The aim of this thesis is to develop electrodynamic-level mathematical models describing printed-circuit radiators of an irregular shape within an antenna array that make it possible to analyze the radiation pattern characteristics of separate printed-circuit radiators located on finite screens of an irregular shape and mathematical models for analyzing the characteristics of ultrawideband ribbon antenna arrays with wide-angle scanning. Also, the aim of the thesis is to develop software based on the mathematical models and use the developed software to analyze the characteristics of the abovementioned devices.
