Application of Ant Colony Optimization Algorithm to Pattern Synthesis of Uniform Circular Antenna Array

The radiation pattern of the antenna arrays is most important problem in communications technology. In this paper, the optimization of uniform circular antenna array is efficiently solved by ant colony optimization (ACO) Method. The proposed method of optimization is used to determine the suitable cost function which leads to achieve the maximum reduction in side lobe level and provide the maximum directivity towards the direction. To optimize the desired antenna array pattern also one parameter is considered to be optimized which is the angular position of each element.
