Abstract

The distance‐dependent reflection coefficients are investigated based on a multi‐ray model at microwave frequency bands. Tag range of passive microwave radio‐frequency identification (RFID) systems is then calculated taking into account the tagged object material characteristic. Obtained values are verified through the precise simulations based on a 3‐D physical finite element model. The results shown that the proposed method provides a good agreement than that obtained by existing methods. The analytical method can be used for the empirical tag range value to avoid reader collision while ensuring system reliability. © 2009 Wiley Periodicals, Inc.
