The purpose is to present metamaterials in a general way as many researches do not provide general background and knowledge, and focus on very specific uses and topics. As many researches focus on the use of metamaterials with antennas, the second objective is to analyze if they could possibly improve the performances of antennas. Thanks to FDTD simulations, several configurations have been investigated. The effective reduction of the fields thanks to metamaterials is investigated because improving user`s safety compliance and handset performances is a major interest of mobile phone designers.
