Design Concerns for In-body Antennas Based on Frequency Analysis of Fundamental Radiation Limitations

Anja Skrivervik, Denys Nikolayev, Zvonimir Sipus

Fundamental radiation limitations of in-body or implantable antennas should give us an estimate on the feasibility of some desired system. It was shown that near-field effects and distance to the body - freespace boundary are critical aspects, while the sh ...

Optimal Frequency of Operation and Radiation Efficiency Limitations of Implantable Antennas

Anja Skrivervik, Denys Nikolayev, Zvonimir Sipus

Fundamental limits on radiation performance of implantable antennas serve as the design quality gauge, facilitate the choice of the antenna type, and provide simple design rules to maximize the radiation performance. This study obtains the limits using two ...
