Abstract
Systems and methods for improvement in transmission antenna design and, more particularly, for rapid determine phase determination of incoming signals are described herein. In some embodiments, a phase detection system is described. The phase detection system includes a phase detection apparatus and a control system. The phase detection apparatus includes a phase shifting element and a phase detector element. The phase shifting element is configured to phase-shift a reference signal multiple times per detection cycle. The phase detector element is configured to compare an incoming signal to multiple phases of the phase-shifted reference signal during the detection cycle, and generate an output indicating a relative phase difference between the incoming signal and the phase-shifted reference signal for each of the multiple phases. The control system is configured to determine a relative phase of the incoming signal based, at least in part, on the outputs.
