Tea leaves moisture measurement and prediction using RF waveguide antenna

This paper proposed a microwave reflection method by using a horn antenna at 10.3GHz to determine m.c. of tea leaves from 0% to 10.5%. The tea leaves are filled inside an acrylic container whereas a horn antenna is placed on the open ended of the container. Reflection coefficient, S 11 is collected...
