This study assesses human exposure in the close vicinity of mobile phone base station antennas by FDTD simulations. The peak spatial average and whole-body average SARs were analyzed with respect to the basic restrictions for occupational exposure in three different anatomical models (55–101 kg), at distances between 0.5 and 4 m, from various antenna types operating at frequencies ranging from 450 to 2140 MHz. The results demonstrate that the whole-body absorption generally determines the maximum permissible antenna output power for collinear array antennas. However, local exposure depends on various effects that fluctuate strongly among individuals and the peak spatial average SAR can be more restrictive than the whole-body absorption. Therefore, compliance must be demonstrated for both quantities.
