Numerical modelling calculations for evaluating exposure to radio-frequency emissions from base station antennas

The availability of reliable, simple procedures providing assistance in evaluating human exposure to radiofrequency fields from base station antennas is essential for mobile communications. In the paper, sample results of 'rigorous' full-wave numerical analysis of the electromagnetic field morphology in vicinity of a representative base station (BS) panel antenna are presented. Having recognized the field morphology, two simple approximate calculational models suitable for routine evaluation of exposure from BS antennas are examined and compared.
