In this work, classical real–valued particle swarm optimization (PSO) schemes have been modified by introducing a selection operator commonly used in genetic algorithms (GA), the tournament selection strategy (TS). The usefulness and limitations of the hybridized approach have been analyzed by comparing it with some well–known PSO classical schemes, when both are applied to planar array synthesis using complex weights. The preliminary statistical results obtained demonstrate the usefulness of the hybrid approach. For those purposes, the synthesis of the complex element weights to best meet certain far–field radiation pattern restrictions given in terms of 3D–masks has been considered as the canonical problem. Finally, further representative synthesis results for a planar array to be considered as a 60 degrees sector antenna for local multipoint distribution systems (LMDS) are also included.
