A main control unit determines a plurality of first distances and a second distance between the RFID reader and the RFID tag based on the first phase angle and the second phase angle, and select one of the plurality of first distances with respect to the determined second distance as a final distance.

Abstract: A radio frequency identification (RFID) transponder may include a substrate and a device. The substrate may be in communication with a controller and an antenna, and the antenna is arranged to receive radio frequency signals. A first side surface of the substrate may include a capacitor. The device may be detachably coupled with the substrate via a conductive member positioned between the structure and the capacitor of the substrate, and the conductive member may be within a desired proximity of the capacitor. The structure may be attached to an attachment surface so that an attachment strength between the structure and the attachment surface may be greater than a force required to decouple the structure from the substrate. When the structure is decoupled from the substrate, the conductive member separates from the capacitor, disabling the transponder.

Abstract: A radio-frequency identification (RFID) tag with improved sensitivity includes an antenna that receives a radio-frequency (RF) signal and wireless power from an RFID reader. The RFID tag further includes a circuit that varies a reflection coefficient of the antenna to transmit a reflected signal to the reader, the reflected signal having periods of high reflectance when a relatively high amount of the RF signal is reflected, and low reflectance periods when a relatively low amount of the RF signal is reflected. The reflectance of the antenna is sufficiently low during the high reflectance periods to enable wireless power reception during the high reflectance periods.
