New Antenna Design Concept for Future Generation Wireless Communication Systems

Design methodologies for antenna arrays of future generation mobile system are required to provide solutions able to maximize the data-rate performance of the system. However, current design methodologies are focused on the maximization of pattern-related performance metrics in order to indirectly provide solutions with optimal capacity performance. This work is aimed at showing that there is not a direct or indirect relation between pattern performance and capacity performance, since the latter strongly depends on the surrounding scenario. As a consequence, new design methodologies should take into consideration the propagation scenario instead of pattern performance metrics in the design process. In order to provide a preliminarily proof of this concept an illustrative numerical example is shown.
