Claim Text:
1. A base station for providing air-to-ground (ATG) wireless communication over various altitudes of an ATG cell, the base station comprising: a first antenna array comprising one or more antennas configured to form a first cell coverage area extending substantially from the horizon up to a first elevation angle away from the first antenna array to a predetermined distance from the first antenna array along each of a plurality of directions from the base station; a second antenna array configured at an uptilt elevation angle to form a second cell coverage area extending at least from the first elevation angle to a second elevation away from the second antenna array, wherein the first cell coverage area and the second cell coverage area are concentric to define the ATG cell at least to the predetermined distance along each of the plurality of directions from the base station and up to a predetermined elevation; and a patch antenna disposed concentric with the first and second antenna arrays to provide a third coverage area from the second elevation to at least a point directly above the base station at the predetermined elevation, wherein the first, second, and third coverage areas combine to define the ATG cell to provide continuous coverage within the ATG cell to the predetermined distance and to a height of the predetermined elevation, the predetermined elevation being about 45,000 feet.
