Abstract :
In this paper, invasive weed optimization was used to calculate the p hases of adaptive antenna arrays for the purpose of placing null in the interfering direction and placing maximum power pattern in the desired signal direction to the far-field pattern. IWO algorithm will be stated and computed for this problem. The design results obtained with IWO have been shown to comfortably beat those obtained with PSO.
