PROBLEM TO BE SOLVED: To obtain a polarized wave separation circuit for improving the freedom of design.SOLUTION: The polarized wave separation circuit comprises: a first circular coaxial unit 7 in which a first circular coaxial terminal 1 for propagating a TE11 mode and a TE21 mode is provided at one end; a second circular coaxial unit 8 in which a second circular coaxial terminal 2 for propagating the TE11 mode and cutting off the TE21 mode is provided at one end; a third circular coaxial unit 10 connected between the other end of the first circular coaxial unit 7 and the other end of the second circular coaxial unit 8. The first circular coaxial unit 7, the second circular coaxial unit 8, and the third circular coaxial unit 10 have an inner conductor 4 and an outer conductor 3, the outer conductor 3 of the third circular coaxial unit 10 being provided with a coupling terminal 6 for coupling with the TE21 mode. Therefore, the coupling characteristic of the TE21 mode and the propagation characteristic of the TE11 mode can be selected from a plurality of combinations of diameters of the inner conductor 4 and the outer conductor 3, making it possible to increase the freedom of design. |
