Abstract
An antenna reflector is disclosed having a laminated reflector surface bonded to a rigid molded support structure. The reflector surface is thermoformable and has at least one metallized layer that is "sandwiched" between two plastic layers. The forming of the antenna reflector is accomplished in a single molding operation.
Claims1
Antenna reflector comprising:
- (I) a thermoformable laminate material having at least one reflective metallic layer disposed between two plastic layers, and
- (II) a support structure molded onto said laminated reflector, wherein:
- (a) one of said two plastic layers comprises a plastic film,
- (b) said one reflective metallic layer comprises a reflective metallic layer deposited on said plastic film,
- (c) the other of said two plastic layers comprises a plastic support layer bonded to said metallic layer, and
- (d) said reflector is generally parabolically shaped with a ratio of focal length divided by diameter (f/d) of not less than about 0.4 so as to reduce stress in said reflective metallic layer.
