Analysis of the accuracy of EM simulations of antenna arrays and arrays in vicinity of complex structures, where array elements are modeled by using far field sources, is presented in this paper. Antenna arrays with strong mutual coupling between the elements are the main problem under consideration. It is shown that if the antenna elements are minimum scattering antennas fed by current generators,...
We performed a comparison between the radiation pattern of a simulated antenna and its actual field measurement in the presence of a radome. The simulated main beam properties fit identically within the accuracy of the measurements. The side lobes levels are determined in the region of ±30° to within the accuracy of <3dB in intensity.
