A simple directional path loss model for a terminal inside a car

Measurements of the radiation from a /spl lambda//2-dipole antenna inside a common car was compared to calculations at 1.9 GHz, to establish a principal knowledge of the radiation mechanism related to a vehicle such as a car. Based on this a new simple directional path loss model is proposed, that uses minimal knowledge of the vehicle's geometry. This model may be well suited for simulations of mobile communication systems when the terminal is placed inside cars or other similar vehicles.
