Resum
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 muW.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.
