1. A method comprising:
directing, from a detection device, a radio-frequency signal to a wireless implantable medical device that is coupled to the detection device via non-inductive electrical radiative coupling, the radio-frequency signal being directed to the wireless implantable medical device while an impedance of an antenna of the wireless implantable medical device is actively modified between at least two different levels;
monitoring, at the detection device, a plurality of shifts in power of a plurality of reflections of the radio-frequency signal caused by the modification of the impedance of the antenna of the wireless implantable medical device; and
generating feedback regarding a location of the detection device in relation to a location of the wireless implantable medical device based on the monitored shifts in power.
