SAR Reduction of the Implanted Meandered Antenna with Two Novel Antennas

S. M. T. Mirrahimi, A. Keshtkar, and A. R. Bayat

Abstract—One of the safety important limitations in the designing of the implanted antennas is the specific absorption rate (SAR). With respect to application of ANSI SAR limitation it should be 1.6 (W/Kg) for one gram (1-g) of tissue. In this paper a method have been used to reduce the SAR value. First, we utilized a meandered implanted antenna and simulated by using finite difference time domain (FDTD) method and then by using the Non-uniform Width Radiator method we proposed two novel implanted antennas which are better than the first meandered antenna in the aspect of SAR limitation also they can be used in the frequency band (402-405MHz) of the medical implant communications service (MICS).

Index Terms—Biological tissue, implanted antennas, specific absorption rate (SAR).
