Abstract

This paper presents a simplified model of a terminal mobile where a monopole antenna is associated with three different metamaterials: artificial magnetic conductor (AMC), electromagnetic band gap and resistive high-impedance surface (RHIS). The objective is to evaluate what is the metamaterial which is the best solution to reduce exposure. The exposure has been evaluated using a simplified phantom model. Results show that both AMC and RHIS reduce the exposure preserving the antenna performances. A reduction of 23 % of specific absorption rate 10 g has been obtained when the monopole is associated with an optimized RHIS structure. Antenna with and without metamaterials has been realized. The experimental results confirm the performances given by simulation in terms of impedance matching and radiation.
