Abstract

A new adaptive technique for steering the direction of minimum axial-ratio (< 1 dB) towards the reflected or jamming signal is proposed for GNSS antennas. It relies on simple, low-cost commercially-available circularly-polarized antenna elements without influencing their gain. Its performance is demonstrated using two different antenna geometries, with five different configurations. The measurements agree well with simulation and theoretical calculations. The technique allows a combined 1 dB axial-ratio beamwidth of up to 83°.
