In this paper, a UWB antenna with an enhanced bandwidth is proposed. The enhanced ultra wide band (UWB)
antenna consists of a rectangular patch fed by a 50 Ω microstrip feed line and partial ground plane. The bandwidth
enhancement is achieved by making three modifications on the partial ground plane; adding two rectangular
sleeves, adding one rectangular groove and adding two rectangular slots. The characteristics of this antenna are
investigated using high frequency structure simulator (HFSS). The proposed design achieves large bandwidth at
return loss RL ≥ 10 dB of (3.4- 22.4) GHz (147.29%). Promising peak gain with good impedance matching and
omni-directional radiation pattern are obtained.
