Abstract

A flat shielded cable comprising a plurality of parallel spaced-apart signal conductors in a first plane and a shield member in the form of a conductive ground plane facing the signal conductors and being positioned in a second plane, the shield member having preselected amounts of conductive material removed in the area opposite the signal conductors to form ground lines, which are parallel to the signal conductors to control the characteristic impedance of the cable, and also to form parallel, conductive shunting paths between the ground lines at predetermined intervals to correct for excessive attenuation caused by skewing of the signal conductors with respect to the ground lines.
