Patent ID: 7613482

Claim:
A hybrid wireless network system for steering antenna beams, comprising: an antenna array, receiving at least two RF signals; an analog subsystem comprising: a step leveling device coupling to the antenna array; a magic-Tee coupler connected to the step leveling device for calculating a difference signal and a sum signal based on the two RF signals; and a phase-sensing comparator for calculating a polarity data based on the comparison of the difference signal and the sum signal; and a digital subsystem comprising a transceiver and a receiver, estimating a direction-of-arrival (DOA) based on the difference signal and the polarity data, and generating weights based on the DOA; and wherein the step-leveling device receive the weights from the digital subsystem, in form of a feedback control, to apply the weights on the two RF signals respectively; wherein the digital subsystem repetitively calculates new weights to update a beam pattern of the antenna array until the DOA approaches null.
