Novel jagged-shaped ultra-wideband antenna

Abstract

In this article, we introduce a novel antenna with jagged-shaped patch and fed by a coplanar waveguide(CPW). This article also shows two-order optimization of patch and ground plane optimization. The size of the substrate is 30 mm× 26 mm× 0.8 mm and the substrate material uses RT5880 with relative permitivity of 2.b The simulations and experimental results demonstrate that the impedance bandwidth of antenna can be achieved from 2.2 GHz to 10 GHz. The antenna can be widely used in ultra-wideband (UWB) system.
