However, considering the practical application scenario and application environment of the system and the antenna array, when the 5G base station with the Massive MIMO antenna array is built, the volume of the antenna array cannot be very large due to the practical space limitation. Under the condition that the physical size of the antenna array is limited, mutual coupling and interference among a plurality of antenna units can inevitably cause the degradation of the antenna performance, and the antenna array is mainly characterized in the following aspects:
(1) The antenna side lobe is higher, and the beam scanning capability of the array is greatly influenced;
(2) The signal-to-noise ratio is poor due to mutual interference among the antenna units, so that the data throughput rate is directly affected;
(3) The energy capable of being effectively radiated is reduced, so that the gain of the antenna array is reduced, and the energy utilization efficiency is low.
In summary, in the low frequency band and the high frequency band applicable to 5G, there is an urgent need to find a theory and a design method for effectively improving the performance of the spatial limited Massive MIMO antenna array, so that the size of the antenna array can be reduced, and the performance of the original antenna array can be maintained.
