Measurement on the Dielectric Constant of Grass with Rectangular Waveguide at C Band

Abstract:

This paper was developed by microwave measurement on the vegetation dielectric constant through using the rectangular-waveguide at C Band. The measurement system and the method of the measurement will be introduced in detail. We have a standard block of known dielectric constant measurement, and then evaluate the error range. The system of measurement error range is ± 5%.At last, the result of this experiment showed that different density corresponds to different dielectric constant in the case of certain moisture content, and the dielectric constant increases with the density.
