| Abstract: |
| Tire is made up of rubber，carbon-black and steel wire.The change of these materials and structures will affect the the performance of implanted-in tire radio frequency identification tag(RFID) antenna.The performance’s changes of RFID antenna which was caused by tire materials and steel cord were studied through electromagnetic simulation .Results showed that the resonance frequency of RFID tag antenna decreased with the increase of the tire material dielectric constant.At the same time,the return loss of tag antennaincreased with the increase of tire material dielectric constant.The performance of RFID tag antenna will be better when the antenna perpendicular to the steel wire compared with antenna parallel to the steel wire.The simulation results provided important reference value for the design of RFID tag and for tag implanted form. |
