Abstract :
In this paper, a portable Dielectric Resonator Antenna design with broadside radiation using Advanced Design System (ADS) is presented. The total volume of the antenna is reduced and impedance matching for a wide bandwidth are obtained by using a solid rectangular dielectric resonator mounted on a vertical ground plane edge instead of perpendicular ground plane edge. To improve the impedance matching and the radiation pattern two dielectric pieces have been removed to form an `A´ shaped Dielectric Resonator. This modified Dielectric Resonator Antenna would provide much better broadside radiation characteristics.
