摘要

A single feed, four element rectangular Dielectric Resonator Antenna (DRA)array, with beam switching capability is proposed. A wide impedance bandwidth of morethan 25% at the center frequency of 1.95 GHz is achieved. Each DRA has two excitationstrips and four parasitic patches. The six cases are discussed; each case corresponds to adiverse radiation pattern. The antenna beam is switched in azimuth (θ=45°) at Φ=0°, 60°,120°, 180°, 240°, and 300°. The antenna gain is found to be more than 7 dB in most of thefrequency band of interest. A passive prototype is developed and tested to validate simulationresults. The comparison between the simulated and measured reflection coefficientsand the radiation patterns for the six cases is presented. A good agreement between themeasured and simulated results is observed.
