Abstract :
The paper investigates the time constant of temperature increase in human head models due to a dipole antenna. The frequency band considered is from 900 MHz to 2.5 GHz. In order to discuss this problem thoroughly, hundreds of cases are considered: five frequency bands; two polarizations; two head models, with pressed and impressed ears; ten antenna feeding points. The results provide useful information in this field.
