Equalized offset fed east and west shaped reflectors (12) and (14) and technique for producing the same are provided herein. A first shaped reflector (12) has a first shaped reflective surface (3) formed to provide a first shaped beam radiation pattern (22). Dimensional deviations such as deviations (X) and (Y) are measured between the first shaped reflective surface (13) and a parent surface (30). A second shaped reflector (14) is formed with a shaped reflective surface (15) which has dimensional deviations superimposed on the other side of the parent surface (30). The second shaped reflector (12) is rotated 180 degrees relative to the first shaped reflector (14). The first and second shaped reflectors (12) and (14) are then placed in a configuration opposite one another and have shaped beam radiation patterns (22) and (24) which are substantially equal to one another. In addition, feed horns (18) and (20) are operatively coupled to the first and second shaped reflective surfaces (13) and (15) respectively.
A method for forming a second shaped reflector having far field beam characteristics substantially equal and opposite to a first shaped reflector, the first shaped reflector having dimensional deviations with respect to a first side of a substantially symmetrical parent surface, the method comprising:
A method for forming a second shaped electromagnetic radiation reflector for use in a spacecraft communications antenna system having far field electromagnetic radiation beam characteristics substantially equal and opposite to a first shaped spacecraft communications antenna system reflector, the first shaped reflector having dimensional deviations with respect to a first side of a substantially symmetrical parent surface and having a radiation pattern defined with respect to one side of a focal axis, the method comprising:
