Local exposure antenna for small animals in 6 GHz – 10 GHz range

Mobile communication devices including smart phones are used in the vicinity of the human head, resulting in localized exposure to this part of the body. To simulate exposure during cellular phone use, microwave energy absorption should be focused within the head region of laboratory animals. On the other hand, it is expected that the use of UWB (6 GHz – 10 GHz) communication systems to expand. In this paper, we propose a head local exposure antenna simulate localized exposure of small rat to UWB (6GHz – 10GHz) microwave radiation. We have numerically estimated the specific absorption rate (SAR) in a rat exposed to microwave field radiation. The high ratio of SAR averaged over the target tissue (i.e., the brain) to that averaged over the whole body suggests that the antenna can realize.
