Wireless Body Area Networks have gained a large interest in the last decade. Antennas are a key component of such systems, as their characteristics and quality are predominant for the quality of the entire link. In this contribution, two major aspects of W-BAN antennas will be investigated: their coupling to the wearer, and their efficiency. The former is best characterized by the Specific Absorption Rate. Two scenarios will be considered, the first being a narrow band link at 380 MHz for security and rescue applications, the second an Ultra- WideBand link.
