Vehicle Antenna Position Dependent Path Loss for Millimeter-Wave V2V Communication

In this paper, we analyze the effects of the positions of a millimeter-wave (mmWave) antenna on a vehicle for typical vehicle-to-vehicle (V2V) scenarios. Propagation does neither effectively penetrate nor diffract around vehicles as the wavelength becomes shorter, the positions of an antenna on a vehicle is a crucial question. Path loss measurement was performed at 28 GHz in an open space to minimize the effect of the surrounding objects. Based on the measurement, we investigated path loss characteristics for various transmitter and receiver positions.
