UWB wireless interconnect scheme for communicating devices within small conducting enclosure

This paper presents a novel concept which proposes the use of an ultra-wide bandwidth (UWB) ultra small scale wireless interconnect scheme for use within a electrically small enclosure. Such ultra small environments (size ≤ 10 wavelengths) are topologically much more complex, being more cluttered, than typical indoor environments (size ≥ 10 wavelengths). The concept is presented using an aluminium tower case as a model environment where 8 PCI cards are located inside. The research aims to determine the optimum channel interconnects communication via wireless and to establish design rules for this type of environment. The investigation is based on the analysis of the behaviour of box modes within a conducting enclosure and the effective communications bandwidth for UWB systems. From these general considerations the paper presents theoretical and experimental results from which are derived the communications metrics measured within an enclosure.
