Abstract
A hollow-waveguide-to-planar-waveguide transition circuit includes: a dielectric substrate; strip conductors formed on a first main surface of the dielectric substrate; a ground conductor formed on a second main surface of the dielectric substrate, facing the strip conductors in the thickness direction; a slot formed in the ground conductor; a coupling conductor formed at a position to be electrically coupled with the strip conductors on the first main surface; and branch conductor lines formed on the first main surface. Each of the branch conductor lines includes a base portion branching from the coupling conductor and a tip portion that is electrically open.
