Analysis of on-body propagation at W band by using ray tracing model and measurements

The propagation between a transmitter (TX) and a receiver (RX) operating at 94 GHz, located in proximity of a human body, is investigated in this paper. The TX is positioned near the head and a line of RXs is located on the left shoulder. The high frequency method of ray tracing has been used to simulate these links. The simulated Path Loss (PL) has been compared to measured data. The agreement between simulations and measurements supports the possibility of using ray-based method to correctly predict the PL at millimeter wavelengths.
