Abstract

In this paper, a research on radio frequency identification (RFID) tag for body wearable is presented. Performances of tag and antenna are mainly focused on with the tag patched on human body. Results are available from simulation and measurement to reflect the change of wearable tag performance. A human model with specific posture was set to allow the tag attaching on body in simulation. Impedances and gains were obtained to evaluate the change of tag antenna performance with the tag on five different body positions. In actual measurement, read ranges of tag on different positions of body were measured. Ideal read distances of the tag were calculated using Friis free-space formula with the simulation results to compare with the measured ones. The results demonstrate the performance of tag antenna can be affected by bodily tissue absorbing and antenna bending and posture shielding. It is confirmed the antenna is suitable for UHF RFID tags in passive RFID applications.
