Abstract :
Previously developed MATLAB code for designing planar (2D) metamaterial broadband ground planes is extended to design volumetric (3D) metamaterial structures. A 3D ground plane designed to operate as an artificial magnetic conductor (AMC) in the 225-450 MHz frequency range is presented. Its performance when used as the ground plane of the planar long slot array (PLSA) antenna and cylindrical long slot array (CLSA) antenna is evaluated and compared to the previously used absorbing ferrite ground plane, resulting in enhanced gain performance due to in phase reflection and minimal absorption.
