Description
Claims (4)
- Vorrichtung zum Abdecken der Apertur einer Antenne, die einen parabolischen Reflektor, einen Erreger und eine Abdeckung aus steifem Material aufweist, deren Außendurchmesser dem Durchmesser des Reflektors entspricht und die auf ihrer vom Reflektor wegweisenden Seite nach außen gewölbt ist, dadurch gekennzeichnet, daß die Abdeckung aus einem mit dem Reflektor (1) verbundenen Abschirmring (4) und aus einem denselben am freien Ende verschließenden, aus Kunststoff bestehenden Deckel (5) aufgebaut ist, der als flacher Kegel ausgeführt ist und dessen Wandung mit einer im rechten Winkel zur Achse (A) des Abschirmrings (4) verlaufenden Ebene einen zwischen 4° und 6° liegenden Winkel (α) einschließt.
- Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Wandung des Deckels (5) gegenüber der rechtwinklig zur Achse des Abschirmrings (4) verlaufenden Ebene einen Winkel (α) von 5° einschließt.
- Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß der Deckel (5) ein durch Spritzgießen hergestelltes Bauteil ist.
- Vorrichtung nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß der Deckel (5) eine Wandstärke hat, die in Abhängigkeit von der Frequenz der zu übertragenden elektromagnetischen Wellen zwischen 1,5 mm und 8,5 mm liegt.
