Abstract

The ability of novel and emergent high impedance conformal metamaterial surfaces to reduce the diameter of cylindrical microwave antennas while improving antenna operating performance characteristics will be experimentally explored for various structures. A full-wave analysis has been applied to an infinitely long cylindrical cavity that provides physical insight in the HIS/EBG coexisting operation. The proposed structures include resonant-cavity type antennas, of different profile thickness: λ/2, λ/4 and λ/6 operating around 2.3GHz.
