When using an accelerating metal-lamellar cylindrical lens to increase the signal level towards the remote subscriber of the wireless access system, a shadowing effect can be exerted on users outside the main lobe of the radiation pattern of this lens. The report presents the results of an experimental study of the field structure in the azimuth directions, different from the axis of the lens, oriented to the priority subscriber. The characteristics of the developed and manufactured software-hardware model, including metal-lamellar lens; a device for generating a data packet and emitting a signal; set of receiving sensors; the necessary software for the collection and processing of results. The measurements carried out under typical conditions showed that the “shading” sector estimated by (signal + noise) / noise ratio for the lens starts at about 6° with respect to the lens axis and ends at 30°.References
