Abstract

Abstract In present work a wide band and high gain cylindrical dielectric resonator antenna working in X-band has been designed and validated experimentally. First the bandwidth of the antenna has been enhanced by placing the thin dielectric layer between antenna and feed network. Next gain of the antenna has been increased by placing a layer of high dielectric material at nearly λ/2 distance as superstrate. The proposed design with impedance bandwidth of 3 GHz and gain nearly 11dBi could be used in satellite communication and other wideband wireless applications operating in X-band.
