An experimental study on the intensity of scattering wave by automobile body as multipath source in mobile communications

The measurement of the electromagnetic wave scattering pattern of a reduced automobile model by means of a microwave simulation experiment in an electromagnetic anechoic chamber is discussed. The results show that the maximum level of the automobile´s scattering pattern reaches -10 to -22 dB compared with the incident wave intensity. This indicates that when a mobile station is in a heavy-traffic city zone, the scattering from vehicles in the vicinity of the station must be taken into account as a source of multipath
