Abstract: A system and method for antenna optimization for wireless broadband communication is provided. Such an enhanced antenna array includes higher-gain antenna and lower-gain antenna. The beamforming antenna, both higher-gain and lower-gain, are designed to be able to transmit to and receive from another transceiver. The higher-gain antenna may be designed to form a more directional beam substantially closer to the horizon; whereas the lower-gain antenna is capable of forming a less directional beam at a distance further from the horizon. In both cases, the antenna may form their respective beams anywhere in the 360 degrees horizontally around the antenna array. The higher-gain antenna may include a coverage area from the horizon to a substantially acute angle from the horizon in the vertical direction. In contrast, the lower-gain antenna may have coverage from the substantially acute angle from the horizon to substantially vertical. The substantially acute angle may be approximately 10 degrees in some cases.

Abstract: A system and method for wireless data delivery is provided. The communication may be between the antenna arrays of an airborne platform (such as aircraft) and a surface base station. The antenna arrays may generate a plurality of directional synchronization beams directed in at a plurality of corresponding spatial directions. Other antenna arrays receive the directional synchronization beam and respond in kind, providing the original antenna array a way to determine directionality of the other antenna arrays. The antenna arrays may then receive a training beam. The training beam includes known data, such as a Fourier Matrix, which may then be utilized to generate weights. Weights may then be utilized to modify either of the phase or amplitude of a base signal which is then sent to each of the elements of the antenna array in order to achieve directionality of the signal propagation.
