Abstract :
Design of Notched Chamfered Rectangular shaped two elements Dielectric Resonator Antenna (DRA) array is presented for wireless (WLAN and WiMAX) applications. In this paper, the DRA array is excited by conformal patch connected to microstrip line which is an effective feed mechanism and more efficient in energy coupling than other types of feeding techniques. Simulation results show, the proposed antenna achieves an impedance bandwidth from 2.18 to 3.75 GHz and 4.84 to 5.14 GHz covering 2.4, 3.6 and 5 GHz WLAN bands and 3.4 to 3.7 GHz WiMAX bands. Comparison is done among various shapes of the rectangular DRA arrays (Simple Rectangle, chamfered and chamfered with notched). A parametric study is carried out by varying the ground plane´s dimension of the final design. The proposed antenna gives the appreciable gain and radiation pattern at the resonant frequencies.
