Abstract

A compact bandwidth enhanced antenna using Split Ring Resonator (SRR) for WLAN/WiMAX/Satellite applications is presented. As the wireless modules continue to shrink, there exists a drastic demand for a compact antenna. In addition to this, the effective integration of an antenna in wireless devices acts as stand-alone implement to mitigate the effects of noise fading. The presented antenna consists of a split ring resonator, two C-shaped slot and a coaxial feed. Compactness in the design is achieved with the help of coaxial feeding technique. The etching of SRR creates a resonance at 6 GHz (WLAN) band, with S11 <-10 dB bandwidth ranging from 5.46 – 6.7 GHz (1240 MHz). Bandwidth enhancement in the proposed design (at 6 GHz), is accomplished by the two C-shaped slots placed at the left and ride side of the radiating patch, just below the SRR. Due to the placement of two C-shaped slots the bandwidth of the proposed antenna gets enhanced from 1240 to 3120 MHz. The antenna has a size of only 0.4 λ0 × 0.36λ0 × 0.05λ0 = 20 × 18 × 2.54, at a resonance frequency of 6 GHz. The antenna exhibits bi-directional and Omni-directional radiation characteristics in E and H-plane, respectively. Compact size, good impedance matching and stable radiation patterns are observed across the operational bandwidths. The aforementioned advantages make the proposed antenna suitable for WLAN/WiMAX/Satellite applications.
