LOW-PROFILE ANTENNA-LESS RFID TAGS AND INTEGRATED CIRCUIT WIRELESSTRANSMISSION APPARATUS

摘要

Disclosed embodiments include a low-profile, high-permeability antenna-less radio frequency identification (RFID) tag for use on large metal objects and other types of objects for which traditional RFID technologies will not work or do not work well. High-permeability materials are in contact with a metal surface, such as a metal container or metallic tape, diverting current into the tag integrated circuit (IC). This type of tag is essentially‘antenna-less’as it uses the ground plane or metallic object to excite currents through the IC. Tags using high-permeability materials in this manner are significantly thinner than those developed using other methods.
