Summary:
The applications of radio and TV broadcasting often operate at a frequency range below 100 MHz. The receiving antennas of the terminal are generally mobile and may move from a location to another. In particular, as the receiving antennas move into a tunnel environment, the signals will experience degrade and result in poor reception. Thus it is desired to study the radio wave propagation characteristics along the tunnel environment and seek for solutions that may improve the signal reception, which motivates the works presented in this paper. A numerical study based on method of moment (MoM) is thus performed to investigate and compare the signal levels for various situations of tunnel environments and antenna related parameters. Comparative results will be presented. And make two small scale tunnels to measuring simulation result.
