second switch 22. The second low-noise amplifier 56 can be used to amplify the second frequency band radio frequency signal received from the first feed radiator 11 or the second feed radiator 12 and transmit it to the communication chip 40.

[0103] Further, referring to FIG4, the communication component may also include a first power amplifier (PA) 53 and a second power amplifier 57. The first switch 21 is coupled to the second switch 22 through the first power amplifier 53 and the second power amplifier 57.

[0104] At either a first or second moment, the first filter unit 51 can be coupled to the first power amplifier 53 via the first switch 21, and the first power amplifier 53 can be coupled to the first feed radiator 11 or the second feed radiator 12 via the second switch 22. The first power amplifier 53 can be used to amplify the radio frequency signal of the first frequency band and transmit it to the first feed radiator 11 or the second feed radiator 12.

[0105] At the third or fourth moment, the second filter unit 52 can be coupled to the second power amplifier 57 via the first switch 21, and the second power amplifier 57 can be coupled to the first feed radiator 11 or the second feed radiator 12 via the second switch 22. The second power amplifier 57 can be used to amplify the radio frequency signal of the second frequency band and transmit it to the first feed radiator 11 or the second feed radiator 12.

[0106] In some embodiments, as shown in Figures 3 and 4, the wearable electronic device further includes a floor, and the communication components may include a first matching circuit 61 and a second matching circuit 62. The first matching circuit 61 includes a first matching device coupled between the first feed radiator 11 and the floor, and the second matching circuit 62 includes a second matching device coupled between the second feed radiator 12 and the floor.

[0107] For example, the first matching circuit 61 may include at least one grounding capacitor and / or at least one grounding inductor, and the second matching circuit 62 may include at least one grounding capacitor and / or at least one grounding inductor.

[0108] With the above configuration, the first feed radiator 11 can be grounded through the first matching circuit 61, which is used to adjust the frequency band of the first feed radiator 11. The second feed radiator 12 is grounded through the second matching circuit 62, which is used to adjust the frequency band of the second feed radiator 12.

[0109] When the communication chip 40 is coupled to the first feed radiator 11, the second feed radiator 12 cannot be completely disconnected because it is coupled to the second matching circuit 62. Similarly, when the communication chip 40 is coupled to the second feed radiator 12, the first feed radiator 11 cannot be completely disconnected because it is coupled to the first matching circuit 61. Because the housing of wearable electronic devices is small, the physical distance between the first feed radiator 11 and the second feed radiator 12 is close, resulting in low isolation between them. Consequently, the antenna efficiency of the second feed radiator 12 and the first feed radiator 11 will affect each other.

[0110] Furthermore, the communication component may also include a first tuning circuit 31 and a second tuning circuit 32.

[0111] The connection methods of the first tuning circuit 31 and the second tuning circuit 32 with the switching circuit 20 shown in Figures 3 and 4 are merely exemplary, and the embodiments of this application do not impose specific limitations on them. In some embodiments, the first tuning circuit 31 can be coupled to the first feed radiator 11 through a switch, and the second tuning circuit 32 can be coupled to the second feed radiator 12 through a switch. The two switches can have structures different from those of the switching circuit 20. Alternatively, as shown in Figures 3 and 4, the two switches can also be reused as the second switch 22 of the switching circuit 20.

[0112] In some embodiments, the first tuning circuit 31 may include a first tuning device, and the second tuning circuit 32 may include a second tuning device. The first tuning device may be coupled between the first feed radiator 11 and the ground plane. For example, one end of the first tuning device may be coupled to the first feed radiator 11 via a switching circuit 20, and the other end of the first tuning device may be coupled to the ground plane. The second tuning device may be coupled between the second feed radiator 12 and the ground plane. For example, one end of the second tuning device may be coupled to the second feed radiator 12 via a switching circuit 20, and the other end of the second tuning device may be coupled to the ground plane.

[0113] In one embodiment, the tuning device is used to ground the radiator to adjust the electrical length of the radiator (e.g., by adjusting the electrical length using a capacitor or inductor). In another embodiment, the tuning device is used to ground the radiator so that the resonant point of the radiator does not affect another radiator that is operating (e.g., the resonant point of the radiator is off-center from the operating communication frequency band (a first band or a second band)).

[0114] For example, both the first tuning circuit 31 and the second tuning circuit 32 can be coupled to the second switch 22 of the switching circuit 20. The first tuning device may include at least one ground inductor and / or ground capacitor, and the second tuning device may include at least one ground inductor and / or ground capacitor. The isolation between the first feed radiator 11 and the second feed radiator 12 can be adjusted by adjusting the capacitance or inductance value.

[0115] When the communication chip 40 is coupled to the first feed radiator 11, the second feed radiator 12 is coupled to the second tuning circuit 32. For example, the communication chip 40 disconnects from the second feed radiator 12 via a switch, and the second feed radiator 12 is coupled to the second tuning circuit 32 via a switch.

[0116] For example, when the communication component is coupled to the first feed radiator 11 through the first switch 21 and the second switch 22, one end of the second tuning device can be coupled to the second feed radiator 12 through the second switch 22, and the other end of the second tuning device can be coupled to the ground, so that the second feed radiator 12 is grounded through the second tuning device, thereby adjusting the isolation between the first feed radiator 11 and the second feed radiator 12.

[0117] When the communication chip 40 is coupled to the second feed radiator 12, the first feed radiator 11 is coupled to the first tuning circuit 31. For example, the communication chip 40 disconnects from the first feed radiator 11 via a switch, and the first feed radiator 11 is coupled to the first tuning circuit 31 via a switch.

[0118] For example, when the communication component is coupled to the second feed radiator 12 through the first switch 21 and the second switch 22, one end of the first tuning device can be coupled to the first feed radiator 11 through the second switch 22, and the other end of the first tuning device can be coupled to the ground, so that the first feed radiator 11 is grounded through the second tuning device, thereby adjusting the isolation between the first feed radiator 11 and the second feed radiator 12.

[0119] In some other embodiments, the first tuning device may also include other grounding devices, and the second tuning device may also include other grounding devices; however, this application does not limit the scope of the embodiments.

[0120] This application also provides a communication control method for a wearable electronic device, applied to the wearable electronic device described in the above embodiments. Referring to FIG5, and in conjunction with FIGS. 3 and 4, the method may include S1-S3:

[0121] S1. Obtain the first interference information of the first frequency band and the second interference information of the second frequency band.

[0122] In this embodiment of the application, the communication chip 40 can be coupled with the first feed radiator 11 or the second feed radiator 12 at times other than the first time, the second time, the third time and the fourth time to obtain the first interference information of the first frequency band and the second interference information of the second frequency band.

[0123] In some embodiments, the first interference information includes at least one of signal interference intensity, packet error rate, retransmission rate, and signal-to-noise ratio; the second interference information includes at least one of signal interference intensity, packet error rate, retransmission rate, and signal-to-noise ratio. The first interference information is used to characterize the interference intensity experienced by the wearable electronic device when communicating in a first frequency band, and the second interference information is used to characterize the interference intensity experienced by the wearable electronic device when communicating in a second frequency band.

[0124] The embodiments of this application do not specifically limit the first interference information and the second interference information, and the first interference information and the second interference information may also include other information types.

[0125] S2. Based on the first interference information and the second interference information, the communication chip communicates via radio frequency signals of the first frequency band or the second frequency band.

[0126] Taking the first interference information including signal interference intensity and the second interference information including signal interference intensity as an example, when the signal interference intensity of the first frequency band is greater than that of the second frequency band, the wearable electronic device is subjected to stronger interference when communicating in the first frequency band. The communication chip 40 can be switched to couple with the second filter unit 52 so that the communication chip 40 can be used to transmit or receive radio frequency signals in the second frequency band.

[0127] Conversely, when the signal interference intensity of the first frequency band is less than that of the second frequency band, the wearable electronic device experiences stronger interference when communicating in the second frequency band. The communication chip 40 can then switch to couple with the first filter unit 51 so that the communication chip 40 can be used to transmit or receive radio frequency signals in the first frequency band.

[0128] S3. The communication chip communicates through the first feed radiator or the second feed radiator.

[0129] In some embodiments, referring to FIG6, the first feed radiator 11 can be a dual-band antenna that transmits and receives radio frequency signals in the first frequency band and the second frequency band, and the second feed radiator 12 can be a single-band antenna that transmits and receives radio frequency signals in the first frequency band.

[0130] When the communication chip 40 communicates in the second frequency band, the communication chip 40 can switch to coupling with the first feed radiator 11 so that the communication chip 40 can transmit or receive radio frequency signals in the second frequency band through the first feed radiator 11.

[0131] When the communication chip 40 communicates within the first frequency band, the communication chip communicating through the first feed radiator or the second feed radiator may include:

[0132] The communication chip 40 acquires first signal information from the first feed radiator 11 and second signal information from the second feed radiator 12. In some embodiments, the communication chip 40 can acquire the first signal information through the first feed radiator 11 and the second signal information through the second feed radiator 12.

[0133] In some embodiments, the first signal information includes at least one of Received Signal Strength Indication (RSSI), packet error ratio (PER), retransmission rate, and signal-to-noise ratio; the second signal information includes at least one of signal strength, packet error ratio, retransmission rate, and signal-to-noise ratio. This application does not specifically limit the first and second signal information; the first and second signal information may also include other information types.

[0134] Based on the first signal information and the second signal information, the communication chip 40 is coupled to the first feed radiator or the second feed radiator.

[0135] Taking the first signal information including signal strength and the second signal information including signal strength as an example, when the signal strength of the first feed radiator 11 is greater than the signal strength of the second feed radiator 12, the communication performance of the first feed radiator 11 as an antenna is better. The communication chip 40 can switch to coupling with the first feed radiator 11 so that the communication chip 40 can transmit or receive radio frequency signals of the first frequency band through the first feed radiator 11.

[0136] Conversely, when the signal strength of the first feed radiator 11 is less than that of the second feed radiator 12, the second feed radiator 12 has better communication performance when used as an antenna. The communication chip 40 can switch to couple with the second feed radiator 12 so that the communication chip 40 can transmit or receive radio frequency signals of the first frequency band through the second feed radiator 12.

[0137] In some other embodiments, referring to FIG7, the first feed radiator 11 can be a dual-band antenna that transmits and receives radio frequency signals in the first frequency band and radio frequency signals in the second frequency band, and the second feed radiator 12 can also be a dual-band antenna that transmits and receives radio frequency signals in the first frequency band and radio frequency signals in the second frequency band.

[0138] Taking the example of the first signal information including signal strength and the second signal information including signal strength, when the communication chip 40 communicates in the first frequency band, the communication chip 40 can switch to communicate through the first feed radiator 11 or the second feed radiator 12. The communication method is as described in the above embodiment and will not be repeated here.

[0139] When the communication chip 40 communicates in the second frequency band, when the signal strength of the first feed radiator 11 is greater than the signal strength of the second feed radiator 12, the communication performance of the first feed radiator 11 as an antenna is better. The communication chip 40 can switch to coupling with the first feed radiator 11 so that the communication chip 40 can transmit or receive radio frequency signals in the second frequency band through the first feed radiator 11.

[0140] Conversely, when the signal strength of the first feed radiator 11 is less than the signal strength of the second feed radiator 12, the second feed radiator 12 has better communication performance when used as an antenna. The communication chip 40 can switch to couple with the second feed radiator 12 so that the communication chip 40 can transmit or receive radio frequency signals of the second frequency band through the second feed radiator 12.

[0141] This application also provides a wearable electronic device. Referring to FIG8, the electronic device may include a housing, a first feed radiator 11, and a second feed radiator 12. The first feed radiator 11 and the second feed radiator 12 may be disposed on the housing. The connection method between the first feed radiator 11 and the second feed radiator 12 and the housing can be as described in the above embodiments, and will not be repeated here. The first feed radiator 11 can be used to transmit or receive radio frequency signals in a first frequency band, and the second feed radiator 12 can be used to transmit or receive radio frequency signals in the first frequency band.

[0142] The electronic device may also include a communication component, which may be located within a predetermined area enclosed by the housing. The communication component may include a communication chip 40, a first tuning circuit 31, and a second tuning circuit 32. For example, the communication component may include a first filtering unit 51 and a switching circuit 20. The first filtering unit 51 may be coupled to the switching circuit 20. The first filtering unit 51 may be as described in the above embodiments, and will not be repeated here.

[0143] In some embodiments, the wearable electronic device further includes a floor, and the communication components may include a first matching circuit 61 and a second matching circuit 62. The first matching circuit 61 includes a first matching device, and the second matching circuit 62 includes a second matching device. The first matching device is coupled between the first feed radiator 11 and the floor, and the second matching device is coupled between the second feed radiator 12 and the floor. The first matching circuit 61 and the second matching circuit 62 can be as described in the above embodiments, and will not be repeated here.

[0144] Furthermore, when the communication chip 40 is coupled to the first feed radiator 11: the communication chip 40 disconnects from the second feed radiator 12 via a switch, and the second feed radiator 12 is coupled to the second tuning circuit via a switch. When the communication chip 40 is coupled to the second feed radiator 12: the communication chip 40 disconnects from the first feed radiator 11 via a switch, and the first feed radiator 11 is coupled to the first tuning circuit via a switch. The switch can be reused as a switching circuit 20.

[0145] For example, both the first tuning circuit 31 and the second tuning circuit 32 can be coupled to the switching circuit 20. When the communication component is coupled to the first feed radiator 11 through the switching circuit 20, the second tuning circuit 32 can be coupled to the second feed radiator 12 through the switching circuit 20, thereby adjusting the isolation between the first feed radiator 11 and the second feed radiator 12.

[0146] Similarly, when the communication component is coupled to the second feed radiator 12 via the switching circuit 20, the first tuning circuit 31 can be coupled to the first feed radiator 11 via the switching circuit 20, thereby adjusting the isolation between the first feed radiator 11 and the second feed radiator 12.

[0147] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
