Abstract

The paper presented a compact dipole tag antenna with a miniaturized artificial magnetic conductor for UHF RFID on-body applications. Two kinds of artificial magnetic con- ductor are designed and studied in order to insulate the influence from the human body. The miniaturized AMC structure is then placed on the button of a folded dipole tag antenna con- nected with a Monaz® 4 microchip. The tag with the AMC is designed and simulated by the simulator HFSS. The design structure is also constructed to verify the simulation results. The study finds that the tag with the AMC can increase antenna gain and reading range. When the tag is put close to a human body, the foldeddipole tag can achieve about 6 m reading distance.
