    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.

    The body area network (BAN) working on IEEE 802.15.6 is a wireless short-range communication system that is smaller in coverage than the personal area network (PAN) IEEE802.15.3a. A wireless body area network (WBAN) is a wireless technology with a human body that is becoming a key part of short-range radio wave systems and wireless medical technology. The transfer function characteristics of the human body and the transmission loss due to the human body should be studied. Short-range radio wave applications with a human body are more complicated than additional uses. Therefore, realizing the distribution channel characteristics of the human body with ultra-wideband (UWB) technology is important. UWB technology has a very large bandwidth, low power, and low cost, which can be used in shortrange systems. In this paper, we present the characterization measurement data of the UWBHB channel transfer function based on the human body effect with and without human body in WBAN system. In this study, we maximize the signal-to-noise ratio (SNR) and contemplate the matched filter at the receiver. The outcomes are analyzed and evaluated on the basis of Friis' formula. The proposed method achieves very precise results and is convenient for the evaluation and design of the waveform of WBAN transmission in wireless medical applications and BAN systems, mainly focusing on the input waveform effect.

    Wireless communication systems have become important in daily life such as wireless body area network (WBAN). An ultra-wideband (UWB) technology is chosen to be used for short-range communication scenarios, low-power and high data rate technology which accommodates appropriate technology in WBAN. In this paper, we design a printed circular monopole with coplanar waveguide (CPW) fed for WBAN with common frequency band following FCC common band (7.25-8.5 GHz). The antenna structure is simple, using FR4 circuit board (PCB) with overall size of 18 × 20 × 1.6 mm<sup>3</sup>. The simulation and experiment results show that the proposed antenna achieves good impedance matching and stable radiation patterns over operating bandwidth of 6.8-12.34 GHz. Moreover, the authors evaluate UWB antenna in two scenarios are free-space and with human-body to consider the antenna performance in time domain. © 2013 Springer Science+Business Media Dordrecht(Outside the USA).
