the 5g radome is an important part of the 5g base station, which is used to protect the antenna system from the interference of the complex external environment, and improve the accuracy and service life of the antenna.
however, these radomes are persistently exposed to the complex outdoor environment for a long time, such as the continuous impact of raindrops. rain attenuation (during rainfall, 5g signals can be easily disturbed by raindrops or water films on the radomes) of 5g radomes is one of the bottlenecks restricting 5g communication development.
therefore, ideal superhydrophobic coatings used for prevention of rain attenuation on 5g weather radomes should fulfill the advantages of excellent impalement resistance, mechanical robustness, and weather resistance.
the research team from lanzhou institute of chemical physics, cas, found that superhydrophobic coatings are expected to solve rain attenuation of 5g radomes, and fulfill the advantages of excellent impalement resistance, mechanical robustness, and weather resistance.
the design of superhydrophobic coatings, with all these merits mentioned above, therefore feature an isotropic three-tier hierarchical structure, a dense but rough surface at the nanoscale, and chemically inert composition with low surface energy.
in the future, the large-scale preparation, extension, and practical application of the coatings will efficiently prevent rain attenuation of 5g weather radomes.
