The circular microstrip patch sensor based on oven drying technique for detecting the moisture content of rice grain. The circular microstrip patch sensor is designed at 6GHz with the good return loss -28dB and gain 3.41dB as well as low insertion loss. The sensor is designed with using FR4 (lossy) substrate with εr = 4.3 permittivity and h= 1.6mm thickness. The outer and inner radius of circular patch sensor is 14.5mm and 13.5mm respectively. A 50 ohm SMA female connector will be used as the feeding port of the microstrip on the fabrication and measuring time and measured the moisture sensor by using the vector network analyzer.
Key-words: circular microstrip patch sensor, rice grain, moisture content, oven drying technique.
The superiority of rice grain brings on a high demand in the India as well as especially in Asia [1-4]. The price of rice is getting costly and due to the moisture of rice percentage is going down so it is very important to protect the rice. The circular microstrip patch sensor is detected the moisture content of rice at 6 GHz. The Various techniques have been designed for detecting the moisture content of rice [5-7]. An annular photoelectric sensor was also used to determine moisture content of rice grain by applying the Lambert’s law. Recently, microstrip antennas have been widely used in many applications such as communications, medical and agriculture [8-12]. The objective is to establish the relationship between reflection coefficient of the sensor and moisture content in rice grain
