Abstract
A high speed electrical transmission line is provided comprising a signal conductor having an open cell, continuously porous, polymeric insulating material surrounding the conductor, the insulating material having a plurality of openings fused therein, the walls of the openings being solid, fused polymer which provide compressive strength for the otherwise highly compressible porous insulating material. The preferred polymer is expanded, porous polytetrafluoroethylene. The openings may be formed by a laser or by other means.
Claims9
An electrical transmission line comprising a signal conductor, a porous polymeric insulating material surrounding said conductor, said insulating material having at least one opening therein having a wall, the polymeric material at and near said wall being solid, fused polymeric material, whereby said opening provides compressive strength for the otherwise highly compressible, porous material.
