Abstract : A microwave circular polarizer having two matched waveguide arms with a first arm having a twist in a first rotional sense and with a second arm having a twist in a second (reverse) rotational sense, and a hybrid coupler receiving radiation signals from the two arms. A left-hand 45 deg twist in one arm and a right-hand 45 deg twist in the other arm ensure that orthogonal linearly polarized components of an incident radiation field are combined in the hybrid coupler so as to direct a right circularly polarized signal out of one of the remaining ports of the hybrid coupler, and to direct a left circularly polarized signal from the other remaining port of the hybrid coupler. (Patent Application)
