Abstract This paper describes about magnitudes of the time domain and frequency domain measurement errors of the near-field antenna measurement systems with planar scanning are available for correct directivity antenna measures. The results are obtained by near-field/far-field simulate programming for pulse characteristic measurement errors and complex amplitude measurement errors. In this paper are shown how to obtain required accuracy ± 1,2 dB in case measuring of minus 40 dB level side lobes of antennas directivity pattern by ultra wideband and narrow-banded near-field measurement systems. For this requiring the amplitudes uncertainty are 1,5 % and time characteristics uncertainty are 4,5 % for ultra wideband measurement systems are obtained.
