Patent ID: 6969807

Claim:
A planar type flexible cable, comprising: a longitudinally extended insulated section having a top and a bottom surface and a pair of longitudinally extended and transversely spaced side surfaces, and two ends separately defining a first and a second end; at least one pair of differential-mode signal transmission lines, said differential-mode signal transmission lines being in one pair being horizontally closely spaced inside said insulated section in said transverse direction, and extended in said longitudinal direction of said insulated section from the first end to the second end of said insulated section; and a flat layer of shielding structure provided on at least one of said top and bottom surfaces of said insulated section with a predetermined distance left between said shielding structure and said differential-mode signal transmission lines inside said insulated section, said side surfaces of said insulated section being devoid of said flat layer of shielding structure, and said flat layer of shielding structure providing an impedance value needed by said differential-mode signal transmission lines, said flat layer of shielding structure being a flat layer of net-type shielding structure.
