Folded Dipole RFID Tag Antenna Design for Implant Identification

25530

Exchange of information by placing suitable RFID (Radio Frequency Identification) tags on prosthetic implant which can replace defective biological tissue in human body, has begun to take its place among today’s biotechnological researches. Especially orthopedic implant placement and modification stages, both information of patient and applied implant moves with the patient, while reducing cost and time, improves data reliability according to current systems. So in this study, to achieve efficient target data transmission, design of antenna which is the most critical part of RFID tag and can run on knee implant is studied at 2.45GHz ISM band. Microstrip folded dipole antenna was preferred in design step and it was realized in the possible smallest size which can be applied on this implant. FR4 (Fire Resistant 4), a common substrate, was chosen for antenna designing and realizing. The antennas having the same geometry were modeled and compared in measurement for related tissue and free space environment respectively. According to measurement results, values of antenna gain, bandwidth and return loss are obtained applicable for target tissue environment.
