Title:
WIDE-ANGLE RADIATION LEAKY COAXIAL CABLE
Document Type and Number:
WIPO Patent Application WO/2020/103150
Kind Code:
A1
Abstract:
Disclosed is a wide-angle radiation leaky coaxial cable, wherein same is successively provided with an inner conductor (1), an insulating layer (2), an outer conductor (3) and an outer sheath (4) from the inside out. Several slot base blocks composed of multiple slot modules (7) are provided in a wall of the outer conductor (3) at equal intervals, and each slot module (7) comprises multiple independent slot units (8). The wide-angle radiation leaky coaxial cable realizes wide-angle radiation by means of distributed leakage. Each slot module (7) is provided with multiple independent slot units (8), thereby solving the defects of the reduced intensity of low-frequency radiation and the narrowing of a high-frequency radial coverage angle due to the shortening of a radiation slot, in order to achieve high-frequency signal coverage. The specifically designed slot units (8) are used for reducing high-frequency attenuation so that the leaky cable is compatible with low-frequency coupling and high-frequency attenuation, and has a good signal combining capacity, thereby greatly reducing the cost of indoor coverage.
