Simulation results 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 metanmterial patch antenna.展开更多

文摘A patch antenna, a metamaterial patch antenna and a proposed metamaterial patch antenna, are simulated and compared. Simulation results 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 metanmterial patch antenna.
