Summary:The invention provides a dielectric waveguide comprising dielectric body having an exterior coated with an electrically conductive film. Region in one side surface couples to another dielectric waveguide, and slot in bottom surface exposes the dielectric body in an L-shape in two adjacent side surfaces, except for the one side surface. Front surface of printed circuit board has a ground pattern opposed to the slot, which includes opening with outer shape greater than slot, and a back surface having a ground pattern surrounding a strip line disposed to cross through the slot. A distal end of the strip line and the front surface-side ground pattern are coupled together by a via hole. The opening is surrounded by a via hole group which couples the front and the back surface-side ground patterns together. The dielectric waveguide is disposed to allow the opening and the slot to be opposed to each other. 本发明提供种电介质波导管的输入输出连接构造。以往的构造存在问题：耦合的大小存在极限，难以获得宽频带的特性。电介质波导管包括用导体膜覆盖外壳而成的电介质，在其侧面具有用于与其他电介质波导管连接的耦合部，在其底面具有与除了侧面
