Annotation. Using the developed mathematical model of measurements on antenna measuring complexes of the near zone, the uncertainties of measurements external characteristics of antennas: of the gain, amplitude and phase angular patterns, the level of cross-polarization and the coefficient of ellipticity were estimated. The connection between measurement uncertainties external characteristics of antennas and the uncertainty of reconstructing the electromagnetic field in the far zone is investigated. A method is proposed for expressing the measurement uncertainty of all external characteristics of antennas through a single characteristic — the equivalent level of interference.
Key words: antennas, uncertainties, gain, amplitude and phase angular patterns.
