Design of RFID Tag Antenna with High Impedance Surface Structure to Reduce Metallic Effect

In this study, we design and fabricate novel tag antennas, which can be used on the metallic surface for radio frequency identification systems. We first focus on the effects when the antenna is placed on the metallic surface. Based on the simulation results, we investigate how the parameters of the antennas are affected. The helps us find solutions to reduce the effects when the antennas are placed on the metallic surface.
In order to conform to the IC chips of RFID and reduce the influence of metal objects, we use the structure of the dipole antenna is used as the basis of the novel tag antenna design. And we employ the high impedance surface periodic structure which behaves similarly to a perfect magnetic conductor in the design of the novel tag antenna. The novel tag antenna is able to work normally when it was attached on the surface of the carton or metallic object. Finally, the tag antenna is fabricated and measured in a chamber. The measured results agree with simulated ones well.
