In case of different destination antenna saturation modern radio systems the array antenna (AA) bypassing, located in bounded capacity, in angle region near ±600

 



The principles of constructing antenna arrays (AA) and beam formers (BF) for broadband isolation increase between AA are formulated. The values of isolation levels for cosine and exponential amplitude distributions at the BFD outputs …


In case of different destination antenna saturation modern radio systems the array antenna (AA) bypassing, located in bounded capacity, in angle region near ±600 of principal plane and frequency band with contact ratio no less than 2, increase means much. At that essential bypassing magnitude between receiving AA outcome and transmitting AA input can reach -100…-130 dB.
 



In section of “Publications-Archive” the “Solution to the electromagnetic wave diffraction problem using the method of continued boundary conditions” archival article is published. Authors: A. G. Kyurkchan, N. I. Smirnova.


In the article the method of the continued boundary conditions (MCBC) is generalized on three–dimensional vector problems of waves diffraction on bodies of revolution.
