Abstract:
1. A substrate with a line, the substrate comprising: a plurality of dielectric layers; and a plurality of metallization planes arranged between the dielectric layers so that the substrate has a multiple layer construction; wherein the plurality of metallization planes include a line embedded in the substrate, the line including a strip-shaped signal conductor arranged between a first ground plane and a second ground plane and separated from each of the first and second ground planes by at least one of the dielectric layers, wherein one of the first and second ground planes has a slot therein that follows a profile of the signal conductor, wherein, in the slotted ground plane, the slot is expanded at one position into a recess, and wherein a feedthrough extends through the recess and connects the signal conductor electrically to a structure that is arranged at another of the plurality of metallization planes of the substrate.
