Measurement of Ultra Wideband Channel Sounding Using Vector Network Analyzer
Abstract: This paper analyzes
the measurement of ultra wideband (UWB) noise channels in different indoor environments.
All measurements are done using a vector network analyzer (VNA) which allows us
to measure the noise channel transfer functions. We find that the noise power
of the system is decreased by increasing the intermediate frequency (IF)
bandwidth which leads to an increase in time taken to perform measurements of
the channels. The environmental noise power been measured and find that it
decreased when enclosed in a Faraday cage (steel shed), within an intense
multipath measurement environment. Also, the Environmental noise decreases
slightly by using the LPDA antenna compared to using the Teardrop and Horn
antennas. Our results show that the Horn antenna is less suitable for UWB
channel measurements compared to the LPDA directional antennas because of lower
S11 (Return Loss) values. While for omnidirectional antennas, the Teardrop
antenna is much more suitable than the monocone antennas for UWB measurements
(due to lower S11 values) and decreases the Environmental noise power. As
secondary application, we show how a frequency detection device can be used to
re-adjust a maladjusted frequency selection on a remote controller for a garage
door, in presence of environmental noise power.
