Abstract: The design of antenna arrays used in the recent technologies are expected to contain large number of antenna elements operating over a broad frequency range where the signals from each antenna element are combined and processed simultaneously providing high sensitivity with multiple beams providing a wide field of view. Array geometry is the main design aspect which influences the cost and performance of the system. The optimization techniques are needed to enhance the performance of the antenna array. The large bandwidth and number of broadband antenna elements makes the optimization of antenna array system difficult to achieve with the current array geometry optimization techniques. Such array geometry optimization techniques rely mainly on genetic algorithms and pattern search techniques. Here provides a study of the array geometry effects on the performance of broadband array system. Instead of controlled randomization and space tapering, the particle swarm optimization is used as the optimization technique which is an iterative based algorithm. This algorithm can provide a global best position for the antenna elements which gives improved performance.
