Abstract

A novel dual-band and dual-sense circularly polarized coplanar waveguide (CPW) fed planar antenna with an asymmetric rectangular slot is presented. An F-shaped feed line is protruded from the signal line into the slot. Circular polarization is obtained due to the F-shaped feed line and asymmetry in the slot. Axial ratio bandwidth is significantly enhanced by placing parasitic elements adjacent to the feedline. The antenna has a size of 63.5 × 55 mm². The measured results agree well with simulation. The measured impedance bandwidths are 26.04% (1.57 GHz–2.04 GHz) for the lower band and 18.93% (2.87 GHz–3.47 GHz) for the upper band. The measured 3 dB axial ratio bandwidths of lower band and upper bands are 22.22% (1.6 GHz–2 GHz) and 10.53% (3.15 GHz–3.5 GHz), with respect to 1.8 GHz (RHCP) and 3.325 GHz (LHCP), respectively.
