TWO DIMENSION PLANE STRUCTURE METHOD RFID TAG FOR TIRE

摘要

A 2D(Dimensional) planar RFID(Radio Frequency IDentification) tag for a tire is provided to protect an RFID tire tag from pressure and temperature change applied to the tire, and prevent void or flaw generated by stress continuously applied to the tire by making the RFID tire tag in a thin film type with a silver complex compound and a polyimide film. An antenna(40,50) is formed by printing ink composition including a silver complex compound on a polyimide film and is oscillated by an electric wave received from an RFID reader. A circuit unit(60) is operated by receiving power from the electric wave. The circuit unit includes at least one closed loop(41,42) generating induced reactance on a plane of the polyimide film. Capacity reactance of the circuit unit is offset through the induced reactance formed by the closed loop.
