Abstract:
1. A method for producing a coplanar waveguide system on a substrate for the transmission of electromagnetic waves, the method comprising: providing the coplanar waveguide system that includes a signal conductor and at least two grounding conductors on a predefined area of the substrate; forming a first dielectric insulating layer over the signal conductor and the at least two grounding conductors of the coplanar waveguide system; back-etching of an area of the substrate below the coplanar waveguide system such that the signal conductor of the coplanar waveguide system is supported completely and each of the at least two grounding conductors are supported at least partially by embedment in the first dielectric insulating layer; and structured metallization of the surface of the back-etched area of the substrate and of a lower surfaces of the signal conductor and of at least a portion of lower surfaces of the at least two grounding conductors and of the coplanar waveguide system, which are located above the back-etched area, thereby forming the signal conductor with an increased thickness and said at least two grounding conductors at least partially thickened.
