Abstract

See full text

Systems and methods for antenna impedance matching provide an integrated circuit (IC) configured to be placed proximate an antenna that includes a sensor based on a coupler having forward and reverse power detectors for detecting an impedance at the antenna and provides dynamic impedance matching. Further, exemplary aspects of the present disclosure contemplate using a single wire bus capable of supplying power and providing a bidirectional serial communication link to allow communication between the IC of the present disclosure and a control circuit (e.g., a bridge or transceiver). Further aspects of the present disclosure contemplate providing systems and methods for calibrating the IC at production. Further, the accuracy of the impedance sensor may be dependent on accurate determination of power and phase difference between forward and reverse coupled signals, and a system for removing an offset between the forward and reverse power detectors is disclosed.
