Abstract

Wireless Body Area Network (WBAN) requires only a minimum amount of drive procedure with small array message and wide volume is obtainable by Ultra-Wide Band Technology. The humanoid physique presence carries tremendous difficulties for the plan of the propagation model as well as the wearable antenna in this system. To start with, the combination amid the wearable aerial and the humanoid physique must be considered even within the preliminary stages of the layout, with a purpose to be able to cope with each in all likelihood degrading performance of the antenna due to physique and the probability of revaluation for the physique. Later, the transmission medium of the Wireless Body Area Networks is controlled through the non-stop motion of the human body, as a result of the dissipation of the electromagnetic waves at different intervals. Many scholars are involved in the above subject then certain considerable development has been completed lately. The present article recollects today's consequences in the zone of aerials fixed in the physiques, transmission medium and then individual software in Wireless Body Area Network systems. This review discloses the major improvements of physique aerials involved by the part of fixable in the physiques and non-fixable in the physiques Ultra-Wide Band method then their applications in the Wireless Body Area Network device and methods for reducing SAR in them.

Key words: Specific Absorption Rate, Ultra-wideband Antenna, Wearable Antenna, On-Body Antenna.
