Abstract
The invention provides a bending-resistant broadband radiant leakage coaxial cable. The cable comprises an inner conductor extending axially, and an insulator, an outer conductor and an outer sheath arranged outside the inner conductor in sequence from inside to outside. The inner conductor is a spiral corrugated copper tube. The outer conductor closely coats the insulator, and is periodically provided with slots along the axial direction. Roller lines with V-shaped cross sections are arranged on the outer surface of the outer conductor. As a spiral corrugated copper tube is adopted as the inner conductor and the V-shaped roller lines are machined on the outer surface of the outer conductor through a roller device, the cable has good bending resistance performance. In addition, the leakage coaxial cable is applicable to a wider band, and the copper strip used as the outer conductor is continuous, uniform and defect-free, so that controlled electromagnetic energy can be evenly radiated out and received along the line to cover the blind area of the electromagnetic field, and thus, smooth mobile communication is achieved.
