Highly-integrated MIMO antenna

Abstract

The invention relates to the technical field of communication, and discloses a highly-integrated MIMO antenna. The antenna comprises a dense radiation array assembly and a coupling calibration plate assembly. The dense radiation array assembly comprises a radiation array substrate, and a radiation unit, a decoupling unit and a power division circuit which are integrated on the radiation array substrate. The coupling calibration plate assembly comprises a calibration plate substrate, a calibration circuit and a radio frequency input circuit, wherein the calibration circuit and the radio frequency input circuit are arranged on the calibration plate substrate; the radiation array substrate is detachably connected with the calibration plate substrate; an input port of the power division circuit is connected with the radio frequency input circuit through a feed conductor; and the radio frequency input circuit is connected with a radio frequency connector. The highly-integrated MIMO antennaprovided by the invention is light in weight, simple in structure, high in integration level, few in parts, simple and convenient to install, and free of the adverse impact of low labor hour efficiency and poor index consistency and the like caused by multi-part assembly; and the antenna is low in antenna cost, good in index consistency, simple to assemble, high in production efficiency and suitable for mass production.
