Abstract

This work presents the effect of the height variation of an AMC, artificial magnetic conductor. The AMC is a metal-dielectric structure which has a high surface impedance inside a forbidden frequency band. The prototype for this work is first designed to have a bandgap around 1.9 GHz. The variation of the structure height allows a dislocation on the resonance frequency and the forbidden frequency band, bandgap, as is shown in the measured results. The experimental design approach is based on simple EM formulation.
