Abstract
A dielectric waveguide in cable form fabricated from polytetrafluoroethylene. An embodiment of cable is a composite of partially sintered PTFE and sintered and unsintered expanded PTFE arranged in such a fashion that the specific gravity of cable decreases from the core to the outer surface.
Claims21
A method for the transmission of electromagnetic waves comprising transmitting said waves using a dielectric waveguide wherein said waveguide comprises a shaped article of porous PTFE having a specific gravity between about 1.45 and about 1.9.
A dielectric waveguide for the transmission of electromagnetic waves comprising an elongated shaped article having one or more layers of expanded, porous polytetrafluoroethylene extending radially outwardly from the center of said waveguide.
A dielectric waveguide for the transmission of electromagnetic waves comprising a shaped article having:
- (a) a core of polytetrafluoroethylene;
- and (b) one or more layers of expanded, porous polytetrafluoroethylene overwrapped on or around said core.
