Abstract
A Radio Frequency Identification Device (RFID) tag capable of withstanding electrical stress from induction sealing arrangement and provide shielding against the metallic seal required for induction sealing includes an antenna coil partitioned into a main coil and an auxiliary coil. Both the coils are collocated on two separate overlapping or non-overlapping regions of a dielectric substrate without any galvanic connection therebetween. The main coil is operatively connected with semiconductor chip on the dielectric substrate for necessary RFID activities, while the auxiliary coil operates as a resonator tuned to a certain resonating frequency that enables the auxiliary coil to act as a virtual open circuit to induction sealing frequency and help the semiconductor chip to withstand the electrical stress from induction sealing. The auxiliary coil carries a current during interrogation of the tag by an RFID Reader which provides shielding against eddy currents on the metal seal for induction sealing.
