Title
(EN) MULTI MODE ANTENNA SYSTEM
(FR) SYSTÈME D'ANTENNES MULTIMODES
Abstract
(EN)
An antenna system comprising a first antenna element, a second antenna element, the first and second elements defining at least in part a slot element, an active switching network in communication with one or both of the first and second antenna elements, the switching network operable to cause the antenna system to resonate in each of two modes: a first mode wherein the first element resonates at a first set of frequencies, and the first element and a second element resonate together at a second set of frequencies; and a second mode wherein the first element resonates at the first set of frequencies, and the slot element resonates at a third set of frequencies.
(FR)
L'invention porte: sur un système d'antennes comprenant un premier élément d'antenne et un deuxième élément d'antenne délimitant au moins en partie un élément constitué d'une fente; et sur un réseau actif de commutation en communication avec une antenne ou les deux et amenant le système à résonner dans un premier ou un deuxième mode. Dans le premier mode, le premier élément résonne à un premier ensemble de fréquences et le premier et le deuxième élément résonnent ensemble à un deuxième ensemble de fréquences; et dans le deuxième mode, le premier élément résonne à un premier ensemble de fréquences et l'élément fente résonne à un troisième ensemble de fréquences.
