Title
(EN) ADJUSTABLE ANTENNA
(FR) ANTENNE RÉGLABLE
Abstract
(EN)
A device includes a compressible conductive element including a first end and a second end, and an adjustment element coupled to the compressible conductive element, the adjustment element configured to adjust the compressible conductive element to a state of compression between an uncompressed mode and a compressed mode. The compressible conductive element is configured to couple to a source of electrical current at the first end and to radiate electromagnetic energy from the second end.

La présente invention concerne un dispositif qui comprend un élément conducteur compressible comprenant une première extrémité et une seconde extrémité, et un élément de réglage accouplé à l'élément conducteur compressible. L'élément de réglage est conçu pour régler l'élément conducteur compressible sur un état de compression entre un mode non comprimé et un mode comprimé. L'élément conducteur compressible est conçu pour s'accoupler à une source de courant électrique sur la première extrémité et pour émettre un rayonnement électromagnétique à partir de la seconde extrémité.
