Characterization of the effects of the human head on communication with implanted antennas

The present work focuses on the characterization of the effects of the human head on communication with cranially implanted antennas for its eventual use in improving current communication methods. A realistic human head model with frequency dependent tissue characteristics is used to obtain a transfer function that describes the magnitude and phase of an electromagnetic wave as it propagates through the human head. This data, captured over a wide frequency range, is then approximated through the use of a modified version of the indoor propagation communication model for path loss which is used to successfully predict received power from cranially implanted antennas.
