This paper describes, for the first time, the procedure for the full design, calibration, uncertainty analysis, and practical application of a personal, distributed exposimeter (PDE) for the detection of personal exposure in the Global System for Mobile Communications (GSM) downlink (DL) band around 900 MHz (GSM 900 DL). The PDE is a sensor that consists of several body-worn antennas. The on-body location of these antennas is investigated using numerical simulations and calibration measurements in an anechoic chamber. The calibration measurements and the simulations result in a design (or on-body setup) of the PDE. This is used for validation measurements and indoor radio frequency (RF) exposure measurements in Ghent, Belgium. The main achievements of this paper are: first, the demonstration, using both measurements and simulations, that a PDE consisting of multiple on-body textile antennas will have a lower measurement uncertainty for personal RF exposure than existing on-body sensors; second, a validation of the PDE, which proves that the device correctly estimates the incident power densities; and third, a demonstration of the usability of the PDE for real exposure assessment measurements. To this aim, the validated PDE is used for indoor measurements in a residential building in Ghent, Belgium, which yield an average incident power density of 0.018 mW/m².
本文首次描述了一种用于检测全球移动通信系统（GSM）下行链路（DL）频段900MHz附近（GSM 900 DL）个人暴露情况的个人分布式暴露计（PDE）的完整设计、校准、不确定度分析及实际应用程序。该PDE是一种由多个佩戴在身体上的天线组成的传感器。利用数值模拟和在消声室中的校准测量对这些天线在身体上的位置进行了研究。校准测量和模拟得出了PDE的设计（或身体上的设置）。这被用于在比利时根特进行的验证测量和室内射频（RF）暴露测量。本文的主要成果包括：第一，通过测量和模拟证明，由多个身体上的纺织天线组成的PDE在个人射频暴露测量方面的不确定度将低于现有的身体上的传感器；第二，对PDE进行了验证，证明该设备能正确估计入射功率密度；第三，展示了PDE在实际暴露评估测量中的可用性。为此，经过验证的PDE被用于比利时根特一栋住宅楼的室内测量，测量得出平均入射功率密度为0.018mW/m²。
