Abstract :
This paper presents the design of an antenna with small footprint, small volume and full ground plane for ultrawideband (UWB) systems. The design consists of two different dielectric segments, which reside above a ground plane, and is excited by a small metallic patch connected to a coaxial probe. The selected dielectric resonator (DR) bandwidth is enhanced by removing some dielectric and forming an air cavity within the structure. The volume of proposed DRA is also reduced by adding a finite planar conducting wall. A full ground plane is used to ensure that most of the power radiates to upper hemisphere. The proposed DRA with good radiation characteristics offers a simulated bandwidth of 68% between 4.6 and 9.3 GHz with |S11| <; -10 dB.
