Abstract :
Extensive measurements have been carried out in a straight road tunnel to study co-polar and cross-polar field behaviour versus frequency and antenna positions. The tunnel has approximately a semi-circular shape cross section that is quite usual for road and railway tunnels. Since MIMO techniques can be used for improving communication performances, even in tunnels, polarization diversity must be carefully studied for optimizing the antenna array configuration.
