Abstract
A waveguide system for a transition between a waveguide structure having an exterior stripline element and a waveguide structure having a stripline element which is completely shielded. To that end, the present invention provides a transition which is able to be realized particularly easily and efficiently with the aid of a multilayer printed circuit board architecture.
Claims10
A waveguide system, comprising:
- a first waveguide structure having a first electroconductive stripline element, which is disposed in a first direction in space between two electroconductive planes;
- a second waveguide structure having a second electroconductive stripline element, which is disposed in the first direction in space above an electroconductive plane, and which in a second direction in space, is surrounded by two electroconductive edge elements, the second direction in space running perpendicular to the first direction in space;
- and
- a transition area, which is situated spatially between the first waveguide structure and the second waveguide structure, the first stripline element and the second stripline element each projecting into the transition area, and the second stripline element being situated along the first direction in space above the first stripline element.
