“GuidesArray Circular”

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

 



GuidesArray Circular is supposed for purposes of modeling of phased antenna arrays created using circular 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 circular 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.

The results of estimating the characteristics of coaxial emitters in flat phased arrays.


Rectangular and circular waveguides are used as emitters in phased arrays [1]. We are interested in arrays made with open endings of coaxial waveguides excited by a mode . Such waveguides have a fairly high operating power while their cross-section sizes are much less than that of the above-mentioned types, which enables the realization of scanning through the wide range of angles without filling waveguides with dielectric…
 



In section of “Publications-Archive” the “Admittances of antenna array waveguide radiators on a wedge: the results of numerical and experimental studies” archival article is published. Author: E. M. Privalov.


In the article the quantitative analysis of physical processes that occur during the excitation of planar and rectangular waveguides with an infinite flange, with a bending flange and an array of planar and rectangular waveguide radiators on an infinite plane and on an infinite wedge has been carried out.
