A CPW-fed printed monopole antenna using circular CSRR for WCDMA/WiMAX/WLAN applications

Abstract

In this paper we purpose a novel compact size CPW-fed complementary Circular split ring resonator (CSRR) printed antenna for WLAN, WiMAX and WCDMA applications. The antenna consists of micostrip line and CSRR unit cell, with a fully covered ground plane. The simulated results show that the antenna can yield an impedance bandwidth of 1.87–2.2 GHz, 3.45–4 GHz and from 5.5–5.9 GHz band with reflection coefficient less than −10dB. The antenna has found nearly omni-directional and gain is around 3dBi for all the bands. The overall dimension of the antenna is 14 × 28mm × 1.6mm, which is suitable for all wireless applications.
