摘要：
A compact ultra wideband antenna fed by microstripline is presented. The antenna has a size of 30 mm x 35 mm. The antenna is excited by hexagonal shaped tuning stub. It provides bandwidth ranging from 3.1 GHz to 10.2 GHz. A single EBG cell is placed near the feedline which provides band-stop characteristic in frequency range 3.3-4.2 GHz to avoid interference from WiMAX band. 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 the width, height of hexagonal shaped structure and ultrawide bandwidth is obtained. The antenna has stable radiation pattern in operating bandwidth 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.
