To solve the problems of simultaneous viewing of space in a wide sector of angles, multipath antenna devices based on lens antennas with a conformal aperture are used. An example of such lenses are wide-angle Luneberg lenses with a modified profile of a dielectric lens with a rounded edge.

Multipath antennas based on Luneberg lenses are widely used in communication, location and navigation. A significant number of works are devoted to their research, including monographs, textbooks, articles, dissertations. However, there is very little description of the parameters and design in the millimeter wavelength range of this type of wide-angle antennas in the modern literature, and information about an MLA based on a Luneberg lens with such dimensions and frequency range has not been found at all. Therefore, the topic of this article is relevant. The object of research in this work is a model of a multipath antenna based on a Luneberg lens developed with co-authors at the JSC TNIIS enterprise.

The purpose of the work is to describe the design of an MLA based on a Luneberg lens developed at the JSC TNIIS enterprise. As well as a description of the parameters of such an MLA and obtaining experimental radiation patterns at four frequencies. This study was conducted as part of a research work called «Lens» at the JSC TNIIS enterprise related to the need to find ways to improve the accuracy of radio direction finders with Luneberg lenses. The task was to develop a receiving antenna based on an LLB with a wideangle non-mechanical scanning of space in the azimuthal plane with an operating frequency range of 17.5−40 GHz. Since the requirements are imposed on the shape of the bottom only in the azimuthal plane, the antenna is implemented on the basis of a modified cylindrical LLB, the design of which was chosen for reasons of ease of implementation in production, as well as for weight and size and strength characteristics.
