Abstract
In one example embodiment, a coplanar waveguide signal transition element transitions high-speed signals between vertically stacked coplanar waveguide transmission lines. The signal transition element comprises one or more dielectric layers and a plurality of electrically conductive vias extending through at least a portion of the one or more dielectric layers. The vias include one or more signal vias and one or more ground vias that are configured to transition signals between the vertically stacked coplanar waveguide transmission lines. The signal transition element also comprises a ground plane disposed within the one or more dielectric layers and electrically coupled to the one or more ground vias. The ground plane has one or more openings through which the one or more signal vias respectively pass.
