A metamaterial (MTM) loaded rectangular microstrip patch antenna is proposed for THz applications. Metamaterials are artificial structures designed to have properties that are not available in nature. They resemble natural crystals as they are built from periodically arranged nit cells, each with a side length of a. Metamaterial is a material which is having negative permittivity and permeability, and it can be regarded as an artificial medium with negative index of refraction. By using Metamaterial in antenna we can increase bandwidth, reduce antenna size and increase in radiator efficiency. This MTM can be used for improving the return loss, gain and radiation efficiency of the antenna. The antenna is simulated using HFSS software and the parameters such as return loss (S11), and gain are found respectively.
