Study of Helical Antenna as a Bone Fracture Sensor

Bone fracture is one of the most commonly seen health problems. In this study, it is aimed to detect bone fracture using a helical antenna placed without any contact with the bone. The basic idea of the study, which was carried out with a finger-type bone, is to observe the changes in the scattering parameters expressing the ratio of incident and reflected electromagnetic waves. The analysis of the system showed that the scattering parameters and the operating frequencies with broken and intact biological structures are different from each other. Besides, the operating frequency of the system is determined to vary according to the status of fracture in the bone and presented as a distinctive finding.
