Abstract
The invention provides a coupling device between a metal wave guide (three dimensional system) and an electronic signal processing circuit (two dimensional system). The transition is provided by means of a dielectric wave guide introduced longitudinally into the metal wave guide. A chamfer cut in the dielectric guide concentrates the energy of the input signal on a face of the dielectric bar, at the interface with another dielectric material (isolated image guide). At this interface, a microstrip line transmits the energy to a semiconductor component.
