ABSTRACT:
A polarizer has a plurality of short waveguide sections arranged so that rectangular-shaped sections alternate with circular-shaped sections. The two end sections are both circular. The rectangular sections have a minimum size at least as large as the minimum diameter of the circular sections. The size of the rectangular sections progressively changes from section to section with all sections of the polarizer being symmetrical about the centre point of the polarizer. The length of each section is less than half a wavelength at maximum operating frequency. The structure of the polarizer is simple and straightforward so that computer-aided analysis and design methods can easily be used. The polarizer has a relatively large bandwidth and can interface directly with corrugated circular waveguides.
