Description

A super-large-scale MIMO multi-beam lens antenna system Technical Field

[0001] The present application relates to the field of lens antenna technology, and in particular to an ultra-large-scale MIMO multi-beam lens antenna system. Background Art

[0002] With the rapid development of wireless communication technologies such as 5G and 6G, the scale of MIMO systems is constantly expanding, and large-scale MIMO systems based on lens antenna arrays have gradually become a research hotspot. Large-scale MIMO systems based on lens antenna arrays have obvious advantages in improving spectrum utilization, increasing system capacity, and improving signals, and have important theoretical significance and application value.

[0003] In existing technologies, the antenna pattern of a planar phased array antenna will be severely deformed after scanning at 45 degrees, and its gain will also drop rapidly, resulting in the MIMO system being unable to simultaneously meet the requirements of horizontal and vertical beam scanning. Active antennas often compensate for gain loss by adjusting amplitude and phase through large-scale calculations to achieve horizontal and vertical scanning and coverage, resulting in a large amount of computing resources and energy consumption. In addition, some manufacturers also use multiple antennas to form an antenna array in a cylindrical or circular arrangement, so that different antennas are responsible for scanning beams at different angles, thereby achieving horizontal and vertical scanning and coverage. This leads to a significant increase in the number of antennas required in the antenna array, resulting in excessively high construction costs for the MIMO system.
