Abstract:
1. A cone radiator sub-reflector assembly for a reflector antenna with a waveguide supported sub-reflector, comprising: a unitary dielectric block; a sub-reflector provided at a distal end of the dielectric block; a waveguide transition portion of the dielectric block dimensioned for insertion coupling into an end of the waveguide; a sub-reflector support portion of the dielectric block; a dielectric radiator portion between the waveguide transition portion and the sub-reflector support portion; an outer diameter of the dielectric radiator portion provided with a plurality of radially inward grooves; and a lens bore extending from a proximal end of the dielectric block towards the distal end of the dielectric block at least to the sub-reflector support portion; the radially inward grooves extending radially inward to a diameter less than an inner diameter of the end of the waveguide; a maximum material thickness of the unitary dielectric block occurs between a sidewall of one of the radially inward grooves and the sub-reflector.
