In this paper, a design for rectangular microstrip patch antenna loaded with metamaterial has been proposed, where mu negative material has been chosen as the metamaterial. It has been shown that the proposed design supports dual band configuration. For the two resonance frequencies, the antenna also supports two different types of radiation pattern. As no etched slot, shorting pins or air gap have been used to increase gain or directivity factor, this design is compact in shape and size as well as simple and easy to manufacture. The proposed antenna design will create new opportunities in the designing and manufacturing of small scaled radiators with enhanced performance, which is of demand for many applications.
