Abstract :
Genetic algorithm (GA) is used to design a type of sector array antenna for smart antenna system front end. The sector array antenna is mainly applied to the base station of TD-SCDMA. Firstly, to meet the demand of smart antenna system sector coverage mode (namely broadcast mode), the arrays configuration and element weight arc obtained by the global-search GA. Secondly, element weight is optimized to simulate the tracking mode (namely working mode) by GA. The sector antenna array of practical smart antenna system is analyzed, which is meaningful for the smart antenna technology.
