摘要

首先，本文研究了传统部分反射面技术的不足。为了解决这一问题，提出了一种具有正反射相位梯度的部分反射曲面。与传统结构相比，本文提出的部分反射表面能可以实现更宽的- 3dB增益带宽。通过在馈电天线上方加载结构形成法布里-珀罗谐振腔天线，并用HFSS进行了仿真。仿真结果表明，该天线的增益提高了3.7dB， -3dB增益带宽超过35%，-10dB阻抗带宽从8.5%拓宽到11.2%。

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

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%.
