Abstract[English]
An apparatus and method for electronically steering an OAM beam carrying multiple OAM modes is presented. An OAM antenna apparatus includes a plurality of UCAs and a plurality of electromagnetic signal confining structures. Each UCA has a respective plurality of waveguide antenna elements collectively operable to emit a respective OAM beam component carrying one or more OAM mode. Waveguide antenna elements of a UCA are coupled to a respective feed structure via respective feed waveguides coupled to respective bottom ends of waveguide antenna elements. Each feed structure is configured to process signals in accordance with the one or more OAM modes associated with the corresponding UCA and in accordance with beamsteering parameters.[French]
L'invention concerne un appareil et un procédé de pilotage électronique d'un faisceau OAM transportant de multiples modes OAM. Un appareil d'antenne OAM comprend une pluralité d'UCA et une pluralité de structures de confinement de signal électromagnétique. Chaque UCA comprend une pluralité respective d'éléments d'antenne de guide d'ondes pouvant fonctionner collectivement pour émettre un composant de faisceau OAM respectif transportant un ou plusieurs modes OAM. Des éléments d'antenne de guide d'ondes d'un UCA sont couplés à une structure d'alimentation respective par l'intermédiaire de guides d'ondes d'alimentation respectifs couplés à des extrémités inférieures respectives d'éléments d'antenne de guide d'ondes. Chaque structure d'alimentation est configurée pour traiter des signaux en fonction du ou des modes OAM associés à l'UCA correspondant et conformément à des paramètres de direction de faisceau.
