Dielectric waveguide comprised of a dielectric block and a dielectric plate sandwiching an input/output feeder line
View Patent ↗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.
1. A dielectric waveguide device employing an input/output structure for a dielectric waveguide comprising:
a rectangular-parallelepiped-shaped dielectric block;
a plate-shaped dielectric plate having a through hole extending through approximately a center thereof; and
a feeder line comprising a line-shaped electrically conductive foil sandwiched between the dielectric block and the dielectric plate,
wherein the dielectric block and the dielectric plate are coupled together to form the dielectric waveguide; and
wherein the dielectric waveguide block is covered by an electrical conductive layer.
2. An input/output structure of a dielectric waveguide, the dielectric waveguide comprising:
a rectangular-parallelepiped-shaped dielectric block,
a plate-shaped dielectric plate having a through-hole extending through approximately a center thereof, and
a feeder line comprising a line-shaped electrically conductive foil sandwiched between the dielectric block and the dielectric plate;
wherein the dielectric block and the dielectric plate are coupled together to form the dielectric waveguide; and
wherein the dielectric waveguide is covered by an electrical conductive layer.
3. The dielectric waveguide input/output structure as defined in claim 2 , wherein the feeder line has an approximately quarter wavelength open stub provided on each of opposite sides at a position spaced away from a distal end thereof by an approximately quarter wavelength.
4. The dielectric waveguide input/output structure as defined in claim 3 , wherein the distal end of the feeder line has a large width.
