A COOKING APPARATUS USING MICROWAVE

摘要

PURPOSE: A microwave cooking apparatus is provided to facilitate impedance matching by employing a small-size antenna and to evenly heat an object in a cavity by selectively outputting microwave according to calculated efficiency. CONSTITUTION: A microwave cooking apparatus comprises a plate(634), a microwave transmission line, a first metal part(620), a second metal part, a third metal part, and a fourth metal part. Microwave is transmitted into a cavity(134) through the microwave transmission line. The first metal part is connected to one end of the transmission line and extended in a specific direction. The second metal part is connected to one end of the first metal part and extended to contact the plate. The third metal part is connected to one end of the transmission line and extended in a specific direction. The fourth metal part is connected to one end of the third metal part and extended to contact the plate.
