Abstract:
A dielectric waveguide device comprising:a dielectric substrate having two surfaces;a conductor layer formed on each of the two surfaces of the substrate;a plurality of rows of through conductors formed in the substrate connecting the two conductor layers, the through conductors in each row being spaced at intervals equal to or less than a half of a wavelength in a transmission direction of a signal transmitted in the waveguide device,wherein the plurality of rows of through conductors include a first group of two parallel rows forming a first waveguide line having a width d for transmitting the signal in a first direction, and a second group of three parallel rows forming second and third waveguide lines each having a width d for transmitting the signal in the first direction, an end of the first waveguide line being connected to an end of the second waveguide line and an end of the third waveguide line in a region partially enclosed by a third group of rows forming connection through conductors; andat least one power ratio-adjusting through conductor formed in the substrate, the power ratio-adjusting through conductor being disposed in one of the second and third waveguide lines between the parallel rows of through conductors forming the corresponding waveguide line.
