Abstract:
A dual gridded reflector antenna assembly comprising:a front parabolic reflector;a back parabolic reflector positioned adjacent to and behind said front parabolic reflector such that the center point of said front and back parabolic reflectors define a center axis;a first source illuminating said front parabolic reflector, said first source positioned in front of said front and back parabolic reflectors at a first offset and rotated at a first angle with respect to the center axis; anda second source illuminating said back parabolic reflector, said second source positioned in front of said front and back parabolic reflectors at a second offset and rotated at a second angle with respect to the center axis such that said first and second sources define an antenna feed separation having an inclination angle with respect to north-south direction said inclination angle defined by the following equation: ##EQU2## wherein x is inclination angle, H1 and H2 are the first and second offsets, respectively, and z and y are the first and second rotated offset angles, respectively.
