Abstract (en)
[origin: WO2009000431A1] A directional coupler for directed transmission of radio-frequency signals has at least three lines (16, 18, 19) and at least three connections (11, 12, 13, 14). Two lines (18, 19) of the three lines (16, 18, 19) are conductively connected at least at their ends. A third line (16) is arranged between the two first lines (18, 19) and is electromagnetically coupled to them. In this case, the radio-frequency signal is transmitted from the third line (16) to the first line (18) and the second line (19). The coupling takes place via a coupling gap.
