Abstract
The paper deals with some methods for relative permittivity of dielectric materials measurement and with the relevant techniques. In addition to current methods of measurement evaluation on vector network analyser our new approach gives also information about possibility of the use of classical methods for evaluation of application at vector network analyser as a faster source of basis for computations. In the paper also an attention to a situation is paid when it is problematical to determine the unknown permittivity of solid material by usual methods.
