Abstract

The present invention provides an antenna assembly and an electronic device. The antenna assembly comprises a guiding component, a plurality of radiators, a plurality of feeding sources, and a drivingmechanism; the plurality of radiators are slidably disposed on the guiding component at intervals; each of the radiators is electrically connected to at least one of the feeding sources; the drivingmechanism is connected with the radiators and the guiding component; and the driving mechanism is used for driving the radiators to move along the guiding component, so that a distance between two adjacent radiators can be changed. The distances between the adjacent radiators are adjusted, so that the maximum radiation directions of the radiators can be adjusted, and therefore, the scanning of antenna beams can be realized, and the wide coverage of the high-gain antenna can be realized, and at the same time, the plurality of radiators slide on the guiding component, and do not occupy a largerthree-dimensional space; and a large number of phase shifters are not needed, and therefore, costs can be saved.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to an antenna assembly and electronic equipment. Background technique [0002] In the application of the array antenna, since the gain of the antenna is required to be high, the beam of the antenna is narrowed, and the coverage angle of a single beam of the antenna becomes smaller. To solve the problem of wide coverage of high-gain antennas, beam scanning is the most widely used technical method at present. There are currently two types of beam scanning, one is to achieve mechanical scanning of the antenna beam by rotating the antenna front, and the other is to provide different feed phases for different antenna elements to achieve electrical scanning of the antenna beam. However, the first method requires the rotation of the antenna array, which needs to provide a lot of space. The second method needs to add a large number of phase shifters, and the cost is relative...
