Problems solved by technology

[0004] Use the connection line of the data interface device as the antenna, which is mainly two-in-one (transmitting data and antenna), and the frequency band of the antenna is low, so it is not suitable for use on mobile phones
In addition, it is inconvenient to carry, and it is not the mainstream trend of mobile phone design at present.
[0005] In the related art, no effective solution has been proposed for the influence of the data interface device on the bandwidth of the antenna

Embodiment 1

[0049] Embodiment 1: An embodiment of an antenna structure.

[0050] Figure 4 is a plan view of the antenna structure according to an embodiment of the present invention, such as Figure 4 As shown, 1 is the PCB of the mobile phone, and 2 is the antenna. The antenna can be three feed points, two feed points or one feed point, which is selected according to the needs of antenna debugging. 3 is a USB connector, of which 31 is the wiring of the USB connector on the PCB, and 32 is the body of the USB connector. The position of the USB connector is not fixed in the antenna area, and it can be under the antenna. 4 is the antenna clearance, and the clearance area is not limited.

[0051] The above-mentioned PCB board 1 is not limited in size and base material, and can also be composed of multiple pieces, such as an antenna sub-board and a main board. The above-mentioned antenna 2 is a normal antenna routing form. There are many types of antenna feed points, which can be in the fo...

Embodiment 2

[0052] Embodiment 2: An embodiment in which the length of the traces of the USB connector is changed to adjust the resonance of the antenna.

[0053] Figure 5 is an antenna structure plan view (1) according to an embodiment of the present invention, such as Figure 5 as shown, Figure 5 is in Figure 4 On the basis of , only adjust the trace length of 31. Wherein, the USB connector body 32 is fully connected to the mobile phone PCB, and the traces of the USB connector 3 on the PCB also need to be ground-shielded and fully connected to the antenna reference ground. By adjusting the length of the USB connector trace 31, the coupling effect with the antenna 2 is enhanced to achieve the purpose of debugging the resonant frequency of the antenna.

[0054] Figure 6 is the original S11 reference graph according to an embodiment of the present invention, Figure 7 It is a reference diagram of S11 after changing the length of the USB connector trace according to the embodiment ...

Abstract

The invention provides an antenna bandwidth debugging processing method and apparatus. An antenna is located in a terminal. The apparatus comprises an antenna body in the terminal, a data interface device arranged in the terminal, and a wire, arranged on a printed circuit board (PCB), of the data interface device. The method includes: debugging the antenna in the terminal so that the bandwidth of the antenna reaches a designated bandwidth range; and debugging the wire of the data interface device of the terminal on the PCB of the terminal so that the bandwidth of the antenna reaches the designated bandwidth in the designated bandwidth range, wherein the data interface device in the terminal and the wire of the data interface device on the PCB are connected with the antenna body in a coupling manner. According to the method and apparatus, the problem of the influence of the data interface device on the bandwidth of the antenna is solved, the influence of the data interface device on the antenna is reduced, and the performance of the antenna is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for debugging and processing the bandwidth of an antenna. Background technique [0002] In the related technology, the data interface device has too much influence on the antenna, mainly on the bandwidth. In order to reduce the influence of the data interface device, or use the data interface device body and the wiring on the circuit as part of the antenna, not only can take into account the appearance Creativity and conception (Ideas, referred to as ID) can also better improve the performance of the antenna. [0003] At present, the data interface device is used as a part of the antenna, mainly using the connecting wire of the external connector as the antenna, which can transmit data and also be used as an antenna, which has the function of two in one. [0004] Use the connection line of the data interface device as the antenna, which is mainly two-in-one...
