Abstract The article discusses methods for calculating the electromagnetic characteristics of reflector antennas based on the finite integration method, the method of moments, and the hybrid method. In the course of the study, a performance comparison of these methods in the process of calculating the reflector antenna characteristics was made. Comparison of the calculation efficiency was carried out using four computing devices. On the basis of the calculations, the graphs of the scattering matrix and the directional diagrams of the antenna under study were obtained

Least Squares Minimization

A method to optimize the radiation pattern of rotationally symmetric reflector antennas with an array feed is introduced. The optimization of the radiation pattern for the purpose of beam scanning is achieved by adjusting the excitation condition of each element of the planar array. The radiation-pattern calculation is based on the physical optics radiation integral. The excitation conditions (amplitude and phase) of the array elements are calculated using the least-squares minimization method.
