UWB Power Penetration Inside a Realistic Human Head Model

In this paper, an antenna operating near a human head is analysed in the ultra-wideband (UWB) frequency range. The UWB antenna operating over a frequency range from 3.1 GHz - 6.7 GHz is evaluated in terms of reflection coefficient, E-field and H-field penetration, and specific absorption rate (SAR) of the human tissue when the antenna is operating in front of a realistic human head model. The study shows that at higher UWB frequencies, the power propagation inside the human head decreases significantly.
