A radio frequency antenna array uses multiple lenses, and mechanically movable elements, to provide ground-based and sky-based coverage for multiple object communication and tracking. The antenna array includes at least two spherical lenses, where each spherical lens has at least two associated RF elements. A third lens is added, along with at least two additional RF elements to narrow and track the overlapped beams from the first and second lenses. Each lens also includes a sub-controller configured to adjust a phase of the signals produced by the RF elements. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically configure the phase shifter to modify a phase of the output signals from the elements based on the relative positions between the RF elements. The overlapped beams track independent targets, such as satellites, across an area.

A repeater has a spherical dielectric lens antenna, a donor feed unit supporting transmission and reception of signals through the lens antenna, a service feed unit supporting transmission and reception of signals through the lens antenna, and at least one interconnecting guided transmission medium providing a radio frequency transmission path between the donor feed unit and the service feed unit.

An antenna assembly includes a lens, a guide rail, an antenna array, and a phase shifter. The lens has a first refractive surface. The guide rail is a linear guide rail and is located on one side of the first refractive surface of the lens. The antenna array includes a plurality of radiating elements. The antenna array is slidingly connected to the guide rail. As the antenna array moves on the guide rail, a beam pointing direction of the antenna assembly moves in an extension direction of the guide rail, to perform mechanical beam sweeping within a first sweeping range in the extension direction of the guide rail. The phase shifter is connected to the plurality of radiating elements and is configured to adjust feed phases of the plurality of radiating elements, to perform phase modulation sweeping within a second sweeping range.
