Abstract

The invention relates to a dense array antenna of a double-layer structure. The antenna comprises an antenna cover (1), a PCB radiation element (2), a reflecting plate (3), a coupling calibration network PCB (4), a blind connecting plug PCB (5), a bottom sealing plate (6) and an N-type calibration joint (7). A bottom layer is a blind connecting plug layer and an upper layer is a coupling calibration network layer. The coupling calibration network PCB (4) is welded and connected to the blind connecting plug PCB (5) through a cable so as to form a complete feed network of the double-layer structure, and then an antenna possessing a 3D wave beam forming capability is formed. Multi-direction wave beam forming can be realized, a wireless communication system capacity is greatly increased and optimal system performance is achieved. An operator is helped to maximumly use an existing site location and frequency spectrum resources and excellent performance of mobile communication is guaranteed.

Description

technical field [0001] The invention relates to a device used in the field of mobile communication, in particular to a dense array antenna with a double-layer structure. Background technique [0002] With the continuous development of my country's mobile communication industry, research on the fifth generation mobile communication system (5G) has begun. The 5G mobile communication system requires greater communication capacity and higher wireless spectrum efficiency. The base station antenna needs to support 3D beamforming and more powerful MIMO functions. [0003] For improving mobile communication capacity, the conventional method is to use multi-port antennas of base stations with polarization diversity technology, which can reduce multipath fading and improve link stability, and use multi-port MIMO technology to further increase mobile communication capacity. However, in the 5G communication era, technical requirements such as large data traffic, high speed, and low lat...
