摘要

本文提出了一种具有单层非均匀超表面的高孔径效率法布里-珀罗谐振腔天线(FPRCA)。设计具有不同反射幅值的非均匀层板，保持反射相位恒定，使天线孔径电场分布均匀，实现高增益和高孔径效率。为了验证所提出的单层非均匀超表面层，仿真并设计了一个孔径为4 λ× 4 λ的10 GHz FPRCA。工作频率为10 GHz时，FPRCA的增益为22.4 dBi，孔径效率高达86.4%。与以往发表的具有多层叠加层的高增益、高孔径效率的FPRCA相比，本文提出的FPRCA在单层叠加层的同时实现了高增益和高孔径效率。

A High-Directivity and High-Aperture Efficiency Fabry-Perot Resonator Cavity Antenna with Single-Layer Nonuniform Metasurface Superstrate

In this work, a high aperture efficiency Fabry-Perot resonator cavity antenna (FPRCA) with a single-layer nonuniform metasurface superstrate is proposed. The nonuniform superstrate is designed with different reflection amplitudes as well as maintain a constant reflection phase to uniformize the antenna aperture electric field distribution and realize high gain as well as high aperture efficiency. To validate the proposed single-layer nonuniform metasurface superstrate, a 10 GHz FPRCA is simulated and designed with 4 λ× 4 λ aperture size. At the working frequency of 10 GHz, the gain of the FPRCA is 22.4 dBi -and the aperture efficiency is up to 86.4%. Compared to the previous published high-gain and high-aperture efficiency FPRCAs with multilayer superstrate, the proposed FPRCA simultaneously realizes high gain as well as high aperture efficiency with a single-layer superstrate.
