Imitation modeling of radiation of ultra short pulses by Horn antenna and evaluation of the energy efficiency of radiators on their basis

Software has been developed for automating the process of modeling ultrashort pulse radiation by broadband horn antennas. The influence of the duration of unipolar and bipolar voltage pulses exciting the antennas on the energy efficiency of their radiation is studied. It has been established that for each radiating antenna, regardless of the shape of the excitation pulse, there is approximately the same duration for which the maximum energy is radiated into space. It is shown that for equal energies of voltage pulses exciting antennas, the energy efficiency of radiation of bipolar pulses is higher than that of unipolar pulses.
