Background. In the automated design of antennas for various purposes, one of the main tasks to be solved is to control of parameters of the radiation patterns of these antennas in the process of optimizing them to meet requirements of the technical specification. These parameters usually include the width of the main lobe of the amplitude radiation pattern at half or zero level power, as well as the maximum level of the side lobes of the radiation pattern of the antenna. Materials and methods. An approach to determining the parameters of the amplitude radiation pattern of an antenna in its automated design is proposed, based on the use of a numerical method for searching for the maximum or minimum of functions of real variables describing this radiation pattern. The possibilities of software implementation of the obtained solutions in the MATLAB system are shown. Results and conclusions. The results of a model study of the possibilities of determining the width of the main lobe of the amplitude radiation pattern at a given level using the numerical method of Newton tangents are presented. An estimate of the error in determining the width of the radiationpattern calculated use this method is given. The prospects of using the Newton tangent method, as well as matrix representations and matrix analysis methods to control of the width of the main lobe of the amplitude radiation pattern and the level of its side lobes in the automated design of acutely directional microwave antennas are shown.
