Volumetric MSRR-based AMC for low-profile antenna application

Abstract

This paper is dedicated to the study of volumetric MSRR-based AMC structure. The characteristics of a single MSRR unit cell are investigated; and a volumetric miniaturized AMC block is then designed. In order to validate the approach used to simulate an infinite periodic structure, a block of nine aligned layers is then simulated. The next step is to add a printed dipole antenna as an application to validate the performance of the AMC block. The results are very excellent and promising if compared with the simple dipole antenna as an enhancement of 5 dB is achieved considering the directivity. The front to back ratio is found to be about 20 dB.
