MIMO antenna configuration for Femtocell application

Recent advances in the development of mobile applications have led to a need for mobile broadband platforms which support the capacity that these applications require. An investigation of possible antenna configurations that would be compatible with MIMO systems suitable for femtocell applications is presented. A MIMO configuration of up to 6×2 antenna elements is modelled with the use of HFSS. Its performance is measured by means of the ideal-channel capacity increase it provides compared to a SISO architecture. The performance of the same MIMO configuration is then successfully modelled in Epsilon¿ (Roke´s own channel modelling tool) with the use of a non-ideal indoor model. The simulations show that with the proposed configuration, it is possible to achieve a two-fold capacity increase compared to a SISO architecture in both channel conditions.
