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.
