  • Autotracking antenna system
    Patent number: 5841397
    Abstract: An autotracking antenna system operable to cause a steerable antenna assembly to automatically track a moving RF video signal source has a reflector, a rotator for positioning the reflector at any desired position in azimuth and elevation, a primary antenna element positioned to receive an RF video signal reflected from the center of the reflector, and a series of offset antenna elements each positioned to receive an RF video signal reflected from a different off-center location on the reflector. A tracking control processor is operable to select and receive video signals from the primary antenna element and the offset antenna elements and to control the rotator, and a signal receiver receives video signals from the antenna element and has a video signal output.
