1. A system for supporting air-to-ground (ATG) wireless communication in various cells, the system comprising:
a plurality of ATG base stations, each of which defines a corresponding radiation pattern focusing energy toward the horizon, wherein the ATG base stations are spaced apart from each other to define at least partially overlapping coverage areas forming an ATG communication layer defined between a first altitude and a second altitude; and
an antenna assembly of an aircraft, the antenna assembly being configured to communicate with the ATG base stations in the ATG communication layer above a terrestrial communication layer defined by terrestrial transmitters configured to communicate with user equipment located on the ground in a ground communication layer below the first altitude,
wherein the antenna assembly comprises a blade antenna,
wherein the blade antenna comprises multiple transmission elements having selectable directivity, and
wherein the blade antenna is configured to employ side lobe suppression techniques to reduce interference with the terrestrial transmitters.
