Abstract

The rigorous electromagnetic characterization of passive UHF radio-frequency identification (RFID) tags is a challenging task which has been much discussed in literature over the years. The solutions to faced it up are both commercial and lab-made, but both use the same analytical model to describe the environment where to perform the measurement. In this work, some considerations about how a new metric called Saw-Tooth profile, introduced in a previous work, could be used in order to estimate how well the mathematical model matches the real measurement scenario, is proposed, in order to allow for rapid and rigorous performance evaluation of UHF RFID tags even in nonanechoic environments. The appropriateness of the proposed approach is demonstrated by comparing theoretical data with measurement performed in both anechoic chamber and in different non-anechoic environments.
