Title
(EN) DIFFERENTIAL FED DUAL POLARIZED TIGHTLY COUPLED DIELECTRIC CAVITY RADIATOR FOR ELECTRONICALLY SCANNED ARRAY APPLICATIONS
(FR) ÉLÉMENT RAYONNANT À CAVITÉ DIÉLECTRIQUE À COUPLAGE SERRÉ À DOUBLE POLARISATION ET À ALIMENTATION DIFFÉRENTIELLE POUR APPLICATIONS DE RÉSEAU À BALAYAGE ÉLECTRONIQUE
Abstract
(EN)
An antenna element includes a balun configured to convert an unbalanced signal to a balanced signal and having an input, a first output, and a second output. The antenna element further includes a feed layer having a first feed coupled to the first output of the balun, a second feed coupled to the second output of the balun, a first ridge coupled to the first feed, a second ridge coupled to the second feed, and a center post.
(FR)
L'invention porte sur un élément d'antenne qui comprend un symétriseur configuré pour convertir un signal non équilibré en un signal équilibré et ayant une entrée, une première sortie et une seconde sortie. L'élément d'antenne comprend en outre une couche d'alimentation ayant une première alimentation couplée à la première sortie du symétriseur, une seconde alimentation couplée à la seconde sortie du symétriseur, une première nervure couplée à la première alimentation, une seconde nervure couplée à la seconde alimentation, et une tige centrale.
