Design and calibration of a 60-GHz personal exposimeter for exposure assessment in specular and diffuse environments

For the first time, a personal exposimeter (PE) for 60 GHz radiation measurements is presented. The PE is designed based on numerical simulations, on-phantom and on-body calibration measurements under specular and diffuse exposure to determine the antenna aperture and measurement uncertainty of the PE. A 95% prediction interval of 6.6 dB is obtained for the PE's response using a combination of three nodes with different polarizations. The response of the PE is in the range of 0.7 to 1.2 for specular and diffuse fields.
