“Influence of boundary effects on characteristics of wideband antenna array” In the work [1] based on the model of an infinite antenna array, a flat antenna array consisting of compact radiators with impedance structure of large inductive … |
Based on the solution of the boundary value problem for an infinite antenna array, a mathematical model of a finite flat antenna array in an infinite screen with impedance structure is built. Results of calculations are given by the example of radiant …
In the work [1] based on the model of an infinite antenna array, a flat antenna array consisting of compact radiators with impedance structure of large inductive magnitude is considered. However, usage in antenna arrays of radiators of small electric sizes with accordingly small distances between them (strong interdependence) requires the following question to be answered: which geometrical size of the radiating row of a real antenna array must have for decreasing of interdependence between the radiators will not significantly decrease their performance.

In section of “Publications-Dissertations” the “Metal-dielectric structures in antenna arrays, radio-absorbing coatings and near-omnidirectional radiators” dissertation is published.
Author: I. V. Sutyagin.
The aim of the dissertation 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.
