In a dielectric waveguide input/output structure for performing conversion from a dielectric waveguide through a microstrip to a coaxial line, the conversion is performed once to the microstrip line, and then to the coaxial line, resulting in a greater loss. Thus, there has been a problem that degradation in performance is unavoidable. Further, the microstrip (8a) is required to have a certain level or more of length, so reduction in size of the printed circuit board (8) is impossible. This has been an impediment to downsizing of the input/output structure. To solve the problems stated above, provided is an input/output structure for a dielectric waveguide, comprising a rectangular-parallelepiped-shaped dielectric block, a plate-shaped dielectric plate, and a feeder line comprising a line-shaped electrically conductive foil sandwiched between the dielectric block and the dielectric plate. |
