Corporate feed based metamaterial antenna for wireless applications

In recent years, metamaterial based planar antenna design is gaining popularity because of enhanced radiation. Also, coplanar waveguide (CPW) fed antennas provide inherent impedance matching for broader frequency range. In this paper, analysis of high efficiency dual band antenna for advanced LTE and other wireless applications is discussed. This proposed design uses two annular rings for the radiating layer with CPW feed. It uses split ring resonator elements for achieving metamaterial property. Resonance is achieved at 2.8 and 4.6 GHz with a maximum gain of 5.53 dB. The impedance bandwidth of the proposed antenna is 450 MHz.
