Waveguides (43C, 43D) guide Z-polarized waves in a Y-direction. The input/output ends between the waveguide (43C) and the waveguide (43D) multiplex and output Z-polarized waves from the waveguides (43C, 43D), and input external Z-polarized waves to the waveguides (43C, 43D). A waveguide shift part (43A) has an end (43I) connected to an end (43F) of the waveguide (43C) and has an end (43J) which is shifted relative to the end (43I) in a Z-direction and at which vertically polarized waves are inputted/outputted along the Y-direction. A waveguide shift part (43B) has an end (43K) connected to an end (43H) of the waveguide (43D) and has an end (43L) which is shifted relative to the end (43K) in the Z-direction and at which vertically polarized waves are inputted/outputted along the Y-direction. The vibration direction of the electric field of the radio waves passing through the end (43J) rotates about an axis along an X-direction by 90 degrees, and the vibration direction of the electric field of the radio waves passing through the end (43L) rotates about an axis along the X-direction by 90 degrees in the same direction as the end (43J). |
