Abstract

In this work, a flexible narrowband fully passive printable multi-resonator is proposed for UHF RFID chipless tags working within the UHF band. The multi-resonator structure is flexible, has a compact size, a low cost of fabrication, and a very compact frequency bandwidth for each of the resonators, which unambiguously correspond to one stored data bit. The data can be encoded using spectral signatures, providing a unique ID for every tagged object. The multi-resonator has been designed using a general-purpose 3D CAD, CST Microwave Studio.
