Abstract
Described are RFID structures and methods for forming RFID structures. An RFID structure includes a loop antenna assembly, an antenna substrate supporting the loop antenna assembly, and a shielding layer parallel with a plane defined by the antenna substrate. The loop antenna assembly has a stand-alone resonant frequency of f1 above or below a standardized reader frequency range. The loop antenna includes an antenna track and at least two contact pads. The loop antenna assembly in combination with the shielding layer has a resonant frequency of f2 below the standardized reader frequency range. If positioned against a metallic surface, the loop antenna assembly in combination with the shielding layer has a resonant frequency within the standardized reader frequency range.
