Abstract. The article is devoted to the investigation of the spatial distribution of the electromagnetic field of the broadband horn P6-23 antenna in the near-field region. The amplitude and phase distribution of the electromagnetic field is measured by the two-dimensional electromagnetic near-field scanner at different distances from the antenna aperture. The measurements are carried out at two configurations: with and without lens. The numerical simulations of the near field distribution of the antenna are performed by the computational electromagnetics software package FEKO using the rigorous method of moments. Based on the obtained results the conclusions about possible restrictions of the investigated antenna as a part of a measurement system are made. The antenna modernization by coating of the inner surface of the horn walls by a thin layer of the broadband radar absorbing material is proposed. It is demonstrated that the modernization provides the significant reduction in the non-uniformity of the near-field amplitude distribution in a wide frequency band from 4 to 15 GHz. It is demonstrated that the area with the appropriate non-uniformity is increased on 10-30% depending on frequency.

Key words: wideband antennas, microwave scanner measurement, numerical simulation, FEKO, method of moment.
