POLARIZATION SEPARATOR AND WAVE-GUIDE-MICROSTRIP LINE MODE TRANSFORMER FOR MICROWAVE APPARATUS.

摘要

A polarization separator for separating orthogonal polarization waves (H,V) into a horizontal polarization wave component (H) and a vertical polarization wave component (V) is minimized in size. A metal pole in the form of a thin metal bar (8) is disposed in a circular waveguide (4) of a waveguide member (1) into which the orthogonal polarization waves are introduced, and reflects the horizontal polarization wave component so that it is outputted through an output terminal (5) 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 (15). 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.
