Abstract : An improved antenna feed providing control of the plane of polarization especially useful with 'scanning with compensation' radar tracking. An input transducer is coupled to first and second output transducers whereby the output transducers transmit two pencil-beam radiation patterns which are squinted by equal but opposite angles with respect to the scan axis. During reception, however, a non-reciprocal coupling means provides for separate sensing of the return signals received by the first and second output means and converts the signal received by the second output means so that it is in quadrature relationship with the signal received by the first output means.
