Abstract
A wideband dual-feed dielectric resonator antenna (DRA) is proposed by stacking five-layer cross dielectric resonators and dual-port coaxial feeds. The proposed DRA can realize reconfigurable polarization states among right-hand circular polarization, left-hand circular polarization and three linear polarizations at 0°, ± 45°. The impedance bandwidth of DRA is 93.6% from 6.05 to 13.4 GHz. The 3 dB axial ratio bandwidth for circular polarization states is 87.8% from 3.50–8.50 GHz and the overlapped of impedance bandwidth and axial bandwidth is from 6.05 to 8.50 GHz with gain no less than 5 dB.
