Linear Antenna Array Synthesis with Invasive Weed Optimization Algorithm

Linear antenna array design is one of the most important electromagnetic optimization problems of current interest. This article describes the application of a recently developed metaheuristic algorithm, known as the invasive weed optimization (IWO), to optimize the spacing between the elements of the linear array to produce a radiation pattern with minimum side lobe level and null placement control. The results of the IWO algorithm have been shown to meet or beat the results obtained using other state-of-the-art metaheuristics like the genetic algorithm (GA), particle swarm optimization (PSO), memetic algorithms (MA), and tabu search (TS) in a statistically meaningful way.
