Abstract

The invention discloses an orthogonal dual-polarized metal slot antenna array structure and an antenna array containing the structure, and solves the problem in the prior art that high-temperature welding formation is adopted to cause poor antenna precision, resulting in reducing the yield, limiting by the welded aluminum alloy material and reducing the mechanical strength of the antenna, or the assembly formation of spare parts is adopted, resulting in increasing the weight of the antenna, reducing the mechanical strength of the antenna and increasing the number of structural parts that are independent of electromagnetic properties, so as to narrow the scope of application. The antenna array structure comprises an antenna bottom plate, and a sub-structure unit mounted on the antenna bottom plate and interposed by horizontal radiating unit pieces and vertical radiating element pieces. The antenna array includes an antenna array structure. The antenna array structure and the antenna array have the advantages of simple structure, scientific and reasonable design and convenient use, and can effectively ensure the accuracy of the antenna to improve the production yield, effectively improve the mechanical structure strength, reduce the weight of the antenna, and ensure the electromagnetic performance of the antenna array to expand the applicable range.

Description

technical field

[0001] The invention belongs to the technical field of antenna structures, and in particular relates to an orthogonal double-polarized metal slot antenna array structure and an antenna array containing the structure. Background technique

[0002] Orthogonal dual-polarized metal slot antenna array has many advantages, such as wide operating frequency band, high gain, high power withstand, and can automatically match targets with different polarization characteristics. In addition, this kind of antenna has a relatively small aperture and good structural strength, which is conducive to the integrated design of the airborne platform, and is widely used in the broadband phased array antenna system of the airborne platform. There are two common structural forms of orthogonal dual-polarization metal slot antenna arrays, one is integrally welded and formed, and the other is assembled and formed from individual parts.

[0003] The structural form of the integrally we...
