Fields in bicone line and in free space are presented in the form of expansion over frequency-independent modes. Each mode possesses the dispersion depending on radius. With the mode matching method, the bicone antenna pulse radiation is calculated. It is shown that introducing some dielectric layer improves the antenna characteristics and allows to obtain the radiated field with higher amplitude.Key words: biconical antenna, frequency-independent modes, dispersion, mode matching method, time domaiManuscript submitted 27.02.2015Radio phys. radio astron. 2015, 20(2): 133-141 REFERENCES1.  SCHANTZ, H., 2005.
