A coaxial cable of the present invention comprises a center conductor, a dielectric surrounding the center conductor, a shielding tape surrounding the dielectric, a braided metal surrounding the shielding tape, and an outer jacket surrounding the braided metal. The shielding tape comprises: (i) a first shielding layer bonded to a first separating layer; (ii) a second shielding layer bonded to the first separating layer and a second separating layer; and (iii) a third shielding layer bonded to the second separating layer. The present invention eliminates the potential problem of the outer shielding structures separating and interfering with connector attachment. Furthermore, the use of three or more shielding layers in the shielding tape of the present invention improves the flex life of the shield tape by covering micro-cracks in the metal layers with additional shielding layers, thus reducing signal egress or ingress. Accordingly, the present invention provides cost savings and/or an improvement in shielding performance.

Methods of design, manufacture and implementations of balanced twisted pair cables with a barrier tape or shield, with tuned attenuation, impedance, and coupling properties. A filler is included within the cable to separate the pairs and provide a support base for the shield, allowing for optimized ground plane uniformity and stability for tuned attenuation, impedance, and coupling properties. The filler orientation, shape, and size provides support for the shield such that a gap is provided between the shield and the twisted pairs with a given minimum size without increasing the maximum cable core size. The length of arms of the filler may be adjusted to fine-tune the size and shape of this gap and control air-dielectric volume and radial contact or spacing between any pair(s) and the shield, tuning electrical performance characteristics caused by non-linear effects of electromagnetic interactions at short ranges between the pairs, shield, filler, or other components.
