Claim Text:
1. A high speed transmission cable comprising a first conductor set including one or more inner conductors defining a longitudinal axis of the transmission cable; a first dielectric film comprising a first base layer having a plurality of first protrusions formed on a first major surface of the first base layer, the first dielectric film having first and second longitudinal edges aligned with the first conductor set; wherein the first dielectric film is disposed such that the first base layer is partially concentric with the first conductor set and wherein a portion of the first protrusions is disposed between the first conductor set and the first base layer in a region where the first base layer is concentric with the first conductor set; a second dielectric film comprising a second base layer having a plurality of second protrusions formed on a first major surface of the second base layer, the second dielectric film having first and second longitudinal edges aligned with the first conductor set; wherein the second dielectric film is disposed opposite the first dielectric film such that the second base layer is partially concentric with the first conductor set and wherein a portion of the second protrusions is disposed between the first conductor set and the second base layer in a region where the second base layer is concentric with the first conductor set; and a pinched portion forming an insulating envelope around the first conductor set, wherein the first and second protrusions interpenetrate one another in the pinched portion.
