This article presents a study of the impact of finite-radius wire antennas in the High Frequency (HF) and the Very HighFrequency (VHF) bands on human operators located in the near-field zone. Modeling a finite-radius wire antenna can be a verytricky task, since the antenna parameters, such as the input impedance and the radiated power depend on the wire's shape andthe air-gap, as well as its length and the input power source. However, to accurately model the wire shape and the air-gap a veryfine resolution is normally needed since they are normally very small in size. In a nutshell, this article studies the impact of thepreviously mentioned antenna parameters on the Specific Absorbed Rate (SAR) distribution in humans and some possibletechniques to speed up the simulation process
