 “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.

## Article #9

The results of the research of characteristics of a finite slot phased array are given. It is shown that boundary waves cause significant change of a side radiation in large arrays when the beam deviation in a single scan sector is at maximum. …

One of the most efficient methods of numeric research of characteristics of finite antenna arrays is the method suggested in [1]. This method is based on the transformation of the mutual resistance matrix into a circulant matrix and iterative procedure of solution of the system of linear algebraic equations with the transformed matrix. Also efficient is another method based on the concept of boundary waves [2], which states that the distribution of current in a finite antenna array with uniform amplitude and phase distribution of waves propagating in the feeder lines, can be represented as a sum of the regular part and the boundary wave propagating from the border of the radiating matter deep into the array...
