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


Program #1


GuidesArray Rectangular is supposed for purposes of modeling of phased antenna arrays created using rectangular waveguides. Such antenna arrays can be used as transmit \ receive antenna systems for radio- and television-broadcast centers, cellular and paging …


With this program you can execute mathematical modelling by the phased periodic plane antennas array from rectangular 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.

Article #19


A numerical method for determining the characteristics of plane and circular cylindrical finite antenna arrays that is based on a model of a regular radiating structure and the method of successive reflections is studied. The calculation of the radiation pattern …


When internal and external problems of electrodynamics are solved, the successive reflections (successive diffractions) method is used [1, 2] that ensures enough efficiency for the numerical algorithms of determining the electrodynamic characteristics of complex objects. If modified, the specified method can be used to define the characteristics of finite antenna arrays taking into account edge effects and the interaction of the radiators.
 


News #123


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.
