Abstract :
In this paper a compact dual-polarized Ultra Wideband antenna applicable to an indoor radar is presented. Apart from a broad bandwidth, which is between 3.5 to 13.5 GHz, the main features are high polarization purity and small dimensions. The compact size is determined by the embedding in a dielectric (Teflon). The antenna itself is tapered slot lines based, typically known as Vivaldi antennas. Additionally to the description of the design also measurement results of a prototype are presented.
