Abstract

In this paper, a two element antipodal Vivaldi antenna array in combination with an ultra-wideband (UWB) Wilkinson power divider feeding network is presented. The antennas are placed in a stacked configuration to provide more gain and to limit cross talk between transmit and receive antennas in radar applications. Each part can be realized with standard planar technology. For a single antenna element, a comparison in performance is done between standard FR4 and a Rogers^® RO3003 substrate. The antenna spacing is obtained using the parametric optimizer of CST MWS^®. The performance of the power divider and the antenna array is analyzed by means of simulations and measurements.
