The distortion of complex amplitudes of incident waves in the radiating channels of the linear antenna array, which is include radiators and a power division network without connectors, in the absence and presence of a multi-element probe device located in its near zone is considered.

Aim of article is identification of the properties of a lossless passive beam forming network loaded on the radiating system of interacting antenna elements, which are important for the construction of the stand for measuring the amplitude-phase distribution of incident waves in radiators channels of linear antenna array by the multi-element probe method.

A mathematical model of linear antenna array with a passive beam forming network that forms equal phase distribution of outputs and distribution with small phase deviation is obtained. A comparison of beam forming network with not matched and matched power dividers is carried out.

The results obtained can be used in the construction of stand designed to measure and restore the linear antenna array amplitude-phase distribution and assess its resulting measurement error.
