Parasitic Effects

The analysis, approximations and accounting of the influence of the main parasitic effects that affect the results of the measurement are provided in this paper. The method of dielectric constant measurement of coaxial connectors support beads is suggested. The comparison between the acquired results using the suggested method and the reference is made. The results suggest that the method can be used for dielectric constant measurement of the coaxial connector support beads with the accuracy comparable to the method of the volume resonator for rod samples H01p by GOST 8.623-2015.

Dielectric Constant Measurement

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.
