Optimal Design of Concentric Circular Antenna Array Using Particle Swarm Optimization with Constriction Factor Approach
In this paper the maximum sidelobe level (SLL) reductions without and with central element feeding in various designs of three-ring concentric circular antenna arrays (CCAA) are examined using Particle Swarm Optimization with Constriction Factor Approach (PSOCFA) to finally determine the global optimal CCAA design. Binary coded Genetic Algorithm (BGA) is also employed for comparative optimizati...
متن کاملDesign of Circular Antenna Array using Particle Swarm Optimization
A new technique is proposed for the design of circular antenna arrays using particle swarm optimization. The design problem has been formulated to achieve a desired beamwidth and sidelobe level. This is accomplished by jointly optimizing the excitation amplitude and phase. The results obtained show improvement over conventional linear programming method.
متن کاملDesign of Concentric Circular Antenna Array using Biogeography Based Optimization
Biogeography based optimization (BBO) is a novel stochastic force based on the science of biogeography. Biogeography is the schoolwork of geographical allotment of biological organisms. BBO make use of migration operator to share information between the problem solutions. The problem solutions are called as habitats and sharing of features is called migration. In this paper, BBO algorithm is de...
متن کاملParticle Swarm Optimization with Constriction Factor and Inertia Weight Approach Based Synthesis of Concentric Circular Antenna Array with Non-isotropic Elements
In this paper, an evolutionary optimization technique, Particle Swarm Optimization with Constriction Factor and Inertia Weight Approach (PSOCFIWA) is adopted for the complex synthesis of three-ring Concentric Circular Antenna Arrays (CCAA) with non-isotropic elements and without and with central element feeding. It is shown that by selection of a fitness function which controls more than one pa...
متن کاملDetermination of the Optimal Design of Three- Ring Concentric Circular Antenna Array Using Evolutionary Optimization Techniques
In this paper the optimal design for maximum sidelobe level (SLL) reduction of three-ring concentric circular antenna array (CCAA) is determined using a novel Particle Swarm Optimization (PSO) technique namely Craziness based Particle Swarm Optimization (CRPSO). Real coded Genetic Algorithm (RGA) is adopted for the comparative optimization. The present text assumes nonuniformly excited array an...
