Abstract
A method for evaluating the measurement error of the dielectric constant by the transmission line method is considered. In this paper, the main sources of error are determined by the errors in measuring the reflection and transmission coefficients using a vector network analyzer. The Nicholson-Ross-Weir method is used to calculate the complex permittivity. The calculation of the error in determining the real and imaginary parts of the dielectric constant in a wide frequency range is shown. The proposed method allows to determine with high accuracy the boundaries of uncertainty when conducting an experimental study of a material sample.Keywords
