Experimental Investigation Of Millimeter-Wave Multi-Path Propagation In Passenger Vehicles

This paper reports the measurement campaign and identification results of the millimeter-wave multi-path propagation characteristics at 61.5 GHz band in a passenger vehicle environment. Four measurement scenarios were assumed, and the propagation characteristics of the dominant paths in each were identified. From the results, it can be seen that the dominant paths are distributed along the line-of-sight (LoS) direction, but it could also be seen that some other communication links of which power are ranged from 10 to 15 dB smaller than that of the LoS component are available.
