[0002] Antennas in electronic devices are typically fixed, and the radiation patterns of multiple antennas cannot be changed. The directivity coefficient of the composite radiation pattern needs to be as small as possible to meet the requirements of everyday omnidirectional communication. However, electronic devices sometimes operate in directional communication scenarios, such as emergency communication scenarios. When the signal in the electronic device's radiation pattern is weaker at an angle towards the network device, communication quality will be degraded. Currently, solutions to improve communication quality in directional communication scenarios for electronic devices are costly. Summary of the Invention

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0022] First, the application scenarios involved in the embodiments of this application will be introduced.

[0023] Communication system

[0024] Figure 1 This is a schematic diagram of a wireless communication system applied in an embodiment of this application. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 may provide communication coverage for a specific geographical area and may communicate with the terminal device 120 located within that coverage area.

[0025] For example, Figure 1 The illustration shows a network device and two terminals. Optionally, the wireless communication system 100 may include multiple network devices and each network device may include other number of terminal devices within its coverage area. This application embodiment does not limit this.

[0026] It should be understood that the technical solutions of the embodiments of this application can be applied to various communication systems, such as: Global System for Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WIMA) communication system, 5th Generation (5G) system, or New Radio (NR), etc. The technical solutions provided in this application can also be applied to future communication systems, such as 6th Generation mobile communication systems, satellite communication systems, etc.

[0027] The terminal device in this application embodiment can also be referred to as a terminal, user equipment (UE), user terminal, access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote terminal, remote station, mobile device, wireless communication device, user agent, or user apparatus. The terminal device in this application embodiment can be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects, and machines, such as a handheld device with wireless connectivity, vehicle-mounted device, etc. The terminal devices in the embodiments of this application can be mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, self-driving, remote medical surgery, smart grids, transportation safety, smart cities, and smart homes, etc. Optionally, the UE can act as a base station. For example, the UE can act as a scheduling entity, providing sidelink signals between UEs in V2X or D2D, etc. For example, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0028] The network device in this application embodiment can be a device for communicating with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network. A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master MeNB, auxiliary SeNB, multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar, or a combination thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. Base stations can also be mobile switching centers, devices that perform base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, network-side devices in 6G networks, and devices that perform base station functions in future communication systems. Base stations can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment.

[0029] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0030] In some deployments, the network device in this application embodiment may refer to a CU or a DU, or the network device may include both a CU and a DU. The gNB may also include an AAU.

[0031] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0032] Network devices can provide services to a cell. Terminal devices communicate with the network devices through the transmission resources corresponding to that cell. The cell is the cell corresponding to the network device. A cell can belong to a macro base station or to a base station corresponding to a small cell.

[0033] In most scenarios, signals are emitted by base stations and, after multiple diffractions, arrive from all directions, making it mostly an omnidirectional communication scenario. Taking a mobile phone as an example, current mobile phones typically have two transmitting antennas for signal transmission. To adapt to omnidirectional communication scenarios, the directions of these two transmitting antennas... Figure 1 They are generally in a complementary state. Figure 2 This is a schematic diagram of the antenna pattern of a mobile phone. (For example...) Figure 2 As shown, mobile phone 220 can communicate with multiple network devices 210. Mobile phone 220 may include a first antenna 221 and a second antenna 222. The directions of the first antenna 221 and the second antenna 222 are shown. Figure 1 They are typically in a complementary configuration, used to receive signals from all directions. Antennas in electronic devices are usually fixed, and the radiation patterns of the two antennas cannot be changed. The directivity coefficient of the combined radiation pattern needs to be as small as possible to meet the requirements of everyday omnidirectional communication.

[0034] However, terminal devices sometimes operate in directional communication scenarios, such as emergency communication scenarios where regular base stations are damaged or affected. Alternatively, under certain extreme conditions, base stations in remote areas may only transmit signals in one direction. That is, the base station's signal only exists in one direction, and the antenna does not need to receive signals from other directions. Since the antenna pattern in electronic devices is usually fixed, when the weaker angle of the electronic device's pattern is directed towards the network device for communication, it leads to a decrease in communication quality. Currently, the following methods are mainly used to improve emergency communication quality:

[0035] (i) Low Earth Orbit (LEO) satellite communication is conducted using a non-terrestrial network (NTN). This primarily involves bidirectional communication with satellites via the N255 frequency band.

[0036] Compared to traditional terrestrial networks, non-terrestrial networks typically utilize satellites and high-altitude platforms (HAPs) for deployment. Network devices in an NTN system can communicate with terminal devices via satellite, or the network devices themselves can be satellites.

[0037] (ii) Use high-performance radio frequency chips. For example, the Honor C1 radio frequency chip can enhance antenna transmission power and improve connection stability, with a maximum improvement of about 4dB, but the cost is relatively high.

[0038] In the above methods, NTN low-Earth orbit satellite communication is based on the N255 frequency band, which is close to the GPS frequency band (1176-1575MHz). Both bands need to operate simultaneously, therefore a single antenna cannot be used. If separate antennas are used, the antenna architecture needs to be redesigned and the corresponding length allocated, which is a significant challenge given the limited space inside mobile phones. Adding an extra antenna also increases costs. In summary, current solutions for improving communication quality in emergency communication scenarios suffer from high costs or complex deployment issues.

[0039] It should be noted that the poor communication quality of omnidirectional communication terminal devices in emergency scenarios mentioned above is only an example. The embodiments of this application can be applied to any type of scenario where the communication quality of omnidirectional communication terminal devices is poor in directional communication scenarios.

[0040] Therefore, how to develop a solution to improve the communication quality of omnidirectional communication terminal devices under directional communication is a problem that needs to be solved.

[0041] Based on this, this application proposes an antenna device. This application proposes to superimpose the radiation patterns of strong points in the antenna device's radiation pattern, thereby achieving signal enhancement when receiving signals from a certain direction. Figure 3 This is a schematic diagram of the antenna device provided in an embodiment of this application. The following is in conjunction with… Figure 3 The antenna device according to the embodiments of this application will be described in detail. For example... Figure 3 As shown, the antenna device 300 may include: a feed 310, a first radiating element 320, and a second radiating element 330.

[0042] The feed source 310, also known as a power supply unit, is used to feed signals to the radiating unit for transmission or to receive signals received by the radiating unit. The feed source 310 is configured to generate excitation signals, such as cellular excitation signals, WiFi excitation signals, Bluetooth excitation signals, etc.

[0043] The first radiating element 320 is connected to the feed source 310 and is used to receive and / or transmit wireless signals. The first radiating element is also referred to as the first radiator.

[0044] The second radiating unit 330 is connected to the feed source 310 via a direction adjustment unit and is used to receive and / or transmit wireless signals.

[0045] The direction adjustment unit is used to adjust the radiation pattern of the second radiation unit 330 to improve the directivity coefficient of the composite radiation pattern of the antenna device 300. The composite radiation pattern is the radiation pattern jointly formed by the first radiation unit 320 and the second radiation unit 330.

[0046] An antenna radiation pattern, also known as a far-field pattern, is a graphical representation of the relative field strength (normalized modulus) of the radiated field at a certain distance from the antenna, showing how this varies with direction. It is typically represented by two mutually perpendicular plane radiation patterns passing through the antenna's maximum radiation direction. The antenna radiation pattern is used to represent the directivity of an antenna; "antenna directivity" refers to the relationship between the relative value of the antenna's radiated field and its spatial direction at the same distance in the far field. Antenna radiation patterns can be divided into horizontal plane radiation patterns and vertical plane radiation patterns.

[0047] The directivity coefficient refers to the ratio of the radiated power density (or field strength square) of a certain antenna (radiating element) to the radiated power density (or field strength square) of an omnidirectional antenna (point source) under the same distance and radiation conditions. It is usually represented by D.

[0048] In directional communication scenarios, such as certain emergency or extreme scenarios, the base station may only exist in one direction. In this case, the radiation pattern of the second radiation unit 330 can be adjusted by the direction adjustment unit to make it coincide with the radiation pattern of the first radiation unit 320. This can improve the directivity coefficient of the composite radiation pattern, thereby improving directivity and gain, and ultimately enhancing communication quality.

[0049] In some implementations, the orientation adjustment unit can be a phase shifter. The phase shifter is used to change the phase of the excitation signal fed into the second radiation unit 330 to adjust the radiation pattern of the second radiation unit 330.

[0050] A phase shifter is a device that can adjust the phase of a signal wave. By adjusting the signal phase of the phase shifter, the beamforming of an antenna can be improved, the sidelobes and gain of the antenna can be optimized, and the radiation pattern of the communication signal radiated by electronic devices can be changed through the beamforming mechanism.

[0051] Antenna device 300 typically operates in omnidirectional communication scenarios. In some implementations, when antenna device 300 is used for omnidirectional communication, the phase shifter can be turned off, or the phase shifter can be used to reduce the directivity coefficient of the synthesized radiation pattern to make it suitable for omnidirectional communication.

[0052] With increasing emphasis on personal health and safety, people are paying more attention to the radiation emitted by end products, and the requirements for the specific absorption rate (SAR) value of these products are becoming increasingly stringent. The SAR value is directly proportional to the radiated power of the end product; the higher the radiated power, the higher the SAR. Antenna device 300 typically operates in SAR backoff mode, controlling the total radiated power to ensure a reasonable SAR value. In some implementations, such as in emergency communication scenarios, antenna device 300 can briefly exit SAR backoff mode to increase the total radiated power and improve communication quality.

[0053] In some implementations, the antenna device 300 may include multiple radiating elements. The second radiating element 330 may be any of the multiple radiating elements other than the first radiating element 330. By changing the phase of the excitation signal fed to the second radiating element 330 through a phase shifter, the radiation pattern of the second radiating element 330 is adjusted, thereby improving the directivity coefficient of the composite radiation pattern of the antenna device.

[0054] This application embodiment, without altering the existing antenna architecture, controls the radiation pattern of one radiating element by adding a direction adjustment unit, superimposing the strong points of the synthesized radiation pattern to improve the directivity coefficient of the synthesized radiation pattern. This application embodiment does not change the original antenna architecture and has low cost. In directional communication, this application embodiment only receives signals from one direction, which helps improve directivity and antenna gain, increases uplink transmission power, and thus improves communication quality, enabling directional communication functions such as emergency communication.

[0055] The embodiments of this application will be further described below with reference to some possible implementations.

[0056] Figure 4 yes Figure 3 A schematic diagram of one possible implementation of the antenna device. (See diagram for example.) Figure 4 As shown, the antenna device 400 may include: a feed 410, a first radiating element 420, and a second radiating element 430.

[0057] The feed source 410 is used to feed signals to the radiating element for transmission, or to receive signals received by the radiating element.

[0058] The first radiating element 420 is connected to the feed 410 and is used to receive and / or transmit wireless signals.

[0059] The second radiating unit 430 is connected to the feed source 410 via a phase shifter 431 and is used to receive and / or transmit wireless signals.

[0060] The phase shifter 431 is used to change the phase of the excitation signal fed into the second radiating element 430 to adjust the radiation pattern of the second radiating element 430, improve the beamforming of the antenna device, and thereby improve the directivity coefficient of the composite radiation pattern of the antenna device 400.

[0061] Figure 5a yes Figure 4 A schematic diagram of a possible implementation of a radiating unit. Figure 5a The radiating element 500 can be either a first radiating element 420 or a second radiating element 430. The radiating element 500 is an ideal antenna for the B3 band (1710–1880 MHz), with a left-handed antenna structure and a resonant frequency of 1.84 GHz. Figure 5a As shown, the radiating element 500 may include a radiating stub 510 and a feed point 520. For example, the specific length A of the radiating stub 510 may be 19.80 mm, and the length B from the end point of the radiating stub 510 to the feed point 520 may be 4.00 mm. Figure 5b This is a schematic diagram of a possible LC filter matching circuit for a 5a radiating element. Figure 5b As shown, capacitor C1 can be 0.4 picofarads (pF), and inductor can be the parasitic inductance of the radiating stub 510. One end of capacitor C1 is connected to the mobile phone body 530 (such as the baseband chip end).

[0062] Figure 6 This is a schematic diagram illustrating the performance parameters of the radiating element in 5a. For example... Figure 6 As shown, the solid black line curve represents the return loss coefficient S11, the dashed line curve represents the system radiation efficiency, and the dashed line curve represents the system overall efficiency. It can be seen that the system overall efficiency is highest at a frequency f = 1.84 GHz, at -1.6702 dB. Figure 7 This is a schematic diagram of the radiation pattern of a 5a radiating element. For example... Figure 7 As shown, the directivity coefficient D of the radiating element 500 is 2.283 dBi, the system radiation efficiency is -1.515 dB, and the overall system efficiency is -1.67 dB. Figure 7 The darker the grayscale, the greater the antenna gain; the lighter the grayscale, the smaller the gain.

[0063] Figure 8 yes Figure 4 A schematic diagram of a communication scenario using an antenna device. (Example) Figure 8 As shown, the communication system includes only one base station 810. The terminal device can be a mobile phone, and the terminal device 820 can be configured with... Figure 4The antenna device 400 shown has two radiating elements, or in other words, a first radiating element and a second radiating element. Therefore, for the terminal device 820, the signal transmitted by the base station 810 exists only in one direction, and the antenna device of the terminal device 820 does not need to receive signals from other directions. When the terminal device 820 communicates with the base station 810, the antenna pattern of the terminal device 820 can be adjusted to be aligned with the direction of the base station 810.

[0064] Figures 9a-9d yes Figure 4 A schematic diagram of the composite radiation pattern of the antenna device, wherein the first radiating element 420 and the second radiating element 430 of the antenna device 400 adopt a Figure 5a The radiating unit structure shown has both the first radiating unit 420 and the second radiating unit 430 having Figure 6 and Figure 7 The directional coefficient and other properties are shown. For illustrative purposes, Figures 9a-9d Radiation unit 1 is the first radiation unit 420, and radiation unit 2 is the first radiation unit 430. For example... Figure 9a As shown, by changing the phase of the excitation signal fed to the second radiating element 430 by the phase shifter, the angle of the radiation pattern of the second radiating element 430 is adjusted to 0 degrees, that is, the radiation patterns of the first radiating element 420 and the second radiating element 430 are at their initial positions and opposite in direction. At this time, the directivity coefficient D of the combined radiation pattern of the first radiating element 420 and the second radiating element 430 is 2.922 dBi, the system radiation efficiency is -1.705 dB, and the overall system efficiency is -11.78 dB. For example, as... Figure 9b As shown, the radiation pattern angle of the second radiating element 430 is adjusted to 90 degrees by changing the phase of the phase shifter. At this time, the directivity coefficient D of the combined radiation pattern of the first radiating element 420 and the second radiating element 430 is 3.361 dBi. Figure 9c As shown, by changing the phase of the phase shifter, the angle of the radiation pattern of the second radiating element 430 is adjusted to 180 degrees, meaning the directions of the radiation patterns of the first radiating element 420 and the second radiating element 430 are the same. At this time, the directivity coefficient D of the combined radiation pattern of the first radiating element 420 and the second radiating element 430 is 3.986 dBi. Figure 9d As shown, the radiation pattern angle of the second radiating element 430 is adjusted to 270 degrees by changing the phase of the phase shifter. At this time, the directivity coefficient D of the combined radiation pattern of the first radiating element 420 and the second radiating element 430 is 3.797 dBi.

[0065] As can be seen, the maximum directivity coefficient D can be 3.986 dBi, which is about 1.7 dBi greater than the directivity coefficient of a single radiating element (2.283 dBi). The directivity coefficient of two radiating elements with the same radiation pattern can be about 1.1 dB greater than that of two elements with opposite directions (3.986 - 2.922 = 1.064). The actual increase in the directivity coefficient of an antenna device is usually related to the original radiation pattern. Theoretically, the directivity coefficient can increase by a maximum of 3 dB.

[0066] This application uses a phase shifter to adjust the radiation pattern of one radiating element, increasing the directivity coefficient of the combined radiation pattern of the two radiating elements and concentrating energy in a certain direction, suitable for directional communication such as outdoor emergency situations. In some embodiments, software can be used to instruct the user to align the enhanced direction of the antenna radiation pattern with the direction of the base station, thereby improving antenna performance and achieving directional communication under certain extreme conditions.

[0067] When the antenna device 400 is operating in a typical omnidirectional communication scenario, the phase shifter 431 can be turned off, or the phase shifter 431 can be used to reduce the directivity coefficient of the composite pattern to make it suitable for omnidirectional communication.

[0068] In omnidirectional communication scenarios, antenna device 400 typically operates in specific absorptivity backoff mode, controlling the total radiated power to ensure SAR value compliance. For example, in directional communication scenarios for emergency communication, antenna device 400 can exit specific absorptivity backoff mode for a short period to increase the total radiated power of the two radiating elements and improve communication quality.

[0069] This application embodiment, without changing the existing antenna architecture, improves the directivity coefficient of the synthesized radiation pattern by adding a phase shifter to control the radiation pattern of one radiating element and superimposing the strong points of the synthesized radiation pattern. This application embodiment does not change the original antenna architecture and has low cost. In directional communication, this application embodiment only receives signals from one direction, which helps improve directivity and antenna gain, increases uplink transmit power, and thus enhances communication quality.

The composite radiation pattern is formed jointly by the first and second radiating elements.

[0074] Optionally, the direction adjustment unit is a phase shifter. The phase shifter changes the phase of the excitation signal fed into the second radiation element to adjust the radiation pattern of the second radiation element.
