Abstract
A waveguide/strip line converter includes a waveguide and a multilayer substrate. A second end of the multilayer substrate is fixed to an opening of the waveguide. The multilayer substrate includes a plurality of dielectric layers to form a plurality of substrate faces. A top substrate face includes a strip line and a first short-circuiting metal pattern. First and second intermediate substrate faces include second and third short-circuiting metal patterns with openings, respectively. A matching element forming substrate face includes a matching element, which is electromagnetically coupled with the strip line. A waveguide passage extends through the openings between the strip line and the matching element. A cross sectional area of the opening is larger than that of the opening.
