5G communication electromagnetic waves include two frequency bands, FR1 and FR2. FR1 ranges from 450MHz to 6GHz, while FR2 spans 24.25GHz to 52.6GHz, classified as millimeter waves. Due to the rapid attenuation of these waves in the air, it is necessary to employ ultra-dense networking methods for continuous network coverage. In the future, small and micro base stations will be deployed in crowded areas. To protect human health from electromagnetic radiation, it is crucial to implement electromagnetic shielding for base stations. This can be achieved using efficient electromagnetic shielding materials that absorb or reflect electromagnetic waves, thereby reducing radiation exposure to humans.
