A broad-side coupled SRR inspired CPW fed dual band antenna for WiMAX and WAVE applications

Abstract

In present scenario, this paper intends to demonstrate the practicality of a miniaturized coplanar waveguide fed metamaterial inspired antenna that can be effectively operated at dual bands. A broad-side coupled Split Ring Resonator is used to obtain dual bands with an impedance bandwidth (−10 dB) of 840 MHz (3.00–3.84 GHz) and 310 MHz (5.94–6.25 GHz), which resonates at dual bands, viz., 3.42 GHz and 6.07 GHz. The impedance bandwidth (S11 < −10 dB) is 25% for the first band and 5.1% for the second band. The size of the antenna is 31×25×1.6 mm3 realized on a low-cost FR-4 Epoxy substrate. This antenna can be effectively utilized in worldwide interoperability for microwave access (WiMAX) and wireless access in vehicular environments (WAVE) applications. The prototype of the proposed antenna is fabricated and measured. Simulated and measured results are in agreeing nature. Experimental and simulated analyses of the antenna including parametric and dispersion characteristics are dealt in this communication.
