Evaluation of antenna design and energy harvesting system of passive tag in UHF RFID applications
Backscattering communication-based Radio Frequency Identification (RFID) has been essential to the rapid advancement of IoT devices. However, most RFID applications only utilize relatively simple antenna designs. This work contributes in two ways: we investigate the impact of different antenna configurations on a passive network using backscattering technology. In addition, we evaluate the designs of power harvesting technologies valid for Ultra-High-Frequency (UHF) RFID applications. Our evaluations demonstrate that tailored antenna designs can more efficiently achieve application requirements when compared to a simple universal antenna. In addition, we give recommendations on energy harvesters for applications operating in different scenarios.
