Abstract :
A lightweight phantom is made by a plastic shell with a shape of the human head and it has a cavity inside. The cavity is filled entirely or partially with the absorbers. In the next section, we evaluate the characteristics of the phantom with a dipole antenna near a COST244 spherical model imitating the human head. The radiation patterns are measured in experiment, and the phantom is compared with the real human head. The paper investigates the shape of the human head model to improve accuracy of simulation.
