Abstract

In this paper a novel barbell-shaped planar antenna for UWB application is proposed. The antenna, composed of two symmetrical fractal patch radiators and partially grounded plane which are used to realize the characteristic of ultra-wideband (UWB), can occupy about 3.95 GHz bandwidth (from 3.45 GHz to 7.40 GHz), which is equivalent to 73%. The symmetrical radiation patterns in the y-z and x-z planes are obtained for the potential of pattern reconfigurable. An optimized UWB antenna is designed and simulated by ansoft-HFSS.
