Characterization of the Fat Channel for Intra-Body Communication at R-Band Frequencies

open access: yesSensors, 2018
In this paper, we investigate the use of fat tissue as a communication channel between in-body, implanted devices at R-band frequencies (1.7–2.6 GHz). The proposed fat channel is based on an anatomical model of the human body.
