Antenna polarization mismatch in BAN communications

In any wireless communications, antennas and propagation are key concerns. Their importance becomes more significant for in/on-body wireless applications. Body Area Network (BAN) links lead to propagation problems considerably different from free space wireless communications due to presents of body tissues, body movements, and enormous figure of body poses. Therefore, to ensure the efficient performance of body area wireless communication the electromagnetic wave propagation need to be characterized and modeled for reliable communication system with respect to environment, antenna, body postures, and body movements. This paper discusses on polarization mismatch due to body movements between on-body transmitting antenna and off-body receiving antenna.
