Abstract
A millimeter-wave (mmWave) dielectric resonator antenna (DRA) with multifunctional reconfigurability is proposed. The design integrates two PIN diodes into each arm of the feeding cross-slot, allowing electronic control over the effective arm length. This configuration enables the antenna to switch between three polarization states. Linear polarization (LP) is achieved when all diodes are either forward-biased (ON) or reverse-biased (OFF), resulting in dual-bandwidths. In contrast, circular polarization (CP) is realized when the diodes on one arm are ON and those on the other arm are OFF. Switching the biasing states of the four PIN diodes reconfigures the CP sense from left to right hand CP, or visa versa. The CP mode delivers a gain of over 6 dBic with an impedance bandwidth of ~20%.
