Problems solved by technology

However, due to the characteristics of the metasurface antenna unit, the traditional metasurface antenna cannot meet the requirements of dual polarization and wide bandwidth at the same time, and its application range is limited.
[0003] The phase shift curve of the existing metasurface antenna unit has poor linearity, so the working bandwidth of the metasurface antenna array is relatively narrow
In addition, the existing metasurface antenna unit works in a dual-polarization state, and the cross-polarization component of the unit is relatively large, which is not convenient for independent regulation of electromagnetic waves with different polarizations at the same time.

The antenna unit provided by the invention and the antenna array formed by the unit provided by the invention can have good polarization characteristics, wide operation bandwidth and good phase shift characteristics.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna unit and an antenna array. Background technique [0002] Metasurface antennas are widely used in electromagnetic communication, radar and other fields. With the continuous development and improvement of electronic wireless communication technology, both radar and communication systems expect antennas to have more functionality and adaptability. However, due to the characteristics of the metasurface antenna unit, the traditional metasurface antenna cannot meet the requirements of dual polarization and wide bandwidth at the same time, and its application range is limited. [0003] The linearity of the phase shift curve of the existing metasurface antenna unit is poor, so the working bandwidth of the metasurface antenna array is relatively narrow. In addition, the cross-polarization components of the existing metasurface antenna units working in the...
