GA optimized thinned hexagonal arrays for aatellite applications

In this paper the optimization of a transmitting array for satellite applications has been considered. Resorting to GA more than 30% of the initial elements can be switched off satisfying the technical requirements. The optimized configuration permits to drastically reduce the cost of the array and to improve the C/I level with respect to the initial fully populated array. Having all the active elements fed with the same amplitude, the HPA can be used in the most efficient way. Further improvements can be achieved by refining the cost function, and optimizing the element factor.
