Résumé

A reading technique for chipless radio frequency identification (RFID) tags is proposed. It is based on the cross-polarization principle, and unlike classical approach, the introduced technique makes it possible to read classical Chipless tag independently to their orientation. To retrieve the tag identification (ID) the property of short-time Fourier transform (STFT), and a polarization diversity approach are exploited. The former is useful to isolate the tag mode contribution from the total backscattered signal, notably the presence of clutter form surrounding objects. The latter helps to correctly excite the tag resonant scatterers and so to maximize the receiving tag mode energy. The approach has been validated with a laboratory equipment test bench solution, and with a low cost solution.
