Abstract

A device includes at least one electrically conductive structure and at least one stripline. The stripline includes stripline sections that are connected to one another in a series connection between a first terminal and a second terminal. A first subset of the stripline sections is arranged on a first side of the conductive structure and a second subset of the stripline sections is arranged on a second side of the conductive structure. The device also includes at least one conductive connection between the first subset of the stripline sections and the second subset of the stripline sections, wherein the at least one conductive connection is isolated from the at least one electrically conductive structure.
