| Abstract: | A compact coplanar waveguide (CPW) fed close ring resonator (CRR) loaded four-element metamaterial (MTM) array antenna for wireless application is designed and discussed in this article. The array is designed with corporate feeding network, arranged in a manner to offer 3 dB power at its each element. The proposed 1 × 4 MTM array antenna offers a fractional bandwidth of 10.18% with respect to the resonance frequency of fr = 2:26 GHz. At the resonance frequency of 2.26 GHz, the proposed 1 × 4 MTM array antenna offers a gain of 5.10 dBi in the direction of broadside radiation. Each element of the proposed array antenna consists of CRR, which removes the requirement of via and allows the design of a uniplanar MTM array. The overall electrical size of the single element antenna shows compactness of 0:255λ0×0:155λ0×0:012λ0, where λ0 is the free space wavelength at its resonance frequency of fr = 2:3 GHz. The proposed MTM array antenna is designed and simulated on ANSYS HFSS 14.0, and simulated results are verified with the fabricated proto-type. [ABSTRACT FROM AUTHOR] |
