Abstract :
Ultra-wideband (UWB) technology promises interesting perspectives for short range sensing. This paper presents UWB antennas that are used by an autonomous operating robot in order to demonstrate different localization, object identification and imaging applications in real scenarios. As the different algorithms need special antenna solutions, three types of UWB antennas are developed. Two of them are dual-polarized to allow the use of polarization diversity. Further, the antennas differ in radiation pattern and location of the phase center in order to meet the requirements given by the manifold applications. The used frequency band covers 3.5 to 10.5 GHz.
