RFID TAG EQUIPPED WITH AN ANTENNA MADE OF TRANSPARENT MATERIAL

摘要

PURPOSE: An RFID tag including an antenna of transparent material is provided to prevent the intentional removal of an RFID tag by not recognizing the attachment of non-attachment material. CONSTITUTION: A main antenna(13) is connected to a chip(11) for RF data communication with an RFID(Radio Frequency ID) reader. An insulating layer(20) insulates the main antenna and a sub antenna and forms capacitive connection of two antennas. A dielectric layer(40) is attached to the lower part of the sub antenna and prevents the exposure of the surface of the sub antenna. The main antenna is manufactured in transparent or semiconductor-transparent electrode material.
