Abstract-A patch antenna, a metamaterial patch antenna and a p roposed metamaterial patch antenna, are simulated and compared. Simulation resul ts show that the proposed antenna can concentrate so well radiation energy into broadside direction that the antenna gain is increased and the side lobe level is decreased. Therefore, the gain of the proposed metamaterial patch antenna is improved by 2 dB than that of the ordinary metamaterial patch antenna.
Key words-proposed metamaterial; patch antenna; gain
