Tunable loop-dipole RFID tag antenna for dentures

摘要

A radio frequency identification (RFID) transponder for use in dentures is provided. The RFID transponder includes a passive RFID microchip configured for storing information related to a denture and a loop dipole antenna configured for sending the information in response to receiving a signal from an RFID reader. The loop dipole antenna in turn includes a wire forming a loop structure and a set of dipole arms going out from the loop structure. Each end of the set of dipole arms is folded at least once to form at least one meander and the dipole arms follow a shape of the denture. The RFID transponder also includes at least one tuning patch configured for tuning input impedance of the loop dipole antenna. The RFID transponder is embedded in the denture and the passive RFID microchip is electrically coupled to the loop structure.
