Characterization of ultra-wideband antenna with human body

This work presents the characterization of an ultra wideband antenna with the human body. An experiment of the antenna transfer function needs the three-antenna method for calibrating the reference antenna. The results are used to evaluate the transmission gain based on the extended Friis' transmission formula. A matched filter is considered at the receiver side to maximize the SNR for evaluation. This technique gives very accurate results and is very useful for the design and evaluation of UWB impulse radio transmission systems, especially for the evaluation of waveform distortion effects.
