Influence of amplitude distribution within a module and over a system of modules on the pattern of multimodule antenna array

Abstract

Numerical simulation results for multimodule antenna array in form of linear array consisting of rectangular subarrays (modules) are given. It's shown that grating lobes appear in the array factor if the amplitude distribution within a module and within a system of modules are independent from each other. The dependence of grating lobes level on amplitude distribution parameters is considered.
