This paper propose a microstrip moisture sensor based on microwave measurement technique. Sensors with low insertion loss were developed to operate with a frequency range from 1 GHz to 3 GHz. The variations in percentage of moisture with magnitude and phase of transmission coefficient were investigated by using
the different techniques.
Keywords: Moisture sensor, CST, Vector network analyzer, reflection coefficient, rectangular antenna.
