Abstract

The present disclosure provides a MIMO array antenna beam optimization device based on antenna dummy, including: MIMO array antenna, including: several radiation antenna units, the several radiation antenna units are used for radiation or reception of electromagnetic signals; An antenna dummy element is used to suppress the mutual coupling strength between adjacent radiating antenna elements; a plurality of second antenna dummy elements is used to suppress the surface wave of each radiating antenna element. The present disclosure also provides a MIMO array antenna beam optimization method based on antenna dummy.

Description

technical field [0001] The present disclosure relates to the technical field of antennas, and in particular to an antenna dummy-based MIMO array antenna beam optimization device and method. Background technique [0002] MIMO array antennas have been widely used in target detection, data transmission and communication fields due to the characteristics of large number of channels, large spatial freedom, and large channel capacity. With the development of light and small platforms, high-density integrated and miniaturized MIMO array antennas have become an important direction of development. High-density integrated MIMO array antennas often integrate antennas and radio frequency channels to greatly reduce size, volume, etc. , but the high integration level leads to serious coupling between MIMO antenna units and sub-arrays, the beam distortion of the pattern, the further deterioration of the antenna pattern distortion caused by active devices, and the narrowing of the bandwidth...
