PROBLEM TO BE SOLVED: To provide coupling structure between the laminated waveguide line and a microstrip line, between the laminated waveguide line and a coplaner line or between the laminated waveguide lines that is easily manufactured by a known multi-layer processing technology. SOLUTION: The coupling structure is a structure to couple a laminated waveguide line 10 provided with a couple of main conductors 2, 3 formed in parallel with a dielectric materil inbetween and two rows of via-hole groups 4 placed at an interval between a cut-off wavelength or below to connect electrically the main conductor layers 2, 3 electrically in a signal transmission direction with other signal transmission line 5 such as a microstrip line, a coplaner line or a laminated waveguide line, a transmission via-hole 6 is extended from an end of the other signal transmission line 5, the other end of the transmission viahole 6 is inserted to the laminated waveguide line 10 and the transmission via-hole is acted as a monopole antenna. |
