Title
(EN) MULTIBAND ANTENNA STRUCTURE
(FR) STRUCTURE D'ANTENNE MULTIBANDE
Abstract
(EN)
A multiband antenna structure having an open rectangular box shape is arraged to provide identical electrical lengths for all of its radiating elements notwithstanding that the physical dimensions of portions of the multiband antenna may not be identical. Advantageously, such a multiband antenna may be interleaved with a 5G antenna array having unequal spacing between the 5G antennas or having an offset between at least one of the rows and the columns. This may be achieved by incorporating a dielectric material in at least one radiating element, by forming a radiating element with a serpentine shape, by having a radiating element follow a chicane, by incorporating a reflector of a 5G array, or by employing capacitive coupling.
(FR)
L'invention concerne une structure d'antenne multibande ayant une forme de boîte rectangulaire ouverte qui est agencée pour fournir des longueurs électriques identiques pour tous les éléments rayonnants, indépendamment du fait que les dimensions physiques des parties de l'antenne multibande peuvent ne pas être identiques. De manière avantageuse, une telle antenne multibande peut être entrelacée avec un réseau d'antennes 5G ayant un espacement inégal entre les antennes 5G ou ayant un décalage entre au moins l'une des rangées et des colonnes. Ceci peut être obtenu en incorporant un matériau diélectrique dans au moins un élément rayonnant, en formant un élément rayonnant ayant une forme en serpentin, en ayant un élément rayonnant qui suit une chicane, en incorporant un réflecteur d'un réseau 5G, ou en employant un couplage capacitif.
