ABSTRACT:
On a terminal end plane of a circular waveguide, metal columnar blocks and a cross shaped branching transforming unit for branching two orthogonal linear polarized waves and transforming from circular TE.sub.11 mode to rectangular TE.sub.10 mode are disposed, and two rectangular waveguides are composed so as to form an angle of 45 degrees to the vertical axis and horizontal axis, that is, symmetrically to the axial center of the circular waveguide, in an electric field direction of the first linear polarized wave and an electric field direction of the second linear polarized wave. In this constitution, the orthogonal polarized wave branching filter of the microwave band for satellite communications can be reduced in size, and moreover the principal components can be formed integrally by an injection molding process.
