PROBLEM TO BE SOLVED: To provide a connection structure for rectangular waveguide such that two rectangular waveguides can be connected directly to each other so that directions of waveguide axes and a magnetic field are orthogonal to each other.SOLUTION: A first rectangular waveguide 1a has a first rectangular opening 4, which has substantially the same size as a connection end opening of a second rectangular waveguide 2 formed in one wide wall surface on one length-directional end side where a short-circuit surface 3 is formed, to have a short side of the first rectangular opening 4 orthogonally to a narrow wall surface of the first rectangular waveguide 1a, and also has a second rectangular opening 5, which has substantially the same sectional size as the second rectangular waveguide 2 and to which a third rectangular waveguide 6 having a short-circuit surface 7 at one end has the other end opening end connected, formed at a position of the other wide wall surface opposed to the first rectangular opening 4 to have a short side of the second rectangular opening 5 orthogonally to the narrow wall surface of the first rectangular waveguide 1a. |
