Antenna/human body interactions in the 60 GHz band: State of knowledge and recent advances

Abstract : In this chapter, we presented a review of the state-of-the-art, recent advances, and remaining challenges in the field of antenna/human body interactions in the 60 GHz band, with a particular emphasis on the near-field interactions that may occur in emerging body-centric MMW applications. For new near-field exposure scenarios expected to appear in coming years, today there is no any clear regulation in terms of the exposure assessment, and standard methodologies for compliance testing are not available in the 60 GHz band. Most of the exposure guidelines and standards recommend IPD as a dosimetric quantity. It cannot be directly used as a metric for near-field exposures since practically it is very challenging, if not impossible, to determine numerically or experimentally local IPD under near-field conditions. Some reports suggest that temperature rise could be used as an exposure metric at MMW. However, in practice, it is not always possible because of some limitations discussed in this chapter. We suggest to use eIPD as a metric; it can be conveniently retrieved from SAR computations and/or measurements and takes into account the perturbation of the wireless device radiation due to the body proximity. © The Institution of Engineering and Technology 2016.
