Abstract
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 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.
