Abstract

The applications of a wireless body area network (WBAN) have been expending in medical services, police and military agencies, sports training, entertainment, wearable computing, and so on [1]. In WBAN applications, antennas are required to have a small size, low human body effect and low specific absorption ratio (SAR) [2]. The human body has a high dielectric constant with a high loss tangent and low conductivity at the microwave frequency band. Therefore, the gain and radiation efficiency of an antenna can be deteriorated when an antenna is operated on or in the human body.
