SELF-STEERING ANTENNA ARRAYS

摘要

Methods and apparatus, including computer program products are provided for self- steering antennas. In one aspect, there is a method. The method may include receiving, at a plurality of antennas, phase shifted versions of a signal. The method may further include determining a phase relationship between the phase shifted versions of the signal. Based on the determined phase relationship, the method may include adjusting a phase of a first local oscillator to remove a phase difference between the phase shifted versions of the signal to change the phase shifted versions of the signal to being in-phase versions of the signal. The method may further include combining the in-phase versions of the signal to steer a beam to a transmitter.
