[0039] Example 1: 24-element broadband multi-layer flat dual-polarized antenna array

[0040] For the upper dielectric material board, choose a 5880LZ dielectric board with a length of 26.78mm, a width of 26.78mm, a thickness of 3mm, and a dielectric constant of 1.96.

[0041] Medium dielectric material plate, choose Rogers RT dielectric plate with a length of 26.78mm, a width of 26.78mm, a thickness of 0.125mm, and a dielectric constant of 2.2.

[0042] For the lower dielectric material board, choose a 5880LZ dielectric board with a length of 26.78mm, a width of 26.78mm, a thickness of 3mm, and a dielectric constant of 1.96.

[0043] The horizontal radiation units form a 3×4 array and are uniformly printed on the upper surface of the middle dielectric material board 2 , and the vertical radiation units form a 4×3 array and are uniformly printed on the lower surface of the middle dielectric material board 2 . The cell pitch is 8mm.

Abstract

The invention provides a broadband multi-layer flat-plate dual polarized antenna array, comprising horizontal radiation units arranged in the form of an n*m array, vertical radiation units arranged inthe form of an m*n array, a plurality of balanced feed structures, an upper dielectric material, a middle dielectric material plate, a lower dielectric material plate, a metal bottom plate and a feeddevice, wherein n and m are integers. The antenna array achieves a broadband effect by adopting the technical measures of using the radiation units with step structures for enhancing the coupling effect and the balanced feed structures, loading dielectric layers above the radiation units and the like. At the same time, since the horizontal radiation units and the vertical radiation units are spatially perpendicular to each other, dual polarization performance is formed.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a broadband multi-layer flat dual-polarization antenna array. Background technique [0002] Most of the existing antenna arrays have relatively narrow bandwidths. When the antennas are required to work in multiple frequency bands, multiple antennas are required to implement them, which takes up a lot of space. Some existing broadband antenna arrays have a high section and are difficult to achieve planarization; when dual polarization performance is required, it is often necessary to set multiple sets of mutually perpendicular units in space, which increases the volume of the antenna. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of narrow bandwidth, high profile and difficulty in realizing planarization and dual polarization of existing antenna arrays, and provide a broadband multi-layer flat dual polarization a...
