Abstract

A compact (40 mm x 35 mm) coplanar waveguide (CPW) fed slot antenna for circular polarization is presented in this paper. The antenna is designed and fabricated for applications in the ultra-wideband domain of wireless communications where circular polarization is also required. The axial ratio (AR) bandwidth of the proposed antenna is 35.46% (5.8 GHz– 8.3 GHz), while the experimental impedance bandwidth is from 2.8 GHz – 8.6 GHz. The experimental results are very close to the simulated results. The antenna displays a stable radiation pattern and a moderately high gain of around 5 – 6 dB in the useful band.
