Abstract

A UWB antenna, which is adopted from a Ground Penetrating Radar (GPR) antenna, is proposed for impulse radio applications. The proposed antenna has dimensions of 7 cm by 1.5 cm and is based on a modified bow-tie structure. It employs improved resistive loading for transmission of 0.2-ns monocycles with minimal ringing. The antenna radiation efficiency is enhanced by some discontinuities in the antenna that serve as secondary sources of radiation. Theoretically, it has been found that antenna ringing is adequately suppressed after less than 3 times the pulse duration. This will set the potential limit of data rate at more than 1 Gbit/s. Furthermore, the antenna is omni-directional, has stable radiation patterns, and shows a relatively flat gain in the 3-10 GHz frequency range. Experimentally, it has been found that within this bandwidth its input impedance is relatively flat and assumes values of around 100 Ohms.
