Energetic Directivity Characteristics of the Linear Synchronous Antenna, Excited by the Ultrashort Impulse with Asymmetrical Exponental Fronts

Keywords:

A. A. Pokrovsky, M. I. Sugak


We calculate explicitly the radiation pattern for linear antenna with uniform distribution excited by a current pulse with exponential fronts. For a specific experimental form of non-symmetric exciting current pulse we demonstrate that our approximation is better for both the incident current pulse and the resulting energetic directivity than the approximation with the gauss-like pulse. We study the dependence of the directivity from the signal shape and the length of antenna. In particular, we consider symmetric and step-like pulses.
