Abstract :
In this paper, a novel microstrip patch antenna is proposed which has Zeroth Order Resonance (ZOR) mode and is based on the Composite Right and Left Handed (CRLH) structure. The metallic patch is suggested to be coupled with four surrounding unit cells. It is different from the previous 1D ZOR antennas commonly having several metal cells in line or the conventional ZOR antennas of periodic mushrooms. The ZOR frequency, the gain and the antenna efficiency are observed 6.5 GHz, 2.12 dB and 90.3%, respectively. Besides, this proposed antenna has the omni-directional field pattern and achieves miniaturization.
