Tunable loop-dipole RFID tag antenna for dentures

A radio frequency identification (RFID) system for detecting and identifying lost dentures in a facility, comprising:

• at least one reader deployed in fixed locations in a facility and configured for transmitting a first signal and detecting from a distance of at least one feet a second signal transmitted from an RFID transponder embedded in a denture in response to receiving the first signal;
• a first server located within the facility and configured for communicating with the at least one reader over a network in the facility and for controlling operations of the at least one reader, wherein the at least one reader sends an alert to the first server when it detects the second signal from the RFID transponder and wherein the first server is further configured for sending a message when it receives the alert from the at least one reader;
• and
• a second server located outside of the facility and configured for receiving the message and for relaying the message by converting the message to at least one of an email, a text message, a pager message, and a voice message.

A method of detecting and identifying lost denture in a facility, comprising:

• transmitting a first signal at a reader deployed in a fixed location in a facility;
• detecting from a distance of at least one feet a second signal transmitted from an RFID transponder embedded in a denture in response to the first signal;
• and
• sending over a network in the facility an alert to a first server located within the facility in response to detecting the second signal from the RFID transponder,
• wherein the second signal includes information related to the denture including an identification of the denture owner and at least one of (1) the denture owner's medical records and (2) data pertinent to the denture owner's lost and found history including data and time when the denture was lost and place where it was found.
