Abstract (en)

A transmission line (1) having an electromagnetic wave energy transmitting core (2) formed of unsintered or partially sintered polytetrafluoroethylene, the core (2) being rectangular in cross-section, and the line having an electrically conductive layer (4) disposed outside the core, preferably on the outside surface of at least a portion thereof. The electrically conductive layer is preferably formed by polytetrafluoroethylene tape containing carbon fibres.
