Abstract

This paper describes improvement on heating efficiency in microwave oven. An asymmetrical rotary stub is proposed as an adjustable matching element, and the characteristics of the efficiency is investigated by the combination of the adjustable stub with the high power sensor in the past developed. As a result of automatic adjustment of matching, it is found that the VSWR is improved to be in the region of 1.5_??_4.0 and the heating efficiency is increased by 3_??_21(%) for water of 100_??_300(cc) used as a practical load.
