Research on the Radiation Field of Wide-Band Leaky Coaxial Cable

Recently, leaky coaxial cable plays a more and more important role in every kind of blind or semi-blind zone mobile communication, and along with the increase of communication business, the number of frequency band increases, lager communication capacity is needed, so it is necessary to extend the frequency band of leaky coaxial cable. The method of extending the frequency band of leaky coaxial cable is studied in this paper, and the radiation field of leaky coaxial cable whose frequency band is extended is simulated, the results show the relationship between band extending and radiation characteristics.
