Title
(EN) SELECTIVELY DRIVEN ULTRA-WIDEBAND ANTENNA ARRAYS
(FR) RÉSEAUX D'ANTENNES À BANDE ULTRALARGE COMMANDÉS DE MANIÈRE SÉLECTIVE
Abstract
(EN)
A antenna array operable in an ultra-wide bandwidth, in which a ratio between a highest designed operating frequency and a lowest designed operating frequency exceeds 2: 1, includes antenna elements arranged in rows along a planar surface. The antenna elements have spacing between adjacent elements determined in accordance with a wavelength of the highest designed operating frequency. A feeding network is configured to feed different groups of antenna elements of the antenna array using signals in different frequency bands. An antenna element of the antenna array may be fed by a signal in one frequency band, by signals in more than one frequency band, or may not be fed at all.
(FR)
La présente invention concerne un réseau d'antennes fonctionnant dans une bande passante ultra-large, dans lequel un rapport entre la fréquence conçue de fonctionnement la plus élevée et la fréquence conçue de fonctionnement la plus basse est supérieur à 2 : 1, comprend des éléments d'antenne agencés en rangées le long d'une surface plane. Les éléments d'antenne ont un espacement entre des éléments adjacents déterminés en fonction d'une longueur d'onde de la fréquence de fonctionnement la plus élevée. Un réseau d'alimentation est conçu afin d'alimenter différents groupes d'éléments d'antenne du réseau d'antennes à l'aide de signaux dans différentes bandes de fréquences. Un élément d'antenne du réseau d'antennes peut être alimenté par un signal dans une bande de fréquence, par des signaux dans plus d'une bande de fréquence, ou peut ne pas du tout être alimenté.
