Abstract

Accurate measurement of characteristic impedance of coaxial lines is widely researched since it is as microwave impedance and scattering-parameters standard. A new time-domain measurement method terminated load is proposed to measure the characteristic impedance of coaxial lines. The measurement results can be traced to the physical parameters such as geometric quantity. The method proposed can be used as a standard for measuring characteristic impedance of coaxial lines, which validity verification values En<1.
