Iron tower wave-absorbing net structure for installing 5G antenna and geometric dimension determination method

Abstract

The invention relates to an iron tower wave-absorbing net structure used for installing a 5G antenna and a geometric dimension determination method, and belongs to the technical field of communication base stations, the wave-absorbing net structure is arranged on an iron tower on the rear side of the antenna, the wave-absorbing net structure comprises multiple layers of metal nets which are sequentially arranged in a staggered mode from top to bottom, the metal nets are of a square structure, and net holes of the metal nets are square; loss absorption of electromagnetic waves radiated by the antenna is achieved through eddy current, and scattering of the electromagnetic waves by the iron tower is reduced.

Description

technical field [0001] The invention relates to the technical field of communication base stations, in particular to a structure and a method for determining a geometric dimension of an iron tower wave-absorbing network for installing a 5G antenna. Background technique [0002] With the continuous improvement of mobile communication network capacity and coverage requirements, the number of communication base stations is also increasing. Therefore, the "shared iron tower" that adds the function of communication base station to the existing high-voltage transmission line iron tower is becoming a new resource sharing mode. [0003] The open sharing of "power towers" and "communication towers" constitutes a huge "good news" for promoting the coordinated development of power and communication infrastructure, especially for the upcoming 5G network deployment. The power poles and towers along the line are used for communication construction, which can promote the wide coverage and...

Problems solved by technology

[0005] However, due to long-term outdoor suspension, external forces such as wind, rain and snow will inevitably change the inclination angle

After this happens, the electromagnetic wave radiated by the antenna will scatter with the metal body of the iron tower, and the refraction and reflection of the electromagnetic wave by the metal structure of the iron tower will affect the radiation field of the antenna, resulting in the increase of irregular side lobes in the antenna diagram and affecting the communication quality

The current solution to this is to expand the variation range of the downtilt angle of the antenna, but this will increase the volume of the antenna, especially for mature products, it is difficult to change
