Paper Abstract

An application of multiline method in measuring the effective dielectric constant of micromachiend microwave transmission lines is presented in this paper. This multiline method does not need a network analyzer calibration. It produces the effective dielectric constant of the structure using propagation constant measurements. For comparison, we performed measurements in micromachined microwave transmission lines both before and after they were suspended. The measurement result show that at high frequency the real part of the effective dielectric constant of the structure is about 6 before suspending and is about 1 after suspending. The imaginary part of the measured effective dielectric constant of the structure is about zero because the transmissions line is very short.
