Detuned dipole array backed by rectangular plate applied as chipless RFID tag

A chipless RFID tag designed as detuned dipole array backed by rectangular plate is proposed. Its main feature is frequency notched RCS response which provides high read range of the tag. Information encoding ability was investigated on three example bit words. It has been found that proposed structure exhibits narrow resonances with higher bit density than other presented structures and thus seems to be a good candidate for compact high density chipless RFID tags. Performance parameters of the structure has been evaluated by EM simulator Zeland IE3D and verified by monostatic measurement in an anechoic chamber.
