Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a radiator and an electronic device. Background Art

[0002] Radiators convert electrical current into outward-radiating electromagnetic waves, enabling wireless communication. The radiator's physical properties (position, shape, material, etc.) determine its radiation direction. Once these physical properties are determined and fixed in the terminal device, the radiator's radiation direction is fixed. When users use terminal devices in different environments, for example, buildings can become obstacles to electromagnetic wave propagation, causing signal strength to attenuate and preventing effective penetration. Blockages by hands and body parts can alter the electromagnetic field distribution around the radiator, distorting or weakening the radiation pattern and affecting the directional transmission of the signal. These factors reduce the quality and stability of signal capture by the receiving device, impacting the user experience. Utility Model Content

[0043] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0045] Example 1

[0046] like Figure 1 and Figure 2 As shown, embodiment 1 of the present application provides a radiator, including:

[0047] A plurality of first radiation branches 1, each at a different location and all electrically connected to the signal transmission interface, for receiving or radiating electromagnetic wave signals;

[0048] a plurality of first switch components 2, each of which has one end electrically connected to the signal transmission interface and the other end electrically connected to one of the first radiation branches 1; the plurality of first switch components 2 being capable of selectively connecting the signal transmission interface and at least one of the first radiation branches 1 based on channel feedback information;

[0049] at least one second radiation branch 3, which is located at a different position from the plurality of first radiation branches 1, and the at least one second radiation branch 3 is electrically connected to the signal transmission interface;

[0050] The first radiation branch 1 and the second radiation branch 3 connected to the signal transmission interface can form a current path to transmit and receive electromagnetic wave signals.

[0051] The first radiating branch 1 can receive electromagnetic wave signals from the outside and transmit them to the signal transmission interface. Simultaneously, the first radiating branch 1 can receive signals from the signal transmission interface and radiate electromagnetic wave signals outward, thus realizing the signal transmission and reception function. Multiple first radiating branches 1 can be arranged at different locations, for example, at different angles or spatial positions, to provide radiation capabilities in multiple different directions to meet different signal transmission requirements.

[0052] The positions of multiple first radiating branches 1 can be reasonably arranged according to actual application requirements. For example, in a mobile device, the first radiating branches 1 can be distributed at different edges or corners of the device to ensure all-round signal coverage. The first radiating branches 1 can be electrically connected to the signal transmission interface through wires, metal traces, conductive traces on a printed circuit board, or feeding points 7. The first radiating branches 1 can be an axisymmetric structure, a curved shape, or other shapes; when the first radiating branches 1 are axisymmetric structures, the first radiating branches 1 can be straight, T-shaped, or branched, etc.

[0053] Multiple first switch assemblies 2 can dynamically switch first radiating branches 1 at different locations to adapt to different channel environments and improve the radiator's adaptability. The number of first switch assemblies 2 can be equal to the number of first radiating branches 1, achieving a one-to-one correspondence between the two. The first switch assemblies 2 can be electrically connected to the first radiating branches 1 via wires, printed circuit board traces, or other methods; the first switch assemblies 2 can also be electrically connected to the signal transmission interface via microstrip traces, printed circuit board traces, or other methods.

[0054] The first switch component 2 can be a switching element with fast switching capabilities and good signal transmission characteristics, such as an electronic switch or radio frequency switch. The first switch component 2 can be configured with a control chip, such as a microprocessor or digital signal processor. The control chip is used to connect to the signal monitoring module or communication control system via wired or wireless signals to obtain channel feedback information, process and analyze it, and control the first switch component 2 to select one or more first radiating branches 1 that can provide the best signal transmission effect and connect them to the signal transmission interface. The channel feedback information may include parameters such as signal strength, signal-to-noise ratio, and multipath fading.

[0055] The second radiating branches 3 form a current path with the first radiating branches 1 and the signal transmission interface. In the transmitting mode, an oscillating current transmitted from the signal transmission interface flows through the two radiating branches, generating a changing electromagnetic field and thereby radiating an electromagnetic wave signal. In the receiving mode, the incident electromagnetic wave induces an oscillating current in the two radiating branches. The oscillating current is transmitted back to the signal transmission interface through the current path, thereby converting the incident electromagnetic wave signal into an electrical signal output, thereby achieving joint transmission and reception of electromagnetic wave signals. The position of the second radiating branches 3 is different from that of the multiple first radiating branches 1 to achieve a multi-directional radiation effect. The second radiating branches 3 can be arranged in a suitable position based on the design requirements and application scenarios of the radiator, for example, at a different angle or spatial position than the first radiating branches 1. The second radiating branches 3 can be electrically connected to the signal transmission interface via a wire, metal trace, conductive trace on a printed circuit board, or a feed point 7. The second radiating branches 3 can have an axisymmetric structure, a curved shape, or other shapes. When the second radiating branches 3 have an axisymmetric structure, the first radiating branches 1 can have a straight shape, a T-shape, or a branch shape, etc. The second radiation branch 3 can be kept in a normally open state to continuously provide stable radiation capability.

[0056] The radiator provided in Example 1 of the present application is provided with a plurality of first radiating branches 1 at different positions, and each first radiating branch 1 is electrically connected to a first switch component 2. The plurality of first switch components 2 can dynamically select the first radiating branch 1 at the appropriate position to operate according to the channel feedback information, thereby realizing dynamic adjustment of the radiation direction, improving the radiator's adaptability to environmental changes, ensuring the signal transmission quality and stability of the radiator, and improving the user experience. In addition, at least one second radiating branch 3 and the plurality of first radiating branches 1 are located at different positions, forming a multi-directional radiation pattern, thereby expanding the signal coverage range; the loop formed by the first radiating branch 1 and the second radiating branch 3 and the signal transmission interface ensures the integrity of the signal and improves the overall signal quality and stability.

[0057] like Figure 1 and Figure 2As shown, in some embodiments, adjacent first radiation branches 1 have a preset angle; and / or, the at least one second radiation branch 3 has a preset angle with the adjacent first radiation branch 1.

[0058] The preset angle value between adjacent first radiating branches 1 can be determined based on the design requirements and application scenarios of the radiator. For example, the preset angle between the brackets of adjacent first radiating branches 1 can be 30°, 45°, 60°, or 90°, etc. The preset angle value between at least one second radiating branch 3 and an adjacent first radiating branch 1 can be determined based on the design requirements and application scenarios of the radiator. For example, the preset angle between the brackets of adjacent first radiating branches 1 can be 30°, 45°, 60°, or 90°, etc.

[0059] When there are multiple second radiating branches 3, adjacent second radiating branches 3 may have a preset angle. The preset angle value between adjacent second radiating branches 3 can be determined based on the design requirements and application scenario of the radiator. For example, the preset angle between adjacent second radiating branches 3 can be 30°, 45°, 60°, or 90°, etc.

[0060] Multiple first radiating branches 1 and second radiating branches 3 can be evenly distributed around the signal transmission interface, and the angles between each radiating branch can be equal. For example, when there are two first radiating branches 1 and two second radiating branches 3, the angles between each radiating branch can be 90 degrees, forming a circular arrangement to improve signal coverage, achieve effective signal propagation in multiple directions, and ensure all-round signal reception and transmission capabilities.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, there are multiple second radiation branches 3, and the multiple second radiation branches 3 are located at different positions and can be connected to the signal transmission interface for receiving or radiating electromagnetic wave signals.

[0062] Multiple second radiating branches 3 are arranged at different positions. For example, multiple second radiating branches 3 can radiate electromagnetic wave signals at different angles or spatial positions, thereby expanding the range of signal coverage. Multiple second radiating branches 3 are used in conjunction with multiple first radiating branches 1 to achieve more comprehensive signal coverage and increase the possibility of signal reception.

[0063] The plurality of second radiation branches 3 can all be kept in a normally open state to continuously provide a stable radiation capability. Figure 1 As shown, in some embodiments, it also includes:

[0064] Multiple second switch components 4, one end of each second switch component 4 is electrically connected to the signal transmission interface, and the other end is electrically connected to one second radiation branch 3, and the multiple second switch components 4 can selectively connect the signal transmission interface with at least one second radiation branch 3 based on the channel feedback information.

[0065] Multiple second switch assemblies 4 enable dynamic switching of second radiating branches 3 at different locations to adapt to different channel environments and improve the radiator's adaptability. The number of second switch assemblies 4 can be equal to the number of second radiating branches 3 to achieve a one-to-one correspondence between the two. The second switch assemblies 4 can be electrically connected to the second radiating branches 3 via wires, printed circuit board traces, or the like; the second switch assemblies 4 can also be electrically connected to the signal transmission interface via microstrip traces, printed circuit board traces, or the like.

[0066] The second switch assembly 4 can be a switch element with fast switching capabilities and good signal transmission characteristics, such as an electronic switch or a radio frequency switch. The second switch assembly 4 can be configured with a control chip, such as a microprocessor or a digital signal processor. The control chip is used to connect to the signal monitoring module or the communication control system via wired or wireless signals to obtain channel feedback information, process and analyze it, and control the second switch assembly 4. The control chip selects one or more second radiating branches 3 that provide the best signal transmission effect for connection to the signal transmission interface, thereby improving the radiator's adaptability and signal transmission quality.

[0067] like Figure 1 As shown, in some embodiments, the number of the first radiation branches 1 and the second radiation branches 3 is the same, and each of the first radiation branches 1 is mirror-symmetrical with one of the second radiation branches 3 .

[0068] The specific number of first radiation branches 1 and second radiation branches 3 can be determined based on the design requirements and application scenarios of the radiator. For example, there can be two, three, or four first radiation branches 1 and second radiation branches 3, etc. Multiple first radiation branches 1 can be adjacent to each other, and multiple second radiation branches 3 can be adjacent to each other. Multiple first radiation branches 1 and multiple second radiation branches 3 can be arranged on opposite sides of a plane. Because the first radiation branches 1 and the second radiation branches 3 are mirror-symmetrical, they can provide uniform radiation capability in multiple directions, significantly improving the radiator's multi-directional radiation capability, signal coverage, and transmission quality.

[0069] When there are two first radiating branches 1 and two second radiating branches 3, the first radiating branches 1 and the second radiating branches 3 are T-shaped, and each first radiating branch 1 is mirrored with a second radiating branch 3, and the angle between adjacent radiating branches is 90 degrees. Take the example of connecting a first radiating branch 1 and a second radiating branch 3 during use: Figures 3 to 5 As shown, a mirror-image first radiating branch 1 and a second radiating branch 3 can be connected to maximize the radiator's directivity at 0° and 180°; alternatively, the radiator can have maximum directivity at 90° and 270°, in which case the current directions of the first transverse branch 11 and the second transverse branch 31 are opposite; the current direction of the first longitudinal branch 12 of the first radiating branch 1, which is perpendicular to the first transverse branch 11, is the same as the current direction of the second longitudinal branch 32 of the second radiating branch 3, which is perpendicular to the second transverse branch 31. Alternatively, an adjacent first radiating branch 1 and a second radiating branch 3 can be connected to maximize the radiator's radiation performance at -45° and 135°.

[0070] like Figures 6 to 8 As shown, when there are two first radiating branches 1 and they are mirror-set, each first radiating branch 1 is T-shaped; there is one second radiating branch 3, and the angles between it and the two first radiating branches 1 are 90°, one first radiating branch 1 can be connected during use to enable the radiator to have maximum radiation performance at -45° and 135°; or, to enable the radiator to have maximum radiation performance at 45° and 225°.

[0071] In some embodiments, further comprising:

[0072] The coaxial line has a first core and a second core; the plurality of the first radiation branches 1 are electrically connected to the signal transmission interface of the first core, and the plurality of the second radiation branches 3 are electrically connected to the signal transmission interface of the second core.

[0073] The first core can be an outer core, and the second core can be an inner core. An insulating layer can be provided between the first core and the second core to prevent signal short circuit; an insulating protective layer can be provided on the outside of the first core to provide additional protection and isolation. A feeding point 7 can be provided at the connection between the multiple first radiating branches 1 and the first core of the coaxial line to ensure that the signal can be effectively transmitted to each first radiating branch 1. A feeding point 7 can be provided at the connection between the multiple second radiating branches 3 and the second core of the coaxial line to ensure that the signal can be effectively transmitted to each second radiating branch 3. The coaxial line can provide good signal transmission performance and reduce signal attenuation and interference. Connecting the first radiating branch 1 and the second radiating branch 3 to different cores of the coaxial line respectively can physically isolate the signals of the two groups of radiating branches, reduce signal interference, and improve signal purity and stability.

[0074] like Figure 1 and Figure 2 As shown, in some embodiments, it also includes:

[0075] A first main branch 5 is electrically connected to the signal transmission interface; one end of each first switch component 2 is connected to the first main branch 5, and the other end is electrically connected to one of the first radiation branches 1; the multiple first switch components 2 can selectively connect the first main branch 5 with at least one of the first radiation branches 1 based on the channel feedback information; and / or,

[0076] The second main branch 6 is electrically connected to the signal transmission interface; one end of each second switch component 4 is connected to the second main branch 6, and the other end is electrically connected to one second radiation branch 3; the multiple second switch components 4 can selectively connect the second main branch 6 with at least one second radiation branch 3 based on the channel feedback information.

[0077] The shape of the first main branch 5 can be specifically designed according to the position and number of the multiple first switch components 2. For example, when there are two first switch components 2 and they are at a 90° angle, the first main branch 5 can be L-shaped. The first main branch 5 can be electrically connected to the signal transmission interface through a wire or a feeding point 7. The first main branch 5 serves as a relay point for signal transmission and can distribute the signal of the signal transmission interface to multiple first radiating branches 1, facilitating centralized management and control of the signal, while simplifying the wiring and connection of the first switch component 2.

[0078] The shape of the second main branch 6 can be specifically designed according to the positions of the multiple second switch components 4. For example, when there are two second switch components 4 and they are at a 90° angle, the second main branch 6 can be L-shaped. The first main branch 5 can be electrically connected to the signal transmission interface through a wire or a feeding point 7. The second main branch 6 serves as a relay point for signal transmission and can distribute the signal of the signal transmission interface to the multiple second radiating branches 3, facilitating centralized management and control of the signal while simplifying the wiring and connection of the second switch components 4.

[0079] The first main branch 5 and the second main branch 6 can be set either individually or in combination.

[0080] In some embodiments, a control module is signal-connected to the plurality of first switch components 2 , and the control module is configured to receive the channel feedback information and control the opening of at least one of the first switch components 2 based on the channel feedback information.

[0081] The control module can connect to multiple first switch assemblies 2 via wired signals (e.g., wires or a data bus) or wireless signals (e.g., Bluetooth or wireless networks). The control module receives channel feedback information from the signal monitoring module or communication control system, processes and analyzes the received channel feedback information, generates corresponding control signals based on the processing and analysis results, and then transmits the control signals to the first switch assemblies 2 via a wired or wireless interface. The control module can be implemented using a microcontroller or digital signal processor. By providing a centralized control module to manage multiple first switch assemblies 2, the radiator structure can be simplified, hardware costs can be reduced, and reliability can be improved.

[0082] When there are multiple second switch components 4, the control module can be connected to the multiple second switch components 4 through wired signals (such as wires or data buses, etc.) or wireless signals (such as Bluetooth or wireless networks, etc.) to simplify the structure of the radiator.

The first radiating branches 1 are distributed along the first and third sides, forming a mirror-symmetrical layout to achieve multi-directional radiation capability. The second radiating branches 3 are distributed along the second and fourth sides, forming a mirror-symmetrical layout to achieve multi-directional radiation capability.
