[0038] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is apparent to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application, some technical features well known in the art are not described.

[0039] It should be understood that the present application can be implemented in different forms and should not be construed as being limited to the embodiments presented herein. On the contrary, providing these embodiments will make the disclosure thorough and complete and fully convey the scope of the present application to those skilled in the art. In the accompanying drawings, the sizes and relative sizes of layers and regions may be exaggerated for clarity. The same reference numerals throughout represent the same elements.

[0040] It should be understood that when an element or layer is referred to as "on ...", "adjacent to ...", "connected to" or "coupled to" other elements or layers, it can be directly on, adjacent to, connected to or coupled to other elements or layers, or there can be intervening elements or layers. On the contrary, when an element is referred to as "directly on ...", "directly adjacent to ...", "directly connected to" or "directly coupled to" other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc. can be used to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, without departing from the teachings of the present application, the first element, component, region, layer or part discussed below can be represented as a second element, component, region, layer or part.

[0041] Spatially relative terms such as "under," "below," "below," "under," "above," "above," etc., may be used herein for ease of description to describe the relationship of an element or feature shown in the figures to other elements or features. It should be understood that in addition to the orientations shown in the figures, the spatially relative terms are intended to include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, then the elements or features described as "under other elements" or "under" or "under" will be oriented as "on" the other elements or features. Therefore, the exemplary terms "under" and "under" may include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or other orientations) and the spatial descriptors used herein are interpreted accordingly.

[0042] In the related art, increasing the distance between two antennas in an antenna assembly can reduce the coupling strength between the antenna elements, but this will cause the size of the entire antenna assembly to be too large and fail to achieve the purpose of miniaturization.

[0043] When the size of the antenna assembly is reduced, since the two antennas in the antenna assembly have the same operating frequency, when the two antennas are placed in close positions, the radiation pattern beams of the two antennas will form an interference area, resulting in enhanced coupling between the two antennas, causing the isolation to be too low, thereby affecting the performance of the antenna assembly.

[0044] In order to solve at least one of the above problems, the present application provides an antenna assembly, including: a substrate; an antenna, arranged on the substrate, for receiving and transmitting radio frequency signals; the antenna includes: a first branch and a second branch connected to each other, the first branch is suitable for forming a first groove by bending, and the second branch is at least partially arranged in the first groove.

[0045] According to the antenna assembly of the present application, the antenna includes a first branch and a second branch connected to each other, the first branch is suitable for forming a first groove by bending, and the second branch is at least partially arranged in the first groove, so that the total length of the antenna can be increased through the first groove to change the path of the current in the antenna, and at the same time change the propagation direction of the main beam of the antenna, so that the propagation direction of the main beam of the antenna is directed from the inside of the substrate to the outside of the end of the substrate, thereby reducing the radiation level value intensity of the antenna in the radiation interference area, reducing the mutual interference between multiple antennas, achieving the effect of increasing isolation, and improving the performance of the antenna assembly.

[0046] In order to thoroughly understand the present application, a detailed structure will be presented in the following description to illustrate the technical solution proposed by the present application. The preferred embodiments of the present application are described in detail as follows, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0048] Based on this, the present application provides an antenna assembly 100 capable of increasing antenna isolation. According to the antenna assembly 100 of the present application, the antenna includes a first branch 1211 and a second branch 1212 connected to each other, a first groove 1213 is provided in the first branch 1211, the first branch 1211 is suitable for forming the first groove 1213 by bending, and the second branch 1212 is at least partially provided in the first groove 1213, so that the total length of the antenna can be increased through the first groove 1213 to change the path of the current in the antenna, and at the same time change the propagation direction of the main beam of the antenna, so that the propagation direction of the main beam of the antenna is directed from the inside of the substrate 110 to the outside of the end of the substrate 110, thereby reducing the radiation level value intensity of the antenna in the radiation interference area, reducing the mutual interference between multiple antennas, achieving the effect of increasing isolation, and improving the performance of the antenna assembly 100.

[0049] In some embodiments, the antenna is a WIFI or Bluetooth antenna.

Alternatively, the antenna can also be a WIFI and Bluetooth two-in-one antenna, which can receive and transmit WiFi radio frequency signals and Bluetooth radio frequency signals, realizing the synthesis and miniaturization design of the antenna.

[0050] In some embodiments, Figure 1 As shown, the second branch 1212 is adapted to be bent to form a second groove 1214 , and the second groove 1214 is at least partially located in the first groove 1213 .

[0051] The second groove 1214 may be completely located in the first groove 1213, or only partially located in the first groove 1213, which is not limited. Figure 1 , which is a schematic diagram showing that only a portion of the second groove 1214 is located within the first groove 1213 .

[0052] In this embodiment, the second branch is bent to form a second groove, so that the total length of the antenna can be further increased through the second groove to change the path of the current in the antenna and simultaneously change the propagation direction of the main beam of the antenna, so that the propagation direction of the main beam of the antenna is directed from the inside of the substrate 110 to the outside of the end of the substrate 110, thereby reducing the intensity of the radiation level value of the antenna in the radiation interference area, reducing mutual interference between multiple antennas, achieving the effect of increasing isolation, and improving the performance of the antenna assembly 100.

[0053] In some embodiments, Figure 1As shown, the opening directions of the first groove 1213 and the second groove 1214 are consistent. In this embodiment, by making the opening directions of the first groove 1213 and the second groove 1214 consistent, the directions of the beams generated by the first branch 1211 and the second branch 1212 can be as consistent as possible, thereby further avoiding signal interference and improving signal strength.

[0054] In some embodiments, the first branch 1211 is substantially U-shaped. By configuring the first branch 1211 to be U-shaped, a first groove 1213 is formed inside the U-shape.

[0055] In some embodiments, the second branch 1212 is substantially U-shaped. By configuring the second branch 1212 to be U-shaped, a second groove 1214 is formed inside the U-shape.

[0056] In some embodiments, Figure 1 As shown, the first groove 1213 is a U-shaped groove, and the second groove 1214 is a strip groove. Of course, the present application does not limit the first groove 1213 and the second groove 1214, and they can also be configured in other suitable shapes.

[0060] Specifically, the substrate 110 is provided with an RF connector mounting hole, and the RF connector is mounted on the substrate through the RF connector mounting hole. The transmission line can be selected as a 50Ω microstrip line, and the RF connector is connected to the antenna through the 50Ω microstrip line. The RF signal received by the antenna can be transmitted to the RF connector through the 50Ω microstrip line. The RF connector can also be connected to the communication device through the coaxial cable, and the RF connector can then transmit the RF signal received by the antenna to the communication device.

[0061] The 50Ω microstrip line may preferably be of the type of “CPWG (Coplanar waveguide, coplanar stripline or also called coplanar microstrip line)” to reduce antenna transmission loss and increase anti-interference capability.

[0062] In some embodiments, the antenna assembly 100 further includes: a detector, disposed on a circuit between the antenna and the RF connector, for detecting whether the RF connector is connected to a communication device.

[0063] The detector may be a resistor, a sensor or other suitable electronic components, which are not limited. Taking the detector as a resistor as an example, the resistor can be used for direct current conduction to detect whether the RF connector is connected to the communication device.

[0064] In some embodiments, the substrate 110 has a first surface and a second surface relative to each other, and the antenna assembly 100 further includes: a first ground terminal and a second ground terminal, the first ground terminal is arranged on the first surface, the second ground terminal is arranged on the second surface, the first ground terminal is connected to the antenna, a metallized hole is arranged on the substrate 110, and the second ground terminal is connected to the first ground terminal through the metallized hole.

[0066] The first surface may be referred to as the front surface of the substrate 110, and the second surface may be referred to as the back surface of the substrate 110. The antenna may be disposed on the first surface of the substrate 110, and the antenna is connected to a first ground terminal, and the first ground terminal is further connected to a second ground terminal located on the second surface of the substrate 110 through a metallized hole to achieve antenna grounding.

[0067] In some embodiments, Figure 1 As shown, the antenna assembly 100 further includes: an auxiliary detector, which is disposed on the circuit between the antenna and the first ground terminal to assist in detecting whether a communication device is connected.

[0068] The auxiliary detector may be a capacitor, etc., which is not limited. The capacitor can pass high frequencies and block direct currents, so as to assist the detector in detecting whether a communication device is connected when the detector is a resistor.

[0069] In some embodiments, the antenna assembly 100 further includes a housing, and the substrate 110 may be disposed in the housing.

The substrate 110 has a first end and a second end opposite to each other. The first antenna 121 is provided at the first end, and the second antenna 122 is provided at the second end.

[0072] In this embodiment, the substrate 110 may have a long side and a short side, and the first antenna 121 and the second antenna 122 may be arranged at both ends of the long side of the substrate 110, or at both ends of the short side of the substrate 110, without limitation. By arranging the first antenna 121 and the second antenna 122 at both ends of the substrate 110, the distance between the first antenna 121 and the second antenna 122 may be increased, so as to increase the isolation. Therefore, it can be understood that in order to increase the isolation as much as possible, the first antenna 121 and the second antenna 122 are preferably arranged at both ends of the long side of the substrate 110.

[0073] For ease of understanding, the structure of the antenna assembly 100 is described in more detail below by taking a plurality of antennas including a first antenna 121 and a second antenna 122 as an example.

By combining the vehicle-mounted WiFi and Bluetooth antennas into two-in-one, a synthetic and miniaturized design is achieved.

The second RF connector can also be connected to the communication device through the coaxial cable, and the second RF connector can then transmit the RF signal received by the second antenna 122 to the communication device.

[0079] In this embodiment, by providing the first RF connector and the second RF connector, either a single-channel output or a dual-channel output can be formed.

[0080] In some embodiments, Figure 1As shown, the antenna assembly 100 also includes: a first detector 151, which is arranged on the circuit between the first antenna 121 and the first RF connector, and is used to detect whether the first RF connector is connected to the communication device; a second detector 152, which is arranged on the circuit between the second antenna 122 and the second RF connector, and is used to detect whether the second RF connector is connected to the communication device.

[0081] The detector may be a resistor, a sensor or other suitable electronic components, which is not limited. Taking the detector as a resistor as an example, the first detector 151 may be called a first resistor, and the second detector 152 may be called a second resistor. The first resistor may be used for direct current conduction to detect whether the first RF connector is connected to the communication device; the second resistor may be used for direct current conduction to detect whether the second RF connector is connected to the communication device. Through the first resistor and the second resistor, it is possible to detect whether the antenna assembly 100 is connected to the communication device.

[0082] In some embodiments, Figure 1 and Figure 2 As shown, the substrate 110 has a first surface and a second surface relative to each other, and the antenna assembly 100 also includes: a first grounding terminal 161 and a second grounding terminal 162, the first grounding terminal 161 is arranged on the first surface, the second grounding terminal 162 is arranged on the second surface, the first grounding terminal 161 is connected to the first antenna 121, and a first metallized hole 171 is arranged on the substrate 110, and the second grounding terminal 162 is connected to the first grounding terminal 161 through the first metallized hole 171; a third grounding terminal 163 and a fourth grounding terminal 164, the third grounding terminal 163 is arranged on the first surface, the fourth grounding terminal 164 is arranged on the second surface, the third grounding terminal 163 is connected to the second antenna 122, and a second metallized hole 172 is arranged on the substrate 110, and the fourth grounding terminal 164 is connected to the third grounding terminal 163 through the second metallized hole 172.

[0083] Figure 1 1 shows a first surface of the substrate 110 , which may be referred to as a front surface of the substrate 110 ; Figure 2 The second surface of the substrate 110 is shown, and the second surface can be referred to as the back side of the substrate 110.
