Title:
BENDING-RESISTANT BROADBAND RADIANT-TYPE LEAKY COAXIAL CABLE
Document Type and Number:
WIPO Patent Application WO/2018/121339
Kind Code:
A1
Abstract:
A bending-resistant broadband radiant-type leaky coaxial cable, comprising an inner conductor (1) extending in an axial direction, and an insulator (2), an outer conductor (3) and an outer sheath (4) 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 (5) in the axial direction; knurls (6) having V-shaped cross sections are provided on the outer surface of the outer conductor. In the cable, a spiral corrugated copper tube is used as the inner conductor, and V-shaped knurls are formed on the outer surface of the outer conductor by pressing with a knurling apparatus, so that the cable has good bending resistance. In addition, the leaky coaxial cable is applicable to a wider band, and a copper strip used as the outer conductor is continuous, uniform and defect-free, so that controlled electromagnetic wave energy can be evenly radiated and received along a line to cover a blind area of an electromagnetic field, and therefore, smooth mobile communication is achieved.
