Abstract

A novel compact Ultra wideband antenna fed by CPW is presented. The antenna has a size of 29 mm × 31 mm. The antenna is excited by Pot shaped inner tuning stub. It provides band width ranging from 2.9 GHz to 10.2 GHz which covers Ultra Wide bandwidth. The antenna can be easily integrated with radio frequency circuit for low cost. Details of antenna are presented with parametric study. The bandwidth is varied by varying feed gap `g´ and intrusion depth L₃ and ultra wideband with is obtained. The antenna is Omni directional in operating range and it has good radiation efficiency. 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.
