“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.

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


Article #11


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.
 


News #110
