Abstract (en)
[origin: EP0315141A1] Arrangement for exciting a circularly polarised waveguide via a flat antenna, this waveguide (10) being a straight hollow guide closed at one end (12), this antenna being excited by at least two coaxial drives (13, 14) supplied in phase quadrature by a circuit comprising a hybrid coupler (15), and consists of a flat metal radiating pattern (11) laid on the surface of an insulating substrate (18) closing the guide (10) perpendicularly to its axis of symmetry. <??>Application in particular to the field of microwaves. <IMAGE>
