METHOD OF MEASURING S-PARAMETERS OF OBJECTS IN NON-STANDARD GUIDE SYSTEMS Russian patent published in 2019 - IPC G01R27/06 

FIELD: measuring equipment.

SUBSTANCE: invention relates to UHF measurement equipment and can be used to determine S-parameters of devices and electronic components in non-standard transmission lines and flat objects in free space. Method involves connection of two transitions by non-standard electrically long transmission line of length L and measurement of parameters , determination of reflection coefficients from coaxial connectors, connection of each transition with a section of a line with length L/2, forming chains a and b, short-circuited or open at the end, and measurement of reflection coefficients on side of coaxial connectors, determining parameters of chains a and b

and switching on the measured object between circuits a and b, measuring parameters of connection S₁₁, S₂₁, S₁₂, S₂₂ and determining parameters of object from ratios .

EFFECT: high accuracy of measuring S-parameters.
