Abstract

For the first time, a personal exposimeter (PEX) for 60 GHz radiation measurements is presented. The PEX is designed based on numerical simulations and both on-body and on-phantom calibration measurements to determine the antenna aperture and measurement uncertainty of the PEX. The measurement uncertainty of the PEX is quantified in terms of 50 and 95% prediction intervals of its response. A PEX consisting of three nodes (antennas) with VHH (vertical-horizontal-horizontal) polarization results in a 95% prediction interval of 6.6 dB. A 50% prediction interval of 1.3 dB (factor of 1.3) is obtained for measured power densities which is 3.1 dB lower than a single antenna experiment. The uncertainty is 19.7 dB smaller than that of existing commercial exposimeters at lower frequencies (<= 6 GHz).
