Abstract
The great majority of wireless devices are used close to the human head. These changes the antenna performance compared to free space situation. The human head absorbs an amount of power from the antenna radiation. In this sense, it is important not only to increase the robustness of the antenna performance, but also to reduce the amount of power absorbed by the human head. A coupled monopole and a PIFA antenna are evaluated in terms of antenna performance in presence of the human head. The most significant parameters (SAR, efficiency and return losses) are obtained at two different positions of the antenna as a function of the frequency band, to finally evaluate the impact of the human head to the antenna performance, and the effect of the antenna on it. Despite both antennas have a similar efficiency value at Free Space, monopole antenna has more sensitivity to the interaction with the human head.
