Abstract
Design of four element rectangular shaped dielectric resonator antenna (RDRA) array is presented for wireless applications. The RDRA array is excited by rectangular conformal patch (RCP) connected to microstrip line which is an effective feed mechanism and more efficient in energy coupling. Simulation result shows that the proposed antenna achieves an impedance bandwidth from 4 GHz to 7.1 GHz covering wireless bands. Parametric studies have been carried out by varying the RCP and the ground plane of the final design. The proposed antenna gives the appreciable gain and better radiation pattern at the resonant frequencies.
