Abstract

From a theoretical point of view, tunnels may be regarded as oversized lossy waveguides and field distributions inside them are calculated by the waveguide theory. However, it is difficult to include the radiation pattern to investigate a near region of a source. In this study, the field distributions inside tunnels including a source were investigated using the ray-tracing method. In the calculation, it was found that the optimal antenna pattern to increase the coverage area is nearly sin3θ when the beam width is changed and the beam direction is directed along the guide.
