This invention describes a method for an antenna system to transmit radio signals using beams of different widths. It can send a focused, narrow beam by applying a specific set of instructions to all its antennas. To create a wider, more spread-out beam, the system still uses all its antennas but divides them into smaller groups, which are then directed to point in slightly different directions, causing their combined signal to broaden into the desired wider beam.
Why it matters: Filed before the widespread adoption of 5G, this invention's dynamic beam broadening capability is now a core requirement for efficient initial access and coverage in modern cellular and satellite communication systems. Advances in RFIC integration and computational power have made such complex beamforming more practical.
