Realistic human exposures to radiation emitted by a mobile terminal connected to either a 5G network (sub-6 GHz) or to a 4G network have been scarcely assessed till now. Present experimental work aimed at comparing the radiated field in air, in a sin

To gain a deeper understanding of the hotly contested topic of the non-thermal biological effects of microwaves, new metrics and methodologies need to be adopted. The direction proposed in the current work, which includes peak exposure analysis and n

The paper proposes the use of MATLAB simulations as a first step in identifying proper antennas to be used in specific ultra-high frequency (UHF) communication links. Giving that fractal antennas provide interesting features, we aimed at comparing a
