Title (EN) MICROWAVE ANTENNAS
(FR) ANTENNES HYPERFREQUENCE
Abstract:
(EN) A microwave antenna (10) is formed from a stack of generally planar elements (14-22) forming an array of horns (12) communicating with waveguides (38). The generally planar elements (14-22) are of metallised plastics. Each of these elements (14-22) has a given overall thickness which is constituted by a membrane of relatively small thickness formed (typically by vacuum forming) into a corrugated shape.
(FR) Selon l'invention, on forme une antenne hyperfréquence (10) à partir d'une pile d'éléments (14-22) généralement plans formant un réseau d'éléments en forme de cornets communiquant avec les guides d'ondes (38). Ces éléments (14-22) sont en plastique métallisé et présentent chacun une épaisseur globale constituée par une membrane d'épaisseur relativement faible, dotée (généralement par formation sous vide) d'une configuration ondulée.
