摘要

本文提出了一种极宽带法布里-珀罗腔天线(FPCA)。采用梯度介电常数部分反射面(PRS)，可显著提高3db增益带宽。为了获得有效梯度介电常数，对具有不同孔尺寸的单层板进行了研究，结果表明，有效梯度介电常数随孔尺寸的增加而减小。分析并优化了不同介电常数梯度阶跃下的增益性能。对ku波段FPCA进行了仿真。仿真结果表明，该设计具有较高的效率，最大增益为17.3dBi, 3db增益带宽为58%。

A Design of Extremely Wideband Fabry-Perot Cavity Antenna

This paper presents an extremely wideband Fabry-Perot cavity antenna (FPCA). By using gradient permittivity partially reflection surface (PRS), the 3-dB gain bandwidth is improved dramatically. To achieve effective gradient permittivity, a single-slab superstrate with different size holes is studied, showing that the effective gradient permittivity decreases with the dimension of holes increase. The gain performance with different gradient steps of permittivity is analyzed and optimized. A Ku-band FPCA is simulated. The simulated results demonstrate that the proposed design has high efficacy, which can achieve maximum gain of 17.3dBi with 3-dB gain bandwidth of 58%.
