Currently, the active development of the telecommunication facilities, used by an increasing number of transmitting and receiving devices can be observed. Between nearby objects in space (antennas, metal-dielectric structures) occurs electrodynamic interactions that affect their work. This paper aims to develop methods for the assessment of the characteristics of this interaction. A leading approach to the study of this problem is the use of a method based on generalized scattering matrix. Knowledge of the generalized scattering matrix provides the possibility for calculations of the characteristics of the antenna system, without considering the geometry. By analogy with the use of matrices of two-and multiprobe used in electrical circuits, generalized scattering matrix is carried out to minimize the calculations for the analysis of complex antenna systems. The paper presents the results of modeling of the interaction loop antenna ball, which is formed of a dielectric material. The dispersion characteristics were calculated based on the method of integral equations. On the basis of calculations of the electrodynamic interaction between objects is possible to estimate the influence of the position of the antennas on the level of measured electromagnetic fields. The materials of the article are of practical value to professionals associated with the design of wireless networks indoors.
