- Description
- An essential part of wireless body area networks (WBANs), like for any wireless system, is the transducer that converts electrical signals into electromagnetic waves and vice-versa. This has been done by antennas for medium-long range communications or inductive coils for very short range communication. Usually the communication in WBAN is either short range or medium range. The on-body and implanted sensor nodes are essentially small devices that are, at most, of the size of a standard mobile phone. There are matured enough technologies to design low-profile antennas for mobile wireless devices. The transformation of those technologies into WBAN applications will be discussed. One of the main concerns of antennas in WBAN is the interaction of near field electric and magnetic fields with the human body. This phenomenon is responsible for significant changes in antenna characteristics, and researchers have found methods to mitigate these effects for on body antennas. Some of these methods, especially the antenna shielding, will be discussed. It is even more challenging to design inbody (implanted) antennas with surrounding dissipative body tissue at high frequencies. Recent research into the efficiency enhancement of implanted antennas will be discussed in this chapter. Widely used classes of antennas in wideband and narrowband WBAN, including volume conduction antennas, will be presented as examples. The commonly used design and experimental methods of WBAN antenna evaluation will be discussed. A brief overview of antenna theory and modern simulation techniques will be incorporated, where necessary, for the readers who are not familiar with the material.
