Metamaterial Based Radome Applied to a Microstrip Antenna

Abstract

In this paper an application of radomes designed with square Split Ring Resonator (SRR) cells with DNG metamaterial characteristics is presented, to improve the gain of a Microstrip Rectangular Patch Antenna without reducing its bandwidth. The radome structure consists of layers of metamaterials alternated with air and forming three radomes, each one with 117 cells. The parameters of the cell and all the distances in the complete structure are optimized via CST software to improve antenna characteristics.
