Cylindrical Dielectric Resonator Antenna Array with Beam Steering Capability

Abstract

In the proposed work, linear array of four Cylindrical Dielectric Resonator Antenna having beam steering capability has been designed and investigated. A specific progressive phase distribution between the array elements is controlled by introducing the appropriate delay lines in the feeding network. No need of any phase shifter and biasing network make the array design simple and less costly. The proposed design with impedance bandwidth of 500MHz at 7.75GHz frequency along with the gain of nearly 8.5dBi could be used in radar communication and other wideband wireless applications operating in X-band for moving targets.
