and manufactured for operating in the microwave band at a frequency of 5.8 GHz, using
metamaterial technology which is a layer of 9-by-9 matrix of a Circular split ring resonators
(SRR). The MTM Superstrate can modify the radiation pattern and exhibit gain enhancement
about 5 dB higher than the maximum gain of the original patch. Simulation and discussion
results of the proposed antenna are presented in this letter.
