L'utilisation d'antennes hautement directionnelles est l'une des principales nécessités de toute installation de communication longue distance ou par satellite. Dans les systèmes de communication par satellite, les sources d'interférence persistent en raison de l'utilisation de plusieurs satellites et de signaux terrestres, ce qui peut dégrader les performances du système satellitaire et de la station de base. Il est donc nécessaire de disposer d'antennes directives avec un niveau de lobes latéraux (SLL) exceptionnellement bas pour atténuer les interférences provenant de sources non désirées. L'objectif principal de ce livre est de présenter des approches innovantes de la conception d'antennes réseau visant à améliorer les performances en termes de dimensions, de largeur de faisceau à mi-puissance (HPBW) et de SLL. Ces méthodes impliquent l'utilisation de réseaux avec des éléments soigneusement espacés ou pondérés, ajustant ainsi le diagramme de faisceau désiré du réseau, en conjonction avec l'utilisation d'antennes à éléments spécialisés.
