Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to an electronic device and an antenna. Background Technology

[0002] In wireless communication systems of electronic devices, the fusion of wireless communication and sensing can bring about more application demands. The fusion of wireless communication and sensing means that electronic devices possess both wireless communication and sensing capabilities. That is, while providing wireless communication capabilities, electronic devices also incorporate radar-like functions (sensing capabilities), enabling them to sense and detect surrounding objects such as people, equipment (drones, cars, or ships).

[0003] To reduce network construction costs and improve communication and sensing experience, it is crucial for sensing systems to share hardware with wireless communication systems. However, traditional wireless communication systems use orthogonal linearly polarized antennas. When applied to sensing systems, considering polarization matching of reflectors, only co-polarized antennas can be used for sensing. Therefore, dedicated antennas and RF channels are required for the sensing system, resulting in hardware waste. Furthermore, the self-interference of co-polarized antennas also degrades the sensing experience. Utility Model Content

[0004] This application provides an electronic device and antenna that allows the electronic device to directly reuse all antennas and radio frequency channels to realize the wireless communication function and sensing function of the electronic device, thus avoiding hardware waste.

[0005] In a first aspect, an electronic device is provided, comprising: at least two radio frequency (RF) channels and at least two antennas; the at least two RF channels include: a first RF channel and a second RF channel; the at least two antennas include: a first antenna and a second antenna; the first RF channel is coupled to the first antenna, and the second RF channel is coupled to the second antenna; wherein the first antenna and the second antenna are both circularly polarized antennas, and the polarization of the first antenna and the second antenna are different. For example, the first antenna uses left-hand circular polarization, and the second antenna uses right-hand circular polarization; or, the first antenna uses right-hand circular polarization, and the second antenna uses left-hand circular polarization.

[0006] In this way, when implementing wireless communication, the electronic device can output radio frequency signals to two antennas through two separate radio frequency channels, thereby transmitting radio frequency signals to other electronic devices. Furthermore, it can also receive radio frequency signals from two antennas through two separate radio frequency channels, thereby receiving radio frequency signals transmitted by other electronic devices. Alternatively, when implementing sensing functionality, a radio frequency signal can be transmitted to a first antenna through a first radio frequency channel. This radio frequency signal, after being reflected by the sensing object, is then received by a second radio frequency channel through a second antenna. Typically, the polarization of the circularly polarized signal in the radio frequency (RF) signal output by an antenna depends on the antenna's polarization. For example, if the antenna is polarized left-handed circularly, the output RF signal will contain left-handed circularly polarized signals; conversely, if the antenna is polarized right-handed circularly, the output RF signal will contain right-handed circularly polarized signals. Similarly, the polarization of the circularly polarized signal in the RF signal received by an antenna depends on the antenna's polarization. For example, if the antenna is polarized left-handed circularly, the received RF signal will contain left-handed circularly polarized signals; conversely, if the antenna is polarized right-handed circularly, the received RF signal will contain right-handed circularly polarized signals. Therefore, the aforementioned electronic device can normally achieve wireless communication capabilities. Furthermore, when implementing the sensing function, the left-hand circularly polarized radio frequency signal output by the first antenna is reflected by the sensing object and becomes right-hand circularly polarized, which is then received by the second antenna; or the right-hand circularly polarized radio frequency signal output by the first antenna is reflected by the sensing object and becomes left-hand circularly polarized, which is then received by the second antenna. Therefore, the simultaneous reception or transmission of radio frequency signals in the sensing function can be achieved.

[0007] Therefore, the first and second antennas can normally realize wireless communication and sensing functions. In realizing wireless communication and sensing functions, the electronic device directly reuses all antennas and radio frequency channels, avoiding hardware waste. In addition, since the polarization of the first and second antennas is different, the first antenna can only receive the radio frequency signal reflected by the sensed object. The polarization of the radio frequency signal transmitted by the second antenna does not match the polarization of the second antenna, so it cannot receive the radio frequency signal directly transmitted by the first antenna. This also avoids the self-interference caused by the radio frequency signal directly transmitted by the first antenna to the second antenna receiving the radio frequency signal reflected by the sensed object.

[0008] In one possible implementation, a first radio frequency (RF) channel is configured to output a first RF signal via a first antenna in a first mode, and a second RF channel is configured to receive a second RF signal via a second antenna in the first mode; wherein the first RF signal includes a first circularly polarized signal, the second RF signal includes a second circularly polarized signal, and the polarization modes of the first and second circularly polarized signals are different. This possible implementation achieves the output and reception of RF signals for the sensing function of the electronic device.

[0009] In one possible implementation, a first radio frequency (RF) channel is configured to output a third RF signal via the first antenna in a second mode, and a second RF channel is configured to output a fourth RF signal via the second antenna in the second mode; wherein the third RF signal includes a third circularly polarized signal, the fourth RF signal includes a fourth circularly polarized signal, and the polarization of the third and fourth circularly polarized signals is different. This possible implementation achieves the RF signal output for the wireless communication function of the electronic device.

[0010] In one possible implementation, a first radio frequency (RF) channel is configured to receive a fifth RF signal via a first antenna in a third mode, and a second RF channel is configured to receive a sixth RF signal via a second antenna in the third mode; wherein the fifth RF signal includes a fifth circularly polarized signal, the sixth RF signal includes a sixth circularly polarized signal, and the polarization patterns of the fifth and sixth circularly polarized signals are different. This possible implementation achieves the reception of RF signals for the wireless communication function of the electronic device.

[0011] In one possible implementation, the first radio frequency channel includes a first transmit link and a first receive link; the second radio frequency channel includes a second transmit link and a second receive link; the electronic device further includes a first switch and a second switch; wherein, the first transmit link is coupled to a first selector terminal of the first switch, the first receive link is coupled to a second selector terminal of the first switch, and the first antenna is coupled to a common terminal of the first switch; the second transmit link is coupled to a first selector terminal of the second switch, the second receive link is coupled to a second selector terminal of the second switch, and the second antenna is coupled to a common terminal of the second switch. In this possible implementation, when implementing the wireless communication function, the first transmitting link can be connected to the first antenna and the second transmitting link can be connected to the second antenna via the first switch and the second switch, respectively, to transmit radio frequency signals to other electronic devices; the first receiving link can be connected to the first antenna and the second receiving link can be connected to the second antenna via the first switch and the second switch, respectively, to receive radio frequency signals from other electronic devices; or when implementing the sensing function, the first transmitting link can be connected to the first antenna and the second receiving link can be connected to the second antenna via the first switch and the second switch, respectively, so that electronic devices can transmit radio frequency signals to the first antenna via the first transmitting link, and the radio frequency signals are received by the second receiving link via the second antenna after being reflected by the sensing object.

[0012] In one possible implementation, the antenna includes a first substrate and a second substrate stacked vertically; wherein the first substrate is horizontally disposed, and the second substrate is perpendicular to the first substrate; the first substrate includes a first feed point disposed on a first side of the first substrate and a first vibrator connected to the first feed point; the second substrate includes a second feed point disposed on a first side of the second substrate and a second vibrator connected to the second feed point; the second substrate also includes a feed network disposed on a first side of the second substrate, the feed network having an input terminal, a first feed terminal, and a second feed terminal; the first feed point is coupled to the first feed terminal, and the second feed point is coupled to the second feed terminal; wherein a first path between the input terminal and the first feed terminal and a second path between the input terminal and the second feed terminal have a predetermined phase difference. In this way, the antenna described above can simultaneously excite the first vibrator on the horizontally arranged first substrate and the second vibrator on the vertically arranged second substrate through a feeding network. Since the feeding excitation signal (RF signal) can be input from the same input terminal and transmitted through the first path and the second path respectively to achieve a predetermined phase difference, the circularly polarized signal is finally synthesized on the two vibrators. This antenna sets the feeding network and the second vibrator together on a vertical substrate and sets the first vibrator on a horizontal substrate, which is compact and conducive to the miniaturization of the device.

[0013] In one possible implementation, the first oscillator includes: at least two first arms; each first arm includes a first conductive portion and a second conductive portion; wherein a first end of the first conductive portion is coupled to a first feed point, and a second end of the first conductive portion extends in a radial direction centered on the first feed point; the second end of the first conductive portion is connected to the first end of the second conductive portion, the second end of the second conductive portion is a free end, and the second conductive portion extends along an arc centered on the first feed point and with the first conductive portion as its radius; the second conductive portions of at least two first arms extend either clockwise or counterclockwise. Thus, when an excitation signal is input to the first oscillator through the feed network, a current will be generated on the first arms and transmitted along the first and second conductive portions to synthesize a circularly polarized signal.

[0014] In one possible implementation, the second oscillator includes at least one monopole connected to a second feed point. When an excitation signal is input to the second oscillator through the feed network, the current on the second oscillator propagates primarily in a direction perpendicular to the ground plane to synthesize a circularly polarized signal.

[0015] In one possible implementation, the feed network includes a first impedance adjustment structure disposed between the input terminal and the first feed terminal, and a second impedance adjustment structure disposed between the input terminal and the second feed terminal. The first and second impedance adjustment structures can respectively adjust the phase difference and impedance between the excitation signals introduced into the first and second oscillators. In some examples, to ensure the bandwidth of the antenna and the effectiveness of the circularly polarized signal, the phase difference can be 90° ± α, where α is a sufficiently small error, for example, α less than or equal to 5°.

[0016] In one possible implementation, the first impedance adjustment structure and / or the second impedance adjustment structure include a phase shifter. The phase shifter is used to shift the phase of the signals on the first path and the second path to achieve the predetermined phase difference mentioned above.

[0017] In one possible implementation, the antenna further includes a third substrate, wherein the third substrate is disposed on the side of the second substrate away from the first substrate, and the second substrate is disposed perpendicular to the third substrate; the first substrate further includes a third feed point disposed on a second side of the first substrate and a third vibrator connected to the third feed point; the second substrate includes a first conductive layer disposed on a second side of the second substrate; the third substrate includes a second conductive layer disposed on the third substrate, wherein the second conductive layer is used for grounding; the third feed point is coupled to the second conductive layer through the first conductive layer. Thus, the second conductive layer of the third substrate provides a grounding ground for the antenna, wherein the aforementioned vertical and horizontal properties are relative to the grounding ground provided by the third substrate, i.e., the first substrate, as a horizontal substrate, is horizontal to the grounding ground provided by the third substrate, and the second substrate, as a vertical substrate, is perpendicular to the grounding ground provided by the third substrate.

[0018] In one possible implementation, the third oscillator includes: at least two second arms; each second arm includes a third conductive portion and a fourth conductive portion, wherein a first end of the third conductive portion is coupled to the third feed point, and a second end of the fourth conductive portion extends in a radial direction centered on the third feed point; the second end of the third conductive portion is connected to the first end of the fourth conductive portion, the second end of the fourth conductive portion is a free end, and the fourth conductive portion extends along an arc centered on the third feed point and with the third conductive portion as its radius; the fourth conductive portions of at least two second arms extend either counterclockwise or clockwise. Thus, when an excitation signal is input to the first oscillator through the feeding network, currents are generated on the second arm, traveling along the third and fourth conductive portions. Since the second arm of the third oscillator is connected to the ground, the current generated on the second arm along the third conductive portion is in the opposite direction to the current generated on the first arm along the first conductive portion. Furthermore, since the extension direction of the fourth conductive portion of the second arm is opposite to the extension direction of the second conductive portion of the first arm, the current generated on the fourth conductive portion of the second arm is in the same direction as the current generated on the second conductive portion of the first arm. In this way, in the horizontal direction, the electric field generated by the current along the third conductive portion of the second arm can cancel out the electric field generated by the current along the first conductive portion of the first arm. The electric field generated by the current along the fourth conductive portion of the second arm is continuous with the electric field generated by the current along the second conductive portion of the first arm, thus more effectively combining the current in the vertical direction with the current transmitted on the second oscillator to synthesize a circularly polarized signal.

[0019] In one possible implementation, the third oscillator includes a ring-shaped fifth conductive portion, which is disposed around and connected to the third feed point. In this way, the fifth conductive portion can also effectively shield the electric field formed by the radial current along the first conductive portion on the first arm.

[0020] In one possible implementation, a first end of the first conductive layer is connected to a third feed point; a second end of the first conductive layer is connected to a second conductive layer. Here, the second end of the first conductive layer and the second conductive layer can be directly connected, for example, by soldering.

[0021] In one possible implementation, the first conductive layer includes a connecting portion and a coupling portion. A first end of the connecting portion is connected to a third feed point, and a second end of the connecting portion is connected to the coupling portion. A gap exists between the coupling portion and the third substrate. Since the radio frequency signal transmitted by the antenna is typically an AC high-frequency signal, utilizing the AC conduction characteristic of a capacitor, it is not necessary to solder the first conductive layer to the second conductive layer on the third substrate. Instead, the coupling portion, the second conductive layer of the third substrate, and the gap between the coupling portion and the third substrate can be used as the two electrodes of the capacitor to achieve coupling between the first and second conductive layers. This reduces the complexity of the assembly process.

[0023] In one possible implementation, the first oscillator includes: at least two first arms; each first arm includes a first conductive portion and a second conductive portion, wherein a first end of the first conductive portion is coupled to a first feed point, and a second end of the first conductive portion extends in a radial direction centered on the first feed point; the second end of the first conductive portion is connected to the first end of the second conductive portion, the second end of the second conductive portion is a free end, and the second conductive portion extends along an arc centered on the first feed point and with the first conductive portion as its radius; the second conductive portions of the at least two first arms extend either clockwise or counterclockwise.

[0024] In one possible implementation, the second oscillator includes at least one monopole connected to the second feed point.

[0025] In one possible implementation, the power supply network includes: a first impedance adjustment structure disposed between the input terminal and the first power supply terminal, and a second impedance adjustment structure disposed between the input terminal and the second power supply terminal.

[0026] In one possible implementation, the first impedance adjustment structure and / or the second impedance adjustment structure include a phase shifter.

[0027] In one possible implementation, the antenna further includes a third substrate, wherein the third substrate is disposed on the side of the second substrate away from the first substrate, and the second substrate is disposed perpendicular to the third substrate; the first substrate further includes a third feed point disposed on a second side of the first substrate and a third vibrator connected to the third feed point; the second substrate includes a first conductive layer disposed on a second side of the second substrate; the third substrate includes a second conductive layer disposed on the third substrate, wherein the second conductive layer is used for grounding; the third feed point is coupled to the second conductive layer through the first conductive layer.

[0028] In one possible implementation, the third oscillator includes: at least two second arms; each second arm includes a third conductive portion and a fourth conductive portion, wherein a first end of the third conductive portion is coupled to a third feed point, and a second end of the fourth conductive portion extends in a radial direction centered on the third feed point; the second end of the third conductive portion is connected to the first end of the fourth conductive portion, the second end of the fourth conductive portion is a free end, and the fourth conductive portion extends along an arc centered on the third feed point with the third conductive portion as its radius; the fourth conductive portions of at least two second arms extend either counterclockwise or clockwise.

[0029] In one possible implementation, the third oscillator includes a ring-shaped fifth conductive portion disposed around and connected to the third feed point.

[0030] In one possible implementation, a first end of the first conductive layer is connected to a third feed point; and a second end of the first conductive layer is connected to a second conductive layer.

[0031] In one possible implementation, the first conductive layer includes a connecting portion and a coupling portion, with a first end of the connecting portion connected to a third feed point and a second end of the connecting portion connected to the coupling portion; a gap exists between the coupling portion and the third substrate.

Detailed Implementation

[0041] 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.

[0042] In the following description, the terms "first," "second," etc., are used for descriptive convenience 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. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0043] The term "coupling" should be interpreted broadly. For example, "coupling" can refer to a direct electrical connection, such as physical contact and electrical conduction between two components. It can also be understood as the electrical 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), to transmit electrical signals. Alternatively, "coupling" can refer to an indirect electrical connection between two components through an intermediate medium. Or, "coupling" can refer to an electrical connection between two components in a non-contact manner, such as a capacitive coupling between two components to transmit electrical signals.

[0044] In this embodiment of the application, "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0045] A radio frequency integrated circuit (RFIC) is a combination of all components of an antenna used for receiving and transmitting radio frequency waves. In the case of a receiving antenna, the RFIC can be considered the antenna section from the first amplifier to the front-end transmitter. In a transmitting antenna, the RFIC can be seen as the section after the last power amplifier. In some cases, the RFIC can also be understood as a feed unit. The RFIC has the function of converting radio waves into electrical signals and sending them to the receiver components. Typically, it is considered part of the antenna system used to convert radio waves into electrical signals and vice versa.

[0046] Front-end modules (FEMs), also known as front-end circuits or radio frequency (RF) front-end circuits, typically consist of amplifiers (e.g., power amplifiers (PAs), low-noise amplifiers (LNAs), filters (or duplexers), and switches. Based on the hardware in these front-end modules, they provide the necessary front-end channels (amplification, filtering) and selection functions for each different communication standard. In some examples, the RF chip and the front-end module together constitute the RF channel provided in the embodiments of this application.

[0047] Radiator: In an antenna, this is the device 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, referred to as radio frequency signal in the embodiments of this application) generated by the transmitter is transmitted to the transmitting radiator via a feed line, where it is converted into electromagnetic wave energy of a certain polarization and radiated in the desired direction. The receiving radiator converts electromagnetic wave energy of a certain polarization from a specific direction in space into modulated high-frequency current energy, which is then transmitted to the receiver input via a feed line.

[0048] dB: This stands for decibel, a logarithmic concept with base 10. Decibels are only used to evaluate the proportional relationship between two physical quantities; they themselves have no physical dimensions. For every 10-fold increase in the ratio between two quantities, their difference can be expressed as 10 dB. For example: A = 100, B = 10, C = 5, D = 1, then A / D = 20 dB; B / D = 10 dB; C / D = 7 dB; B / C = 3 dB. That is, a 10 dB difference between two quantities is a 10-fold difference, a 20 dB difference is a 100-fold difference, and so on. A 3 dB difference is a 2-fold difference between the two quantities.

[0049] Linear polarization: Electromagnetic waves in which the orientation of the electric field vector remains fixed in space are called linearly polarized. Using the ground (also called the floor, reference ground GND, etc.) as a parameter, electric field vectors parallel to the ground are called horizontally polarized, and electric field vectors perpendicular to the ground are called vertically polarized. Antennas that generate electromagnetic waves using linear polarization are also called linearly polarized antennas.

[0050] Circular polarization: When the angle between the polarization plane of a radio wave and the normal plane of the earth changes periodically from 0° to 360°, meaning the magnitude of the electric field remains constant while its direction changes with time, and the trajectory of the end of the electric field vector projects as a circle on a plane perpendicular to the propagation direction, it is called circular polarization. Circular polarization can be achieved when the horizontal and vertical components of the electric field have equal amplitudes and a phase difference of 90° or 270°. If the polarization plane of circular polarization rotates with time and forms a right-handed spiral relationship with the direction of electromagnetic wave propagation, it is called right-handed circular polarization (RHCP); conversely, if it forms a left-handed spiral relationship, it is called left-handed circular polarization (LHCP). Antennas that generate electromagnetic waves using circular polarization are also called circularly polarized antennas.

For example... Figure 1 As shown, depending on the communication standard, electronic device 1 can communicate with electronic device 2 via cellular means, via satellite, or via non-cellular (NC) communication with other nearby structures such as electronic device 2, to meet the usage requirements in different scenarios and thus achieve wireless communication functionality. Furthermore, electronic device 1 can also achieve sensing functionality by sending radio frequency signals to the sensing object and receiving the radio frequency signals reflected by the sensing object.

[0053] Cellular communication is a type of terrestrial communication, and includes technologies such as 2G (2nd generation wireless systems), 3G, 4G, 5G, 5.5G, 6G, and future communication technologies. When implementing cellular communication in these scenarios, electronic device 1 can be a base station, and electronic device 2 can be a mobile phone or other terminal device. Non-cellular communication also falls under the category of terrestrial communication, and includes technologies such as Wireless Fidelity (WiFi), Bluetooth (BT), Bluetooth Low Energy (BLE), Near Link, Location Based Services (LBS), Global Positioning System (GPS), Near Field Communication (NFC), and Radio Frequency Identification (RFID). When implementing non-cellular communication based on the above communication scenarios, electronic device 1 can be an access point (AP) (e.g., a home wireless router, enterprise wireless Wi-Fi, etc.), and electronic device 2 can be a mobile phone, tablet, laptop, smart home device, smart bracelet, smartwatch, smart helmet, smart glasses, virtual reality (VR) terminal device, augmented reality (AR) terminal device, positioning device, etc. Satellite communication belongs to non-terrestrial network (NTN) communication, which can include geostationary earth orbit (GEO) satellite communication (also known as geostationary orbit communication satellite), medium earth orbit (MEO) satellite communication, and low earth orbit (LEO) satellite communication. When implementing satellite communication based on the above communication scenarios, electronic device 1 can be a satellite, and electronic device 2 can be a satellite phone, etc.

[0058] In addition, those skilled in the art will understand that the above Figure 2 The structure of the electronic device shown does not constitute a limitation on the electronic device. The electronic device may include more or fewer components than shown, or combine certain components, or have different component arrangements. For example, the electronic device may also include components such as a microphone, earpiece, speaker, input unit, sensor, audio circuit, wireless fidelity (WiFi) module, power supply, and Bluetooth module, which will not be described in detail here.

[0059] Based on the aforementioned electronic devices and communication scenarios, integrating wireless communication and sensing functions into a single electronic device can unlock greater application potential. By combining wireless communication and sensing capabilities, the electronic device can provide wireless communication while simultaneously incorporating radar-like functionality (sensing capabilities), enabling the detection and sensing of surrounding objects such as people, devices (drones, cars, or ships). To reduce network deployment costs and enhance the communication and sensing experience, it is crucial that the sensing system utilizes the same hardware as the wireless communication system. However, traditional wireless communication systems employ orthogonal linearly polarized antennas. When applied to sensing systems, considering polarization matching of reflectors, only co-polarized antennas can be used for sensing. This necessitates dedicated antennas and RF channels for the sensing system, resulting in hardware waste. Furthermore, the self-interference of co-polarized antennas also degrades the sensing experience.

[0060] For example, orthogonal linearly polarized antennas are commonly used in wireless communication systems. That is, if an electronic device includes only two antennas, one typically uses a first linear polarization, and the other a second linear polarization. This arrangement is chosen because linear polarization is simple and effectively reduces the size of the electronic device, especially given the current trend towards miniaturization. Furthermore, to reduce mutual interference between the radio frequency signals transmitted by different antennas, the two antennas usually employ different linear polarization methods. For example, the first linear polarization might be horizontal, and the second might be vertical, meaning the first and second linear polarizations are orthogonal.

[0061] However, for the electronic devices based on the two antennas mentioned above, if a sensing function is to be added, the polarization of the linearly polarized radio frequency signal remains unchanged after being reflected by the sensing object. Therefore, only two identical linearly polarized antennas can be used to implement the sensing function, and the two antennas (orthogonal linearly polarized antennas) mentioned above cannot be directly reused to implement the sensing function. Thus, a separate antenna and radio frequency channel need to be added for the sensing function, resulting in hardware waste.

[0062] To achieve the integration of wireless communication and sensing, based on Figures 3-5As shown, an electronic device with four antennas capable of implementing wireless communication and sensing is provided. The electronic device 100 includes four radio frequency channels and four antennas. The four radio frequency channels include radio frequency channel 1, radio frequency channel 2, radio frequency channel 3, and radio frequency channel 4; the four antennas include antennas ANT1-ANT4.

[0063] Each radio frequency (RF) channel includes a receive link (RX) and a transmit link (TX). For example, the transmit link 1 and receive link 1 of RF channel 1 are respectively connected to the two select terminals of switch K1, and the common terminal of switch K1 is connected to antenna ANT1. Thus, when control switch K1 connects transmit link 1 to antenna ANT1, electronic device 100 can output RF signals to antenna ANT1 through RF channel 1; when control switch K1 connects receive link 1 to antenna ANT1, electronic device 100 can receive RF signals from antenna ANT1 through RF channel 1. In addition, the transmit link 2 and receive link 2 of RF channel 2 are respectively connected to the two select terminals of switch K2, and the common terminal of switch K2 is connected to antenna ANT2; the transmit link 3 and receive link 3 of RF channel 3 are respectively connected to the two select terminals of switch K3, and the common terminal of switch K3 is connected to antenna ANT3; the transmit link 4 and receive link 4 of RF channel 4 are respectively connected to the two select terminals of switch K4, and the common terminal of switch K4 is connected to antenna ANT4; wherein, the electronic device receives or transmits RF signals through antennas ANT2-ANT4 in the same way as it receives or transmits RF signals through ANT1, and will not be described again here.

[0064] To enable both wireless communication and sensing functions on an electronic device 100, antennas ANT1 and ANT2 are typically configured with a first linear polarization, while antennas ANT3 and ANT4 are configured with a second linear polarization. The first and second linear polarizations differ; in some examples, they are preferably perpendicular (or orthogonal) to each other, for example, the first linear polarization is horizontal and the second linear polarization is vertical.

[0065] Thus, when electronic device 100 implements wireless communication functionality with electronic device 200, refer to Figure 3 As shown, transmit link 1 can be connected to antenna ANT1, transmit link 2 to antenna ANT2, transmit link 3 to antenna ANT3, and transmit link 4 to antenna ANT4 via switches K1-K4 respectively. The electronic device can then output radio frequency signals to the four antennas ANT1-ANT4 via radio frequency channels 1-4, thereby transmitting radio frequency signals to the electronic device 200. (Refer to...) Figure 4As shown, receiving link 1 can be connected to antenna ANT1, receiving link 2 to antenna ANT2, receiving link 3 to antenna ANT3, and receiving link 4 to antenna ANT4 via switches K1-K4 respectively. The electronic device can then receive radio frequency signals from the four antennas ANT1-ANT4 via radio frequency channels 1-4, thus realizing the reception of radio frequency signals from electronic device 200. When implementing the sensing function, refer to... Figure 5 As shown, the transmitting link 1 can be connected to antenna ANT1, the receiving link 2 to antenna ANT2, the receiving link 3 to antenna ANT3, and the receiving link 4 to antenna ANT4 via switches K1-K4 respectively. The electronic device can output an RF signal to antenna ANT1 through RF channel 1. This RF signal is reflected by the detected object and received by RF channel 2 through antenna ANT2. However, because antennas ANT3 (ANT4) and ANT1 (ANT2) have different polarizations, RF channels 3 and 4 cannot receive the RF signal reflected by the detected object. Thus, in a sensing scenario, RF channels 3 and 4, as well as antennas ANT3 and ANT4, represent wasted hardware. Furthermore, since antennas ANT1 and ANT2 have the same polarization, antenna ANT2 can receive not only the RF signal reflected by the detected object but also the RF signal directly transmitted by antenna ANT1. The RF signal directly transmitted by antenna ANT1 causes self-interference with the RF signal received by antenna ANT2 from the detected object, affecting the sensing experience.

[0066] Reference Figures 6-8 As shown, an electronic device 100 is provided, which includes at least two radio frequency channels and at least two antennas ANT.

[0067] In one example, at least two radio frequency (RF) channels include RF channel 1 and RF channel 2; at least two antennas (ANTs) include antenna ANT1 and antenna ANT2. RF channel 1 is coupled to the first antenna ANT1, and RF channel 2 is coupled to the second antenna ANT2; wherein both antenna ANT1 and antenna ANT2 are circularly polarized antennas, and antenna ANT1 and antenna ANT2 have different polarization methods. For example, antenna ANT1 uses left-hand circular polarization, and antenna ANT2 uses right-hand circular polarization; or, antenna ANT1 uses right-hand circular polarization, and antenna ANT2 uses left-hand circular polarization.

[0068] Specifically, refer to Figures 6-8As shown, each RF channel typically includes a receive link RX and a transmit link TX. For example, transmit link 1 and receive link 1 of RF channel 1 are respectively connected to the two select terminals of switch K1, and the common terminal of switch K1 is connected to antenna ANT1. Thus, when control switch K1 connects transmit link 1 to antenna ANT1, electronic device 100 can output RF signals to antenna ANT1 through RF channel 1; when control switch K1 connects receive link 1 to antenna ANT1, electronic device 100 can receive RF signals from antenna ANT1 through RF channel 1. Furthermore, transmit link 2 and receive link 2 of RF channel 2 are respectively connected to the two select terminals of switch K2, and the common terminal of switch K2 is connected to antenna ANT2. The way electronic device receives or transmits RF signals through antenna ANT2 is the same as the way it receives or transmits RF signals through ANT1, and will not be described further here.

[0069] Thus, when implementing wireless communication functions, refer to Figure 6 As shown, the transmit link 1 can be connected to antenna ANT1 and the transmit link 2 can be connected to antenna ANT2 via switches K1-K2 respectively. The electronic device can then output radio frequency (RF) signals to the two antennas ANT1-ANT2 via RF channels 1-2 respectively, thus transmitting RF signals to the electronic device 200. For example, RF channel 1 is configured to output a third RF signal via antenna ANT1 in a second mode, and RF channel 2 is configured to output a fourth RF signal via antenna ANT2 in a second mode. The third RF signal includes a third circularly polarized signal, and the fourth RF signal includes a fourth circularly polarized signal. The polarization modes of the third and fourth circularly polarized signals are different. For example, the polarization mode of the third circularly polarized signal is left-hand circularly polarized, and the polarization mode of the fourth circularly polarized signal is right-hand circularly polarized; or, the polarization mode of the third circularly polarized signal is right-hand circularly polarized, and the polarization mode of the fourth circularly polarized signal is left-hand circularly polarized. It can be understood that the polarization of the circularly polarized signal contained in the radio frequency signal output by the antenna depends on the polarization of the antenna. For example, if the antenna is polarized by left-hand circular polarization, the output radio frequency signal contains left-hand circularly polarized signals; conversely, if the antenna is polarized by right-hand circular polarization, the output radio frequency signal contains right-hand circularly polarized signals.

[0070] Reference Figure 7As shown, receiving link 1 can be connected to antenna ANT1 and receiving link 2 can be connected to antenna ANT2 via switches K1-K2 respectively. The electronic device can then receive radio frequency signals from the two antennas ANT1-ANT2 via radio frequency channels 1-2 respectively, thus receiving the radio frequency signals transmitted by the electronic device 200. For example, radio frequency channel 1 is configured to receive a fifth radio frequency signal via antenna ANT1 in a third mode, and radio frequency channel 2 is configured to receive a sixth radio frequency signal via antenna ANT2 in a third mode. The fifth radio frequency signal includes a fifth circularly polarized signal, and the sixth radio frequency signal includes a sixth circularly polarized signal. The polarization modes of the fifth and sixth circularly polarized signals are different. For example, the polarization mode of the fifth circularly polarized signal is left-hand circularly polarized, and the polarization mode of the sixth circularly polarized signal is right-hand circularly polarized; or, the polarization mode of the fifth circularly polarized signal is right-hand circularly polarized, and the polarization mode of the sixth circularly polarized signal is left-hand circularly polarized. It can be understood that the polarization of the circularly polarized signal contained in the radio frequency signal received by the antenna depends on the polarization of the antenna. For example, if the antenna is polarized by left-hand circular polarization, the received radio frequency signal contains left-hand circularly polarized signals; conversely, if the antenna is polarized by right-hand circular polarization, the received radio frequency signal contains right-hand circularly polarized signals.

[0071] When implementing the sensing function, refer to Figure 8As shown, the transmitting link 1 can be connected to antenna ANT1 and the receiving link 2 can be connected to antenna ANT2 via switches K1-K2 respectively. The electronic device can transmit a radio frequency (RF) signal to antenna ANT1 via RF channel 1. This RF signal is reflected by the sensing object and received by RF channel 2 via antenna ANT2. For example, RF channel 1 is configured to output a first RF signal via antenna ANT1 in a first mode, and RF channel 2 is configured to receive a second RF signal via antenna ANT2 in the first mode. The first RF signal includes a first circularly polarized signal, and the second RF signal includes a second circularly polarized signal. The polarization modes of the first and second circularly polarized signals are different. For example, the first circularly polarized signal may be left-hand circularly polarized, and the second circularly polarized signal may be right-hand circularly polarized; or, the first circularly polarized signal may be right-hand circularly polarized, and the second circularly polarized signal may be left-hand circularly polarized. Furthermore, since both antennas ANT1 and ANT2 are circularly polarized but with different polarization methods, the first radio frequency signal output by antenna ANT1 includes a first circularly polarized signal, and the second radio frequency signal generated by reflection from the sensing object includes a second circularly polarized signal which is received by antenna ANT2 (for example, a left-hand circularly polarized radio frequency signal becomes right-hand circularly polarized after reflection from the sensing object; or a right-hand circularly polarized radio frequency signal becomes left-hand circularly polarized after reflection from the sensing object). The first, second, and third modes mentioned above can be understood as different time periods or operating modes. That is, under different operating modes or time periods, each switch in the electronic device establishes different conduction states between each antenna and the corresponding transmit or receive link in the radio frequency channel, so as to realize time-division multiplexing of radio frequency signals for wireless communication, or simultaneous reception or transmission of radio frequency signals in sensing functions.

[0072] Therefore, antennas ANT1 and ANT2 can normally realize wireless communication and sensing functions. In realizing wireless communication and sensing functions, the electronic device directly reuses all antennas and radio frequency channels, avoiding hardware waste. In addition, since antennas ANT1 and ANT2 have different polarization modes, antenna ANT2 can only receive radio frequency signals reflected by the sensed object. The polarization mode of the radio frequency signal transmitted by antenna ANT1 does not match that of antenna ANT2, so it cannot receive the radio frequency signal directly transmitted by antenna ANT1. This also avoids the self-interference caused by the radio frequency signal directly transmitted by antenna ANT1 to the radio frequency signal received by antenna ANT2 from the sensed object.

[0073] Furthermore, based on Figures 9-13As shown, a method for implementing wireless communication and sensing via a four-antenna ANT electronic device 100 is also provided. The electronic device 100 includes four radio frequency channels and four antennas. The four radio frequency channels include radio frequency channel 1, radio frequency channel 2, radio frequency channel 3, and radio frequency channel 4, and the four antennas include antennas ANT1-ANT4.

[0074] Each radio frequency channel includes a receiving link RX and a transmitting link TX. For example, the transmitting link 1 and the receiving link 1 of radio frequency channel 1 are respectively connected to the two select terminals of switch K1, and the common terminal of switch K1 is connected to antenna ANT1. Thus, when control switch K1 connects the transmitting link 1 to antenna ANT1, electronic device 100 can output radio frequency signals to antenna ANT1 through radio frequency channel 1; when control switch K1 connects the receiving link 1 to antenna ANT1, electronic device 100 can receive radio frequency signals from antenna ANT1 through radio frequency channel 1. In addition, the transmit link 2 and receive link 2 of RF channel 2 are respectively connected to the two select terminals of switch K2, and the common terminal of switch K2 is connected to antenna ANT2; the transmit link 3 and receive link 3 of RF channel 3 are respectively connected to the two select terminals of switch K3, and the common terminal of switch K3 is connected to antenna ANT3; the transmit link 4 and receive link 4 of RF channel 4 are respectively connected to the two select terminals of switch K4, and the common terminal of switch K4 is connected to antenna ANT4; wherein, the way in which the electronic device receives or transmits RF signals through antennas ANT2-ANT4 is the same as the way in which it receives or transmits RF signals through ANT1, and will not be described again here.

[0075] In this configuration, antennas ANT1-ANT4 are all circularly polarized antennas, with antennas ANT1 and ANT2 exhibiting a first polarization, and antennas ANT3 and ANT4 exhibiting a second polarization. For example, antennas ANT1 and ANT2 may be left-hand circularly polarized, while antennas ANT3 and ANT4 may be right-hand circularly polarized; alternatively, antennas ANT1 and ANT2 may be right-hand circularly polarized, while antennas ANT3 and ANT4 may be left-hand circularly polarized.

[0076] Thus, when implementing wireless communication functions, refer to Figure 9 As shown, by switching K1-K4, transmit link 1 can be connected to antenna ANT1, transmit link 2 to antenna ANT2, transmit link 3 to antenna ANT3, and transmit link 4 to antenna ANT4, respectively. The electronic device can then output radio frequency signals to the four antennas ANT1-ANT4 via radio frequency channels 1-4, thus transmitting radio frequency signals to the electronic device 200. (Refer to...) Figure 10As shown, receiving link 1 can be connected to antenna ANT1, receiving link 2 to antenna ANT2, receiving link 3 to antenna ANT3, and receiving link 4 to antenna ANT4 respectively via switches K1-K4. The electronic device can receive radio frequency signals from the four antennas ANT1-ANT4 through radio frequency channels 1-4 respectively, thereby receiving radio frequency signals transmitted by the electronic device 200.

[0077] When implementing the sensing function, Figure 11 In this scheme, the electronic device can connect the transmitting link 1 to antenna ANT1, the receiving link 2 to antenna ANT2, the receiving link 3 to antenna ANT3, and the receiving link 4 to antenna ANT4 via switches K1-K4, respectively. The electronic device can output a radio frequency (RF) signal to antenna ANT1 via RF channel 1. This RF signal contains a first circularly polarized signal, which is reflected upon encountering a sensing object to form a second circularly polarized signal. This signal is received by the electronic device via antenna ANT3, coupled to RF channel 3, and antenna ANT4, coupled to RF channel 4, respectively. Furthermore, due to potential impurities in the polarization of antenna ANT1, the electronic device can also receive a small amount of reflected RF signal from the sensing object via antenna ANT2, coupled to RF channel 2. This creates a 1-transmit, 3-receive operating mode among the four antennas ANT1-ANT4.

[0078] exist Figure 12 In this scheme, the electronic device can connect transmit link 1 to antenna ANT1, transmit link 2 to antenna ANT2, receive link 3 to antenna ANT3, and receive link 4 to antenna ANT4 via switches K1-K4 respectively. The electronic device can output a first radio frequency (RF) signal to antenna ANT1 via RF channel 1 and a second RF signal to antenna ANT2 via RF channel 2. Both the first and second RF signals contain a first circularly polarized signal, which will be reflected upon encountering a sensing object to form a second circularly polarized signal. This signal is received by the electronic device via antenna ANT3 coupled to RF channel 3 and ANT4 coupled to RF channel 4 respectively. Thus, a 2-transmit, 2-receive working mode is formed among the four antennas ANT1-ANT4.

[0079] exist Figure 13In this scheme, the electronic device can connect the transmitting link 1 to antenna ANT1, the transmitting link 2 to antenna ANT2, the transmitting link 3 to antenna ANT3, and the receiving link 4 to antenna ANT4 via switches K1-K4. The electronic device can output a first radio frequency (RF) signal to antenna ANT1 via RF channel 1, a second RF signal to antenna ANT2 via RF channel 2, and a third RF signal to antenna ANT3 via RF channel 3. Both the first and second RF signals contain a first circularly polarized signal, and the third RF signal contains a second circularly polarized signal. The first circularly polarized signal reflects off a sensing object to form a second circularly polarized signal, which is received by the electronic device via antenna ANT4 coupled to RF channel 4. The second circularly polarized signal reflects off a sensing object to form a first circularly polarized signal. Because the polarization of the first circularly polarized signal does not match that of antenna ANT4, it cannot be effectively received. However, due to potential impurities in the polarization of antenna ANT3, the electronic device can also receive a small amount of reflected signal from the sensing object to the third RF signal via antenna ANT4 coupled to RF channel 4. This creates a 3-transmit, 1-receive working mode among the four antennas ANT1-ANT4.

[0080] Furthermore, when an electronic device has N+M antennas and radio frequency channels, all N+M antennas are circularly polarized. When implementing wireless communication, all N+M antennas (ANTs) are simultaneously connected to the transmit or receive links of the N+M radio frequency channels, enabling communication with other electronic devices. When used for sensing functions, the N transmit antennas include at least one antenna with a first polarization, and the M receive antennas include at least one antenna with a second polarization.

[0081] Reference Figures 14-18 As shown, embodiments of this application also provide a circularly polarized antenna (hereinafter referred to as the antenna), which is used in the electronic device provided in the above embodiments. The antenna includes: A first substrate B1 and a second substrate B2 are stacked vertically. The first substrate B1 is horizontally disposed, and the second substrate B2 is perpendicular to the first substrate B1. The first substrate B1 includes a first feed point FP1 disposed on a first side of the first substrate B1 and a first oscillator J1 connected to the first feed point FP1. The second substrate B2 includes a second feed point FP2 disposed on a first side of the second substrate B2 and a second oscillator J2 connected to the second feed point FP2. The second substrate B2 also includes a feed network FN disposed on a first side of the second substrate B2, the feed network FN having an input terminal Pin, a first feed terminal P1, and a second feed terminal P2. The first feed point FP1 is coupled to the first feed terminal P1, and the second feed point FP2 is coupled to the second feed terminal P2; wherein, the first path between the input terminal Pin and the first feed terminal P1 and the second path between the input terminal Pin and the second feed terminal P2 have a predetermined phase difference δθ.

[0082] In this way, the antenna described above can simultaneously excite the first oscillator on the horizontally arranged first substrate B1 and the second oscillator J2 on the vertically arranged second substrate B2 through a feed network PN. Since the feed excitation signal (RF signal) can be input from the same input terminal and transmitted through the first path and the second path respectively to achieve a predetermined phase difference δθ, a circularly polarized signal is finally synthesized on the two oscillators. This antenna sets the feed network and the second oscillator together on a vertical substrate and sets the first oscillator on a horizontal substrate, resulting in a compact structure that is beneficial for the miniaturization of the device.

[0083] Reference Figure 14 , Figure 16 , Figure 17 as well as Figure 18 As shown, the antenna also includes a third substrate B3, wherein the third substrate B3 is disposed on the side of the second substrate B2 away from the first substrate B1, and the second substrate B2 is disposed perpendicular to the third substrate B3; the first substrate B1 also includes a third feed point FP3 disposed on the second side of the first substrate B1 and a third vibrator J3 connected to the third feed point FP3; the second substrate B2 includes a first conductive layer L1 disposed on the second side of the second substrate B2; the third substrate B3 includes a second conductive layer L2 disposed on the third substrate B3, wherein the second conductive layer L2 is used for grounding GND; the third feed point FP3 is coupled to the second conductive layer L2 through the first conductive layer L1.

[0084] Thus, the second conductive layer L2 of the third substrate B3 provides a ground plane (GND) for the antenna. The aforementioned vertical and horizontal properties are relative to the ground plane provided by the third substrate B3. That is, the first substrate B1, as a horizontal substrate, is horizontal to the ground plane provided by the third substrate B3, and the second substrate B2, as a vertical substrate, is perpendicular to the ground plane provided by the third substrate B3.

[0085] For example, refer to Figure 16As shown, the first oscillator J1 includes: at least two first extension arms; each first extension arm includes a first conductive part J1-a and a second conductive part J1-b; wherein, the first end of the first conductive part J1-a is coupled to a first feed point FP1, and the second end of the first conductive part J1-a extends in a radial direction with the first feed point FP1 as the center; the second end of the first conductive part J1-a is connected to the first end of the second conductive part J1-b, the second end of the second conductive part J1-b is a free end, and the second conductive part J1-b extends along an arc with the first feed point FP1 as the center and the first conductive part J1-a as the radius; the second conductive parts J1-b of at least two first extension arms extend in a clockwise direction or in a counterclockwise direction.

[0086] Reference Figure 16 As shown, the third oscillator J3 includes: at least two second arms; each second arm includes a third conductive part J3-a and a fourth conductive part J3-b, wherein the first end of the third conductive part J3-a is coupled to the third feed point FP3, and the second end of the fourth conductive part J3-b extends in a radial direction with the third feed point FP3 as the center; the second end of the third conductive part J3-a is connected to the first end of the fourth conductive part J3-b, the second end of the fourth conductive part J3-b is a free end, and the fourth conductive part J3-b extends along an arc with the third feed point FP3 as the center and the third conductive part J3-a as the radius; the fourth conductive parts J3-b of at least two second arms extend in a counterclockwise direction or in a clockwise direction.

[0087] Continue to refer to Figure 16 As shown, the second oscillator J2 includes at least one monopole connected to the second feed point FP2. Figure 16 The image shows two monopoles, J2a and J2b.

[0088] It should be noted that, in Figure 16 In the example shown, since the first oscillator J1 and the first feed point FP1 are located on the side of the first substrate B1 away from the second substrate B1, when the first feed terminal P1 of the feed network PN is connected to the first feed point FP1, it is necessary to achieve electrical connection through a conductive via penetrating the first substrate B1.

[0089] Thus, when an excitation signal is input to the first oscillator J1 through the feed network PN, a current will be generated on the first extension arm, propagating along the first conductive part J1-a and the second conductive part J1-b (the current direction is as follows). Figure 16 (As shown); when an excitation signal is input to the second oscillator J2 through the feeding network, a current will be formed on the monopole of the second oscillator J2 and propagate along the monopole (the direction of the current is as shown). Figure 16(As shown); thus, the current in the first oscillator J1 mainly propagates in the direction horizontal to the ground, while the current in the second oscillator J2 mainly propagates in the direction perpendicular to the ground, and the two can jointly synthesize a circularly polarized signal. For example, as shown... Figure 16 As shown, when the second conductive portions J1-b of the first extended arm all extend in a clockwise direction, the synthesized circularly polarized signal is a right-hand circularly polarized signal; when the second conductive portions J1-b of the first extended arm all extend in a counterclockwise direction, the synthesized circularly polarized signal is a left-hand circularly polarized signal. Furthermore, referring to… Figure 16 As shown, when an excitation signal is input to the first oscillator J1 through the feed network PN, a current is formed on the second extension arm and propagates along the third conductive part J3-a and the fourth conductive part J3-b (the current direction is as shown). Figure 16 As shown); where, since the second arm of the third oscillator J3 is connected to the ground GND, the current generated along the third conductive part J3-a on the second arm is in the opposite direction to the current generated along the first conductive part J1-a on the first arm; and since the extension direction of the fourth conductive part J3-b of the second arm is opposite to the extension direction of the second conductive part J1-b of the first arm, the current generated by the fourth conductive part J3-b of the second arm is in the same direction as the current generated by the second conductive part J1-b of the first arm (current direction as shown). Figure 16 (As shown). In this way, in the horizontal direction, the electric field generated by the current along the third conductive part J3-a on the second arm can cancel out the electric field formed by the current along the first conductive part J1-a on the first arm; the electric field formed by the current along the fourth conductive part J3-b on the second arm is continuous with the electric field formed by the current along the second conductive part J1-b on the first arm, so that the circularly polarized signal can be synthesized more effectively with the vertical component of the current transmitted on the second oscillator.

[0090] The embodiments of this application do not limit the number of arms of the first oscillator J1 and the third oscillator J3, wherein in Figure 16 In the middle, both the first oscillator J1 and the third oscillator J3 include four arms; Figure 19 In the example shown, both the first oscillator J1 and the third oscillator J3 may include three arms. To ensure that the electric field generated by the current along the third conductive portion J3-a of the second arm can effectively cancel the electric field formed by the current along the first conductive portion J1-a of the first arm, the third conductive portion J3-a of the second arm is aligned vertically with or at least overlaps the first conductive portion J1-a of the first arm. The embodiments of this application do not limit the number of monopoles in the second oscillator J2; for example, refer to… Figure 21 As shown, it is also possible to set only one monopole J2a.

[0091] In addition, refer to Figure 20As shown, the third oscillator J3 includes a ring-shaped fifth conductive part J3-c, which is arranged around and connected to the third feed point FP3. The fifth conductive part J3-c intersects with or covers the first conductive part J1-a of the first arm in the vertical direction. Thus, the fifth conductive part J3-c can effectively shield the electric field formed by the radial current along the first conductive part J1-a on the first arm.

[0092] Of course, in some examples, only the oscillator on one side of the first substrate B1 can be retained as the first oscillator. In this case, as long as the second conductive part J1-b of the first arm is long enough, the electric field formed by the current on the second conductive part J1-b of the two adjacent first arms can be continuously combined with the vertical component of the current transmitted on the second oscillator J2 to form a circularly polarized signal.

[0093] In addition, refer to Figure 16 , Figure 17 as well as Figure 18 As shown, the feed network PN includes: a first impedance adjustment structure Z1 disposed between the input terminal Pin and the first feed terminal P1, and a second impedance adjustment structure Z2 disposed between the input terminal Pin and the second feed terminal P2. The first impedance adjustment structure Z1 and the second impedance adjustment structure Z2 can respectively adjust the phase difference and impedance between the excitation signals introduced into the first oscillator J1 and the second oscillator J2. In some examples, to ensure the bandwidth of the antenna and the effect of the circularly polarized signal, the phase difference δθ can be 90°±α, where α is a sufficiently small error, for example, α less than or equal to 5°. Additionally, in some examples, the first impedance adjustment structure Z1 and / or the second impedance adjustment structure Z2 include a phase shifter. For example, in... Figure 18 The second impedance adjustment structure Z2 shown can be a folded transmission line, the phase difference introduced between the first oscillator J1 and the second oscillator J2 can be adjusted by adjusting the length of the transmission line.

[0094] In some examples, refer to Figure 16 and Figure 18 As shown, the first end of the first conductive layer L1 is connected to the third feed point FP3; the second end of the first conductive layer L1 is connected to the second conductive layer L2. Here, the second end of the first conductive layer L1 and the second conductive layer L2 can be directly connected, for example, by soldering the second end of the first conductive layer L1 to the second conductive layer L2.

[0095] In other examples, to reduce the complexity of the assembly process, such as to eliminate the welding process between the second end of the first conductive layer L1 and the second conductive layer L2, refer to Figure 22 and Figure 23As shown, the first conductive layer L1 includes a connecting portion L11 and a coupling portion L12. The first end of the connecting portion L11 is connected to the third feed point FP3, and the second end of the connecting portion L11 is connected to the coupling portion L12. A gap G exists between the coupling portion L12 and the third substrate B3. Since the radio frequency signal transmitted by the antenna is typically an AC high-frequency signal, utilizing the characteristic of capacitors to pass AC, it is not necessary to solder the first conductive layer L1 to the second conductive layer L2 on the third substrate B3. Instead, a... Figure 22 and Figure 23 The structure shown utilizes the coupling portion L12 and the second conductive layer L2 of the third substrate B3 as the two electrodes of the capacitor, and the gap G between the coupling portion L12 and the third substrate B3 as the dielectric of the capacitor, to achieve coupling between the first conductive layer L1 and the second conductive layer L2. Furthermore, Figure 23 The diagram also shows a cable connected to the input pin of the power supply network PN. The cable core can be soldered to a pad on the second side of the second substrate B2. The pad can be connected to the input pin of the power supply network PN through a via through the second substrate B2. The pad can be disposed in the same layer as the first conductive layer L2 on the second side of the second substrate B2.

[0096] In some examples, refer to Figure 24 Neutral (1) and Figure 24 As shown in (2), the antenna further includes: a first short-circuit stub J1-c disposed on a first side of the first substrate B1; and a second short-circuit stub J3-d disposed on a second side of the first substrate B1; wherein, the first end of the first short-circuit stub J1-c is connected to the first feed point FP1, and the first end of the second short-circuit stub J3-d is connected to the third feed point FP3; the second end of the first short-circuit stub J1-c and the second end of the second short-circuit stub J3-d are connected through a conductive via penetrating the first substrate B1. In this way, the two short-circuit stubs added to the first substrate B1 have high impedance and DC voltage short-circuit characteristics, which can realize the antenna in-situ detection function and determine whether the antenna is working properly; for example, when DC power is directly input to the input terminal Pin of the feed network, if current can be detected on the ground, it indicates that the antenna is in place; otherwise, it indicates that there is an open circuit in the antenna assembly.

Figure 25 (2) provides a left-hand circularly polarized antenna, which can be used for the above purposes. Figure 6 Antennas ANT1 and ANT2 in the middle. Figure 25 The left-hand circularly polarized antenna in (2) is used for the above. Figures 6-8 Antenna ANT1 in the middle, with this Figure 25 The right-hand circularly polarized antenna in (1) is used for the above. Figures 6-8 Simulation of antenna ANT2 yields the following antenna performance parameters. Among them, Figure 26 The voltage standing waveratio (VSWR) of the left circularly polarized antenna provided in the embodiments of this application is shown in the 5-7 GHz range.

Figure 28 The diagram illustrates the azimuth (gain dB) of the left circularly polarized antenna provided in an embodiment of this application in a spherical coordinate system (elevation angle theta ∈ [-180°, 180°], azimuth angle phi = 0°). The antenna performs optimally when VSWR is close to 1, indicating a radiation efficiency greater than 90%. Furthermore, AR < 6dB, resulting in a bandwidth greater than 33%, effectively covering the 5GHz and 6GHz WiFi bands. Within a 3dB beamwidth range at the elevation angle (the abscissa value corresponding to the maximum value -3dB), the primary circular polarization (LHCP) of the left circularly polarized antenna is at least 6dB greater than the cross-polarization (RHCP), indicating that the antenna can achieve relatively pure left-hand circularly polarized wave radiation over a wide elevation angle range.

[0098] Embodiments of this application also provide a communication method applied to the above-mentioned electronic device, the electronic device including: at least two radio frequency channels and at least two antennas; the at least two radio frequency channels include: a first radio frequency channel and a second radio frequency channel; the at least two antennas include: a first antenna and a second antenna; the first radio frequency channel is coupled to the first antenna, and the second radio frequency channel is coupled to the second antenna; wherein, the first antenna and the second antenna are both circularly polarized antennas, and the polarization of the first antenna and the second antenna are different.

[0099] The communication method includes the following steps: S101, in the first mode, the first radio frequency channel outputs a first radio frequency signal through the first antenna, and in the first mode, the second radio frequency channel receives a second radio frequency signal through the second antenna; wherein, the first radio frequency signal includes a first circularly polarized signal, the second radio frequency signal includes a second circularly polarized signal, and the polarization modes of the first circularly polarized signal and the second circularly polarized signal are different.

Therefore, step S101 specifically includes: in the first mode, controlling the first switch to connect the first select terminal and the common terminal of the first switch, and controlling the second switch to connect the second select terminal and the common terminal of the second switch.

[0101] S102, in the second mode, the first radio frequency channel outputs a third radio frequency signal through the first antenna, and in the second mode, the second radio frequency channel outputs a fourth radio frequency signal through the second antenna; wherein the third radio frequency signal includes a third circularly polarized signal, the fourth radio frequency signal includes a fourth circularly polarized signal, and the polarization modes of the third circularly polarized signal and the fourth circularly polarized signal are different.

[0102] In some examples, the first radio frequency channel includes a first transmit link and a first receive link; the second radio frequency channel includes a second transmit link and a second receive link; the electronic device also includes a first switch and a second switch, and step S102 specifically includes: in the second mode, controlling the first switch to connect the first select terminal of the first switch to the common terminal, and controlling the second switch to connect the first select terminal of the second switch to the common terminal.

[0105] The first, second, and third modes mentioned above can be understood as different time periods or operating modes. In different operating modes or time periods, each switch in the electronic device establishes different conduction states between each antenna and the corresponding transmit or receive link in the radio frequency channel, thereby achieving time-division multiplexing of radio frequency signals for wireless communication or simultaneous reception or transmission of radio frequency signals for sensing. Specifically, in some examples, the first mode is switched to the second or third mode based on a first control signal; or, the second or third mode is switched back to the first mode based on a second control signal. This achieves the switching between wireless communication and sensing functions based on the first or second control signal. Furthermore, the electronic device can also switch between the second and third modes, i.e., between the transmit and receive functions of wireless communication. In some examples, the electronic device can configure periodic time slots for each mode. For example, in the uplink time slot, the switch is switched to the state corresponding to the second mode via a control signal; in the downlink time slot, the switch is switched to the state corresponding to the third mode via a control signal; and in the sensing time slot, the switch is switched to the state corresponding to the first mode via a control signal. In addition, in some examples, the switch can be set to the state corresponding to the second or third mode for implementing wireless communication functions by default; when there is a need for sensing, it can be actively switched to the state corresponding to the first mode. For example, when the user activates the ranging or other sensing functions through the APP, the switch is switched to the state corresponding to the first mode in response to the user's operation through the second control signal.
