Popis: This paper discusses the human head modeling for the design of handset antennas at 5GHz band. The effect of the human head heterogeneity and shape on the antenna characteristics is investigated thoroughly. In addition, an attempt is also made to realize a compact structure for the human head model. For this purpose, the radiation characteristics of a dipole antenna in the presence of several head models are compared. The numerical investigations reveal that the effect of the heterogeneity and shape of the human head model on the antenna characteristics at 5GHz band is marginal. Particularly, reasonable result can be obtained even for a model of rectangular parallelepiped with the dimensions (24 mm thickness × 120 mm × 120 mm). This volume is 96% smaller than the original realistic model.
