An integer genetic algorithm for optimal clustering in phased array antenna

A subarraying technique based on a novel genetic algorithm (GA) whose operators have been suitably customized in order to deal with integer variables is presented in this paper. The method is aimed to prevent the generation of high-level quantization lobes in the scanned radiation pattern by properly combining a given number of clusters selected from an arbitrarily defined alphabet of tiles of various shapes. A representative numerical result is reported in order to show advantages and drawbacks of the proposed methodology.
