Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment and accompanying drawing, to this
Invention is described in further detail.
With reference to shown in Fig. 1 to Fig. 4, near-field communication equipment provided in an embodiment of the present invention, including apparatus body 1, lid are located at
The positive plastic cover plate 2 of apparatus body 1 and lid are located at the plastic back plate 3 of the reverse side of apparatus body 1, the inner side of plastic cover plate 2 and modeling
Respectively post a flexible near-field communication aerial 4 in the inner side of material backboard 3.The cover plate 2 and backboard 3 of plastic material will not cause to hide to signal
Gear, ensure good signal transmitting and receiving performance.
Flexible near-field communication aerial 4 includes the first Kapton substrate 41, the and of the second Kapton substrate 43
The graphene antenna stack 42 being located between the first Kapton substrate 41 and the second Kapton substrate 43.Polyamides is sub-
Amine has excellent high temperature resistant, radiation hardness, resistant to chemical etching and electrical insulation capability, and ultra-thin Kapton can be achieved excellent
Good electrical insulation capability, it is lightening to be advantageously implemented equipment.Graphene is a kind of accurate two-dimentional material of an only atomic layer level thickness
Material, there is good intensity, flexible, conductive, heat conduction, optical characteristics, making antenna stack using graphene can be by the thickness of antenna stack
