High frequency multimode feed, and antenna comprising such a feed

摘要

multimode microwave source, broad band, formed by a cavity (12), forming modeur, excited in the fundamental mode by a group of feed guides (9 / 10, 90, 100).section (17) comprising a barrier extending between the input (p) of the cavity, and the excitation level (db) of a hybrid mode for the low frequencies of the band.;application of radar technology in the source space, telecommunications antennas.
