The Inverse Fast Fourier technique (IFFT) combined with Artificial Bees Colony (ABC) and Modified Particle Swarm Optimization (MPSO) is used for the synthesis of thinned mutually coupled linear array with uniform element spacing. Coupling effect has been taken into account via induced EMF method and used to calculate the induced current on each element. Proposed technique is employed to thin the array optimally to yield a minimum possible SLL and low return loss (RL). Performances of both the algorithms are compared to show the effectiveness of each optimizer. Introduction of Inverse Fast Fourier transform to calculate the array factor reduces the computation time significantly. The effectiveness of the proposed technique is demonstrated for 100- element linear array and results are compared with that of a fully populated array.
