Effects of Blood Vessels on Fat Channel Microwave Communication

Abstract

This study aims to investigate the reliability of intrabody microwave propagation through the fat tissue in presence of blood vessels. Here, we consider three types of blood vessels with different sizes. We investigate the impact of the number of blood vessels and their alignment on the transmission of microwave signals through the fat channel. In our study, we employ two probes that act as a transmitter and a receiver. The probes are designed to operate at the Industrial, Scientific, and Medical radio band (2.45 GHz). For a channel length of 100 mm, our results indicate that the presence of the blood vessels may increase the channel path loss by $\tilde1.5$ dB and $\tilde4.5$ dB when the vessels are aligned and orthogonally aligned with the fat channel, respectively.
