A multilayered slot-coupled antenna device employs a push-pull arrangement of at least two slot-feedline pairs, whereby the feed lines are driven from a common signal source and configured such that changes in antenna centre- frequency and input impedance due to layer offsets are largely compensated.
L'invention concerne un dispositif d'antennes couplées à des fentes multicouches, faisant appel à un agencement pousser-tirer d'au moins deux paires de conduites d'alimentation, les conduites d'alimentation étant issues d'une source de signal commune et configurées de sorte que les changements au niveau de la fréquence centrale de l'antenne et de l'impédance d'entrée, provoqués par des décalages de couche, sont largement compensés.
