Abstract
The invention relates to a device for guiding electromagnetic waves from a wave guide (10), in particular a multi-band wave guide, to a transmission line (20), in particular a micro strip line, arranged at one end of the wave guide (10), comprising coupling means (30-1, . . . , 30-7) for mechanical fixation and impedance matching between the wave guide (10) and the transmission line (20). It is the object of the invention to improve such a structure in the way that manufacturing is made easier and less expensive than according to prior art. According to the present invention that object is solved in the way that the coupling means comprises at least one dielectric layer (30) being mechanically connected with the main plane of the transmission line, the geometric dimension of that at least one dielectric layer extending along the propagation direction of the electromagnetic waves being correlated with the center frequency of electromagnetic waves in order to achieve optimised impedance matching.
