ABSTRACT:
A multifrequency radiating device comprising at least one radiating element (11) of a first type and at least one radiating element (12) of a second type, the elements being associated on a common surface (10) in order to constitute an array antenna. The radiating elements of the first type (16) are elements of the microstrip type and the elements of the second type (19, 20) are elements of the wire type, the radiating elements of the first type (16) acting in a first frequency range and the radiating elements of the second type (19, 20) acting in a second frequency range. The invention is particularly applicable to microwave antennas.
