ABSTRACT:
A linear-circular polarizer used for the transmission in the microwave band, which provides excellent impedance characteristics and stabilized cross polarization characteristics by having 1/4 wavelength phase plates and the inner surface of a circular waveguide made in one-piece for the purpose of cost and production step reduction. The linear-circular polarizer includes a pair of 1/4 wavelength phase plates of a specified width and height formed opposite to each other and symmetric with respect to the waveguides central axis. The 1/4 wavelength phase plates are formed on the inner surface of a circular waveguide at a closed end opposite to an end where a primary radiator is located.
