“GuidesArray Rectangular”

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.

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…
 


News #119


In section of “Publications-Archive” the “The Algorithm and Results of Calculating the Radiation Patterns of Antenna Arrays on an Infinite Wedge” archival article is published. Authors: Z. K. Kudrya, E. M. Privalov.


In the article Green's tensor function has been used as a basis to get the expression for the radiation pattern of a rectangular waveguide radiator array located on an infinite perfectly conducting wedge. The obtained expression has been analyze, which has made it possible to calculate the integral in a complex plane with the help of the saddle-point method.
