Horn antenna for transmission of microwaves comprising a conical horn (2), for directional transmission and reception of microwaves, and at the center of the horn's narrowest part, a transition piece (3) separating a wave guide from the environment. The transition piece (3) is tapered and is characterized by its tapering part (3a) being arranged so as to operate outside a normally fluid- filled circular space (4) between the horn (2) and the transition piece (3), so that the fluid in the space (4) does not affect the transmission of microwaves through the transition piece (3).
L'invention concerne une antenne de transmission d'hyperfréquences comprenant un cornet conique (2) destiné à l'émission et à la réception d'hyperfréquences et, au centre de la partie la plus proche du cornet, un élément de transition (3) séparant un guide d'onde de l'environnement. L'élément de transition (3) est effilé et caractérisé en ce que sa partie effilée (3a) est conçue pour fonctionner à l'extérieur d'un espace circulaire (4) normalement rempli de fluide et situé entre le cornet (2) et l'élément de transition (3) de telle façon que le fluide contenu dans l'espace (4) n'affecte pas l'émission d'hyperfréquences à travers l'élément de transition (3).
