Abstract

A microwave sensor is presented in this letter for the detection of salinity and sugar concentration. The microwave sensor is used for the transmission and reception of electromagnetic wave. The sensor has a circular shaped radiating patch with semi-circular shaped slots. The antenna sensor is prototyped on a low-cost FR4 substrate which is 1.60 mm thick. The sensor has a small size of 26 mm × 24 mm. The high-frequency structural simulator (HFSS) is utilized to model the microwave sensor. The sensor detects the salinity and sugar concentration by means of the reflection coefficient. The dielectric constant changes with the increased percentages of the salt and sugar which reduces the reflection coefficient. The microwave sensing device shows considerable sensitivity to determine the salinity and sugar concentration.
