Abstract:

For overcoming the problem of slow convergence speed and local optimum in handling the high-dimension complex problem by the Invasive Weed Optimization Algorithm(IWO), a hybrid Invasive Weed Optimization Algorithm(HIWO) is proposed by integrating the Simplified Quadratic Interpolation(SQI) method into the IWO. The SQI Method is integrated in the IWO as a local search operator to enhance the performance of the algorithm, improve the convergence speed and computation accuracy. Simulation results for different design requirements show that the proposed algorithm performs better than other existing algorithms in the problem of shaped beam synthesis of array antennas.

Key words: array antennas, shaped beam antennas, invasive weed optimization, simplified quadratic interpolation
