Direct study of fields and radiation patterns of antennas with the account of closely located objects

Abstract

Gain-phase distributions of an electromagnetic field and the radiation patterns horn antenna for planar tasks, horn antenna in a combination to the various close located objects are submitted. The problem was solved in time area, then by means of Fourier transformation was translated in frequency. The task solution in time area allows to analyze objects with the sizes 500x500 wave-length with step of digitization of 1/20 wave-length (100 million units of a grid) on the personal computer with operative memory 2Gb. The example of the analysis of distortions of the radiation patterns by the phased array obstacles and objects is given.
