  • Gregorian antenna system for shaped beam and multiple frequency use
    Patent number: 6795034
    Abstract: A method and system for shaped beam and multiple frequency use having a shaped main reflector, two feeds having separate and distinct frequency bands, a first shaped sub-reflector having a frequency selective surface and a second shaped sub-reflector. The first shaped sub-reflector has the electrical property of reflecting one frequency band and passing another. A second desired frequency band from the second feed passes through the tuned FSS surface of the first sub-reflector and reflects off the second sub-reflector towards the main reflector.
    Type: Grant

  • Sub-reflector for dual-reflector antenna system
    Patent number: 6628238
    Abstract: An antenna includes a feed generating a communication signal. A sub-reflector is positioned to reflect the communication's signal to form a sub-reflective signal. A main reflector is positioned to reflect the sub-reflective signal. The sub-reflector has an elliptical rim.
