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. ## Claims ### Claim 1 A communication system, comprising: an array of lenses having at least a first lens and a second lens; wherein the first lens has a first RF element oriented to produce a first output beam, and a second RF element oriented on at least one of the first lens and the second lens to produce a second output beam; wherein the first RF element is configured to rotate about a first virtual axis by a first distance, and the second RF element is configured to rotate about the first virtual axis by a second distance; and a third lens having a third RF element oriented to produce a third output beam, and a fourth RF element oriented with respect to at least one of the first, second, and third lenses to produce a fourth output beam. ### Claim 2 (depends on 1) The communication system of claim 1, wherein the first distance and the second distance are equal. ### Claim 3 (depends on 1) The communication system of claim 1, wherein rotation of the first RF element about the first virtual axis is in a direction opposite to rotation of the second RF element about the first virtual axis. ### Claim 4 (depends on 1) The communication system of claim 1, wherein the third RF element is configured to rotate about a third virtual axis by a third distance, and the fourth RF element is configured to rotate by about a fourth virtual axis by a fourth distance. ### Claim 5 (depends on 4) The communication system of claim 4, wherein the third distance and the fourth distance are the same. ### Claim 6 (depends on 4) The communication system of claim 4, wherein the third distance and the fourth distance are different. ### Claim 7 (depends on 1) The communication system of claim 1, wherein at least the first RF element and the third RF element are configured in a staggered arrangement. ### Claim 8 (depends on 1) The communication system of claim 1, wherein at least one of the first RF element, the second RF element, the third RF element, and fourth RF element is configured for dual-polarization. ### Claim 9 (depends on 1) The communication system of claim 1, wherein the first RF element is positioned so that a center of a radiation pattern emitted by the first RF element is directed towards a center point of the first lens. ### Claim 10 (depends on 1) The communication system of claim 1, wherein the first lens comprises a substantially spherical lens. ### Claim 11 (depends on 1) The communication system of claim 1, wherein at least 50% of the surface area for the first lens conforms to a shape of a sphere. ### Claim 12 (depends on 1) The communication system of claim 1, wherein at least one of the first, second, and third lenses is substantially cylindrical. ### Claim 13 (depends on 1) The communication system of claim 1, wherein the first lens comprises a dielectric material.
