A passive chipless radio‐frequency identification (RFID) tag based on a log‐periodic (LP) dipole array is proposed, where the tailorable band‐rejection property of the LP aperture is utilised to realise a large number of codes. The proposed tag principle is successfully validated by measurements, where the absence and presence of the band‐rejection is shown to carry the bit information. Its fabrication simplicity is also demonstrated by its implementation on a flexible substrate. Finally, two different tag formation schemes, based on a specific set of resonance suppressions, are discussed in detail.
