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