Abstract:Based on the research on the measurement of electromagnetic parameters, through analyzing and improving
the traditional method, the phase shift ambiguity problem and the half-wavelength divergence were solved,
and finally a set of test system to test the electromagnetic parameters of common materials in the bandwidth from 2 to
18 GHz was built. Due to the restrictions of performance of antenna, the measure result is not accurate between 2 to
4 GHz and 14 to 18 GHz frequency range. This test method has the feature of fast, simple structure, convenient and
accurate positioning, high test accuracy and so on.
