Synthesis of Thinned Concentric Ring Array with Dipole Radiators Using Firefly Algorithm
2014
IOSR Journal of Electronics and Communication Engineering
Preserved Fulltext
The application of new metaheuristic approach, Firefly algorithm, for the thinning of large multiple Concentric Circular dipole arrays is presented. A nine-ring Uniform Circular antenna array with central element feeding is considered. To analyze the effect of thinning, optimization is carried out with and without pre fixing the percentage value of thinning. The performance of the array in terms of sidelobe level and beam width is discussed in four cases. The numerically simulated patterns are
