Abstract

Disclosed is an electrical connector in which the conductive and dielectric elements are arranged in a composite I-beam shaped geometry in which the conductive element is perpendicularly interposed between two parallel dielectric and ground plane elements. Low cross talk and controlled impedance are found to result from the use of this geometry.
