Full-wave Analysis of High-power Circularly Polarized Reflective Array Antenna

Abstract

The traditional analysis method of circularly polarized reflective array antenna is insufficient in analyzing the radiation characteristics of antenna, which leads to low accuracy in full-wave analysis of antenna. Therefore, a high-power full-wave analysis method of circularly polarized reflective array antenna is proposed in this paper. Firstly, the working principle of circularly polarized reflective array antenna is studied, and relevant parameters are collected. Then, according to the parameters, the phase distribution, radiation characteristics, aperture efficiency and unit spacing of reflective array antenna are analyzed. The performance of the designed array antenna is tested by the simulation experiment, and the superiority of this method is verified. The phase difference of this method is 7.7°±4°, and the errors of gain and axial ratio are 0.7dB and 0.5dB, respectively. The test results are in good agreement with the simulation results, which proves that this method can obtain high-precision analysis results of circularly polarized reflective array antenna.
