RFID TAG ANTENNA MODULE USING A DIMENSION OF AN RFID TAG ANTENNA, AND AN RFID TAG USING THE SAME

摘要

PURPOSE: An RFID tag antenna module and an RFID tag using the same are provided to control impedance and an operation frequency by controlling a length of an impedance control part of an RFID tag antenna.;CONSTITUTION: An RFID tag antenna module(420) includes a substrate(320), an RFID tag chip(330), and an RFID tag antenna. The RFID tag chip is arranged on the substrate. The RFID tag antenna is connected to the RFID tag chip, and includes a first pattern(360), a second pattern(370), a first impedance control part(380), and a second impedance control part(390). The first pattern and the second pattern have a loop shape. The first impedance control part is positioned in an inner space of the first pattern. The second impedance control part is positioned in an inner space of the second pattern. The first impedance control part and the second impedance control part controls impedance and an operation frequency by controlling a dimension of the first pattern and the second pattern.;COPYRIGHT KIPO 2010
