Development of 28 GHz band exposure equipment for studies on thermal perception thresholds of biological effects exposed to millimeter-wave at 5th generation wireless systems candidate frequency band

摘要

Authors developed a radio-wave exposure equipment for studies on thermal perception thresholds of biological effects exposed to millimeter-wave at 28 GHz band that is 5th generation wireless systems (5G) candidate frequency band. To achieve high duty RF exposure on living body at 28 GHz required, we newly designed a lens antenna that can irradiate focused beam. In order to obtain basic exposure performance of the developed equipment, we used physical phantom that simulated human's skin and achieved exposure experiments of temperature rise measurements during at 28 GHz band millimeter-wave exposure.
