摘要：

An equivalent circuit for coaxial discontinuities is presented and discussed. The cell used is a circular waveguide filled with a dielectric material measured in reflection/transmission. The circuit is obtained by using two well known methods: the Marcuvitz's circuit for a cell measured in reflection and an analytical resolution using the mode-matching method. The interest of the new circuit is that it has wider frequency and geometrical ranges than the Marcuvitz's circuit and is much simpler than the mode-matching method. Using this circuit, complex permittivity can be calculated from measurements of the S-parameters (S-11 and S-21). Experimental results are presented up to 18 GHz. Frequency and geometrical ranges of validity are also discussed.
