Abstract :
RFID system is a growing technology for various applications such as logistics management and automatic object identification, and medicine management. In recent years, it is suggested to combine with in-body wireless communications to reduce medical error and improve quality of live (QOL) of patient. In this paper, we designed the tag antenna which integrates with an integrated circuit (IC) chip of 9.3 - j55.2 Ω. The antenna is embedded into the three-layered human arm phantom and the performance is simulated by finite-difference time-domain (FDTD) method. In addition, by use of the handy reader, the maximum read range of 1.3 cm of the proposed antenna can be reached, that is approaching the theoretical value of 1.7 cm by the link budget.
