A multilayered substrate includes first, second, and third insulating layers, and a transmission line. The first insulating layer includes first and second surfaces opposite to each other. A signal conductor of the transmission line is on the first surface of the first insulating layer. The second insulating layer is in contact with the first surface of the first insulating layer. The third insulating layer is in contact with the second surface of the first insulating layer. A dielectric loss of the second insulating layer is lower than a dielectric loss of the third insulating layer. A degree of close contact between the first insulating layer and the third insulating layer is higher than a degree of close contact between the first insulating layer and the second insulating layer.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

A cable is described, including a plurality of substantially parallel conductors extending along a length of the cable and generally lying in a plane of the conductors, and a dielectric film comprising a plurality of pairs of structures, and folded upon itself along a longitudinal fold line so that the structures in each pair of structures face, and are aligned with, each other, each conductor of the plurality of conductors disposed between the structures in a corresponding pair of structures.
