“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 explained method allows for building an efficient algorithm of calculating characteristics of block phased arrays intended for scanning in a limited sector of angles and normal phased arrays with elementwise phasing considering interaction of radiators in the …


The explained method allows for building an efficient algorithm of calculating characteristics of block phased arrays intended for scanning in a limited sector of angles and normal phased arrays with elementwise phasing considering interaction of radiators in the outside space and power wiring circuits.
The given numerical results show the possibility of considering the influence of the attenuator when designing phased antenna arrays.
 


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.
