Title:
FIELD IMPROVING SYSTEM PROVIDED WITH RESONATOR
Document Type and Number:
WIPO Patent Application WO/2008/062828
Kind Code:
A1
Abstract:
Provided is a field improving system having a resonator for improving environment for communication among a sensor, a tag and a noncontact IC card. The system is used for RFID (Radio Frequency Identification) sensor, IC tag and noncontact IC card. Resonators (8) are added to a sensor (Sensor), a tag (T) and a noncontact IC card (C). The resonator (8) is composed of a coil (5) and a capacitor (7). A magnetic body (6) is attached to the coil (5) of the resonator (8), and the strength of the magnetic field is increased.
