“…Some previous studies have aimed to mitigate these effects through parametric optimization [2], ground plane current reduction [3], and adaptive matching [4]. However, there is no method to design antennas in the presence of lossy dielectrics that shows where, and how, to place antenna feeding elements to obtain low correlation and high efficiencies.…”

Abstract-Although the classical Theory of CharacteristicModes allows an arbitrary structure to be analyzed prior to the implementation of physical feeds, structures containing dielectrics have so far received very little attention. Recently, a mesh perturbation method is proposed to remove internal resonances from the characteristic mode (CM) solution for lossy dielectrics obtained using the computationally efficient surface integral equation. Herein this method was applied to extract the CMs of a lossy structure consisting of a terminal chassis held in a user hand. These modes were then individually analyzed and a subset was chosen to design a MIMO antenna with not only very low correlation, but also low hand-induced losses.

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.
