A 5G high-gain array antenna

By using a linear motor to drive the absorbing pin array in a 5G high-gain array antenna to change the dielectric constant, combined with a positioning and shielding mechanism to protect the protective cover, the problem of signal quality degradation caused by the resonant cavity is solved, achieving both no reduction in signal coverage radius and the protective effect of the protective cover.

AI Technical Summary

Technical Problem

A protective cover in an enclosed space can easily form a resonant cavity, which reduces the effective radiated power, shrinks the coverage radius, and consequently reduces the signal transmission quality.

Method used

A 5G high-gain array antenna is designed. A linear motor drives a retractable absorbing pin array to change the equivalent dielectric constant inside the protective cover, thereby disrupting the resonance condition. The protective cover is protected by a positioning mechanism and a shielding mechanism to avoid collisions and icing, thus improving the fixation effect.

Benefits of technology

It effectively disrupts the resonant cavity effect, improves signal transmission quality, prevents damage to the protective cover, extends service life, and ensures that the signal coverage radius is not reduced.

Abstract

The application relates to the technical field of array antennas, in particular to a 5G high-gain array antenna, one end of each fixed plate is fixedly connected with a protective cover, each protective cover is fixedly connected with an antenna body, the inner wall of each protective cover is fixedly connected with a linear motor, the output end of each linear motor is fixedly connected with a telescopic wave-absorbing peg array piece through a connecting shaft, each telescopic wave-absorbing peg array piece is located on the outer side of the corresponding antenna body, and a plurality of heat dissipation scales are connected on each protective cover along the axial line direction at equal intervals. After the linear motor is started, the telescopic wave-absorbing peg array piece is driven to move through the connecting shaft, the equivalent dielectric constant in the protective cover is changed after the telescopic wave-absorbing peg array piece moves, the resonance condition is destroyed, the standing wave distribution is disturbed, the resonance cavity effect cannot be formed in the protective cover, the effective radiation power cannot be reduced, the covering radius cannot be reduced, and the signal transmission quality is improved.
