Using a pair of phased antennas to improve UHF reception transmission in tunnels.
UHF propagation inside tunnels improves considerably if a pair of phased antennas is used as a fixed antenna system, instead of a single antenna. In this article, we have analyzed the causes of signal deterioration in a tunnel due to slow fading and fast fading. We obtained simple relations for thei...
