Abstract :
In this paper, the evaluation of two path model in ultra wideband (UWB) propagation channel with laptop computers for personal area network (PAN) is proposed. The UWB pulse with the specific center frequency and bandwidth is used for the transmitted signal. Complex form Friispsila transmission formula is applied for the UWB propagation channel, then 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 height is evaluated and discussed in the paper.
