Abstract
In this presented work, Split Ring Resonator (SRR) is arranged in 7X7X4 form to create a metamaterial superstrate which is incorporate on patch antenna. The SRR based metamaterial slab is analysed with Nicolson–Ross–Wier approach to extract the effective parameters of the medium. The Extracted parameters Shows that the relative permeability of the slab is near zero in the vicinity of the resonant frequency of the designed antenna. The experimental results clearly reflect that the gain of the superstrate loaded patch improves by 7.6 dB with variation less than 1 dB in the vicinity of resonant frequency. Structures are simulated on Ansoft HFSS v14 and experimentally verified.
