Abstract

An offset CPW-fed dual-band circularly polarized printed antenna consists of a tilted asymmetrical U-shaped patch and a deformed ground plane is presented. The antenna could generate dual circular polarization radiation at 3.7/5.9 GHz due to tilted asymmetrical U-shaped patch, offset CPW feeding, and deformed ground plane which generates identical amplitudes and 90° phase between them. The 3-dB axial ratio bandwidth (ARBW) of antenna about 3.51% (3.64–3.77 GHz) and 14.9% (5.51–6.40 GHz) is achieved. The antenna resonates at about 3.58/7.28 GHz frequencies and provides impedance bandwidths (IBWs) of 370 MHz (3.40–3.77 GHz)/2850 MHz (5.15–8.00 GHz), respectively. The antenna shows good RHCP/LHCP radiation characteristics and acceptable gains in the dual operating bands.
