Abstract :
A parametric study of the constraints related to Gregorian/Cassegrain offset reflectors having negligible cross polarization was undertaken with the aid of design equations linking the defining parameters of the primary reflectors to those of the secondary reflectors. This study resulted in the mapping of a very large number of Gregorian/Cassegrain offset reflectors having negligible cross polarization. The domains of definition of the equations derived are deduced from geometrical considerations. Physical insights into the above constraints are presented
