A wideband circularly polarized monopole antenna fed by a coplanar waveguide is proposed. The monopole antenna is placed inside a G-shaped ground plane. Due to the asymmetry in the structure, two orthogonal modes out of phase by 90° are excited, which generate circular polarization. The measured results exhibit a 3-dB axial ratio bandwidth of 26.21% (2.42 GHz − 3.15 GHz), and −10 dB reflection coefficient bandwidth (|S11| < −10dB) of 35.16% (2.25 GHz – 3.21 GHz).
