Polarized signal receiver system

A polarized signal receiver comprising:

• a first waveguide for transmitting polarized signals;
• a circular waveguide for receiving polarized signals at one end and coupled to the first waveguide at the other end, said other end having a rear wall;
• an insulator rod, rotatably mounted through said other end of the circular waveguide;
• signal conducting means, fixedly mounted in the insulator rod concentric with the axis of rotation thereof having a receiver probe portion oriented in the circular waveguide orthogonal to the axis of said circular waveguide for receiving one polarization of the incident signal, a launch probe portion concentric with the insulator rod and extending into the first waveguide for launching said signal therein, and a transmission line portion, having a first section contoured to the inside surface of the circular wall, and substantially parallel to the axis, of the circular waveguide, and having a second section contoured to the inside surface, and substantially parallel to the plane, of the rear wall of the circular waveguide, for connecting the receiver probe portion to the launch probe portion;
• and
• transformation means intermediate the incoming signals and the signal conducting means for transforming circularly polarized signals to linearly polarized signals.
