For the reduction of 5G base station volume, the integration requirements of antenna and wave device also increase, which also hinders the size of the small base station radiator.However, if the heating parts of 5G base station are small, powerful and the heat accumulated by long-time operation is not distributed in time, it will seriously affect the communication signal and service life of 5G small base station.
Communication base stations are a strategic infrastructure to realize information technology. With the layout of the 5G industry, more base stations will be deployed for 5G ultra-dense networks.During the operation, the base station equipment will radiate electromagnetic waves, interfere with the operation of other equipment and endanger public health; on the other hand, other electromagnetic waves.Wave-absorbing material is an effective means to solve electromagnetic interference, which is particularly urgent in the commercialization of 5G mobile communication today.
In addition to the overall shielding of the base station shell, the electromagnetic elements need to be screened locally internally to prevent mutual interference of signals.In base stations, especially in the case of large antenna matrix, the traditional shielding mode is difficult to meet the demand of millimeter wave.For electromagnetic shielding is not only a barrier, but also can use the means of absorption.Electromagnetic shielding materials in the field of 5G require broadband, millimeter wave range application, and the shielding efficiency of medium and low frequency and high frequency electromagnetic waves.Wave absorption material can be used to increase the anti-interference, but also very suitable for the local electromagnetic protection of base station equipment, to achieve a good clean electromagnetic environment.
