N2 - In this paper, a novel circular patch antenna is proposed to have Zeroth Order Resonance(ZOR) generated based on the Metamaterial Composite Right- and Left-Handed(CRLH) structure. Making the in-phase electric field over the entire antenna other than a half-wavelength as the fundamental resonance mode of a ordinary microstrip patch or its positive multiple, the metallic patch is suggested to be capacitively coupled with only one surrounding circular ring, different from the previous 1D ZOR antennas commonly having several metal cells in line. The performance of the proposed antenna is simulated by a 3D field solver that inputs the sizes of the physical structure corresponding to the equivalent circuit designed to have ZOR at 2.4 GHz. Consequently, the resonance frequency, the gain and the antenna efficiency are observed 2.4 GHz, 5 dB and 98%, respectively. Besides, the important property of the proposed antenna is addressed as the combination of the low-cost low-profile as an advantage of microstrip patch antennas, and the omni-directional field pattern typical of monopole antennas.
