Com pared t he simulation result wit h t he vector network analyzer in the reflection coefficient and p hase picture result , t he error is less than 8 %. It was found that t hey are coincided wit h each ot her very well . It is p roved t hat the met hod p resented here is p ractical and u seful . The error of t his measurement is discussed. Then studying the waveguide tube relative po sition of t he microwave oven to t he matching performance of t he microwave oven . These p rovide an engineer t heoretical guiding during t he period of cold matching of microwave oven , curtailing develop ment time of microwave oven new platform , t hen imp roveing competition .
