Popis:	The research results of the amplitude-phase field distribution in the near-field zone of the broadband lens horn antenna, which is used in the bench for measuring the electromagnetic properties of materials in free space, are presented. It is shown that the installation of a lens in the horn antenna leads to an increase in the uniformity of the amplitude-phase field distribution in the working area of the measurement bench, which increases the quality of complex permittivity and permeability measurements.
