Abstract
The practical challenge in locating the focal point of an offset reflector is addressed through the use of vectorial secondary radiation patterns of the parabolic offset reflector, when the primary feeds are axially defocused. Moreover, a more general case is investigated when the feed is rotationally misaligned along the symmetry plane of the offset reflector geometry.
