Abstract: The combination of ultra-wideband (UWB) spectrum with Multiple-Input Multiple-Output (MIMO) system techniques show great promise for developing very high bandwidth wireless personal area networks (WPANs). While these networks have been explored in theory, there is little literature regarding the practical limitations of this technology. Speci cally, the mutual coupling between the antennas in the system is usually ignored. This thesis quanti es the e ects of mutual coupling in MIMO UWB systems. A variety of antenna geometries and spacings were simulated. Several scenarios in a typical WPAN environment were simulated using electromagnetic ray tracing (ERT) techniques. These results were validated using network analyzer channel measurements. These results show mutual coupling has a signi cant impact on channel capacity. Furthermore, in most scenarios, mutual coupling can actually improve the channel capacity by decorrelating adjacent spatial channels. Knowledge of this potential bene t of mutual coupling in MIMO-UWB systems will allow future WPAN designers to develop systems using small, multi-antenna devices with very high capacities.
