Abstract (en)
[origin: EP0360415A1] A high frequency transmission circuit (1) is provided comprising a continuously porous, planar dielectric sheet (2) having an electromagnetic wave propagating circuit (3,4) therein formed by a dielectric material of a higher permittivity impregnated into portions of the dielectric sheet (2) in the thickness direction thereof. The planar dielectric sheet (2) is preferably of porous expanded polytetrafluoroethylene, and the dielectric material used to form the electromagnetic wave propagating circuit may be tetrafluoroethylene-hexafluoropropylene copolymer, a tetrafluoroethylene-perfluoroalkylvinyl ether copolymer, a tetrafluoroethylene-ethylene copolymer or a tetrafluoroethylene dispersion.
