Abstract

The invention aims to provide a low frequency oscillator with a simple structure, small volume and little influence on a high frequency pattern. The low frequency oscillator comprises an upper conductor layer, an intermediate dielectric layer and a lower conductor layer. The upper conductor layer comprises 2-5 pieces of upper oscillator segments made of metal, and the upper oscillator segments arearranged in a straight line and separated from each other. The lower conductor layer comprises 2-5 lower oscillator segments made of metal, and the lower oscillator segments are arranged in a straight line and separated from each other. The projections of the straight line arranged by the upper oscillator segments and the straight line arranged by the lower oscillator segments on the plane wherethe intermediate medium layer is located coincide, and the projections of the upper oscillator segments and the lower oscillator segments on the plane where the intermediate medium layer is located are mutually staggered. The upper oscillator segments are provided with short circuit branch upper conductors, and the lower vibrator segments are provided with short circuit branch lower conductors. The upper oscillator segments and the lower oscillator segments are conducted hand in hand through the short circuit branch upper conductors and the short circuit branch lower conductors. The manufacturing cost of the low frequency oscillator is relatively low, and the low frequency oscillator has little influence on the high frequency pattern and S parameters.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a low-frequency vibrator for a multi-frequency antenna. Background technique [0002] A low-frequency radiation unit and a high-frequency radiation unit are included in a mobile communication multi-frequency antenna at the same time. Ordinary low-frequency radiation units have an impact on high-frequency performance, causing distortion in the high-frequency pattern and affecting the performance of mobile communication networks. In order to solve this problem, many low-frequency vibrators with different structures are used at present, but these low-frequency vibrators are generally difficult to design, and they still affect the high-frequency pattern when used. [0003] Therefore, it is necessary to further improve the structure of the existing low-frequency vibrator used for multi-frequency antennas. Contents of the invention [0004] The object of the present invention is t...
