Problems solved by technology

[0004] 1) In order to ensure the efficiency of the antenna, it is generally required that the height of the bracket or the distance between the antenna wiring and the main board be more than 6mm, which will have an adverse effect on the height of the entire terminal, resulting in a thicker terminal, affecting the appearance, and poor user experience
Therefore, the height of the single-sided support of the terminal often cannot meet the requirements of the antenna efficiency for the height of the support.
[0005] 2) For some terminals that support lower frequency bands, since only the upper surface and side surface of the bracket, or one side surface of the structural member are used, the wiring area and antenna height cannot meet the actual requirements, thus increasing the debugging Difficulty; in addition, low-frequency performance may also become poor due to trace area and height constraints

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] figure 1 is a schematic diagram of the antenna structure of a data card terminal, such as figure 1 As shown, the diversity antenna 1 is close to the USB head 4 of the data card, the main antenna 2 is far away from the USB head of the data card, and the Wifi antenna 5 is located on the left side of the main board 3; wherein, the main antenna 2 and the diversity antenna 1 both adopt the traditional Single-sided bracket form.

[0034] figure 2 It is a schematic diagram of the antenna structure of a mobile phone terminal. Such as figure 2 As shown, the antenna structure includes a diversity antenna 1 , a main antenna 2 , a Wifi antenna 5 , a GPS positioning antenna 6 , and a Bluetooth antenna 7 . Since the antenna structure of the mobile phone terminal mainly considers the space of the main antenna 2, the diversity antenna 1...

Abstract

The invention provides an antenna structure, including more than one antenna spring, an antenna feed spring, and antenna lines positioned at two sides of a main board. The antenna feed spring and each antenna spring are fixed on the main board and are contacted with the antenna lines. The antenna feed spring and at least one antenna spring are positioned in antenna clearance zones at the two sides of the main board respectively and are electrically connected with a main board line by through holes of the main board, so as to connect the antenna lines positioned at the two sides of the main board.

Description

technical field [0001] The present invention relates to antenna technology in the field of mobile communication, in particular to an antenna structure. Background technique [0002] At present, the antenna of the terminal will adopt the form of a single-sided bracket, that is, the ordinary bracket is directly assembled on one side of the motherboard, so that the antenna wiring only exists on the upper surface and the side surface of the bracket; or, a flexible printed circuit board (Flexible Printed Circuit, FPC) routing form, the antenna routing is pasted on the surface of one side of the structural part in the form of FPC; or, using the laser direct structuring (Laser-Direct-structuring, LDS) routing form, the antenna routing is laser-carved on the on one side of the structure. [0003] However, the above several forms will have the following problems: [0004] 1) In order to ensure the efficiency of the antenna, it is generally required that the height of the bracket or...
