Abstract

This paper presents an assessment of the impact of feeding geometry and leakage current on the performance of several types of printed elliptical UWB dipoles. Using simulation and experimental verification this paper investigates the impact via field analysis, S-parameters, and pulse transmission. The UWB dipoles investigated are; a microstrip-fed UWB dipole, that had unpredictable behaviour due to the feed, which excited leakage current down the feed cable and, as a result, distorted the pulse. To minimise the leakage current, three other UWB dipoles were investigated. These were a CPW-fed UWB dipole with slots, a hybrid-feed UWB dipole, and a tapered-feed UWB dipole.
