Abstract

Small implanted devices have been investigated with great interest for wireless medical applications due to the promise of different clinical usages in order to promote patient´s independence. In these implanted device systems, an antenna plays an important role as a part of transmitting and receiving power. Therefore, the research on the antenna for implantable device (implanted antenna) is important. In this study, we propose an implanted helical folded dipole antenna for short-range wireless communications. The antenna is designed to operate at 2.45 GHz, one of the industrial-scientific-medical (ISM) bands, and it is investigated by use of the finite-difference time-domain (FDTD) calculation. We have analyzed some performances of the proposed antenna and the results show that the proposed antenna can be a candidate as an implanted antenna.
