    • PROBLEM TO BE SOLVED: To provide a compact interfacing device for rotating electro-magnetic fields between an input waveguide and an output waveguide.SOLUTION: A compact interfacing device for rotating electro-magnetic fields between an input waveguide and an output waveguide comprises: a support bar extending between opposing sides of a frame; the frame encircling an interior space divided by the support bar; and a dipole bar orientated orthogonally to the support bar. When the input waveguide interfaces an input-side of the frame and is arranged such that an extent of an input width of the input waveguide is orientated at a first angle with respect to an extent of the dipole-bar length, and when the output waveguide interfaces an output-side of the frame and is arranged such that an extent of an output width of the output waveguide is orientated at a second angle with respect to the extent of the dipole-bar length, an input electric field aligned perpendicularly to the extent of the input width is rotated upon propagating through the compact interfacing device.

    • PURPOSE:To switch the plane of polarization without a mechanical movable part, by dividing an incident electric field into two by a partitioning plate provided in a rectangular waveguide and synthesizing divided fields after shifting the phase of one at 180 deg. by a phase shifter. CONSTITUTION:The electric field incident to a rectangular waveguide 21 is divided into two fields of the same direction and the same magnitude because this field is perpendicular to a metallic plate 17. One of divided fieds has the phase shifted at 180 deg. for the other by a phase shifter 16 controlled electrically. Fields which enter to a rectangular waveguide 14 are perpendicular to the metallic plate 14 and have directions opposite to each other and have the same magnitude. The height of the metallic plate 14 is tapered. Two fields go from the metallic plate 14 toward a side plate 15 and an upper plate 14 of the rectangular waveguide 14. Components of two fields toward the upper plate 14 are increased according as the height becomes lower, and finally, all components of them go up from below.
