This paper presents methods of backpropagation used to determine the near-field of telecommunication antennas. In few words, the backpropagation techniques employ special transformations to extrapolate the near-field of an antenna from its far-field. The far-field pattern is always measured and provided by the constructors. On the contrary, the process of near-field measurements presents some difficulties...
Antennas are sources of electromagnetic radiation. The radiation pattern and gain can be routinely obtained by measurements and characterize efficiently the radiation of the source regardless of its actual complexity. However in some applications, one may need to analyze the source interaction with its close environment in the near field region instead of the far field one. In this paper, we partition...
This article presents an innovative way to derive a radio station antenna model that can match very closely real antennas described by their measurements. The derived model can then be used for the assessment of human exposure to the electromagnetic field in the vicinity of the antennas, including the near field and the interactions with the environment. The technique is based on the principle of...
