Abstract

A beam adjustment assembly includes a phase shifter and a connecting plate. The phase shifter includes a circuit board and main dielectric slabs configured to shift a phase. The circuit board is provided with a first strip and a second strip that are spaced. The first strip and the second strip are configured to respectively connect to radiating elements of an antenna. The connecting plate is slidably assembled on the circuit board and is configured to control an electrical connection between the first strip and the second strip. When sliding, the main dielectric slab can push the connecting plate to slide to control a quantity of radiating elements in the antenna system. The sliding of the main dielectric slab in the phase shifter is used as a driving mechanism of the connecting plate.
