Abstract

Antena radioeléctrica, especialmente para artefacto espacial, que incluye un reflector (20) y medios de soporte (19) de este reflector, incluyendo el reflector un casco (22) capaz de reflejar las ondas radioeléctricas y una estructura posterior rígida (28) soportada por los medios de soporte y unida al casco (22) mediante perfiles angulares de desacoplamiento (24) repartidos alrededor de un eje del casco (22) e incluyendo, cada uno, una primera base (32) fijada al casco (22) del reflector, con la antena caracterizada porque cada uno de dichos perfiles angulares de desacoplamiento (24) incluye una laminilla metálica flexible (34) o una segunda base fijada a la estructura posterior rígida (28) y una lámina metálica central (30) que une dicha primera base (32) a dicha laminilla metálica flexible o a dicha segunda base y capaz de amortiguar una componente transversal de vibraciones del casco (22)y en por lo menos uno de sus extremos, una capa de material elástico (38) capaz de amortiguar por lo menos una componente axial de vibraciones del casco (22), con dicha capa de material elástico (38) interpuesta entre dicha primera base (32) y el casco (22), o entre dicha laminilla metálica flexible o dicha segunda base y dicha estructura posterior rígida (28).
