Abstract: In this paper, a special optimization technique called Invasive weed optimization (IWO) has been initiated to synthesize linear variety of antenna arrays. IWO is applied to optimize amplitude excitations for performance improvement such as a reduced level of side lobes as well as control of null. A design example is considered and the amplitude weights are optimized with and without considering a specific beam width. In comparison with the conventional linear array antenna radiation pattern, this approach yields diminished levels of side lobe coupled with nulls positions in specific lines of choice. Keywords:
