Title (EN) FRACTAL-RECTANGULAR REACTIVE IMPEDANCE SURFACE FOR ANTENNA MINIATURIZATION
(FR) SURFACE D'IMPÉDANCE RÉACTIVE RECTANGULAIRE FRACTALE POUR MINIATURISATION D'ANTENNE
Abstract: front page image
(EN)Various examples are provided that are related to fractal-based reactive impedance surfaces. These surfaces allow for miniaturization of antennas. In one example, a fractal rectangular reactive impedance surface (FR-RIS) includes a plurality of fractal rectangular (FR) patches having an outer edge defined by a fractal rectangular pattern that is repeated along each side of inner FR patches of the plurality of FR patches. The fractal rectangular pattern of a FR patch matches with the fractal rectangular pattern of an adjacent FR patch. An antenna can include a planar antenna disposed over the FR-RIS.
(FR)Selon divers exemples, l'invention concerne des surfaces d'impédance réactive à base fractale. Ces surfaces permettent une miniaturisation d'antennes. Dans un exemple, une surface d'impédance réactive rectangulaire fractale (FR-RIS) comprend une pluralité de plaques rectangulaires fractales (FR) ayant un bord extérieur délimité par un motif rectangulaire fractal qui est répété le long de chaque côté de plaques FR intérieures de la pluralité de plaques FR. Le motif rectangulaire fractal d'une plaque FR correspond au motif rectangulaire fractal d'une plaque FR adjacente. Une antenne peut comprendre une antenne plane disposée sur la FR-RIS.
