This paper is devoted to study of approaches to radiation pattern side lobe level reduction for a circular antenna array. These researches are executed for a circular antenna array of a fixed radius. The radiation pattern beam width of a circular antenna array is kept constant. Due to the developed algorithm, it is possible to define a relationship between ring radius and circular array antenna parameters.
