Abstract

The invention provides an MIMO array antenna beam optimization device based on antenna dummy elements. The device comprises: an MIMO array antenna, which comprises a plurality of radiation antenna units that are used for the radiation or reception of electromagnetic signals; a plurality of first antenna dummy elements which are used for suppressing the mutual coupling strength between the adjacent radiation antenna units; and a plurality of second antenna dummy elements which are used for suppressing the surface wave of each radiation antenna unit. The invention further provides an MIMO array antenna beam optimization method based on the antenna dummy elements.

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...
