ABSTRACT:
A microwave responsive heating device useful in microwave packaging for capturing microwave energy in a microwave oven and transmitting the energy to a surface of a food item in a concentrated form to grill, crisp, or brown the surface thereof. The heating device includes an antenna for collecting the microwave energy and a transmission device for transferring the collected energy from the antenna to a surface of a food item. Preferably, the heating device forms an integral portion of the interior of a food package to allow a food item to be stored and cooked therein. The antenna and the transmission device are made from electrically conductive materials and are shaped to, not only, capture and transmit microwave energy efficiently, but also to enhance the intensity of the microwave energy in a concentrated form.
