WIDEBAND AND LOW-LOSS QUADRATURE PHASE QUAD-FEEDING NETWORK FOR HIGH-PERFORMANCE GNSS ANTENNA

摘要

A system and method for a wide-band low loss quadrature phase antenna feedsystemis provided. A 180° phase shifter is configured to generate a 0°and 180° phase output. Thephase shifter's outputs are fed into a 90° hybrid coupler to generate0°, 90°, 180° and 270°outputs for used to feed a quadrature phase antenna.
