摘要

For measuring the effective is a direct and / or of the effective source port - adaptation of a gate (m) of a system calibrated vector network analyzer (n) is a short-circuited at the output of the dosed - air line (l) is switched on and the complex reflection coefficient at the input of this toothed - air line (l) at a series of measuring points measured within a predetermined frequency range. In this case, for the effective direct the sequence of measured complex reflection coefficients, - a discrete fourier transformation and from the resulting spectrum is filtered out of the baseband. By subsequent inverse fourier - inverse transformation, the sequence of effective directivity - values obtained.
