Abstract (en)
[origin: WO2013189513A1] A directional coupler arrangement (100), comprising an air waveguide (101) and a dielectric waveguide (109) having a coupling slot (111), wherein the air waveguide (101) and the dielectric waveguide (109) are coupled by the coupling slot (111). A method for coupling a first waveguide to a second waveguide comprising forming a coupling slot in the first waveguide and arranging the coupling slot of the first waveguide inside the second waveguide is also disclosed. The directional coupler arrangement has improved insertion loss, directivity and operational bandwidth. It is robust against manufacturing tolerances.
