Abstract: A new patch antenna system with a metamaterial cover is presented in this paper. The impedance, radiation pattern, and directivity of such an antenna are studied. A performance comparison between the conventional patch antenna and the new metamaterial patch antenna is given. The results show that the directivity of the metamaterial patch antenna is significantly improved. The effect of the metamaterial cover’s layer numbers on the radiation pattern of the patch antenna is also studied.

Key words: Directivity, Metamaterial, Patch antenna
