    • Design of single shaped reflector antennas for synthesis of shaped contour beams using genetic algorithms 

      Vall-Llossera Ferran, Mercedes Magdalena; Rius Casals, Juan Manuel; Duffo Ubeda, Núria; Cardama Aznar, Ángel (JOHN WILEY & SONS INC, 2000-12-31)
      Article
      Accés obert
      A genetic algorithm (GA) has been developed for designing single-shaped reflector antennas for the synthesis of shaped contour beams. The graphical processing technique is used in order to obtain the antenna radiation ...
