Abstract :
Measurements in an anechoic room of three-dimensional radiation patterns for 44 test persons using a handheld phone with two antennas are investigated in order to find the bodyloss. The measured bodyloss range from 0.9 dB to 16 dB. From the measurements is was possible to separate the absorption and the loss due to mis-match of the antenna. The antenna mis-tuning accounted for less than 2 dB to the bodyloss. The uncertainties in the measurements is in the order of one dB
