Аннотация: This study is devoted to the development and research of multibeam antennas based on anisotropic metasurfaces with one or several feed points. An innovative technique for synthesizing the tensor impedance distribution for the formation of three beams from a radiating metasurface was proposed. Prototypes of the proposed antennas in the Ku-band frequency with one and three feed points were fabricated, and their characteristics were experimentally investigated. The gain of the manufactured multibeam antennas reaches 23 dBi. Good agreement between the results of the numerical simulation and experimental data was achieved, which indicates the reproducibility of the synthesis method in practice. Multibeam antennas on anisotropic metasurfaces can be scaled to high frequencies and effectively used at operating frequencies up to the sub-terahertz range. Such antennas are promising for the development of terrestrial communication infrastructure as 5/6G transmitters and repeaters, as well as for use as a payload of low-orbit satellite systems.

Аннотация: In this paper, we propose a novel method for synthesizing a multibeam metasurface antenna (MSA) for use in a space application - a payload component of a small satellite as part of a low Earth orbit (LEO) satellite communication constellation. MSA is synthesized using the holographic technique with a divergent phase distribution. Using this method, a low-cost multi-beam Ku-band antenna with seven flattened beams is developed. The results of the numerical simulation and experimental study of the proposed seven-beam MSA were presented. The gain of each beam is about 25 dBi, the aperture efficiency of the MSA is ∼40%. Each individual beam had a separate feed point and its own inclination angle (0°, ±3.5°, ±7°, ±10.5°). This paper shows that the presented MSA is not inferior in its characteristics to similar solutions, but is more compact and lighter, and also allows the formation of complex radiation patterns.
