Abstract

In this paper, a circular metallic plate antenna suspended by shorting pins over a ground plate with a novel stepped coaxial feed is proposed for miniaturized ultra-wide band applications in the frequency range 2.6-13.2 GHz. This antenna achieves acceptable miniaturization and provides excellent UWB input impedance bandwidth and stable radiation patterns. It achieves about 110 percent bandwidth. The proposed antenna achieves both miniaturization and high bandwidth in UWB wireless applications, which are quite contrary and opposing characteristics. The performance of the proposed antenna is quite good compared to other similar structures.
