Abstract

This paper presents the ultra wideband propagation (UWB) channel on two path model with laptop computers. The UWB pulse with specific center frequency and bandwidth is used for transmitted signal. Complex form Friis' transmission formula is applied for the UWB propagation channel. The received signal is evaluated. The UWB path loss is defined as the ratio between the maximum amplitude of the transmitted and received signal waveforms. For the data processing, the path loss of two path model is considered for the 0.10 and 0.20 m antenna heights. The double linear regression for the path loss is modeled by using the minimum mean square error (MMSE) and first Fresnel zone break-point curve fits. The characteristics of the path loss function of the antenna heights are evaluated and discussed in this paper.
