Abstract
A radio frequency antenna array uses lenses and RF elements, to provide ground-based coverage for cellular communication. The antenna array can include two spherical lenses, where each spherical lens has at least two associated RF elements. Each of the RF elements associated with a given lens produces an output beam with an output area. Each lens is positioned with the other lenses in a staggered arrangement. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically phase compensate the output beams produced by the RF elements based on the relative distance between the RF elements.
Claims11
A method of tracking an object moving across a first region of sky, comprising:
- providing a first RF element moveable about a first lens, and a second RF element movable about a second lens;
- creating a first overlapped beam by phase shifting (a) a signal beam passing through the first lens to/from the first RF element relative to (b) a signal beam passing through the second lens to/from the second RF element;
- and
- further phase shifting the signal beams to/from the first and second RF elements to track the object as it moves across the first region of sky.
