▎ 摘  要

NOVELTY - The utility model claims a graphene flexible film capable of reducing SAR value, comprising a flexible film main body, the flexible film main body is uniformly provided with a plurality of cross star-shaped holes, one side surface of the flexible film main body is provided with an anti-oxidation protective layer, and the other side surface of the flexible film main body is provided with a gum layer. The graphene flexible film capable of reducing SAR value of the utility model, when the electromagnetic wave is incident into the first cross star hole and the twenty-shaped star hole, the electromagnetic wave will slowly reflect in the hole group, continuously attenuate, which can effectively reduce the SAR peak value, at the same time, by adjusting the distance between the first cross star hole and the twenty-shaped star hole, it can realize the SAR value absorption of different frequency bands, avoid improving the radiation index of the antenna and the SAR peak value; it can be widely used for the 5 G terminal product.
