Radio frequency identification tag and manufacturing method thereof

A radio frequency identification tag comprising:

• a substrate;
• an antenna unit provided on the substrate and configured to transmit and receive signals;
• an integrated circuit unit spaced apart from the antenna unit on the substrate;
• and
• an interrupter and a delay circuit unit connected in parallel between the antenna unit and the integrated circuit unit,
• wherein the interrupter comprises a variable portion and a fixed portion opposite the variable portion,
• wherein the delay circuit unit comprises at least two electrodes and an active layer between the at least two electrodes.

A method of manufacturing a radio frequency identification tag, the method comprising:

• forming an insulating layer on a substrate;
• printing an antenna unit, an integrated circuit unit, an interrupter and a delay circuit unit on the insulating layer;
• and
• printing the wiring connecting the antenna unit, the integrated circuit unit, the interrupter and the delay circuit unit to each other,
• wherein the delay circuit unit comprises a capacitor and a resistor,
• wherein the interrupter and the delay circuit unit are connected in parallel between the antenna unit and the integrated circuit unit.
