Injection moldable cone radiator sub-reflector assembly
First Claim
1. A cone radiator sub-reflector assembly for a reflector antenna with a sub-reflector supported by a waveguide, comprising:
- a unitary dielectric block;
a sub-reflector provided at a distal end of the unitary dielectric block;
a waveguide transition portion of the unitary dielectric block dimensioned to seat inside an end of the waveguide; and
a sub-reflector support portion of the unitary dielectric block supporting the sub-reflector,wherein the sub-reflector support portion and the waveguide transition portion each comprise at least one longitudinal rib and at least one longitudinal groove, wherein the at least one longitudinal rib and the at least one longitudinal groove of both the sub-reflector support portion and the waveguide transition portion are coaxial with a longitudinal axis of the unitary dielectric block, and wherein the at least one longitudinal groove of the sub-reflector support portion and the at least one longitudinal groove of the waveguide transition portion are open to a proximal end of the unitary dielectric block, and wherein a leading edge of each of the at least one longitudinal rib of the sub-reflector support portion is angled, forming a conical surface profile with a maximum diameter toward a distal end of the unitary dielectric block.

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 insertion coupling into an end of the waveguide. A sub-reflector support portion of the dielectric block and the waveguide transition portion provided with a plurality of longitudinal ribs and grooves coaxial with a longitudinal axis of the assembly; the longitudinal grooves open to a proximal end of the dielectric block. The unitary dielectric block may be manufactured as a single contiguous monolithic portion of dielectric material via injection molding.
