Abstract

This paper reports the first conformal RFID antenna printed on a flexible magnetic composite material for the UHF frequency band. The target applications are wearable RFIDs and bio-monitoring wireless probes. The successful implementation of the flexible magnetic composite material allows the tag miniaturization and provides excellent electrical performance in the 480 MHz band. First, the material is chosen for optimal electric and magnetic losses, then the antenna is designed for both the non-magnetic material and the magnetic one to prove the miniaturization. Finally, the effect of bending the antenna on the measured return loss performance is investigated.
