Abstract
In a microwave heating apparatus of the invention, microwaves from oscillation partsare divided into a plurality of microwaves by power division partsand inputted to amplification parts, and desired microwave powers from the amplification parts are supplied from feeding partsto a heating chamber. Reflected powers reflected from the heating chamber to the amplification parts via the feeding parts are detected by power detection parts. Each of the feeding parts has a plurality of antennas for supplying the microwaves having different characteristics to the heating chamber, and a control partextracts an oscillating frequency with which the reflected powers detected by the power detection parts are minimum, and causes the oscillation parts to oscillate at the extracted oscillating frequency so as to supply the microwaves having the different characteristics from the plurality of antennas to the heating chamber.
