This thesis presents a statistical wireless channel characterization for near-ground antennas in both indoor and outdoor environments based on narrowband and wideband measurements. We took measurements in both line of sight and non-line of sight regions. For the narrowband case, we measured indoors, in the 900 MHz and 2.4 GHz unlicensed bands. Results for the narrowband near-ground indoor channels include channel power versus frequency responses and corresponding distributions of relative received power over the measured bands. For the wideband near-ground indoor and outdoor channels, measured in the 5 GHz band, channel impulse response statistics, including delay spreads and coherence bandwidth, were obtained from power delay profiles. Wideband channel models were developed from the measurements, and these models include statistical characterizations of Markov tap persistence process parameters, tap energies, tap fading amplitudes, and correlations among taps. The wideband channel models were developed for a 10 MHz channel bandwidth. As expected, the near-ground channels yield more dispersion and deeper fading than their counterparts with elevated antennas.
