Abstract
[Technical problem] A conventional dielectric waveguide input/output structure has a strength of coupling which is adjusted by a length of an input/output electrode. However, there is a limitation in an adjustable range of the coupling, which makes it impossible to have an input/output structure with wider bandwidth. [Solution to the technical problem] A dielectric waveguide input/output structure is provided, which comprises an input/output point provided near the center on one side of a bottom surface of a rectangular parallelepiped-shaped dielectric body, wherein an outer periphery of the dielectric body is covered with an electrically conductive film, except for an L-shaped lateral part extending along an edge of the bottom surface from opposite sides of the input/output point and for a surrounding part of the input/output point in a lateral surface with which the input/output point is in contact.
