Title:
RF TAG FOR EMBEDDING IN TIRE, AND RF-TAGGED TIRE
Document Type and Number:
WIPO Patent Application WO/2020/075732
Kind Code:
A1
Abstract:
[Problem] To provide: an RF tag that can ensure communication performance when embedded in wide tires, including vulcanized tires; and an RF-tagged tire that incorporates such an RF tag. [Solution] This RF tag 10: is a dipole-antenna RF tag 10 that is to be embedded in a tire; and comprises an IC chip 3, a first antenna wire 1 and a second antenna wire 2 that are respectively connected to two terminals of the IC chip 3, and a chip inductor 4 that is connected between the two terminals of the IC chip 3. The chip inductor 4 and the internal equivalent capacity 5 of the IC chip 3 form a rectification circuit. The rectification circuit rectifies the impedance between the IC chip and the antenna lines at a communication frequency for the RF tag 10. This RF-tagged tire 100 has an RF tag 10 that incorporates a rectification circuit embedded therein, which makes it possible for a reading device to reliably read information that is unique to the tire.
