Broadband Measuring of Shielding Covers

Abstract

The novel method utilizing coupled lines for the dielectric property measurement of shielding covers of composite materials is described. Characteristics of coupled lines designed by two symmetrical strip lines with a common side wall, which is made of the tested material, are mentioned. It allows measuring the dielectric property in the frequency range up to 5 octaves. The circuit analyzer with a high dynamic range is used for parameters evaluation. The method was utilized at the research of the technology of abnormally shaped shielding covers of composite materials.
