Abstract: The embodiments of the present disclosure provide an antenna vibrator and an antenna, and the antenna vibrator includes a radiation board. The radiation board is a polygon, a part of the radiation board bends downward to form a plurality of support portions and a plurality of hollowed holes, and a plurality of corners of the radiation board bend downward to form a plurality of bending angle portions. The support portion serves to support and connect. At the same time, by forming the bending angle portion on the radiation board, isolation of the vibrator is optimized, and after the vibrator is arrayed, a cross-polarization ratio meets a conventional indicator in a case of not adding a boundary condition.

Abstract: The embodiments of the present disclosure provide an antenna vibrator and an antenna, and the antenna vibrator includes a radiation board. A partial region of the radiation board is bent downwards to form a plurality of support portions and a plurality of corresponding first hollowed-out holes, and a region between two adjacent first hollowed-out holes is bent downwards to form a plurality of bending portions and a plurality of corresponding second hollowed-out holes. The support portion serves to support and connect. At the same time, by forming the bending portion and the second hollowed-out hole on the radiation board, the isolation of the vibrator is optimized, and the cross polarization ratio after the vibrator being arrayed may meet conventional index without adding a boundary condition.

Abstract: The embodiments of the present disclosure provide an antenna vibrator and an antenna, and the antenna vibrator includes a radiation board. A center region of the radiation board is provided with a plurality of slits, and the radiation board is bent downwards at a peripheral region of each slit to form a support portion and a hollowed-out hole. The support portion serves to support and connect. At the same time, by forming the slit on the radiation board, the isolation of the vibrator is optimized, and the cross polarization ratio after the vibrator being arrayed may meet conventional index without adding a boundary condition.

Abstract: A method for generating a video synopsis may include: segmenting a video file into a plurality of video fragments. The method may also include extracting moving object information from the video fragment based on a distributed computing method and determining a plurality of index files based on the moving object information. The method may further include combining the plurality of index files and generating a video synopsis based on the moving object information and the combined index file.
