The Method of Auxiliary Sources for antenna synthesis problems

Based on the Method of Auxiliary Sources (MAS) by means of the scattered field singularities localization antenna synthesis with given pattern directivity is considered. The antenna synthesis problem has ambiguous solution, because the same pattern at the same frequency could get with the different current distribution on certain antenna surface. But there exist unique optimal current distribution in order to get efficiently given pattern. It could be realized with minimal value of: the: currents, reactive near field and the best matched antenna to radiation. Optimal currents distribution is related to the desire pattern's scattered field singularities.
