A high-field emission tolerant RFID tag device that may be secured to a product to be cooked, heated, reheated and/or thawed in a heating apparatus such as, but not limited to, a microwave oven and that does not need to be removed from the product before initiating the heating process. The RFID device is microwave safe and does not damage the product or food item to which it is attached during the microwave process, and may contain data to control the microwave process. The microwave safe RFID tag comprises a split ring (or shield) conductor formed on one side of a substrate (or dielectric), a coil antenna conductor formed on an opposite side of the substrate, and a RFID chip. The split ring conductor capacitively couples to the coil antenna conductor via the dielectric and a gap in the split ring conductor prevents arcing.
