Experimental study of ultra wideband human body channel

Abstract

This paper a study of UWB human body channel. The human body is more complex than other application. Therefore, to understand human body channel is so important. The analysis is based on the extension Friis' transmission formula that uses to characterize the WBAN channel transfer function. The rectangular passband waveform is used as UWB transmitted waveform. The channels of 5 positions on human body are measured by using vector network analyzer (VNA). The frequency channel transfer functions, power delay profile (PDP) and path loss are shown. The results are discussed in conclusion.
