Polarization independent chipless RFID tag

Abstract

ABSTRACT Fully printable polarization independent frequency domain chipless radiofrequency identification tag using the harmonic separation capability of Stepped Impedance Resonator is proposed. The data are encoded either using the magnitude or group delay of the backscattered signal. The data encoding capacity of the tag is enhanced using Frequency Shift Coding technique. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1889–1894, 2015
