Abstrakt:
The propagation of signals for ultra wide band (UWB) systems is analyzed. Signals can be
substantially affected due to electromagnetic wave propagation through walls or similar obstacles.
New experimental results of anechoic-chamber measurements and numerical simulations for frequency band from 4 to 8 GHz are analyzed and compared. That is briefly compared with the
previous experiments, performed in real scenarios (walls between laboratories or offices) in various
frequency bands and time domain measurements, which have been done using very short pulses.
Experiments performed for frequency and time domains demonstrated that the numerical
simulations, which are very fast, could be reliable, when suitable wall parameters are used.
