Abstract
The present invention is a flexible low loss coaxial cable comprising a cylindrical plastic rod, an inner conductor surrounding the plastic rod, a dielectric layer surrounding the inner conductor, and a tubular metallic sheath closely surrounding the dielectric layer. The coaxial cable can further include a protective polymer jacket surrounding the sheath. The cylindrical plastic rod supports the inner conductor in bending and can be formed around a central structural member. The present invention also includes a method of making flexible coaxial cable.
Claims18
A coaxial cable comprising:
- a cylindrical plastic rod;
- an electrically conductive tubular inner conductor surrounding said plastic rod, provided by forming a metal strip into a tubular configuration with the longitudinal side edges of the strip butted together and joined by a continuous longitudinal weld, and adhesively bonded to the plastic rod;
- a continuous foam polymer dielectric layer closely surrounding the inner conductor;
- and
- a tubular metallic outer sheath closely surrounding the foam polymer dielectric layer.
