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.

Abstract: The present invention provides a dielectric waveguide resonator comprising a pair of rectangular parallelepiped-shaped dielectric blocks being in contact with each other through respective contact surfaces thereof. The dielectric waveguide resonator has an outer periphery coated with an electrically conductive film except for the contact surfaces, and is configured to resonate in a TE mode. A probe composed of an electrically conductive film is formed on at least one of the contact surface. Thus, it becomes possible to provide a dielectric waveguide resonator having a simple structure, requiring no adjustment structure, and comprising a structure for conversion between a dielectric waveguide and a coaxial line.

Abstract: 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.

Abstract: The present invention provides a waveguide slot antenna which utilizes a waveguide as a feeding line and has a linear-shaped slot provided in a wall of the waveguide. The waveguide slot antenna is characterized in that it comprises a pair of polarized wave conversion members surrounding an outer periphery of the slot and divided by a slit intersecting the slot. The present invention can provide a waveguide slot antenna capable of radiating a circularly polarized wave with a satisfactory axial ratio characteristic, over a wide band, only by adding a simple component to a conventional waveguide slot antenna.
