Abstract
A novel wideband circularly polarized reconfigurable antenna for 5G devices is presented in this paper. Left hand and right-hand circular polarizations were achieved using the sequential phase rotation feeding network based on 90° hybrid coupler. The proposed antenna has a bandwidth (with AR ≤ 3 dB) of 24.8% and 4% for right hand circular polarization (RHCP) and left-hand circular polarization (LHCP) mode, respectively. At 3.75 GHz, the degree of circular polarization is 42° in LHCP mode and 51° in RHCP mode showing the potential of this proposed antenna for modern 5G terminal devices.
