Abstract

The invention provides a Massive MIMO array antenna and a base station, the Massive MIMO array antenna comprises a plurality of oscillators, a plurality of feed sheets, a plurality of feed lines and a second substrate, each feed sheet comprises a first quadrant region, a second quadrant region, a third quadrant region and a fourth quadrant region, the first quadrant region and the second quadrant region are in the same phase, the third quadrant area and the fourth quadrant area are in the same phase, the first quadrant area is at least provided with a first feeding point and a second feeding point, the second quadrant area is at least provided with a third feeding point and a fourth feeding point, and the plurality of feed lines at least comprise a first branch and a second branch. The first branch is electrically connected with the first feeding point and the second feeding point, and the second branch is electrically connected with the third feeding point and the fourth feeding point. According to the Massive MIMO array antenna and the base station provided by the invention, the mutual coupling between adjacent arrays can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a Massive MIMO array antenna and a base station. Background technique [0002] Massive MIMO technology plays a vital role in 5G applications. The MassiveMIMO array antenna uses multiple transmitting antennas and multiple receiving antennas at the transmitting end and the receiving end respectively, so that the signal is transmitted and received through multiple antennas at the transmitting end and the receiving end, which can double the channel capacity of the system and is regarded as 5G The core technology of mobile communication. [0003] At present, the number of units of the Massive MIMO array antenna is large, resulting in a large overall volume of the Massive MIMO array antenna. In order to reduce the size of the Massive MIMO array antenna, the spacing between adjacent unit sub-arrays is getting smaller and smaller, resulting in stronger coupling between unit sub-...
