Implantable Monopole Antenna for Bone Fracture Monitoring

Abstract

A particular region of interest in the field of antenna is wearable antenna or implantable antenna. As the medical field is growing in the developing world the advancement of the devices in the medical field also grows, which increases the interest and opportunity for the implantable antennas. This type of antennas helps the physicians to diagnose and treat their patients in the most efficient manner. These antennas are light weight and easily wearable. The antenna designed here is implanted in the patient’s body in the affected area. The antenna works at a frequency between 2.4 Ghz to 4Ghz range. The antenna uses two monopole antennas. The two monopoles are placed on either sides of the impaired area. The signal from the one monopole antenna reaches the other antenna. In the path between two poles the injury in the bone is present. As a matter of fact that each and every material have different dielectric constants, the system using these values to keep track on the healing process. As the antenna is designed for 2.4 Ghz, the monopole’s length is about to be 3cm also the ground plane for the monopole antenna is designed for 4 x 3.4cm. So, this antenna will be more compatible to use. The S-parameter of the .port 1 and port 2 will help to keep track on the healing process of the bone.
