The field of this invention is a method of routing the signal conductors over individual ground return "miniplanes", a method that leads to the elimination of the common ground return plane as a distinct component in certain printed circuits applications. The essential elements of this invention are: signal traces routed in a multilayered printed circuit directly over ground traces and individual ground return traces wide enough with respect to the signal traces to minimize electromagnetic field fringing effects. (Image Omitted) Applications for formed high frequency circuits employ the planar signal transmission system. The basic two models of this system are the "strip line" and "microstrip".
