<P>PROBLEM TO BE SOLVED: To provide a branch structure in a compact waveguide structural body having excellent transmission characteristics and a waveguide power distributing function. <P>SOLUTION: A second waveguide structural body 1 is overlapped and arranged at the end of a first waveguide structural body 2 so that the transmission direction of high-frequency signals becomes orthogonal, and coupling windows 3 are formed on each of waveguide walls of the overlapped site. A thin portion in which the distance between the wall surface on which the coupling window 3 is formed near the portion of overlapping the first and second waveguides 1 and the wall surface opposing this is smaller than the distance of the other portion is provided, and the waveguide structural body 1 is disposed so that the center in the transmission direction of the thin portion 5 in the second waveguide is deviated from the center of the coupling window. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
