Abstract (en)
The present disclosure provides a wide-angle radiating leaky cable, from inner side to outer side, including an inner conductive body, an insulating layer, an outer conductive body, and an outer protective casing. A plurality of sections of slots are defined on wall of the outer conductive body, the sections of slots are equally spaced apart from each other. Each section of slots is composed of a plurality of slot modules. Each slot module includes a plurality of slot units independent from each other. The wide-angle radiating leaky cable of the present disclosure obtains wide-angle radiating through a distributed leakage mode. By including a plurality of independent slot units in each slot module, the problems of a small slot, a weak intensity of low-frequency radiation, and a narrow radial radiation angle at high frequency resulted from a high-frequency signal coverage, can be overcome. The slot unit of a specific design can reduce high-frequency attenuation, so that the leaky cable can be compatible with low-frequency coupling and high-frequency attenuation, has a good signal combining ability, and greatly reduce the cost of indoor signal coverage.
