Electromagnetic analysis of infinite 2D antenna array with random parameters

Abstract

The method of electromagnetic analysis of infinite two-dimensional antenna array with random parameters is proposed. The method uses compensating sources technique and method of generalized scattering matrix which allow one to analyze infinite non-uniform antenna arrays containing defects of the periodical structure in form of array elements with random parameters. The proposed method takes into account influence of random parameter variation relatively its average value in linear approximation. Expressions for the dispersion of the array parameters are obtained in frame of the proposed method.
