Broadband Isotropic Magnetic Field Probe to assess Human Exposure in the 5G FR1 band in Colombia

In this paper we present the design and evaluation of an isotropic magnetic field probe to assess the broadband contribution of the magnetic field to human exposition within the FR1 band foreseen for the deployment of the 5G technology in Colombia. This device complements the current practice in this band, based on the measurement of electric field only, which may underestimate the overall exposition in the near field of particular sources or scatterers. The frequency response of the magnetic probe is designed to correctly weight the various frequency components according to the ICNIRP 2020 guidelines, and takes into account the detailed frequency response of all the system components including the elementary sensor and the power detector. The performance of the resulting design in isotropic configuration is validated.
