Controlled impedance cable
First Claim
1. A woven electrical transmission cable for transmitting high-frequency signals having a controlled impedance comprising:
- a plurality of longitudinal conductor wires arranged in a substantially side-by-side relationship for transmitting said signals;
a pair of longitudinal ground wires carried between next adjacent conductor wires longitudinally coextending in a substantially parallel relationship with said conductor wires providing an independently associated ground wire on each said of each respective conductor wire to isolate each said conductor wire;
said conductor wires and ground wires interwoven with insulating fiber strands defining a woven pattern;
said woven pattern including said insulating fiber strands woven in the warp and filling directions;
said conductor wires being woven in said woven pattern so as to have an undulating shape; and
said associated ground wires being spaced from each respective conductor wire in said woven pattern so as to isolate and fix the impedance of each said conductor wire at a desired impedance value;
whereby the impedance of each conductor wire may be matched regardless of conductor wire symmetry for producing transmission of uniform signals with reduced cross-talk interference.

Abstract
A woven electrical cable comprising a plurality of longitudinal conductor wires arranged in a substantially side-by-side manner for transmitting signals with a pair of longitudinal ground wires carried between adjacent conductor wires longitudinally coextending in a substantially parallel relationship with said conductor wires providing an associated ground wire on each side thereof for isolating a respective conductor wire. The conductor wires and ground wires are interwoven with insulating fiber strands to define a woven pattern with the associated ground wires being spaced from each respective conductor wire in the woven pattern so as to isolate and set the impedance of each conductor wire at a desired impedance value whereby the cable impedance may be controlled producing transmission of uniform signals with reduced cross-talk interference.

6. A woven electrical transmission cable for transmitting high-frequency signals having controlled impedance and reduced cross-talk interference comprising:
-
a plurality of longitudinal conductors arranged in a substantially side-by-side configuration for transmitting said signals; an exclusive ground wire laterally spaced next adjacent each side of each said conductor defining an exclusive ground pair for isolating each said conductor; said conductors and ground wires being interwoven with fiber warp and filling strands defining a woven pattern therewith, said conductors being woven in an undulating manner in said woven pattern; said lateral spacing between each said exclusive ground wire and a respective conductor being predetermined in said woven pattern so as to fix the impedance of said conductor at a desired value; and said conductor wires being effectively isolated by said pair of exclusive ground wires so as to permit alteration and variation in the spacing between conductor wires to reduce cross-talk interference without changing said desired impedance value; whereby the impedance of each conductor may be matched producing a transmission cable having a controlled impedance and reduced cross-talk interference for transmitting uniform signals. - View Dependent Claims (7, 8, 9)
