Metallic EBG superstrates for dual polarized sectoral base station antenna

摘要

In this paper we present a novel approach to design a dual polarized sectoral antenna using a double layer of metallic EBG materials working on orthogonal polarizations as a superstrate. This antenna is able to radiate in vertical, horizontal and dual polarization with a wide (or broad) radiation pattern form, i.e. presenting at least 60deg angular beamwidth in the azimuth plane. EBG antennas with sectoral pattern are usually designed only for vertical and horizontal polarization. In this paper, we also present dual polarization.
