Abstract
A polarizer for a dual frequency band is formed of square waveguides of a dual structure. A section is formed which extends in a step-like manner as deeper inside between outer and inner square waveguides. The section is connected to the inner square waveguide at an output portion. A third section protrudes from the sidewall of the inner square waveguide, which section extends in a step-like manner as deeper inside and connected to the other sidewall of the square waveguide at the output portion to provide two divided rectangular waveguides.
