The embodiment of the invention discloses a mirror 3D MIMO half-wave antenna array and an array establishment method. The mirror 3D MIMO half-wave antenna array comprises a 2D MIMO half-wave antenna array and a reflecting mirror, wherein the 2D MIMO half-wave antenna array is arranged at the mirror surface side of the reflecting mirror; and a virtual image of the 2D MIMO half-wave antenna array inthe reflecting mirror and the 2D MIMO half-wave antenna array form a mirror 3D MIMO half-wave antenna array. According to the embodiment of the invention, the reflecting mirror is additionally arranged on the basis of the 2D MIMO half-wave antenna array through adopting a mirror technology, so that the 2D MIMO half-wave antenna array is enabled to generate a virtual image behind the mirror surface of the reflecting mirror, the mirror 3D MIMO half-wave antenna array is formed, the cost, technology, volume and weight of the mirror 3D MIMO half-wave antenna array are almost the same as those ofthe 2D MIMO half-wave antenna array, but the beam forming of the mirror 3D MIMO half-wave antenna array is much better than that of the 2D MIMO half-wave antenna array.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a mirrored 3D MIMO half-wave antenna array and a method for establishing the array. Background technique [0002] The traditional 2D MIMO half-wave antenna array technology is mature, but the sidelobe of the shaped beam generated by the antenna is as large as the main lobe in the propagation direction, which not only loses radiated energy, but also may cause interference. The existing 3D MIMO half-wave antenna arrays have good beamforming and directivity effects. Even for a 3D MIMO half-wave antenna array with only two elements in the transmission direction, its beamforming also has three distances between adjacent elements. Parameters such as phase difference and three phase differences can be adjusted by the system. In terms of beamforming and other functional processing, it still has excellent adjustability. However, because three-dimensional...
