Monopole antenna technique for determining moisture content in the Dioscorea hispida tubers

This study demonstrates the determination of moisture content in D. hispida tuber using microwave technique. A network analyzer was used to measure the reflection coefficient of a monopole antenna inserted in D. hispida tuber at different percentage of moisture content. The actual moisture content o...
