Innovating RFID for Future Applications: A Capacitive Coupled Antenna Design for UHF RFID Application
The developed antenna design is not an improvement of the AK5 tag but rather a new approach that changes the application of the tag from a near field to a far field product. The approximate 400% increase in area with this new far field antenna may not allow operation with previously defined near field applications, but it does extend the application spectrum and allows the use of the same RFID chip infrastructure.
