Abstract

This paper compares the principal plane radiation patterns of a portable radio handset at 850 MHz computed with the finite difference time domain method with measured radiation patterns. The agreement for the handset in isolation is excellent. The computed patterns of the handset operating near a box model of the head are compared with measured patterns with very good agreement. Finally the computed patterns of the handset operating near a sphere model of the head are compared with measured patterns, with very good agreement, but not quite as good as for the box. The paper demonstrate the effect of simple head models on the radiation patterns of a vertical handset, and provides a validation of the FDTD computations
