We generally categorize the approaches for ultra-wideband antenna arraydesign, and consequently propose simplified concepts for antenna arrays for ahigh-precision, ultra-wideband FMCW radar 2-D local positioning system toobtain robustness against multi path interference, perform angle of arrivalanalysis, as well as instantaneous heading estimation. We focus on low-costand mechanical robust, industrial-application ready antennas. The antennaarrays are optimized for operation in the 5 GHz to 8 GHz frequency range andare designed towards supporting full omnidirectional 360° as well aspartial half-plane direction of arrival estimation. Two different conceptsfor vehicle- as well as wall-mounted antenna array systems are proposed anddiscussed. We propose a wideband unidirectional bow-tie antenna array elementhaving 97% impedance and 37% pattern bandwidth and a robust vehiclemounted omnidirectional antenna element having more than 85% impedance andpattern bandwidth
