Abstract

This paper focuses on improving the directive properties of a conventional patch antenna by using a known technique of applying metamaterial slab as a cover. The metamaterial under consideration is a modification of Pendry‟s SRR structure and is equivalent to two SRRs connected back to back. The unit cells were arranged in an array configuration, investigation of S- parameters was done for checking the Negative index property. As expected with the use of metamaterial as a cover, directionality of conventional patch antenna improved significantly and the 3 dB beam-width reduced. A conventional patch antenna generally shows 3 dB beam-width of ~80deg while the antenna presented in this paper with the metamaterial shows improved 3dB beam-width of 45 deg.
