ABSTRACT:
A monopulse feeder for transmission and/or reception of two separate frequency bands, the X and Ka bands, comprises a mouth section (8) and a wave guide section (9) connected to comparator circuits (5 and 6, respectively) for each frequency band. The mouth section is formed with two rectangular pairs of openings (81a, 81b and 82a, 82b, respectively) of which one (82a, 82b) is of smaller dimensions than the other (81a, 81b), and is placed between the openings of the second pair (81a, 81b). The feeder is placed at the inner focal point of a two-band Cassegrain reflector system.
