Errors of measuring antenna parameters in the field of a non-plane wave in the presence of a cross-polarized component

摘要

Expressions for calculating the errors of measuring the antenna directional characteristics caused by the irregularity of the amplitude-phase distribution of the Illuminating field and the presence of a cross-polarized component in it are obtained. The application of these expressions is illustrated by calculating in the error of measuring in the field of a real collimator, which was fixed by a high-precision measuring system.
