Additional methods of analysis are considered. It is shown that reducing
three-dimensional conic problem to the two-dimensional one and using the complex
potential method enables one to calculate the capacitance per unit length and the wave
impedance for a dipole with inclined arms and also the same for an infinite long line
and a metal radiator of two convergent filaments or conic shells. The theory of
electrically coupled lines permits analyzing multiple-wire structures of antennas and
cables. The mathematical programming method allows selecting the loads to create an
antenna with the characteristics as close to the given one as possible. The compensation
method is proposed to protect living organisms and electronic devices from strong
electromagnetic fields in the near region of an antenna.
