Log-Periodic Dipole Array Antenna as a Chipless Radio-Frequeny Identification (RFID) Tag

摘要

A passive chipless Radio-frequency identification (RFID) tag based onlog-periodic (LP) dipole array is proposed, where the tailorable band-rejectionproperty of the LP aperture is utilized to realize large number of codes. Theproposed tag principle is successfully validated using measurements, where theabsence and presence of the band-rejection, is shown to carry the bitinformation. Its fabrication simplicity is also demonstrated by itsimplementation on a flexible substrate. Finally, two different tag formationschemes, based on specific set of resonance suppressions, are discussed indetailed.
