A skin-based phantom is used to numerically model on-body propagation at three different frequencies, 2.4, 24 and 60 GHz. Linearly-polarized open-ended waveguides are used as antennas. The influence of polarization on path gain and antenna radiation efficiency are analyzed. The results show that path gain is highly sensitive to the antenna/body separation at 24 and 60 GHz.
