ABSTRACT:
A broad band phase shifting system, having a fixed angle of phase retardation, has at least one broad band reflecting means in the system. The broad band reflecting means also has an angle of phase retardation, with the angle of phase retardation of the reflecting means less than the fixed angle of phase retardation of the system.
