DIRECTIONAL MULTIPLE-POLARISATION WIDE-BAND ANTENNA NETWORK

摘要

The invention relates to a directional multiple-polarisation wide-band antenna network operating in a selected frequency band, characterised in that it comprises at least the following members: N elementary sensors of the convoluted spiral type complementary to a plurality of yarns arranged into a structure for obtaining an azimuth cover of about 360° and depending on the carrier; each of the N sensors includes a reflecting plane (2) attached to the antenna by an insulation strut E; each of the N sensors includes adaptation cells adapted to an operational frequency band of said network; each of the N sensors includes separate output paths (5) and (7) for signals with vertical polarisation and signals with horizontal polarisation; a device adapted for executing a goniometry algorithm using the amplitude and the phase of said signals and adapted to the network configuration.
