Design and gain enhancement of a CPW-Fed dual band slot antenna using a metamaterial inspired superstrate

Abstract

The design of a Dual band slot antenna using complementary LC resonators is presented. Two complementary dual band LC resonators are used to achieve the response. A metamaterial inspired superstrate is then used to achieve gain enhancement at both the operating frequencies. The paper discusses the steps followed to realize the final design and presents the simulated results for the proposed structure. The novelty of this work lies in the simultaneous gain enhancement performance observed at both the bands of the dual band slot antenna structure using the superstrate.
