Synthesis of Linear Antenna Array Using Firefly Algorithm

چکیده
Antenna array is the most important aspect to improve the communication process. The objective of this paper are to minimize the maximum side lobe level (SLL) and perform null steering for linear antenna arrays by controlling different parameters of the array elements (phase, position and amplitude). The Nature inspired optimization methods like Taguchi’s Optimization Method (TM), Self-Adaptive Differential Evolution (SADE), Firefly algorithm (FA) are the centre of attention in range of optimization problems. In this paper, phase excitation of array element is controlled by addressing FA to solve the problem of linear antenna array. Our results are also compared with TM and SADE which clearly indicates that firefly algorithm provides considerable enhancements than existing met-heuristic algorithm for desired shaped pattern. The effectiveness of FA for linear antenna array is exposed by means of numerical results.
