Leaky coaxial cable with directional radiation function

Abstract

The invention discloses a leaky coaxial cable with a directional radiation function, and relates to the technical field of communication equipment. The leaky coaxial cable with the directional radiation function comprises an inner conductor, wherein the surface of the inner conductor is provided with an inner protection layer, the inner protection layer is used for directly protecting the inner conductor, the outer side wall of the inner protection layer is provided with a copper outer conductor, the surface of the outer conductor is provided with a hole groove used for magnetic leakage, the inner side wall of the hole groove is provided with a first blocking grid and a second blocking grid which are used for gathering electromagnetic waves, a protection ring is arranged between the first blocking grid and the second blocking grid, the surface of the protection ring is provided with an outer protection layer used for protecting the outer conductor, and the surface of the outer protection layer is provided with a wear-resistant layer. Through the arrangement of the inner protection layer, the outer protection layer, the wear-resistant layer, the first blocking grid and the second blocking grid, the problems that electromagnetic signals are not concentrated enough and are inconvenient to face one direction in a concentrated mode, the signals are dispersed, radiation is difficult to reach some areas, and radiation intensity is low are solved.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a leaky cable with directional radiation function. Background technique [0002] The leaky coaxial cable has the function of signal transmission and also has the function of antenna. Through the control of the opening of the outer conductor, the controlled electromagnetic wave energy can be evenly radiated and received along the line, so as to realize the coverage of the blind area of ​​the electromagnetic field and achieve mobile communication. unimpeded purpose. [0003] The slots on the outer conductor of the traditional leaky cable are periodically arranged. Although electromagnetic waves can be radiated evenly, the electromagnetic signals are not concentrated enough to be concentrated in one direction. The signals are scattered, making it difficult for radiation to reach certain areas, and the radiation intensity is low. The problem. Contents of the invent...
