Qualitative Analysis of Elementary Antennas Impulse Radiation

The aim of this paper is to study the non-stationary structure of simple antenna fields (the electric dipole, the vibrator, the system of dipoles) with the help of the qualitative theory methods for the ordinary differential equations (ODE). The qualitative analysis is of interest because numerical research meets the certain difficulties in vicinities of the vector field critical points, and qualitative methods are effective in these cases in particular. Therefore the combination of qualitative and numerical methods is the most expedient and economical approach in the analysis of electromagnetic fields. The strategy of qualitative theory application to the analysis of pulse fields of simple antennas in free space, and also the results in this area received to the present time are discussed
