Abstract
A disclosed transponder arrangement includes a transponder integrated circuit (IC), an inductive loop, and a dipole antenna. First and second wires are coupled to the transponder IC and have portions configured for different levels of electrical coupling between one another. Engagement of the inductive loop with an induction portion of the dipole antenna induces current flow in the inductive loop in response to the dipole antenna resonating from a radio frequency (RF) signal, and disengagement makes the transponder IC non-responsive to the RF signal. Depending on a level of electrical coupling between the first and second wires, the transponder IC generates an RF signal that encodes either a first value indicating partial engagement or a second value indicating full engagement in response to the current flow in the inductive loop.
