“Numerical analysis of level of uncoupling between transmitting and …” In case of different destination antenna saturation modern radio systems the array antenna (AA) bypassing, located in bounded capacity, in angle region near ±600 … |
The principles of constructing antenna arrays (AA) and beam formers (BF) for broadband isolation increase between AA are formulated. The values of isolation levels for cosine and exponential amplitude distributions at the BFD outputs …
In case of different destination antenna saturation modern radio systems the array antenna (AA) bypassing, located in bounded capacity, in angle region near ±600 of principal plane and frequency band with contact ratio no less than 2, increase means much. At that essential bypassing magnitude between receiving AA outcome and transmitting AA input can reach -100…-130 dB.

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.
