Claim Text:
1. An antenna feed system comprising: a phase shifter configured to accept an electronic signal as an input and configured to generate output signals having a 0° and 180° phase, wherein the phase shifter comprises a first microstrip region, a first parallel strip line region, a phase reversal region, a second parallel strip line region and a second microstrip region and wherein the phase reversal region comprises a plurality of vias that connect a first conductor located on a first side of a substrate with a second conductor located on a second side of the substrate; and a first hybrid coupler configured to accept the 0° output from the phase shifter and generate a 0° and a 90° phase output; a second hybrid coupler configured to accept the 180° phase output and generate a 180° and a 270° output; a reference path operatively interconnected with the phase shifter.
