摘要

本文对由厚部分反射面覆盖的腔体构成的宽带法布里-珀罗腔(FPC)天线的辐射特性进行了解析分析和数值验证。厚prs被设计和优化为具有正斜率的反射相位，在天线工作带宽中具有非福斯特样响应。在较宽的频带内满足天线谐振条件，可获得较宽的辐射功率带宽。报道了厚- prs的反射系数与腔体结构内径向传播的漏波之间更为普遍和直接的关系。此外，本文还研究了一种基于漏波的功率强度公式，并利用金属介电层堆叠形成的PRSs进行了数值验证。

Overview of Wideband Fabry-Pérot Cavity Antennas with Thick Partially Reflective Surface

Radiation characteristics of wideband Fabry-Perot cavity (FPC) antennas formed by a cavity covered by thick partially reflective surfaces (PRSs) are shown analytically and verified numerically. Thick PRSs are designed and optimized to exhibit a reflection phase with positive slope with a non-Foster-like response in the antenna operational bandwidth. By satisfying the antenna resonance condition over a wide frequency band, a wide radiated-power bandwidth is obtained. A more general and direct relation between the thick-PRS's reflection coefficient and the radially propagating leaky-wave inside the cavity structure is reported. In addition, a leaky-wave based power intensity formula is studied and verified numerically using PRSs formed by stacks of metal-dielectric layers.
