Abstract
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, S11 is collected and its relationship between gravimetric (m.cg) and volumetric moisture content (m.cv) are fitted in two polynomial equations respectively. The equations are used to predict m.c. of tea leaves. The maximum error for the predicted m.cg is 0.52% whereas the maximum error of predicted m.cv is 0.233%.
