An accurate simulation of the radiation performance of a commercial CAD-oriented slide mobile phone, taking into account the influence of the SAM (specific anthropomorphic mannequin) head and hand, is presented. The simulation was performed using the commercial software SEMCAD, which is based on the Finite-Difference Time-Domain (FOTO) Method. The radiation effect on the SAM head and hand close to the phone was also investigated. Throughout the numerical simulations, the return loss, the radiation efficiency, and the near-field distribution of the mobile phone could be obtained, and thus the impact on the human body could be estimated. The slide phone was measured under different conditions. Numerical results were compared with the measurement data, and good agreement was obtained.
