Abstract:
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.
