| Abstract(in English) | Ultra wideband (UWB) signal propagation was measured and characterized in comparison with narrowband inside a typical some satellite, considering the potential to realize ultra-high-speed wireless bus connection with in mass and layout restrictions. Spatial distributions of UWB and narrowband path gain, delay profiles, and delay spreads within the mockup were derived from frequency-domain responses (from 3.1 to 10.6GHz) measured with a vector network analyzer and UWB monopole antennas. While narrowband resulted in a number of dead spots (deep fading points), UWB yielded none. This means the UWB systems have an advantage over narrowband ones from this propagation a viewpoint for reducing the fading margins. |
