Title:

CONTROLLED ILLUMINATION DIELECTRIC CONE RADIATOR FOR REFLECTOR ANTENNA

Document Type and Number:

WIPO Patent Application WO/2013/032556

Kind Code:

A3

Abstract:

A dielectric cone radiator sub-reflector assembly for a reflector antenna with a waveguide supported sub-reflector is provided as a unitary dielectric block with a sub-reflector at a distal end. A waveguide transition portion of the dielectric block is dimensioned for coupling to an end of the waveguide. A dielectric radiator portion is provided between the waveguide transition portion and a sub-reflector support portion. An outer diameter of the dielectric radiator portion is provided with a plurality of radial inward grooves and a minimum diameter of the dielectric radiator portion is greater than 3/5 of a sub-reflector diameter of the sub-reflector support surface.
