Study of the optimum number of radiating elements for different portable devices operating in a MIMO system

In this paper it is presented a study of the optimum number of radiating elements in a MIMO array for different portable devices working in the 5.6 GHz band. The array configurations are formed using a Vivaldi antenna as radiating element. This study tries to clarify how many elements are possible to allocate in the different form factors to achieve the best possible effective diversity gain (EDG). Laptop, PDA and PCMCIA are the form factors that are used in this study.
