Abstract :
A dual-polarized quasi-cubic dielectric resonator antenna (DRA) with a simple multi-stub feeding network is introduced for the array applications. The measured impedance bandwidths of dual ports are 18.5% and 20% , and the measured isolation is better than 45dB over an 11.7% bandwidth. This DRA can be expanded into large arrays for the synthetic aperture radar (SAR) and wireless systems.
