Abstract :
The general approach to solving the non-linear problems of antenna arrays (AA) synthesis under the prescribed requirements on the amplitude or power directivity pattern (DP) is considered. The approach is based on the use of mathematical models of AA, which take into account the mutual coupling of radiators. The examples of synthesis of microstrip antenna arrays, and antenna arrays consisting of linear vibrators, spiral radiators, waveguide radiators are given.
