Now-a-days, microstrip antenna is an important tool for wireless networks. Frequency sensitive antenna by using DGS at 2.39GHz and by using non DGS at 1.96GHz is being proposed. This paper represents microstrip sensor by using a triangular patch antenna using Defected Ground Structure (DGS). It is used for high quality rice measurement. By using DGS and without DGS a percentage of minimum and maximum moisture content is determined at different frequencies. It is designed on FR4 substrate which is simulated in CST software after that hardware has been fabricated on printed circuit board and the return loss is measured by using spectrum analyzer.
