First Claim
1. A dielectric-waveguide-type transmission line comprising:
- a dielectric substrate having two opposed main surfaces;
a plurality of protrusions aligned, one after another, on at least one main surface of the dielectric substrate;
electrodes formed on both main surfaces of the dielectric substrate and on outer surfaces of the protrusions;

Abstract
In a transmission line, protrusions extend in line one after another in a direction perpendicular to the cross section in a part of a dielectric substrate, with a discontinuous portion therebetween. A lower-surface electrode is formed on a main surface of the dielectric substrate provided with the protrusions and on the outer surfaces of the protrusions. An upper-surface electrode is formed on substantially the whole area of the surface opposite to the lower-surface electrode. Further, a plurality of through-holes for connecting the lower-surface electrode and the upper-surface electrode, which are formed on both surfaces of the dielectric substrate, are aligned on both sides of the protrusions along the direction in which the protrusions extend. Also, coplanar lines and a circuit element are mounted on the upper-surface electrode. The coplanar lines are coupled at a predetermined position to a transmission path formed by the protrusions.
