A phased array antenna (100) includes a substrate (104), and an array of dipole antenna elements (40) on the substrate (104). Each dipole antenna element (40) comprises a medial feed portion (42), and a pair of legs (44) extending outwardly therefrom, and adjacent legs (44) of adjacent dipole antenna elements (40) include respective spaced apart end portions (46). A respective impedance element is electrically connected between the spaced apart end portions (46) of adjacent legs (44) of adjacent dipole antenna elements (40) for providing increased capacitive coupling therebetween.

L'invention concerne une antenne (100) réseau à commande de phase comprenant un substrat (104) et un réseau d'éléments (40) d'antenne bipolaire sur le substrat (104). Chaque élément d'antenne (40) bipolaire comprend une partie d'alimentation médiale (42) et une paire de jambes (44) s'étendant à l'extérieur, des jambes (44) adjacentes des éléments d'antenne bipolaire adjacents (40) comprenant des parties (46) d'extrémité espacées correspondantes. Un élément d'impédance correspondant est relié de manière électrique entre les parties (46) d'extrémité espacées des jambes adjacentes (44) des éléments d'antenne (40) bipolaires adjacents, ce qui permet un meilleur couplage capacitif entre eux.
