“GuidesArray Coaxial”

With this program you can execute mathematical modelling by the phased periodic plane antennas array from coaxial wave guides in sector of angles and a band …

 



GuidesArray Coaxial is supposed for purposes of modeling of phased antenna arrays created using coaxial waveguides. Such antenna arrays can be used as power transmit \ receive antenna systems in various areas of radio-engineering.


With this program you can execute mathematical modelling by the phased periodic plane antennas array from coaxial wave guides in sector of angles and a band of frequencies.
The offered mathematical model is founded on an electrodynamic solution of a boundary task in a unit mesh of infinite structure.

“Research of impedance properties of receiving array of rectangular waveguides”

In the article [1] two requirements for radiant strips (RS) of a wideband wide-angle antenna array (AA) are formulated: they must have small …

 



Presents frequency dependencies of surface impedance near an array of rectangular waveguides when incident to flat electromagnetic wave, computed on a PC are shown. When placing radiant strips over an optimized waveguide array, contact ratio in frequency up to 2 and more …


In the article [1] two requirements for radiant strips (RS) of a wideband wide-angle antenna array (AA) are formulated: they must have small electric sizes and be located in a plane, wave impedance Z of which satisfies the condition , where W=120π — wave impedance of the free space, in the entire working area.
 



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.
