Abstract
A dual-polarized dielectric resonator antenna (DRA) of simple structure is presented with very high isolation and lower cross-polarization. Its measured isolation reaches 46.8 dB within the impedance bandwidth of larger than 12.5% by using the H/U-shaped slot coupling with multi-stub feed lines. The measured cross-polarization level is -21.4 dB and -18.1dB for two ports, respectively. This DRA can be expanded into a large array for the synthetic aperture radar and wireless application.
