Embodiment 1

[0040] Figure 1~Figure 3 A specific structure of the millimeter wave antenna array of the present invention is shown. Such as figure 1 As shown, the millimeter-wave antenna array is an 8×8 antenna array, which is composed of 64 identical antenna elements, and its overall structure is honeycomb.

[0041] The structure of a single antenna element is as follows figure 2 , image 3 As shown, it includes a metal support, and a metal cavity with an open top is formed in the middle of the metal support, which is used to accommodate the dual-polarization cavity filter. On the one hand, the metal support can The filter plays the role of support and fixation. On the one hand, it can assist the accurate positioning of each array element in the antenna array, and on the other hand, it can also provide a reflection surface for the radiation component integrated at the top of the dual-polarization cavity filter.

[0042] The dual-polarization cavity filter in this embodiment adopts a ...

Embodiment 2

[0045] Figure 5~Figure 7 Another specific structure of the millimeter wave antenna array of the present invention is shown. Such as Figure 5 As shown, the millimeter-wave antenna array is also an 8×8 antenna array, which is composed of 64 identical antenna elements, and its overall structure is honeycomb.

Abstract

The invention discloses an antenna array element of a vertically integrated filter. The antenna array element includes a dual polarized cavity filter and a dual polarized radiating element integratedon top of the dual polarized cavity filter; the dual polarized cavity filter is composed of a plurality of dual polarized resonance cavities which are connected in order from bottom to top, and a coupling window is arranged between the adjacent dual polarized resonance cavities. The invention also discloses a millimeter wave antenna array and a millimeter wave communication device. The element integrates the radiating element and the filter in a vertical direction, has the advantages of compact structure and small space occupation, and more importantly, ensures that the phases and amplitudes of signals transmitted by each array element in the antenna array are substantially the same.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to an antenna array element of a vertically integrated filter. Background technique [0002] 5G millimeter wave frequency band communication is the most cutting-edge communication technology and the most important research direction in the field of communication in the near future. All major communication companies in the world have carried out related research work. At present, the 5G millimeter wave communication systems of various companies use MIMO and phased array technology, most of which use array antennas with 8*8 or 16*16 radiation elements, including waveguide slot array antenna arrays and patch arrays. antenna array etc. Some schemes adopt two-dimensional scanning schemes, and some adopt one-dimensional scanning schemes. [0003] No matter which form is used, the local oscillator radiation must be suppressed to meet the international radio radiation sta...
