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.
