ABSTRACT:
A dielectric body 20 with a dielectric constant near that of air has a surface 18, a portion of a paraboloid of revolution about an axis 9--9. A layer 15 of electrically conducting material is shaped by surface 18 to the form of an antenna reflector for transmitting electromagnetic radiation, or for receiving electromagnetic radiation indicated by arrows 50. A mating body 30 covers conductive layer 15. Dielectric body 20 has a protrusion 17 that mates with a horn 40 at a specified position relative to conductive layer 15, with horn axis 8--8 perpendicular to paraboloid axis 9--9.
