Abstract

See full text

A three-dimensional graphene antenna includes a three-dimensional graphene radiation layer, a dielectric substrate, a metal layer and a feeder line. The three-dimensional graphene radiation layer is made from porous three-dimensional graphene. A preparation method of the porous three-dimensional graphene includes steps of preparing pressurized solid particles by pressurizing gas into solid micro particles, mixing the pressurized solid particles with a graphene oxide dispersion liquid, removing liquid nitrogen under high pressure and low temperature such that the graphene oxide flakes enwrap around the pressurized solid particles, obtaining a graphene oxide block containing the pressurized solid particles by extruding, sublimating the pressurized solid particles in the graphene oxide block into gas, forming holes in the graphene oxide block and annealing, thereby obtaining the three-dimensional graphene. The three-dimensional graphene has a porous three-dimensional conductive network structure, which is able to be in any shape without any pollution.
