Abstract: A stripline cable is provided comprising a dielectric layer and a plurality of sets of narrow signal conductors and wider ground conductors which are disposed in confronting relation to each other with the dielectric layer sandwiched therebetween. The signal and ground conductors are alternately arranged transversely of the conductors. The dielectric layer is preferably made of porous polytetrafluoroethylene resin. With this arrangement, crosstalk in the stripline can be greatly reduced and signals can be transmitted at higher speeds over the stripline.
