Title (EN) WIDEBAND DUAL-POLARIZED MONOPOLE ANTENNA ELEMENT
(FR) ÉLÉMENT D'ANTENNE UNIPOLAIRE À DOUBLE POLARISATION À LARGE BANDE
Abstract:
(EN) A wideband dual-polarized current loop antenna element is provided having a ground tower and an antenna circuit integrated, such as within a multi-layer circuit board configuration. The antenna circuit includes feed conductors and element conductors, each of which are capacitively coupled to a top ground plane of the ground tower. The feed conductors are coupled to receive signals from coaxial feed lines coupled to the respective antenna element and element conductors are coupled to receive signals from adjacent antenna elements, such as in an antenna array configuration. The antenna element can further include one or more frequency selective surface (FSS) layers disposed proximate to the top ground plane of the ground tower and the antenna circuit. The ground tower, antenna circuit and one or more FSS layers can be formed to provide a low-profile antenna element having wide broadband performance.
(FR) Cette invention concerne un élément d'antenne à boucle de courant à double polarisation à large bande, comprenant une tour de mise à la masse et un circuit d'antenne intégré, par exemple à l'intérieur d'une configuration de carte de circuit imprimé multicouche. Le circuit d'antenne comprend des conducteurs d'alimentation et des conducteurs d'élément, dont chacun est couplé de manière capacitive à un plan de masse supérieur de la tour de mise à la masse. Les conducteurs d'alimentation sont couplés pour recevoir des signaux provenant de lignes d'alimentation coaxiales couplées à l'élément d'antenne respectif et des conducteurs d'élément sont couplés pour recevoir des signaux provenant d'éléments d'antenne adjacents, tels que dans une configuration de réseau d'antennes. L'élément d'antenne peut en outre comprendre une ou plusieurs couches de surface sélective en fréquence (FSS) disposée(s) à proximité du plan de masse supérieur de la tour de mise à la masse et du circuit d'antenne. La tour de mise à la masse, le circuit d'antenne et une ou plusieurs couches de surface sélective en fréquence peuvent être façonnés de sorte à fournir un élément d'antenne à profil bas ayant une haute performance à large bande.
