  • Dual-band parabolic reflector microwave antenna systems
    Patent number: 11489259
    Abstract: Microwave antenna systems include a parabolic reflector antenna and a dual-band feed assembly. The dual-band feed assembly includes a coaxial waveguide structure and a sub-reflector. The coaxial waveguide structure includes a central waveguide and an outer waveguide that circumferentially surrounds the central waveguide. The sub-reflector is mounted proximate the distal end of the coaxial waveguide structure.
    Type: Grant

  • Variable beam width antenna systems
    Patent number: 10116060
    Abstract: A microwave antenna is operated in a first operating state during an alignment operation for the microwave antenna system where the microwave antenna is configured to have a first beam width. Subsequent to the alignment operation, the microwave antenna is operated in a second operating state where the beam of the microwave antenna is configured to have a second beam width that is narrower than the first beam width.

  • Low sidelobe reflector antenna
    Patent number: 8581795
    Abstract: A front feed reflector antenna with a dish reflector has a reflector focal length to reflector diameter ratio of less than 0.25. A wave guide is coupled to a proximal end of the dish reflector, projecting into the dish reflector along a longitudinal axis. A dielectric block is coupled to a distal end of the waveguide and a sub-reflector is coupled to a distal end of the dielectric block. A shield is coupled to the periphery of the dish reflector. The sub-reflector diameter is dimensioned to be 2.5 wavelengths or more of a desired operating frequency.
