Abstract

The invention relates to the technical field of wireless communication, in particular to a broad band circular polarization plane gap quaternary antenna array which comprises a circular polarization gap radiation array and a microwave medium layer, wherein the circular polarization gap radiation array is arranged on the microwave medium layer. The circular polarization gap radiation array comprises four circular polarization gap radiation units and a plurality of feeders, wherein, every two circular polarization gap radiation units are connected in parallel by the feeders into a radiation branch, and two radiation branches are connected in parallel by the feeders into a radiation trunk path, and the circle centers of the four circular polarization gap radiation units are on the same axis. The invention has the characteristics of miniaturization, complanation and broad frequency band, and solves the problem that a plane gap antenna cannot be realized easily; in addition, the structure of antenna units are arranged in a 1*4 linear array, thereby improving gain and frequency band.

Description

technical field [0001] The invention relates to a device in the technical field of wireless communication, in particular to a broadband circularly polarized planar slot four-element antenna array based on a coplanar waveguide feeding network. Background technique [0002] With the development of satellite communications and the increasingly crowded radio channels, radio technology is developing towards shorter and shorter millimeter waves and submillimeter waves. Millimeter wave has the characteristics of extremely wide bandwidth, high resolution, and all-weather operation. The size of millimeter wave components is small, and it is easier to miniaturize and integrate. Therefore, millimeter wave technology has a wide range of applications in military, communication, security and other fields. But traditional antennas have encountered new difficulties in the millimeter wave band. First of all, with the increase of frequency, the requirements for processing accuracy are getti...
