MANUFACTURING TECHNOLOGY OF MULTI- BAND CERAMIC TAG ANTENNA FOR RFID

摘要

PURPOSE: A method for manufacturing a ceramic tag antenna of a multiband RFID system is provided to receive a plurality of frequency signals by integrating an RFID frequency band antenna and an ISM(Industrial Scientific Medical) band antenna. CONSTITUTION: A ceramic tag antenna receives two different frequency signals at the same time. The ceramic tag antenna includes a first frequency antenna and a second frequency antenna. A first frequency antenna receives the signal with 900MHz band. The first frequency antenna has a first dielectric substrate. A second frequency antenna receives the signal with 2.6GHz band. The second frequency antenna has a second dielectric substrate. The first and second dielectric substrates have different dielectric constants.
