A directional multiple-polarization wide band antenna array working in a selected frequency band and including a plurality of N individual sensors of convoluted spiral type complementing a number of strands arranged according to a structure making it possible to obtain for obtaining a given azimuth coverage, each of the N sensors including a reflecting plane attached to the antenna by an insulating spacer E, matching cells suited to the working frequency band of said array, and separate output channels (5) and (7) for the vertically-polarized signals and for the horizontally-polarized signals. The antenna array also including a device suitable for executing a direction-finding algorithm that uses the amplitude and the phase of said signals and is matched to the configuration of the array. |
