Abstract
This paper presents an ultra wideband (UWB) planar stepped-fat dipole antenna. Comparing to conventional fat-dipole antennas, the novel antenna has stepped arms for impedance matching. The stepped arms make wideband impedance matching. A prototype antenna is designed for an ultra wideband ground penetrating radar (UWB-GPR). From EM simulations, dimensions of antennas are chosen for the better performance. For verification, the antenna is fabricated and measured. It is shown that return loss of the antenna between 0.5 GHz and 2.7 GHz is better than 10 dB.
