要約(英語): A novel 60 GHz band exposure set-up has been newly developed for studies on thermal thresholds of biological effects of humans exposed to millimeter waves (MMW) that are 5th generation wireless systems (5G) and beyond-5G candidate frequency bands. To achieve high duty exposure to 60 GHz at the desired area, the authors proposed a spatial synthetic beam-type exposure set-up consists of dielectric lens antennas that can irradiate focused beam. We applied orthogonalizing polarized feeding structure to eliminate interference fringes generated in the exposure area due to the combined two-directional beam radiations. Using FDTD simulation, electromagnetic fields distributions on the exposure area due to incident angles of the combined beams was estimated. In order to obtain exposure characteristics, we achieved exposure experiments of temperature rise measurements using a physical arm-shaped skin phantom and human forearm. The developed set-up enabled efficient and desired exposure control for the experiments to explore the biological effects of local exposure to MMWs on human volunteers.
