UWB radio has proved itself a suitable candidate for its low power and low cost design. How- ever, very low transmitted power in UWB systems limits the applications to short range or to moderate data rate. Therefore, it is crucial to find some solution that will make the best possible use of radiated and received power, for the feasibility and future commercial success of UWB communication systems. In this context, research is carried out and MIMO has been found one of the best solutions. MIMO technique in UWB systems will improve link robustness of UWB or data rate. But some challenges arise in designing of the MIMO antenna systems for UWB applications. These challenges include the reduction of the mutual coupling and the correlation be- tween the elements of the antenna systems. In this article, antenna systems proposed in the literature as well as by authors have been discussed. Some techniques have been presented to face these challenges. Finally, proposed UWB-MIMO antenna systems in the frequency band of 3.1 – 10.6 GHz are efficient in terms of diversity, radiations, size, etc.
