Abstract: A system includes an antenna, a modulator, and a controller. The modulator may be operatively connected to the antenna. The modulator may be configured to send, a signal to a wireless device via the antenna. The modulator may have an output impedance. The controller may be connected to the output of the antenna. The controller may include a detector and a driver. The detector may be configured to determine the amplitude of a response from the wireless device. The driver may be configured to scale the output impedance responsive to the amplitude.
