A compact CPW-fed arrow shaped monopole antenna for UWB applications

A compact Ultra wide band Arrow-shaped antenna fed by Coplanar Waveguide (CPW) is presented. The antenna has compact size of 17 mm×18 mm. It provides band width ranging from 3.7 GHz to 10.8 GHz. The bandwidth can also be varied by varying extrusion depth T and width of arrow shaped structure W
₂
, and Ultra wide bandwidth is achieved. Details of antenna are presented with parametric study. The fundamental parameters return loss, VSWR, radiation pattern are obtained, which meet standard specifications. Method of moments based IE3D simulator is used to analyze antenna. Radiation pattern curves were drawn at resonant frequencies and discussed. It provides satisfactory performance and small structure makes antenna suitable for Ultra wide band wireless applications.
