Optimization of circular antenna arrays using particle swarm optimization

Abstract

Considering that a single antenna is insufficient in most cases it is seen that antenna arrays are very important. Very effective results can be obtained by changing variables such as geometric configurations of antenna arrays, phases and amplitudes of array elements. In this study, particle swarm optimization which is known to maintain considerably correct results for swarms and arrays is used to increase the efficiency of the circular antenna arrays. Particle swarm optimization, which is called inductive optimization, going from particle to swarm, and which gives successful results in swarm optimizations is preferred to suppress the sidelobes of the circular antenna arrays.
