PROBLEM TO BE SOLVED: To solve the problem that the cost is high in a conventional magic T because an airtight work must be done for the surroundings by an adhesive or soldering after adjusting screws for E-port are electrically adjusted, and that an airtight must be done for the surroundings of a surface in which an E-port waveguide is connected to the magic T by an adhesive or soldering. SOLUTION: A matching board is made from cutting on a waveguide coupling section constituting the E-port and branch ports 1, 2 instead of matching screws for the E-port. The matching board is provided in the area matching with the ceiling position of the branch port. COPYRIGHT: (C)2005,JPO&NCIPI
