ABSTRACT:
A reflectarray antenna includes a primary feed that radiates a primary wave to a plurality of radiators where the wave is absorbed. A portion of the absorbed wave is resolved into first and second mutually orthogonal components at first and second feed ports, respectively, of a radiator. The first component is transmitted with a designated phase shift via a transmission phase shifter to the second feed port. Correspondingly, the second component is transmitted with the designated phase shift via the phase shifter to the first feed port. After the components are transmitted to the feed ports, they are re-radiated by the radiator in polarization states orthogonal to the ones in which they were absorbed.
