Simplified hand model for the study of hand-held device antenna

This paper proposes a one-layer simplified hand model incorporating the use of 3D FDTD simulation software, SPEAG SEMCAD-X (simulation platform for EMC, antenna design, and dosimetry) for achieving efficient simulation for hand-held device antennas. The case of the GSM/DCS internal mobile phone antenna with the proposed hand model is first presented. Effects of the proposed hand model including the user's forearm on the impedance and radiation characteristics of the internal antenna are analyzed. A second case of the DTV antenna in the PMP device with proposed hand model is also studied.
