Abstract
Ultra wideband (UWB) has the potential for high data rates, ranging and positioning.
A UWB communication system's design requires knowledge regarding the channel. This
thesis investigates the effect that different antenna orientations have on the wireless
channel; in an indoor office environment. Channel reciprocity, path loss, body shadowing
and spatial correlation are investigated for the frequency band 3.1 to 10.6 GHz. The
measurements are performed in the frequency domain. UWB channels are shown to be
highly reciprocal in all instances. Path loss versus distance was determined for line of
sight (LOS) and non-line of sight (NLOS) scenarios. Body shadowing is measured for an
average Caucasian male, and the root mean square (RMS) delay spread and received
power loss plotted spatially. The spatial correlation is investigated using a two
dimensional grid. A comparison between the horizontal and vertical polarization is
made.
