Wideband Dielectric Resonator Antenna with Polarization Reconfigurability
In this paper, a novel wideband polarization reconfigurable dielectric resonator antenna (DRA) is proposed. Since only five p-i-n diodes are needed to implement the reconfigurablility and the reconfigurable circuit is isolated from the DRA by the ground plane, the antenna shows a simple structure. By combing the two resonant frequencies of DR mode and DR-loaded cross-slot mode, the antenna can achieve a wide operating bandwidth. Simulated results show that the antenna can achieve a 3-dB axial ratio (AR) bandwidth of 16% for circular polarization (CP) states, an impedance bandwidth of 19% for linear polarization (LP) state with a cross-polarization level of better than 25 dB, and a peak gain of 7 dBi for all states.
