An improved design of Ultra Wide Band(UWB) Bow-Tie antenna is presented. The UWB antenna is composed of an electromagnetically coupled Bow-Tie patch and a parasitic ground patch, whose working frequency is extended to full UWB range by this work. The antenna is fabricated on RF-60A substrate with t=0.64 mm, r=6.15 and tan=0.0025. All the parameters are precisely calculated by an adequate optimization method. The proposed design gives the full range operation, which is verified by measurement.
