ABSTRACT:
A polarization separator for separating orthogonal polarization waves into a horizontal polarization wave component and a vertical polarization wave component is minimized in size. A metal pole in the form of a thin metal bar is disposed in a circular waveguide of a waveguide member into which the orthogonal polarization waves are introduced, and reflects the horizontal polarization wave component so that it is outputted through an output terminal formed in a circumferential wall of the waveguide member. Meanwhile, the vertical polarization wave component propagates in a substantially rectangular waveguide provided rearwardly of the metal pole and is outputted from another output terminal. Since the rectangular waveguide is formed in a cutoff structure for the horizontal polarization wave component, the reflection means can be formed from the metal pole in the form of a thin bar, and consequently, the polarization separator can be minimized.
