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