Patent ID: 8866562

Claim:
A signal converter configured to convert a signal between a substrate and an hollow waveguide, comprising: the substrate including a first conductor layer formed on one face of a dielectric substrate, and a second conductor layer formed on another face of the dielectric substrate; a plurality of first conductors that penetrate the dielectric substrate and provide conduction between the first conductor layer and the second conductor layer; a dielectric waveguide formed by the dielectric substrate, the first and second conductor layers, a first array provided with one or more of the plurality of first conductors which is arranged along a signal direction of the dielectric waveguide on one side of the dielectric waveguide, and a second array provided with one or more of the plurality of first conductors which is arranged along the signal direction on another side of the dielectric waveguide, the first and second conductor layers being coupled on the one and other side of the dielectric waveguide via the first and second arrays respectively; a plurality of blocking conductors that penetrate the dielectric substrate and provide blocking of a signal in the dielectric waveguide; and a converter that converts the signal between the hollow waveguide and the dielectric waveguide; the converter including a conductor patch having a separator region between the conductor patch and the first conductor layer, with the conductor patch being disposed on the substrate within an aperture of the hollow waveguide, wherein a plurality of second conductors connect the conductor patch with the second conductor layer.
