Modelling and analysis of a smart antenna system with sub-sector dynamic capacity enhancement for mobile telecommunication networks

This paper describes the modelling and analysis of a new smart antenna concept. The paper outlines the rational for the development of a dynamically reconfigurable smart antenna system without greatly increasing the complexity of the system. The subject smart antenna system is developed to offer good coverage and capacity using multiple beams throughout a cell sector and to be able to reconfigure the beam to provide enhanced coverage and maintain capacity in certain areas at reduced, but acceptable coverage throughout the rest of the cell sector of a mobile telecommunication network. The motivation behind the architecture and the methodology used is discussed and then modelling and analysis of the antenna system is presented.
