Abstract :
In this paper, the effect of the orientation of implantable antennas on their performance inside the body model is studied. The reflection coefficient, gain, radiation efficiency and SAR values are investigated for three different antenna orientations in an asymmetric anatomical body model. It is found that the antenna performance is closely linked to the orientation of the antenna even for the same position inside the body. The analysis in this paper provides a valuable insight into the accurate evaluation of implantable antennas.
