Abstract
A miniature coaxial cable having an outside diameter of less than 0.25 inch (6.3 mm). An inner conductor is surrounded by a foamed polymer dielectric and a continuous corrugated metal outer conductor surrounds the foamed dielectric. The cable of the invention has electrical performance superior to that of prior art cables having braided outer conductors and flexibility superior to that of cables having smooth tubular outer conductors.
Claims18
A miniature coaxial cable for carrying high frequency electromagnetic signals comprising:
- an inner metal core;
- a foamed polymer dielectric surrounding the inner conductor;
- and
- a corrugated continuous metal outer conductor surrounding the foamed polymer dielectric of the cable having an outer diameter less than about 0.25 inch.
A miniature coaxial cable for carrying high frequency electromagnetic signals comprising:
- an inner metal core;
