“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 …
 


Program #2


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.

Article #15


A variant of constructing an ultrawideband wide-angle antenna array based on a multilayer ribbon structure is suggested; the mathematical model of this antenna system is described and the results of numeric modeling are presented.


Speaking about the effectiveness of various ways to provide ultrawidebandness and wide angleness of a receiving antenna system (AS), we should note that in an antenna array (AA) it is usually rather difficult to combine these two properties.
The aim of this work is to suggest a variant of constructing of a receiving AA providing a wide band of operating frequencies and wide sector of operating angles simultaneously. Then, develop a mathematical model of the suggested AA. Based on the constructed mathematical model, conduct a series of numeric experiments to discover the main properties of the AA.
 


News #122


In section of “Publications-Archive” the “Using the alternative representations of a Green's function in the constraint equations for an array of waveguide radiators located on the facet of an infinite wedge” archival article is published. Author: E. M. Privalov.


In the article the Green's function for an infinite wedge has been examined in order to use it to solve the practical technical problems of antenna arrays.
