Abstract
A microwave oven heats all food in an appropriate manner even if food items are simultaneously placed at multiple locations in a heating chamber. An auxiliary antenna is periodically stopped at an orientation corresponding to a position where a lowest temperature was detected at the start of the heating operation. Between stopped periods, the auxiliary antenna is rotated for a period to apply heat evenly to all food in the oven. If multiple low-temperature points are detected, the central position of these multiple low-temperature points is used for applying concentrated heat.
