On the gain enhancement of a wideband CPW-Fed circularly polarized antenna using FSS
In this paper a modified cross dipole Frequency Selective Surface (FSS) is utilized to increase the gain of a Circular Polarized (CP) antenna. The antenna is a Coplanar Waveguide (CPW) fed structure with modified Z-shaped radiating element. The FSS is used as a reflector. It is used to enhance the Right Handed Circular polarization (RHCP) gain and making antenna nearly unidirectional. The overall size of the antenna with FSS is 1.1λ0 × 1.1λ0 × 0.2λ0. The Antenna with FSS has an impedance bandwidth of 109 % (2.1-5 GHz) and Axial Ratio Bandwidth (ARBW) of 55.7 % (2.2-3.9 GHz). The antenna along with FSS has a peak boresight gain of 7.3 dB. The radiation patterns and Gains of antenna with and without FSS are also compared to discuss the effect of FSS on antenna performance.
