摘要： A multiple-antenna positioning system with a single drive element, providing reduced weight and complexity over systems that have a drive element for each antenna. In certain examples, each antenna can be coupled with a rotating spindle, with each antenna spindle being coupled with a pair of link arms. By driving a single drive spindle, each of the antenna spindles in the system can be rotated by the associated pair of link arms. The link arms can have an adjustable length, such as through a turnbuckle mechanism, to reduce backlash in the system, and in some examples can apply a preload to the system. By reducing backlash, the multiple antenna positioning system can have improved responsiveness to a rotation of the single drive element, as well as improved stability of the positioning of each antenna when the drive element is held in a fixed position.

摘要翻译： 具有单个驱动元件的多天线定位系统，在具有每个天线的驱动元件的系统上提供减小的重量和复杂性。 在某些示例中，每个天线可以与旋转主轴耦合，每个天线心轴与一对连杆臂相连。 通过驱动单个驱动主轴，系统中的每个天线主轴可以由相关的一对连杆臂旋转。 连杆臂可以具有可调节的长度，例如通过螺丝扣机构，以减少系统中的反向间隙，并且在一些示例中可以对系统施加预载荷。 通过减少间隙，多天线定位系统可以改善对单个驱动元件的旋转的响应性，以及当驱动元件保持在固定位置时每个天线的定位的改进的稳定性。
