Abstract
The composite heat dissipation structure includes a grid tape, a buffer layer and a ferrite layer that are stacked in sequence, and a flexible printed circuit board arranged at one side of the ferrite layer facing the grid tape. The flexible printed circuit board includes a substrate and a conductive layer on at least one side of the substrate. The conductive layer has a heat dissipation pattern and a communication antenna pattern, and an orthographic projection of the heat dissipation pattern on the substrate and an orthographic projection of the communication antenna pattern on the substrate do not overlap each other.
