Abstract

A device including a capacitor system for varying the impedance of a section of a coplanar waveguide. The capacitance of the capacitor system is variable. The capacitor system includes a first electrically conductive connection, a second electrically conductive connection, and a third electrically conductive connection at least partially. The signal line of the section of the waveguide is interrupted over a predetermined length, the first connection connecting the ground lines of the waveguide, the second connection connecting the ground lines of the waveguide, and the third connection connecting the two parts of the interrupted signal line.
