Claim:
1. An electrical ribbon cable, comprising: a plurality of conductor sets, each conductor set comprising at least two elongated insulated conductors extending from end-to-end of the cable, each conductor set substantially surrounded by and fixably coupled to a shielding film such that a consistent spacing is maintained between the insulated conductors of each conductor set along the length of the cable; and first and second dielectric films extending from the end-to-end of the cable and disposed on opposite sides of the cable, such that in transverse cross-section, the first and second dielectric films form cover portions of the dielectric films substantially surrounding each conductor set and pinched regions of the dielectric films on each side of each conductor set, the cable comprising a transition portion on each side of each conductor set defined by the first and second dielectric films and the conductor set, the transition portions providing gradual transitions between the cover portions and the pinched regions of the first and second dielectric films, such that when the cable is in an unfolded planar configuration: at least one of the first and second dielectric films has a radius of curvature across an entire width of the cable that is at least about 50 micrometers; and a ratio of a minimum radius of curvature of the first dielectric film in the cover portions of the first dielectric film to a minimum radius of curvature of the first dielectric film in the transition portions of the first dielectric film is in a range from 2 to 15.
