Keywords:
Array Antenna, Chaotic Sequence, Side Lobe Level, Fruit Fly Optimization AlgorithmAbstract
The side lobe level reduction for linear antenna array in free space using a chaotic sequence enhanced FOA method (CFOA) is presented in this paper. The method is used to determine an optimum set of amplitude parameters of the array antenna that provide a radiation pattern with minimize side lobe level reduction. To show the versatility of the presented method, the numerical result of the CFOA is validated by comparing with results obtained using the FOA method, and the GA/Fminsearch method. The numerical results demonstrate that the CFOA is superior to the FOA method, and the GA/Fminsearch method in terms of convergence and accuracy ability of the results.
