  Path loss is a significant component of wireless communication channel design
and analysis and reflects the reduction in a transmitted signal's power
density. Due to the differences in the propagation conditions, wireless aerial
channels' features differ from those of terrestrial wireless channels;
therefore, unmanned aerial vehicle path loss models are often different from
conventional terrestrial wireless channel path loss models. A mathematical
propagation model is proposed in this paper to estimate the Ground-to-Air path
loss between a wireless device and a low-altitude platform using the frequency
bands of the millimeter wave. The suggested model of Ground-to-Air path loss
will assist academic researchers in formulating several vital problems.
