Miniaturized Planar Implanted Spiral Antenna Inside the Heart Muscle at MICS Band for Future Leadless Pacemakers

This paper presents a miniaturized planar spiral implanted antenna inside the heart tissue for future leadless pacemakers. The implanted antenna is designed for Medical Implant Communication Service (MICS) band (402-405 MHz). The surrounding medium permittivity and tangent loss effect on the implantable antennas are also investigated. Moreover, the forward transmission coefficient between two implanted spiral antenna is analyzed. The investigation has been carried out using EM full-wave simulations.
