Abstract
A microwave oven includes a housing defining an interior cavity, a magnetron positioned within the housing and outside of the interior cavity and a micro-wave antenna in electrical communication with the magnetron and positioned adjacent a lower surface of the interior cavity. The microwave oven further includes a heating plate that includes a glass-ceramic substrate defining at least a portion of the lower surface of the interior cavity. The heating plate further includes a resistive-heating coating applied on a portion of the glass-ceramic substrate and defining at least one open micro-wave transmissive path from the micro-wave antenna to the interior cavity.
