Abstract

L'invention concerne une antenne (10) pour un satellite spatial comprenant au moins : un guide d'ondes (20) ayant d'une extrémité (21) destinée à émettre ou à recevoir une onde électromagnétique, une structure piège à ondes de surface (30) solidaire de l'extrémité du guide d'ondes, ladite structure comprenant une surface (31) s'étendant transversalement par rapport au guide d'ondes à partir de laquelle font saillie des anneaux concentriques (32) autour du guide d'ondes, caractérisée en ce qu'elle comprend en outre une lentille diélectrique (60) fixée sur l'extrémité (21) du guide d'ondes, la lentille présentant une forme de révolution autour d'un axe (X) du guide d'ondes, le diamètre de la lentille étant croissant en s'éloignant de l'extrémité du guide d'ondes, et en ce que la lentille présente une permittivité diélectrique relative effective supérieure à 1 et inférieure ou égale à 5.The invention relates to an antenna (10) for a space satellite comprising at least: a waveguide (20) having at one end (21) for transmitting or receiving an electromagnetic wave, a surface wave trap structure (30) integral with the end of the waveguide, said structure comprising a surface (31) extending transversely with respect to the waveguide from which protrude concentric rings (32) around the waveguide. waves, characterized in that it further comprises a dielectric lens (60) fixed to the end (21) of the waveguide, the lens having a shape of revolution about an axis (X) of the waveguide. waves, the diameter of the lens increasing as the distance from the end of the waveguide increases, and in that the lens has an effective relative dielectric permittivity greater than 1 and less than or equal to 5.
