This invention discloses a distributed beamforming method, system, and apparatus for low-Earth orbit satellites, comprising: acquiring ground user location information and satellites to be communicated with; calculating the transmission paths between multiple satellites and ground users and obtaining the superimposed signal of electromagnetic waves at the ground end; calculating the superimposed power distribution of the ground electromagnetic waves based on the superimposed signal; constructing an objective function that maximizes the average received power of all ground users and the fairness of ground users based on the calculated superimposed power distribution of the ground electromagnetic waves; calculating the optimal satellite and its corresponding initial transmission phase within the selectable set, indirectly controlling the transmission distance from the satellite to the ground end to control the final phase of the electromagnetic waves received by the receiver, thereby maximizing the overall power gain of multiple ground receiving terminals and the fairness among each individual ground user, providing ideal power gain regardless of the location of the ground user, and simultaneously covering multiple users.

The utility model relates to the field of router antennas, in particular to a router antenna with a folding function. The router antenna with the folding function comprises a router body, supporting frames, main antennas and auxiliary antennas, the supporting frames are arranged on the left side and the right side of the router body respectively, the main antennas are rotationally arranged on the front sides in the supporting frames respectively, and the auxiliary antennas are hinged to the rear ends of the main antennas respectively. According to the utility model, through the design of the main antenna and the auxiliary antenna, the signal receiving and transmitting capability can be effectively enhanced, the network performance is improved, meanwhile, the unique foldable design is very practical, and the router is small in size and convenient to carry and store in a folded state; and when the antenna needs to be used, the antenna is unfolded, the signal coverage range can be expanded, the use requirements of a user in different scenes are met, and portability and signal quality are both considered.
