EM Wave Exposure Antenna for Animal Experiments in 26.5 GHz

In this days, the next generation wireless communication system such as 5th generation mobile communication is developed. In the system, higher frequency band such as 28 GHz will be used. On the other hand, mobile devices such as smartphone are used in the vicinity of a head in a talking mode, therefore, some EM wave exposure to a human head will be local exposure. In order to evaluate the positive effecton human health, an animal experimental study is necessary. In order to realize local exposure during mobile phone using for the animal experiment, an EM wave local exposure antenna is required. In the animal experiments, electromagnetic wave energy absorption should be focused on a head region of laboratory small animals. In this paper, our developed local exposure system including an antenna for the animal experiment is reported. The working frequency of this system is 26.5 GHz.
