Abstract

In recent years, printed reflectarray (RA) have become more and more popular, because of their well-known advantages with respect to traditional parabolic reflectors. Their design could however be quite expensive from a computational point of view, since it requires the fulfillment of several constraints, that could be contrasting each other, and the management of many degrees of freedom, that are necessary to satisfy the design specifications. As the number of (geometrical) parameters to optimize in order to obtain the required radiating characteristics increases, their management can no longer be performed “by hand” and the use of a global optimization tool becomes almost mandatory. Here, one of the meta-PSO (MPSO) has been applied to the optimization of a realistic structure, the dual layer reflectarray antenna with innovative radiating elements introduced for use in the base station of the WISPERS Project (Wireless Infomobility System for ultra-light Platforms for Emergency Radio Services), which deals with emergency infomobility services based on an innovative Unmanned Air Vehicle (UAV).
