<P>PROBLEM TO BE SOLVED: To obtain a polarization coupler which is assured of the ease of septum plate adjustment and processability to obtain desired electrical characteristics. <P>SOLUTION: A polarization coupler comprises: a connection waveguide, which is disposed in the axial direction of a circular waveguide and connects a rectangular waveguide having a short side shorter than the inside diameter of a circular waveguide with the circular waveguide; a tabular conductor wall which is formed throughout the connection waveguide and the circular waveguide, and divides the insides of the circular waveguide and the connection waveguide disposed in parallel to a direction in which the long side of the rectangular waveguide extends; a first inclined plane which is formed on the inner wall of the connection waveguide at a position opposed to the one face of the conductor wall, and which is inclined toward the conductor wall side as it goes toward the rectangular waveguide side; a second inclined plane which is formed on the inner wall of the connection waveguide at a position opposed to the other face of the conductor wall, and which is inclined toward the conductor wall side as it goes toward the rectangular waveguide side; and a coupling hole which is formed in the circular waveguide, and extracts an electromagnetic wave which has been polarized by the conductor wall from electromagnetic waves propagated by the circular waveguide . <P>COPYRIGHT: (C)2013,JPO&INPIT |
