High speed transmission cable
First Claim
1. A high speed transmission cable comprisinga 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.

Abstract
The present invention relates to a high speed transmission cable (100A) that includes a first conductor set (110), a dielectric film (120A) at least partially concentrically disposed around the first conductor set (110) and a pinched portion (150A) forming an insulating envelope (140A) around the first conductor set (110). The dielectric film (120A) includes a base layer (122) having a plurality of first protrusions (124) formed on a first major surface of the base layer (122), wherein the dielectric film (120A) is disposed such that the base layer (122) is partially concentric with the conductor set (110) and wherein a portion of the first protrusions (124) is disposed between the first conductor set (110) and the base layer (122) in a region where the base layer (122) is concentric with the first conductor set (110).
