Abstract
A coupling loop or antenna is provided that can be used with a system that determines the resonant frequency of a sensor by adjusting the phase and frequency of an energizing signal until the frequency of the energizing signal matches the resonant frequency of the sensor. In one embodiment orientation features are provided for positioning the coupling loop relative to the sensor to maximize the coupling between the sensor and the coupling loop.
