Abstract:

In this paper, some applications of metamaterial superstrates for directivity enhancement of cylindrical dielectric resonator antenna (DRA) mounted on corrugated ground plane are investigated. Three different types of superstrates, viz., split ring resonator (SRR), S-shape, and cubic high dielectric resonator (CHDR) are discussed. The metamaterial structure is used as a lens to improve the directivity of DRA and the corrugated ground to suppress back lobes. � 2017 IEEE.
