Paper Abstract

Precision through-lines, coaxial airlines, are the most accurate microwave impedance standards. They are widely applied in the TRL calibration method. The air-lines are also important standards which are used to test network analyzer systems. In addition, the scattering parameter and uncertainty of coaxial air-line are important for improving the accuracy of VNA. However, the conventional microwave measurement systems have limitations in observing and obtaining accurate information of the performance of coaxial air-lines. In this paper, a new approach is proposed that determines microwave scattering parameter by physical components and assumed models. Experimental results demonstrate the efficacy of the proposed algorithm in comparison to the experimental results obtained from microwave measurement. In addition, the estimated uncertainty is also presented.
