Abstract: This paper presents a novel low profilehigh Gain Antenna with side band suppression by minimizing the return loss in Patch antenna. A �Patch antenna� is mounted on a flat surface and it is a type of low profile radio antenna. It consists of a flat rectangular sheet or large sheet mounted on a metal patch of metal called ground plane.The existing material to design the antenna is normal metals. Those metals have positive refractive index. It may leads to various problems such as high return loss and poor directivity. To mitigate these problems our paper focus on usage of meta material for antennas and to measure the performance of antennas such as gain, directivity , radiation pattern and return loss.This design consists of Waveguide as input,substrate with metamaterial loaded and microsrtrip line patch.The proposed antenna design work as about 75% miniaturization compared to the conventional patch antenna. The usage of metamaterial has following advantages. It has negative refractive index and so the directivity can be improved and the return loss can be decreased.The tool used in this project is HFSS software (High Frequency Structure Simulator).
