Title (EN) ANTENNA DEVICE AND METHOD FOR TRANSMITTING AND RECEIVING RF WAVES
(FR) DISPOSITIF D'ANTENNE D'EMISSION ET DE RECEPTION D'ONDES DE RADIOFREQUENCE
Abstract: front page image
(EN)An antenna device for transmitting and/or receiving RF radiation, installable in and connectable to a radio communication device, and comprising an antenna structure (5-9, 11, 13, 35, 61) switchable between a plurality of antenna configuration states, each of which is distinguished by a set of radiation parameters, such as resonance frequency, input impedance, bandwidth, radiation pattern, gain, polarization, and near-field pattern, and a switching device (4, 36, 60) for selectively switching said antenna structure between said plurality of antenna configuration states, wherein each of said plurality of antenna configuration states being adapted for use of the antenna device in said radio communication device in a respective predefined physical operation environment (TP, FS, WP, PP), is disclosed.
(FR)L'invention concerne un dispositif d'antenne d'émission et/ou de réception de rayonnements de radiofréquence, que l'on peut installer et connecter à un appareil de communication radio. Ce dispositif comporte une structure d'antenne (5-9, 11, 13, 35, 61) commutable entre plusieurs modes de configuration d'antenne, chacun d'eux se distinguant par un ensemble de paramètres de rayonnements, comme la fréquence de résonance, l'impédance d'entrée, la largeur de bande, le motif de radiation, le gain, la polarisation, et le motif du champ voisin, et un appareil de commutation (4, 36, 60) servant à commuter sélectivement ladite structure d'antenne entre les divers modes de configuration d'antenne, dans lesquels chacun desdits modes de configuration d'antenne étant adapté pour l'utilisation du dispositif d'antenne dans ledit appareil de communication radio, au sein d'un environnement respectif d'opération physique prédéfini (TP, FS, WP, PP).
