Title (EN) REACTIVE COUPLING ANTENNA COMPRISING TWO RADIATING ELEMENTS
(FR) ANTENNE A COUPLAGE REACTIF COMPORTANT DEUX ELEMENTS RAYONNANTS
Abstract: front page image
(EN)The invention relates to a printed antenna comprising two planar radiating elements (25, 45) which are more or less stacked on top of each other. A first reactive coupling (5, 15) layout can excite one of the radiating elements (25, 45), said first reactive coupling layout comprising at least one feed line (6, 7) and a conductive ground plane (15) which is equipped with at least one coupling slot (16, 17). Moreover, the antenna comprises a second reactive coupling (25, 35) layout which can excite the other radiating element. The invention is characterised in that the radiating elements (25, 45) are provided with surface areas that are sufficiently similar so that the first reactive coupling layout produces a simultaneous coupling of the two radiating elements (25, 45).
(FR)L'invention concerne une antenne imprimée comprenant deux éléments rayonnants (25, 45) de forme planaire sensiblement superposés, un premier aménagement de couplage réactif (5, 15) apte a exciter un des éléments rayonnants (25, 45), ce premier aménagement de couplage réactif comprenant au moins une ligne d'alimentation (6, 7) et un plan conducteur de masse (15) muni d'au moins une fente de couplage (16, 17), l'antenne comprenant en outre un second aménagement de couplage réactif (25, 35) apte a exciter l'autre des éléments rayonnants, caractérise en ce que les éléments rayonnants (25, 45) ont des superficies dont les valeurs sont suffisamment proches pour que le premier aménagement de couplage réactif produise un couplage simultané des deux éléments rayonnants (25, 45).
