Abstract: A method for correcting antenna phases includes a beam angle calculating step, beam angle adjusting step, antenna emission measuring step and beam angle correcting step. The method involves comparing a difference between the ideal antenna phase value and the measured beam angle value, determining according to the difference that the beam direction of the antenna needs to be corrected, and adding the difference to a current ideal antenna phase value in the algorithm to calculate another ideal antenna phase value for being sent to the phase control circuit and used in executing the beam angle adjusting step in a next instance of measurement process until the beam angle correcting step finds the difference which requires no correction of the beam direction of the antenna. Therefore, temperature-dependent errors do not occur to beam directions, thereby enhancing the communication efficiency of an antenna system.

Abstract: A smart communication system, for adaptive antenna beam-forming for a link of a data transmission device to at least a user device, is introduced. The system comprises a plurality of positioning devices, a data transmission device, and a cloud server. The positioning devices send a plurality of positioning signals to the at least a user device to effectuate positioning. The data transmission device is for use with adaptive antenna beam-forming to provide wireless communication. The user device communicates with the cloud server through the base station unit. The cloud server receives positioning information of the at least a user device, generates a control signal for beam-forming in accordance with the positioning information, and sends the control signal to the data transmission device. The data transmission device controls the beam-forming of the data transmission device in accordance with the control signal.
