Definitions
- the invention relates to an arrangement and a method for influencing and controlling alternating electromagnetic fields and / or antennas and antenna diagrams.
- the fields of application of the invention extend primarily to the areas of communication technology in the fields of stationary, portable and mobile transmission and reception systems of high-frequency electromagnetic radiation sources, in particular of geostationary or rotating satellite systems and land or air mobile sources, contactless sensor technology, security technology and radar technology.
- Known methods for evaluating sources of electromagnetic radiation preferably use source-specific signals as the evaluation criterion or, in the case of the known position or movement property of the source, its known spatial coordinates or movement information or their relationship to other known spatial coordinates.
- the evaluation is carried out on the basis of known position data from the source and / or signal receiver or on the basis of a comparison of the transponder assignment with a reference assignment.
- Such a reception system is tracked on the basis of the evaluation of the reception signal with the inclusion of external sensors and / or data on the movement or direction information of the observer.
- the object of the invention is therefore to provide an arrangement located in the so-called “low-cost range” for the targeted influencing and control of an electromagnetic field, preferably in antenna arrangements or excitation of antenna arrangements, preferably of surface radiators, with the possibility of changing the components of the defined electromagnetic radiation field, so that a limited but arbitrarily changeable synthesis and / or formation of the radiation diagram, preferably the or the

- the arrangement of the radiator elements is in the area of the aperture space, which is enclosed by the two aperture levels, in a solution-specific manner, preferably parallel or three-dimensional to the aperture level.
- the generation of the parasitic source field in the area of the aperture space takes place through a controllable interaction of the radiator elements with the source field of source 1 (passive) or solution-specific by overlaying the source field with a reinforcing effect (active) or feeding the radiators through a relationship that is determined to the source field ( Phase and amplitude) standing excitation (external supply).
- the emitters or pairs of emitters are designed to be task-specific as planar surface emitters, dipole or monopole arrangements, combinations of the aforementioned or so-called aperture emitters.
