Metamaterial have been shown to enhance specific performance parameters of low profile antennas. In this paper we investigate appreciably enhancement of the gain & radiation pattern of a low profile micro strip patch antenna by placing a metamaterial slab above it (as a super strate) using CST MWS simulator. This paper proposes a metamaterial super strate surface as a reflective surface for micro strip patch antenna (MPA). The MTM structure was a combination of the triangular SRR (TSRR) and the wire strip (WS) to obtain negative values of permittivity & permeability. The gain of the MPA with MRS is around 5 dB higher than that of conventional MPA on FR4 substrate. These improvements were due to negative refraction characteristics of LHM structure that converts into super-lens, when placed in front of the antenna. The small spacing between MRS and the patch surface was another merit in the present design, which was as low as ?/10 as it results in low profile antenna design, that will suits in modern wireless communication system.
