Abstract
Cosine sum amplitude distribution of different degrees for discrete emitting systems which has an optimal ratio of the side lobes level and antenna aperture efficiency has been synthesized and analyzed. It is obtained by the superposition of the -degree cosine amplitude distribution and the - degree cosine amplitude distribution having antiphase side lobes. The synthesized amplitude distribution for the parameter  is similar to the “squared cosine on a pedestal” distribution, but by setting the,  parameters it is possible to optimize the amplitudes of extreme emitters of antenna arrays by the side lobes minimum criterion. The method of amplitude distribution synthesis and correction is proposed. The correction of amplitude distributions is realized by means of corrective radiation patterns with known amplitude distributions. That allows bringing the synthesized radiation pattern nearer to the optimal shape in the area of the side lobes envelope and obtaining high antenna aperture efficiency for the prescribed side lobes level and radiation patterns of emitters. The radiation pattern of antenna arrays for the synthesized amplitude distribution has an increasing level of side lobes. The radiation pattern has a uniform envelope line for side lobes with regard to directional properties of emitters. Thus the antenna aperture efficiency for such amplitude distributions is higher than the antenna aperture efficiency for Dolph-Chebishev distributions. The amplitude distributions obtained can be used as the basis for the synthesis of radiation patterns with an increasing level of the side lobes.
Keywords: Antenna array, amplitude distribution, side lobes level, antenna aperture efficiency, corrective radiation pattern, rising level of side lobes
