The development of exposure devices for investigating possible effects of mobile communication systems to nonrestrained animals aims at a homogeneous field distribution in the area the animals occupy. In the presented 900 MHz exposure device based on a modified rectangular waveguide (WR1150) a quite good field homogeneity of 5 % (including the standing wave contribution due to internal reflections) is reached in the cage region mainly by flattening the transverse field. The desired maximal whole-body specific absorption rate (SAR) of 4 W/kg in the Djungarian hamster model is achieved at an input power of only 3.7 W.
