Abstract (en)
[origin: WO0128030A1] The invention relates to a directional coupler for electromagnetic waves comprising an injection path (3) and three decoupling paths (4, 5, 11), which are linked to each other by means of coupling arms (6, 7a - 7e), whereby a first decoupling path (4) is connected to the injection path (3) by means of a first series arm (6), a second decoupling path (5) is connected to a third decoupling path (11) by means of a second series arm (16) and the first series arm (6) is connected with the second series arm (16) by means of shunt arms (7a - 7e). The shunt arms (7a - 7e) are arranged in five consecutive groups, each comprising at least one shunt arm, starting at the injection path (3) and are alternately high impedance groups (7a, 7c, 7e) and low impedance groups ( 7b, 7d) whereby the group (7a) adjacent to the injection path (3) is a high impedance group.
