    • A universal joint comprising a pair of circular waveguide ball-joints and a slip-joint allows for simultaneous 3-axis rotation and 3-dimensional translation between an antenna and a stationary source. As such, the universal joint does not have to be physically aligned with the azimuth, and elevation, rotation axis of the antenna and mounted on the gimbal support, greatly simplifying the antenna steering mechanism. The universal joint allows the antenna to be mass-balanced in relation to the azimuth and elevation axis without adding any additional counter weights, thus reducing the size and power requirements of the azimuth and elevation rotation drive systems. Additional ball-joints may be provided to increase the allowed range of motion of the antenna.
    • 包括一对圆形波导球形接头和滑动关节的万向接头允许在天线和固定源之间同时进行3轴旋转和3维平移。 因此,万向节不必与天线的仰角和仰角旋转轴物理对准,并且安装在万向支架上,大大简化了天线转向机构。 通用接头允许天线相对于方位角和仰角进行质量平衡,而不增加任何额外的配重,从而减小方位角和仰角旋转驱动系统的尺寸和功率要求。 可以提供额外的球接头以增加天线的允许运动范围。
