NEAR FIELD COMMUNICATION (NFC) COMPACT ANTENNA CAPABLE OF ENHANCING ANTENNA FREQUENCY CHARACTERISTICS AND AN RFID TAG USING THE SAME

摘要

PURPOSE: An NFC compact antenna and an RFID tag using the same are provided to maximize the sensitivity of recognition by maximizing a resonant frequency through the interference between a ceramic body and an antenna pattern.;CONSTITUTION: A dielectric substrate (110) is made of a dielectric ceramic or an FPCB. The dielectric substrate has a through hole (113) which penetrates the center of the substrate. The through hole is charged with a ferrite. Loop antennas (120a, 120b, 120c, 120d) are formed on the dielectric substrate. A ferrite substrate (130) is attached to the dielectric substrate and part of the ferrite substrate protrudes outside the dielectric substrate.;COPYRIGHT KIPO 2013
