The RFID transponder may modulate an amplitude of the backscattered signal by controlling an input impedance of the RFID transponder. The input impedance may be controlled by switching a load in and out of a receive path of the RFID transponder. The input impedance of the RFID transponder may be controlled by switching between a plurality of feed points of the leaky wave antenna. Each of the plurality of feed points may be located in a different position in the resonant cavity of the leaky wave antenna.
