| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Ultra wideband (UWB) propagation was measured and characterized within spacecrafts, with a view to partly replacing onboard data buses with wireless connections. Spatial distributions of UWB and narrowband propagation in frequency (from 3.1 to 10.6 GHz) and time domains were measured with a microwave vector network analyzer. While narrowband resulted in a number of dead spots (deep fading points) within the conductive enclosures, UWB yielded none. This implies the UWB systems have an advantage over narrowband ones from a viewpoint of reducing fading margins. It was also found that delay spreads can be suppressed by partially paneling a radio absorber on the inner surfaces to facilitate high data rate transmission. | |
