Abstract :
High-gain, low-profile electromagnetic band-gap (EBG) resonant antennas based on frequency-selective-surface type (FSS) metamaterials are studied. The metamaterial is composed of the standard FR4 material with two different metallic patterns printed on both sides. We show that high gain can be achieved with superstrates as thin as lambdag/16, where the metallic patterns are optimised. Two examples are provided to demonstrate the effectiveness of the design scheme.
