Beamforming – Definition and Pronunciation
What is Beamforming?
Beamforming techniques entail techniques where multiple feed horns are energized with signals constructed on a “network,” called beam-forming network (BFN), to alter the phase of the distinct feeds such that constructive interference can be used either to generate a large shaped beam (shaped to a specific geography), or to generate a pattern of spot beams. If a dynamically-reconfigurable pattern is desired, then BFNs can be used as a core component of the multiple beams antennas; however, BFNs add weight and complexity.
Examples of Beamforming
Numerous narrow beams may be formed from a relatively few elementary feeds by a process known as beamforming (described, e. g., in US Patent numbers 5 115 248 and 5 784 030).

The solution to these problems is simple: We need new satellite technology. And it’s arriving. Wealthy private investors and brilliant young engineers are dragging satellites into the 21st century with inventions including “flocks” of “nanosatellites” that weigh as little as three pounds; flat, thin antennas built from advanced substances called “metamaterials”; and “beamforming,” which steers radio signals using software.
