Abstract:
1. A coupler, comprising: a first line; and a second line which is broadside coupled to the first line in a first and a second section, wherein the coupler comprises a dielectric layer which is arranged between the first and the second line and has a first thickness in the first section and a second thickness in the second section as well as the second thickness is larger than the first thickness, the capacitance between the first and the second line per length unit of the first line is larger in the first section in comparison to the second section, and the first and the second line form a first turn, wherein the coupler comprises a first capacitor designed as a parallel plate capacitor and arranged in the first section, the first line is electrically connected to a first electrode of the first capacitor or a section of the first line forms the first electrode of the first capacitor, and the second line is electrically connected to a second electrode of the first capacitor or a section of the second line forms the second electrode of the first capacitor.
