摘要： This application relates to the field of wireless communication technologies, and discloses an antenna subarray, an antenna array, and a polarization reconfiguration method and apparatus, to provide a polarization reconfigurable antenna and a manner for performing polarization reconfiguration on an antenna. The antenna subarray includes m antenna elements. m is an integer greater than or equal to 2. The m antenna elements are placed at an interval of 360/m degrees in sequence. A distance between any two adjacent antenna elements is less than 0.5 times an operating wavelength. The distance between any two antenna elements is controlled within 0.5λ, so that polarization reconfiguration may be implemented. In addition, compared with a conventional array antenna, a polarization reconfigurable antenna including such an antenna subarray has a small antenna diameter and a small spacing, and may avoid generation of a grating lobe during large-angle scanning.

摘要： Embodiments of the present invention provide an antenna and a communications device. The antenna of the present invention includes a plurality of antenna units (101). Each antenna unit (101) includes a plurality of antenna branches (102) and one feed branch (103). Different antenna branches (102) in a same antenna unit (101) correspond to different frequency bands. At least one antenna unit pair exists in the plurality of antenna units (101). A distance between two antenna units (101) in each antenna unit pair is less than a first preset distance. Radiation directions of antenna branches (102) in each antenna unit pair that correspond to a same frequency band are different. By means of the present invention, isolation between the antenna units in the antenna can be increased.

摘要： This application relates to the field of communications technologies, and in particular, to an antenna module, a MIMO antenna, and a terminal. The antenna module can operate in a plurality of bands, and miniaturization of the antenna module can be implemented. When the antenna module is applied to the MIMO antenna, a size of the MIMO antenna can be reduced. When the MIMO antenna is applied to the terminal, a design requirement for miniaturization of the terminal can be met. An embodiment of this application provides an antenna module. The antenna module includes a clearance area, a support, and at least two branches; each branch is disposed on the support; a partial projection of the support on a horizontal plane falls within the clearance area; and a projection, on the horizontal plane, of one end that is of each branch and that is configured to connect to a feed point is outside the clearance area, and a projection of a tail end on the horizontal plane is inside the clearance area.
