Abstract
A movable waveguide block 50 having transmission lines 51 and 52 slides in a non-contact manner between a first end surface 30b of a first fixing waveguide block 30 having transmission lines 31 and 32 and a second end surface 40a of a second fixing waveguide block 40 having a transmission line 41, and switching of propagation paths is performed. Grooves 35A, 35B, 36A, 36B, 45A, 45B, 55A, 55B, 56A, 56B, 57A, 57B, 58A, and 58B having depths equivalent to ¼ of a guide wavelength of an electromagnetic wave of a leakage prevention object are provided in pairs around openings of the transmission lines 31, 32, 41, 51, and 52 facing each other across a gap between blocks. Accordingly, unintended leakage of electromagnetic waves to the transmission lines via the gap between the blocks is prevented, and isolation increases.
