Abstract: Provided is a frequency domain-based printable chipless radio frequency identification (RFID) tag of a quadrilateral open resonator, and belongs to the field of radio frequency identification. The frequency domain-based printable chipless RFID tag of a quadrilateral open resonator includes a rectangular dielectric substrate having a metal grounding layer disposed at a bottom thereof. Four groups of quadrilateral open resonance units and two parallel symmetrical antennae are disposed above the rectangular dielectric substrate, and each group of quadrilateral open resonance units are symmetrically disposed on two sides of the two parallel symmetrical antennae. The present disclosure utilizes the quadrilateral open resonator to encode data, and capacitance and inductance of the resonance unit can be adjusted, so that the tag has the advantages of convenient encoding, high encoding density, and miniaturization.
