Title (EN) BEAM SWITCHING USING COMMON AND DIFFERENTIAL MODES
(FR) RADIODÉTECTION À BASCULEMENT DE DIAGRAMME UTILISANT DES MODES COMMUNS ET DIFFÉRENTIELS
Abstract:
(EN) There is disclosed an antenna arrangement comprising at least first and second radiating elements, each provided with an associated RF switch. The associated RF switches are operable so as selectively to connect either the first or the second radiating element individually to an RF port such that the first or the second radiating element respectively operates in an unbalanced mode, or to connect the first and second radiating elements together to the RF port such that the first and second radiating elements operate together in a balanced mode. The first and second radiating elements are electrically connected to each other by a link connection when either the first radiating element or the second radiating element is operating in the unbalanced mode.
(FR) L'invention concerne un agencement d'antenne comprenant au moins des premier et second éléments rayonnants, chacun comportant un commutateur RF associé. Les commutateurs RF associés peuvent fonctionner de façon à connecter sélectivement le premier ou le second élément rayonnant individuellement à un port RF de telle sorte que le premier ou le second élément rayonnant fonctionne respectivement dans un mode déséquilibré, ou de façon à connecter les premier et second éléments rayonnants ensemble au port RF de telle sorte que les premier et second éléments rayonnants fonctionnent ensemble dans un mode équilibré. Les premier et second éléments rayonnants sont électriquement connectés l'un à l'autre par une connexion de liaison lorsque le premier élément rayonnant ou le second élément rayonnant fonctionne dans le mode déséquilibré.
