A method and formulae for correction of the sidelobe level of the radiation pattern of a high gain antenna when measured in the Fresnel region are presented. After a thorough analysis of a large number of different cases, trend curves have been computed and an empirical formula has been derived, which allows the correction of the measured values of the sidelobes when the measurement range is below or around the far‐field distance.
