Directional Microstrip Antenna by using Metamaterial Superstrate in Fabry-Perot Cavity

Authors

Abstract

Recently Fabry-Perot (FP) resonator structures for enhancing directivity have found wide use in antenna design. FP Resonator antenna generally consists of primary radiator backed with a metal ground plane and a partially reflective surface (PRS). In this paper metamaterial unit cells is utilized as PRS in FP cavity for increasing microstrip antenna directivity. As a novel design an array of Omega unit cells is proposed and designed. FP antenna performance with Omega cover and superstrate of patch and SRR is simulated and compared. For validation of purposes, the antenna is designed and simulated through using of two different 3D full-wave electromagnetic simulation tools CST Microwave Studio and Ansoft’s High Frequency Structure Simulator (HFSS).
