Abstract (en)
[origin: EP1303001A1] A directional coupler has a substrate and two first terminals (1,2) arranged on the substrate and connected by a first line (11) and two second terminals (3,4) connected by a second line (12) in which the lines (11,12) run through a coupling zone. The lines (11,12) are spaced in the coupling zone by a conductor surface (20) un-connected with the lines.
