Abstract
This work presents a dielectric resonator on patch-electronically steerable parasitic array radiator (ESPAR) with wide impedance bandwidth for modern wireless applications. Enhancement of impedance bandwidth has been achieved by employing dielectric resonator on top of patch resonator as a compact constituent radiating element of the ESPAR array. A 3-element switched beam ESPAR array has been implemented at 15 GHz. Switching is based on PIN-diodes. The achieved impedance bandwidth is more than 24% which is the widest in comparison to DR based ESPARs in the literature. The antenna achieves beam steering in 0°, +25° and −25° directions with maximum gain of 8.26 dBi. Full wave simulations have been presented.
