Abstract

The invention discloses an H-slot coupled feeding circularly polarized antenna, which comprises a square antenna base (5), an antenna unit and an antenna feed network (3) which are arranged on the square antenna base (5), and a radio frequency connector (4) fixed under the square antenna base (5). The H-slot coupled feeding circularly polarized antenna disclosed by the invention has the advantagesof wide bandwidth, small size, reliable structure and fixation, light weight and the like, and can effectively solve the problems of large size, complicated installation and the like.

Description

technical field [0001] The present invention relates generally to the field of data link communication antennas. More specifically, the present invention relates to S-band broadband circularly polarized antennas. Background technique [0002] The data link antenna is usually installed on the surface of the carrier and completes the data transmission, which often requires high gain, wide bandwidth and miniaturized design. The traditional microstrip antenna has the characteristics of easy conformality, etc., but the bandwidth of the traditional microstrip antenna is only about 4%, and it is difficult to achieve a wider bandwidth. The coupled-fed microstrip antenna can effectively widen the bandwidth, and the bandwidth reaches about 15%. However, the size of the coupled feed antenna is large, and it is difficult to conform and fix the antenna with the carrier. Contents of the invention [0003] One of the technical problems that the present invention aims to solve relates ...
