Title (EN) WIDEBAND DIPOLE ARRAY ANTENNA ELEMENT
(FR) ELEMENT D'ANTENNE EN RESEAU DE DIPOLES A BANDE LARGE
Abstract: front page image
(EN)A linearly polarized wideband dipole array antenna element (100) capable of operating up to approximately 5:1 to 10:1 or more in bandwidth for receive and/or transmit wireless communications applications is provided. The antenna element includes multiple large-diameter cylindrical tubular dipole elements (100) that are very closely spaced. The internally fed dipoles (100) have flat end caps (120) and the close spacing increases the mutual coupling between dipoles to improve the low frequency performance.
(FR)L'invention concerne un élément d'antenne en réseau de dipôles à bande large et à polarisation linéaire capable de fonctionner jusqu'à environ 5 : 1 à 10 : 1 ou plus en largeur de bande afin de recevoir et/ou transmettre des applications de communication sans fil. Cet élément d'antenne comprend plusieurs éléments de dipôles tubulaires cylindriques de large diamètre qui sont très étroitement espacés. Les dipôles à alimentation interne présentent des extrémités plates et l'espacement étroit augmente le raccord mutuel entre les dipôles afin d'améliorer la performance à fréquence basse.
