Aims

Body-centric wireless networks are seen to be a central component in the 4th generation communication systems. Such networks have distinctive features in comparison to other available wireless networks due to the rapid changes in communication channel behavior on the body during the network operation. This series of lessons raises some important issues regarding antenna design and propagation channel characteristics, radio systems compatibility with such an environment and the effect that the human body has on these networks. Meanwhile, physical dimensions, directivity, mutual coupling and so on in antenna design, are classically constrained by the wavelength of the radiation involved.

Combined with complex on-body channel characteristics, extra issues may be raised related to human body presence and movement, such as resonant frequency detuning in narrow band systems, signal dispersion and variable gain in UWB network etc. These topics represent research and design challenges in antenna system for future body-centric wireless networks and also form the premise of these lessons.
