Abstract (en)
[origin: US2021288409A1] A monopole wire-plate antenna that is reconfigurable in a frequency range of operation, comprising:a ground plane (1);a capacitive roof (2);a probe feed (3), which is electrically insulated from the ground plane (1), and which extends between the ground plane (1) and the capacitive roof (2) so as to electrically feed the capacitive roof (2);at least one shorting wire (4), which is arranged to electrically connect the capacitive roof (2) to the ground plane (1), and which is coated in a magneto-dielectric material (5) having a complex magnetic permeability, which varies as a function of a static magnetic field applied to the magneto-dielectric material (5).
Abstract (fr)
Antenne fil-plaque monopolaire reconfigurable dans une gamme de fréquences de fonctionnement, comportant :- un plan de masse (1) ;- un toit capacitif (2) ;- une sonde d'alimentation (3), électriquement isolée du plan de masse (1), et s'étendant entre le plan de masse (1) et le toit capacitif (2) de manière à alimenter électriquement le toit capacitif (2) ;- au moins un fil de court-circuit (4), agencé pour connecter électriquement le toit capacitif (2) au plan de masse (1), et enrobé d'un matériau magnéto-diélectrique (5) présentant une perméabilité magnétique complexe, variable en fonction d'un champ magnétique statique appliqué au matériau magnéto-diélectrique (5).
