Abstract: A method for inductively coupled communication is described. The method includes applying a carrier signal at a carrier frequency to an antenna circuit. The antenna circuit includes an antenna and a matching network that resonate at a resonant frequency. The method also includes measuring a looped-back signal over a range of impedance values. The looped-back signal includes the carrier signal received by a receiver coupled to the antenna circuit. The method further includes setting a calibrated impedance as an impedance configuration that produces a resonance peak in the looped-back signal.
