Abstract
A feed assembly for a reflector antenna having a unitary portion of dielectric material, a proximal end of the unitary portion configured for connection with the reflector antenna. The unitary portion having a waveguide portion extending between the proximal end and a sub reflector support having a sub reflector surface at a distal end. The waveguide portion and the sub reflector surface covered with an RF reflective material. The unitary portion may be cost effectively formed via, for example injection molding and or machining. Alternatively, the feed assembly may be formed as a horn feed, without a sub reflector.

A feed assembly for a reflector antenna, comprising:
- a unitary portion of dielectric material, a proximal end of the unitary portion configured for connection with the reflector antenna,
- the unitary portion having a waveguide portion extending between the proximal end and a sub reflector support having a sub reflector surface at a distal end;
- the waveguide portion and the sub reflector surface covered with an RF reflective material.
A method for manufacturing a feed assembly for a reflector antenna, comprising the steps of:
- forming a unitary portion of dielectric material, the unitary portion having a waveguide portion extending between a proximal end and a sub reflector support having a sub reflector surface at a distal end;
- and
- covering waveguide portion and the sub reflector surface with an RF reflective material.
A feed assembly, comprising:
- a unitary portion of dielectric material having a proximal end and a distal end, the unitary portion having a waveguide portion extending between the proximal end and a plurality of progressively larger diameter concentric steps at the distal end;
- an outer surface coated area of the waveguide portion and the concentric steps covered with an RF reflective material.
