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.

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 … News archive |
It is shown that when the antenna radius is increased, directive gain of spherical antenna with optimal excitation asymptotically approaches directive gain of the equivalent flat cophasal aperture with uniform amplitude–phase distribution of collinear currents. The …
There is known [1] an approximate method for calculating DD and CDD of convex beam diffractional antennas, based on representing radiation field as a superposition of magnetic current fields and induced electrical currents on the ideally conducting surface of the antenna in given amplitude−phase distribution of the exciting magnetic current. Electric currents are determined in short−wave approximation. Amplitude−phase distributions of the exciting magnetic current, providing maximum value of CDD of non−superdirective antenna are examined in works [1…3] in approximations of physical optics.
