  • Rotating screen dual reflector antenna
    Patent number: 7576701
    Abstract: A system for steering a beam includes a main reflector that receives a signal from a subreflector and reflects the signal in a reflection direction. A prism refracts the signal in a refraction direction. One or more motors adjust a relative orientation between the main reflector and the prism to change a relative orientation between the reflection direction and the refraction direction to steer a beam resulting from the signal.
