Краткое описание

Comparative study of two evolutionary algorithms namely backtracking search algorithm (BSA) and firefly algorithm (FA) has been described in this paper for synthesis of cosecant squared radiation pattern in linear antenna array. BSA and FA have been used with the inverse fast Fourier transform (IFFT) to reduce the computational time significantly. Performance of the above algorithms for synthesis of shaped beam pattern are compared here in terms of different antenna parameters like side lobe level, maximum reflection coefficient (S11) in dB, ripple as well as statistical parameters such as global best fitness value, worst fitness value, mean and standard deviation. To obtain the cosecant squared pattern, voltage excitation and the static phase shift of the linear array elements are taken as the optimizing parameters and BSA and FA is used as the optimizing algorithms. In addition to it, obtained results from simulation of both the optimization algorithm on MATLAB is also validated by results obtained from FEKO analysis. Mutual coupling has been considered between the parallel dipole antennas. Work is demonstrated by twenty four element linear array of parallel dipole antennas for synthesis of shaped beam pattern.
