  • Patent number: 10311355
    Abstract: This disclosure describes RFID tags that include capacitive shields to capacitively couple with antennas of the RFID tags when exposed to threshold levels of electromagnetic energy, such as when placed in a microwave. In some instances, these capacitive shields comprise a material that is both thermally conductive and electrically conductive. When exposed to electromagnetic energy of a high frequency, the capacitive shield may capacitively couple to the antenna of the RFID and, thus, may receive energy from the antenna. Given the properties of the capacitive shield, the capacitive shield may convert this energy into thermal energy and dissipate this heat into an ambient environment of the RFID tag. By doing so, the capacitive shield lessens the risk that dangerous arcing will occur from the electromagnetic energy.
