Research on the Radiation Characteristics of Leaky Coaxial Cable and Spiral Antenna in the Blind Zone
As an instrument to realize mobile communication in the blind zone, leaky coaxial cable (LCX) is recently widely used in communication systems of tunnels, mines, subways and so on. In this paper, beginning with the radiation theory of LCX and antenna, by the use of ray-tracing method, we take a tunnel for example to analyze its radiated field produced by both LCX and spiral antenna. By comparison, LCX shows advantages in the coverage of the radiated field in such special areas—the distribution of the radiated field is more uniform. The theories and results in this paper can be extended in other blind zones and have referenced values in further research on solving the problems of communication in the blind zone.
