Estimation of Aperture Antennas Near-Field with Mutual Coupling Consideration

This paper presents the results of a theoretical analysis of the antenna characteristics main dependences on the amplitude and discrete phase-type distributions in the near radiation zone of an aperture antenna. The relevance of near-field studying is confirmed by the need for effective estimation of parameters and signal resolution, which is possible due to the accurate determination of the amplitude and discrete phase-type distribution in the aperture antenna or antenna array. The scientific novelty of the obtained analytical dependences consists in the possibility of developing a strict and well-founded approach to the extended interferometric array analysis on the example of numerical calculation of the field structure in the Fresnel and near-zones.
