Abstract

A leaky coaxial cable is characterized in that double-row slotted hole groups are arranged on an outer conductor along the axial direction of the cable, the centers of the double-row slotted hole groups coincide with the central axis of the cable, each row of slotted hole group comprises a plurality of slotted hole arrays which are periodically arranged along the axial direction of the outer conductor, and the pitches P of the slotted hole arrays are the same and are selected according to the use frequency; the gain G generated by the double-row slot group meets the requirement, the coupling loss can be reduced, the radiation direction is controlled by adjusting the slot angle alpha, the energy is concentrated in the receiving direction, the effective field intensity is increased, the waste of invalid energy is reduced, the use distance of the cable is increased, and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of communication cable manufacturing, in particular to a leaky coaxial cable. Background technique [0002] With the advancement of wireless communication technology, the frequency of use continues to increase. The higher the frequency of use, the greater the transmission attenuation of the signal in the leaky coaxial cable as the transmission channel, the shorter the length of the leaky coaxial cable, and the more intermediate equipment. The larger the project volume, the larger the project cost. Compared with 2700MHz and 3700MHz, the attenuation increases by 110-120%. How to reduce the attenuation and increase the radiation intensity, so that the leaky coaxial cable can not only exert its own advantages, but also overcome its own defects to the greatest extent. The research goal within is to adjust the lower attenuation of the slot type, increase the gain of the slot type, enhance the radiation intensity, ...
