Design of patch antenna based on metamaterial

Abstract: Many needs of new generation communication system would be filled by electrically small, efficient antennas having significant bandwidth, if we reconcile these contradictory requirements. The introduction of metamaterials has provided an alternate design approach to obtain efficient electrically small antennas. These are the artificial materials which have engineered electromagnetic responses that are not readily available in nature. A micro-strip antenna based on metamaterial is proposed in this paper is to investigate the response of an antenna enclosed in metamaterial. With this design the return loss of -43dB has been achieved at the frequency of 1.6142 GHz.
