A compact CPW fed rectangular slot antenna with split ring resonator for WIMAX and WLAN applications

Abstract

This paper presents the design and analysis of a coplanar waveguide fed rectangular(CPW) slot antenna with split ring resonator(SRR) and closed ring. The overall dimension is 26 × 31 × 1.6 mm3. The antenna covers the frequency range of 3.28 GHz–4.15 GHz and 5.15 GHz–5.58GHz with impedance bandwidth(<-10dB) of 1.17GHz and 0.43 GHz respectively. Good radiation performance is observed for both bands. The antenna is suitable for WIMAX and WLAN applications. Parametric study is explored for optimum performance.
