Abstract
Previously, we established that the total scattering field of the receiving antenna includes the information component of the total scattering field and the orthogonal component. Each of these components consists of a main and an additional component. Moreover, only the main information component of the total scattering field participates in the transfer of energy from a plane wave to the antenna load, despite the fact that both components of the total scattering field component have the same amplitude and phase characteristics and they differ from each other only in amplitudes. This work is devoted to the study of the connection between the components of the total scattering field component and the information component of the total scattering field of the receiving antenna with its load. It is shown that the currents that are created in the antenna load by the additional component of the total scattering field and the orthogonal component of the total scattering field cancel each other out, and the resulting current in the receiving antenna load is determined only by the main component of the total scattering field. This explains that, despite the identical amplitude and phase characteristics of the main and additional components of the total scattering field, only the main component is involved in the transmission of information from the plane wave to the antenna load.
