Abstract

The invention discloses a wide-angle scanning phased-array antenna and communication equipment. The wide-angle scanning phased-array antenna comprises N antenna sub-arrays, wherein each antenna sub-array comprises at least one left-hand polarized first antenna unit and at least one right-hand polarized second antenna unit which are arranged in a rectangular grid shape, and the first antenna unit and the second antenna unit are arranged adjacently. According to the invention, by adjusting the polarization characteristics and the layout positions of the antenna units, the polarization modes of the adjacent antenna units are different, so that the low-gain fluctuation characteristic of wide-angle scanning is realized.

Description

technical field

[0001] The invention relates to the technical field of phased array antennas, in particular to a wide-angle scanning phased array antenna and communication equipment. Background technique

[0002] Phased array antennas have the advantages of realizing multi-beam, controllable sidelobe level, and beam agility, and can realize the adjustment of communication capacity between beams, etc., and have been widely used in wireless systems. After decades of development, phased array antenna technology has made progress in many aspects, such as broadband scanning, wide-angle scanning, and polarization switching. However, it also faces some practical problems, such as the problem of large gain drop in the case of large-angle scanning. At present, there are some technologies to improve the problem of large fluctuations in large-angle scanning gain, such as the use of small spacing, wide beam units, and reconfigurable methods. The mutual coupling is serious, and it is e...
