Abstract
Implantable medical devices are mainly in use for the wireless electronic health devices and remote home care applications because of their miniature techniques and low-power consumption integrated circuits. The demand for bio-medical applications that employ wireless telemetry systems has increased significantly. Antennas can be implanted into human bodies to form a bio-communication system between medical devices and exterior instruments for short-range bio-telemetry applications. A compact antenna is being implanted in dental applications. The antenna consists of Archimedean spiral antenna and a Hilbert-based curve gives high gain. In this design two Hilbert based curves and one spiral antenna is embedded. This 3D folded antenna is implanted in teeth. It gives uni-directional radiation pattern and eliminates the back radiation. Due to unidirectional radiation the power loss is reduced. In Archimedean spiral antenna FR4 material is used as a substrate with dielectric constant 2.2. Here probe feed technique is used to excite the current. Simulation is done by using HFSS software. Shortening wall technique is used to enhance the bandwidth. The simulated antenna performs high gain (>6 dB), return loss (<−10 dB) and broad bandwidth. This antenna can be used for bio-medical applications.
