Coaxial cable structures and methods for manufacturing the same
First Claim
1. A coaxial cable comprising:
- (a) a signal wire;
(b) at least one substantially straight drain wire spaced apart from and parallel to said signal wire;
said drain wire being in the same plane with said signal wire for the entire length of said cable;
(c) an elongated minor matrix of dielectric material, within which said signal and drain wires are longitudinally embedded, said minor matrix having an outer surface through which each of said drain wires is partially exposed;
substantially more of the surface of each of said drain wires being embedded than being exposed;
(d) a conductive shield overlying said elongate minor matrix, in electrical contact with substantially all of the surface of the part of the exposed portion of each of said drain wires facing said shield; and
,(e) a major matrix of dielectric material overlying said shield.

Abstract
Novel discrete coaxial cable and coaxial cable assembly constructions are disclosed. One preferred embodiment of the invention is a flat coaxial cable assembly. The invention also provides a novel method for manufacturing the coaxial elements which are the primary structural components of the coaxial cables and assemblies. In this method a signal wire and at least one drain wire are embedded in a minor matrix of dielectric material. A portion of the minor matrix material is peeled or skived away to expose the drain wire or wires. The resulting product is then wrapped in metal foil so that the foil makes electrical contact with the exposed drain wires. This step yields a completed coaxial element. A single element may be embedded in a major matrix of dielectric to yield a coaxial cable or several elements may be so embedded to yield a coaxial cable assembly.
