A New Approach and Analysis of Modeling the Human Body in RFID-Enabled Body-Centric Wireless Systems

Abstract EN

Body-centric wireless systems demand wearable sensor and tag antennas that have robust impedance matching and provide enough gain for a reliable wireless communication link.

In this paper, we discuss a novel and practical technique for the modeling of the human body in UHF RFID body-centric wireless systems.

What makes this technique different is that we base the human model on measured far-field response from a reference tag attached to the human body.

Hereby, the human body model accounts for the encountered human body effects on the tag performance.

The on-body measurements are fast, which allows establishing a catalog of human body models for different tag locations and human subjects.

Such catalog would provide a ready simulation model for a wide range of wireless body-centric applications in order to initiate a functional design.

Our results demonstrate that the suggested modeling technique can be used in the design and optimization of wearable antennas for different real-case body-centric scenarios.
