Abstract

A wide range of microwave devices, particularly those intended for use in telecommunication systems, are manufactured using printed circuit board technology. Designing such devices requires precise knowledge of the properties of the dielectric plates used. In this article, the authors propose a very easy-to-manufacture measuring device that combines the nondestructive testing inherent in the free space method with the ability to achieve the accuracy of the resonance method. Two factors provide the advantages of the proposed installation: the peculiarities of the plates' geometric structure and software processing of the measurement results. One- and two-port designs are considered, and the features of the corresponding algorithms for processing measurement data are investigated. The results of electrodynamic modeling of strip-line fixtures in the CST Studio Suite environment confirm their operability and the possibility of providing sufficiently high sensitivity when measuring the complex permittivity of plates made of various materials. Areas for future research are discussed.
