Abstract
A polarization separating filter, which can be integrated into a planar hollow waveguide circuit, is comprised of a central hollow waveguide ( ), in which two orthogonal, linearly polarized waves can be propagated, where one end of the central hollow waveguide ( ) is closed by a short circuit wall ( ) and in the vicinity of the short circuit wall ( ), two waveguides ( ) are coupled to two opposing walls of the central hollow waveguide ( ), in an at least approximately identical cross sectional plane extending perpendicular to the longitudinal axis of the hollow waveguide. The hollow waveguides ( ) coupled at the end of the central hollow waveguide ( ) are rotated in relation to each other in terms of their cross sections so that the fields in them are oriented orthogonally to each other.
