摘要：
This paper illustrate an efficient approach to enhance the directivity and minimize the side lobe level (SLL) of a non-uniform concentric circular antenna array (CCAA) considering the mutual coupling using a robust search algorithm called opposition based gravitational search algorithm (OGSA). Particle swarm optimization (PSO) and differential evolution (DE) optimization methods are also employed to compare the results obtained by using OGSA. An improved radiation characteristic with low SLL and high directivity considering the mutual coupling is achieved using an optimal current excitation weights and inter-element separation between the array elements of CCAA. The design examples of CCAA having sets of (4,6,8) and (1,4,6,8) elements are presented and their performances are studied in this paper.
