RFID TAG DEVICE AND METHOD OF MANUFACTURING

摘要

Folded radio frequency identification tag devices and methods for high-volume, low-cost production are disclosed. The folded construction of the devices and methods of the present invention can reduce the complexity of the RFID tags by providing a one-sided circuit design. The resonant frequency of the circuits formed on the devices may be tuned by severing selected connections to one or more tuning capacitor plates 50, 52 that form a part of the capacitor structure. Severing connections to the tuning capacitor plates changes the capacitance of the circuit which, in turn, changes the resonant frequency of the circuit. After folding the outer end of the planer antenna coil 20 is connected via connection pads 60, 62 to an inner portion of the coil, where 3C chip can be mounted.
