“Characteristics of radiation of continuously excited spherical antenna”

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 …

 



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.
 



In section of “Publications-Archive” the “The Algorithm and Results of Calculating the Characteristics of Waveguide Radiator Arrays” archival article is published. Authors: E. M. Privalov, Z. K. Kudrya, S. D. Gorina.


In the article the method and algorithm of calculating the input characteristics for the radiators of antenna arrays with a small number of radiators have been developed.
