“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 #12


Based on the solution of the boundary value problem for an infinite antenna array, a mathematical model of a finite flat antenna array in an infinite screen with impedance structure is built. Results of calculations are given by the example of radiant …


In the work [1] based on the model of an infinite antenna array, a flat antenna array consisting of compact radiators with impedance structure of large inductive magnitude is considered. However, usage in antenna arrays of radiators of small electric sizes with accordingly small distances between them (strong interdependence) requires the following question to be answered: which geometrical size of the radiating row of a real antenna array must have for decreasing of interdependence between the radiators will not significantly decrease their performance.
