Abstract

The invention provides a large-scale MIMO array antenna. The large-scale MIMO array antenna comprises at least one MIMO antenna module and a radome which are adaptive in shape. Each MIMO antenna module comprises a plurality or radiation units, a support frame, a power division network module, a calibration network module and a radio frequency connector, the radiation units are arranged on the power division network module in an array mode and form a subarray unit a mode of at least two radiation unit being one group, the power division network module and the calibration network module are fixed on the support frame, one end of the power division network module is electrically connected with the subarray unit, the other end of the power division network module is electrically connected withone end of the calibration network module, the other end of the calibration network module is electrically connected with the radio frequency connector, and the radio frequency connector is connectedwith a radio frequency TR module. According to the invention, a reflecting plate in the traditional antenna design is eliminated, the structural composition is simplified, and the thickness of the antenna is reduced.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a massive MIMO array antenna. Background technique [0002] With the development of the fifth-generation mobile communication technology (5th-generation, 5G), the application of massive MIMO antennas is gradually becoming popular. At present, the existing 5G antenna is usually built into the radio frequency equipment in the form of an antenna module, and is packaged with the radio frequency equipment as a whole. Since the size and weight of the equipment are directly related to the utilization efficiency of the antenna resources of the macro station tower, the miniaturization and lightweight design of the equipment has the advantages of obvious advantage. In the prior art, MIMO antennas follow the structural design of traditional base station antennas. The main components of the antenna include: radiation unit 110, reflector 100, power division network module 130, calibration n...
