Linear annular antennas array design by evolutionary algorithms: A comparative study

This paper exposes a comparative study that was made between the adaptive particle swarm optimization (APSO) and hybrid model genetical optimizer approaches (GSO) for synthesis of 1-D equally spaced annular ring antenna arrays both TM11 TM12 modes. The uniform is designed as mono objective problem. employed techniques are compared in terms convergence rate side lobes level reduction. Several original numerical results provided to demonstrate performance proposed techniques. reveal suggested array approach using outperforms optimi zation reduction rate.
