▎ 摘  要

NOVELTY - The utility model claims a graphene RFID electronic tag based on copper plate paper base material, comprising: an antenna, an electronic chip and a substrate, the antenna comprises a first antenna arm connected with each other, a short circuit ring and a second antenna arm, the first antenna arm and the second antenna arm respectively symmetrically arranged along two sides of the short circuit ring, the first antenna arm and the second antenna arm respectively a connecting part and a bending part, the connecting part is connected respectively the bending part and the short circuit ring, the connecting part further has a corner, so as to make the first antenna arm, the included angle between the second antenna arm and the short circuit ring is adjustable; the electronic chip is connected to the short circuit ring, so that the induction current activates the electronic chip internal circuit and forms a sensing magnetic field; the substrate is used for bearing the antenna and the electronic chip; The utility model makes the antenna input impedance tend to smooth, the matching bandwidth of the antenna and the electronic chip is increased, the electronic tag performance is more stable, the working efficiency is high, and the antenna size is small, the structure is simple, the cost is low, and it is easy to be combined with other objects.
