Abstract
A mobile phone equipped with a multiple antenna system is investigated with respect to its human exposure to electromagnetic fields. The channel conditions and the demanded capacity determine the required exictation voltages, which are passed to a commercial software tool. To get rid of the influence of various antenna distances to the shaped human head a dielectric cuboid is considered as absorbing medium. Utilizing MIMO techniques with channel knowledge at the transmitter allows a reduction of the exposure by some 95%.
