The body area network (BAN) is a wireless technology, which play an important role in very short range wireless communications and find a wide variety of applications such as WiMedia for relaying information gathered by biological sensors on body. The ultra wideband (UWB) technology is suitable for BAN system because of transmission by impulse radio and low power. However, signal distortion due to human body effect in human body-ultrawide band (HB-UWB) channel must be study. In this study, we evaluate HB-UWB channel which serious disturbed by the distortion. The distortion can cause extremely poor signal quality to wireless transmission channel even in free space because of the antenna characteristics and waveform distortion. Thus, the understanding of the effect from characterization of antenna and waveform effect is important. The measurement data of distortion analysis due the antenna and human body of HB-UWB for WBAN were presented in this research report. The receiver waveform template was present to maximize system signal to noise ration. The equation of Friis had been used to evaluate the results. The proposed method is practical for the HB-UWB evaluation, UWB antenna design, and provide more precision to identify the waveform distortion. The results can apply for the design of wireless medical devices which focus on the effect of human body.
