A CPW-fed Printed Monopole Antenna using Circular CSRR for WCDMA/WiMAX/WLAN Applications

摘要

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 x 28mm x 1.6mm, which is suitable for all wireless applications.
