NOVELTY - The utility model claims a graphene RFID electronic tag based on PET base material, comprising: an antenna, an electronic chip, and a substrate; the antenna comprises a first antenna arm, a short circuit ring and a second antenna arm connected with each other, 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 are arranged in a threaded structure; 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 double-thread structure of the utility model can increase the antenna arm in the given space, so as to reduce the length-width ratio of the antenna arm, the input impedance curve of the antenna is more smooth, the matching bandwidth of the chip is increased, the performance of the tag is more stable, and the antenna volume of the application is small, which is good for miniaturization of the antenna.
