Title
(EN) A DIRECTIONAL ANTENNA WITH A VARIABLE BEAM DIRECTION
(FR) ANTENNE DIRECTIVE À DIRECTION DE FAISCEAU VARIABLE
Abstract
(EN) Described herein is a source for a directional antenna. Also described are a directional antenna and a method of designing an antenna. In one aspect, the present disclosure provides a source with spatially substantially uniform phase. The source includes an emitter or receiver and a delay compensator being positioned in a near-field region of the emitter or receiver. In a second aspect, the present disclosure provides a directional antenna including a source and a pair of directional metasurfaces, both directional metasurfaces being positioned in a near-field region of the source.
(FR) L'invention concerne une source destinée à une antenne directionnelle. L'invention concerne également une antenne directionnelle et un procédé de conception d'une antenne. Selon l'un de ses aspects, la présente invention concerne une source ayant une phase sensiblement uniforme spatialement. La source comprend un émetteur ou un récepteur et un compensateur de retard étant positionné dans une région de champ proche de l'émetteur ou du récepteur. Selon un second aspect, la présente invention concerne une antenne directionnelle comprenant une source et une paire de métasurfaces directionnelles, les deux métasurfaces directionnelles étant positionnées dans une région de champ proche de la source.
