“…A PDE consists of multiple antennas at fixed locations on body, which results in a lower measurement uncertainty due to the variation of antenna location on body. A similar approach is used in [ 24 ] for the 60 GHz band. The proposed PDE in [ 9 ] has not been used outside the lab.…”

A multi-band Body-Worn Distributed exposure Meter (BWDM) calibrated for simultaneous measurement of the incident power density in 11 telecommunication frequency bands, is proposed. The BDWM consists of 22 textile antennas integrated in a garment and is calibrated on six human subjects in an anechoic chamber to assess its measurement uncertainty in terms of 68% confidence interval of the on-body antenna aperture. It is shown that by using multiple antennas in each frequency band, the uncertainty of the BWDM is 22 dB improved with respect to single nodes on the front and back of the torso and variations are decreased to maximum 8.8 dB. Moreover, deploying single antennas for different body morphologies results in a variation up to 9.3 dB, which is reduced to 3.6 dB using multiple antennas for six subjects with various body mass index values. The designed BWDM, has an improved uncertainty of up to 9.6 dB in comparison to commercially available personal exposure meters calibrated on body. As an application, an average incident power density in the range of 26.7–90.8 μW·m−2 is measured in Ghent, Belgium. The measurements show that commercial personal exposure meters underestimate the actual exposure by a factor of up to 20.6.

“…For multiple plane waves incident on the antenna, P r,sim is not necessarily equal to the sum of the incident powers induced by each single plane wave, since the incident plane waves can interfere with each other. Therefore, the P r,sim is calculated as a function of the incident electric fields (the sum of the induced voltages on the antenna) [9,13]. The phase, polarization, polar (θ) and azimuth (ϕ) angles of the plane waves are assumed to have a uniform distribution (from which 1000 samples are drawn for each parameter) in the range of [0, π] (θ and polarization) and [0, 2π] (ϕ and phase) [23].…”

For the first time, a mm-wave personal exposure meter (mm-PEM) for the 5th generation of mobile networks (5G) exposure assessment in indoor diffuse fields is presented. The design is based on simulations and onphantom calibration measurements in a mm-wave reverberation chamber (RC) at 60 GHz. The mm-PEM consists of an array of nine antennas on the body. Using the mm-PEM, the incident power density (IPD) is measured in the unloaded RC, for the antenna(s) on the phantom and RC loaded with phantom. The uncertainty of the mm-PEM is then determined in terms of its response, which is defined as the ratio of antenna aperture for the above measurement scenarios. Using nine antennas, the designed meter has a response of 1.043 (0.17 dB) at 60 GHz which is very close to 1 (0 dB), the desired ideal response value. The mm-PEM measured an IPD of 96.6 W.m −2 at 60 GHz in the RC, for an input power of 1 W. In addition, the average absorption cross section of the phantom is determined as 225 cm 2 , which is an excellent agreement with its physical dimensions.
