Abstract :
A novel design of a circularly polarized CPW-fed antenna for WiMAX/WLAN application is presented. The antenna consists of a CPW-feed structure, two square slots around both sides of the feed and two interleaved parasitic resonance strips inserted within each of the square slots. The proposed antenna gives circular polarization at the centre frequency of 2385 MHz with 3 dB axial ratio bandwidth of about 3.77% and impedance bandwidth of 13.39%. The designed antenna has a small size of 30×40 mm2.
