The subject of this research work is the design and development of novel applications and services targeting wireless body area networks for health and medical-care applications to be used in the healthcare facility and home. The project focuses on realizing a number of areas including a channel model for tissue implanted device and onbody sensors for wireless body area networks. A central component of wireless body area networks is an antenna and there are several issues to consider when designing an antenna for WBAN’s applications, including power consumption, size, frequency, biocompatibility and the unique RF transmission challenges posed by the human body.
