Method of Electrostatic Analogy

Abstract

It is considered the analysis method for electromagnetic fields and directional characteristics of antenna arrays consisting of parallel linear radiators based on the calculation of the electrostatic fields of charges located on parallel wires. It is demonstrated the advantage of using radiators with in-phase current distribution. It is shown that the application of radiators with in-phase current distribution allows to decrease the length of antenna array and to provide the high directivity in a wide frequency range. It is stated the task of optimization of considered arrays by methods of mathematical programming.
