  • Antenna adjustment system and base station
    Patent number: 10505265
    Abstract: An antenna adjustment system and a base station, where the antenna adjustment system includes an inertial feedback unit configured to detect a swing angle of an antenna when the antenna swings with a housing, and send an angle signal to a controller, an actuator and an elastic element configured to control an auxiliary board to rotate back in a direction opposite to a swing direction of the housing in order to counteract deflection caused by swing of the housing of the antenna fastened to the auxiliary board. The actuator is driven by the controller based on the angle signal. Therefore, a position of an antenna can be adjusted with swing of the antenna such that signal sending stability of the antenna can be ensured.
