ABSTRACT:
An antenna fabrication scheme for shaped reflectors analyzes the geometry of the shaped reflector to be fabricated. On the basis of this analysis, a surface of revolution which closely approximates the shaped reflector is defined. The axis of revolution of the generated surface can then be employed by a single reflector shaping tool to describe the surface of revolution a portion of which approximates that of the desired shaped reflector. The shaped reflector is then effectively removed from the described surface by defining the perimeter of the shaped reflector on the surface of revolution.
