Abstract

The characteristics of a novel broadband artificial magnetic conductor (AMC) design based on a unilayer FSS with hexagonal unit cells and without via-holes are presented by means of FEM simulations and measurements in an anechoic chamber. A comparison between this novel design and other well-known designs is carried out in terms of AMC operation bandwidth. The designed structure shows polarization-angle independence, and its angular stability under oblique incidence is also analyzed based on measurements.
