Design of High Gain Broadband Antenna Based on Fabry-Perot Resonator

Published: 25 May 2020 Publication History

Abstract

Firstly, this paper studies the shortcomings of traditional PRS(Partially Reflective Surfaces). To solve this problem, a partially reflective surface with positive reflective phase gradient is proposed. Compared with the traditional structure, the partially reflective surface energy proposed in this paper can achieve a wider - 3dB gain bandwidth. The Fabry-Perot resonant cavity antenna is formed by loading the structure above the feed antenna, and is simulated by HFSS. The simulation results show that the gain of the antenna is increased by 3.7dB, the -3dB gain bandwidth is over 35%, and the -10dB impedance bandwidth is widened from 8.5% to 11.2%.
