A denture implanted UHF RFID tag antenna is proposed. The limitation on antenna size means that a low-loss and compact antenna including matching circuit is necessary to increase the tracking distance. To reduce the loss brought by reflection, a partially exposed folded dipole antenna with gamma matching is utilized. The denture implanted RFID tag is fabricated by using materials utilized in the exact denture such as metal wire and resin. Furthermore, the RFID operation properties of the denture implanted tag are evaluated by changing the parameters of antenna structure. Based on the measurement result, the new proposed structure reduce the reflection loss from the mismatch between RFID chip and small antenna, which provides enough energy for communication. Also, this proposed antenna structure provides a brand new idea for designing antenna in medium.
