Abstract
The use of a mobile terminal in the close proximity of a human phantom is investigated. The performance of the transmitter, together with the energy dissipated in a human model is examined, by applying the Finite Difference Time Domain (FDTD) method. A correlation between the variation of the specific absorption rate (SAR) induced in the phantom and the values of the standing wave ratio (SWR) of the transmitter antenna, while the distance between antenna and phantom is altered, is examined using regression theory. A correlation between the variation of SAR and the distance between antenna and phantom as well as between values of SWR and distance is also demonstrated. Measurements conducted in an anechoic chamber verify the validity of the theoretical results.
