▎ 摘　　要

NOVELTY - The method involves providing a side surface of a circuit board (10) with a circuit coil (11). Another side surface of the circuit board opposite to the circuit coil is provided with a shielding sheet (20). Powder graphene, dispersing agent and deionized water are mixed to obtain graphene slurry (31). The graphene slurry is coated to a surface of the shielding sheet. Curing and forming treatment to the graphene slurry attached to the shielding sheet is carried out to form a graphene radiating layer (30) on a surface of the shielding sheet. USE - Method for manufacturing an antenna structure of an electronic device (all claimed) i.e. smart card. ADVANTAGE - The method enables reducing the part of the thickness size occupied by the existence of the adhesive, so that the antenna structure can be light and thin, and can satisfy the design requirements of the electronic device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an antenna structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating a method for manufacturing an antenna structure of an electronic device. 10Circuit board 11Circuit coil 20Shielding sheet 30Graphene radiating layer 31Graphene slurry 40Stirring kettle 50Spray gun
