Abstract (en)

The antenna has a layer arrangement (30) with three metallized layers (32, 34, 36) that are arranged parallel to each other and separated from each other by dielectric sheets (38, 40). Two of the layers comprise a two dimensions periodical metallization structure, and the third layer comprises a continuous metallization region. A stimulation structure (50) is arranged above one of the layers for stimulating a leakage wave mode in the arrangement with an operating frequency of the antenna. The arrangement has a regular N-corner shape or a circular shape as edge limiting characteristics.

Abstract (de)

Eine Leckwellenantenne (10) umfasst eine Lagenanordnung (30) mit einer ersten, zweiten und dritten metallisierten Lage (32, 34, 36), die übereinander und parallel zueinander angeordnet sind und die durch zwei dielektrische Schichten (38, 40) voneinander getrennt sind, wobei die erste metallisierte Lage (32) eine erste, zwei-dimensional periodische Metallisierungsstruktur aufweist, wobei die zweite metallisierte Lage (34) eine zweite, zweidimensional periodische Metallisierungsstruktur aufweist, und wobei die dritte metallisierte Lage (36) einen durchgehenden Metallisierungsbereich aufweist, und eine Anregungsstruktur (50) oberhalb der ersten metallisierten Lage (32) zum Anregen eines Leckwellenmodus in der Lagenanordnung (30) bei einer Arbeitsfrequenz f 0 der Leckwellenantenne, wobei die Lagenanordnung (30) als Randbegrenzungsverlauf eine Form eines regelmäßigen N-Ecks mit N ‰¥ 8 ( N ˆˆ Z) oder eine Kreisform aufweist.
