1. Corrugated passive radiofrequency device including a core comprising at least one internal face delimiting a channel for filtering and guiding waves, the said at least one internal face of the channel comprising a plurality of cavities or annular grooves, each cavity or each annular groove being formed by substantially parallel adjacent walls in order to filter the waves passing through the channel,
wherein the radiofrequency device is a horn-type antenna,
wherein said adjacent walls are inclined with respect to the central axis of the channel, and
wherein said adjacent walls forming the annular grooves are inclined at a second angle of between 30° and 80° with respect to an internal surface of the antenna.
