| Abstract(in English) | The residual directivities in vector network analyzer (VNA) calculated by the ripple technique were verified referring to the result of the evaluation in vector value (vector-evaluation). As a result of calculating the residual directivities by the vector-evaluation using two types of air line, i.e. beadless and beaded air lines, the both results agree well within the range of the air line S-parameters uncertainties; 0.002-0.004. The residual directivities calculated by the ripple technique using the beaded air line were larger than those obtained by the vector-evaluation. Because the characteristics of the air lines and the residual directivities cannot be separated out in the results of the ripple technique, the beaded air lines having large S_<11> characteristics cannot be used in ripple technique for residual directivity evaluations. |
