Analysis and Optimal Design of a Microstrip Sensor for Moisture Content in Rubber Latex Measurement

The analysis and optimal design of a microstrip sensor for measuring the water content of rubber latex is described. The microstrip structure consists of one layer: substrate, protective layer and semi-infinite layer of wet medium. A functional relationship has been developed between the attenuation and the water content of the latex, and close agreement has been found between the computed and experimental results. A computer program has also been developed which optimizes the sensitivity for given water content. As well as the calculated values of attenuation and Dielectric Loss and dielectric constant and effective dielectric constant.
