ABSTRACT:
Signal degradation is minimized in an electronic polarizer of the type having a circular input waveguide, rectangular output waveguide and an intermediate electromagnetic coil. A ferrite core is contained between impedance matching transformers within a small diameter intermediate waveguide section and air gaps are minimized by ferro-magnetic washers pressed onto the intermediate waveguide to hold the transformers in close contact with the ferrite core ends. The washers also support the electromagnetic coil coaxially within the cylindrical input waveguide, enhance the efficiency of the coil and define the transition walls between the small intermediate waveguide and the larger input and output waveguides.
