Polarization tunable dielectric resonator antenna with quasi-lumped quadrature coupler
A full polarization reconfigurable dielectric resonator antenna (DRA) is proposed in this paper. Fed with a quasi-lumped quadrature coupler (QLQC), the DRA can achieve vertical linear, horizontal linear, left-handed circular and right-handed circular polarization simply by changing the mode and input port of the hybrid. A reconfigurable DRA operating at 3.5 GHz has been investigated. Due to the wideband characteristic of DRA, the impedance bandwidth (S11 <; -10dB) of linear polarization (LP) is 12.6% with reasonable gain. The bandwidth of circular polarization is 15.1% with S11 lower than -10 dB and gain in the boresight direction over 5dBi.
