Description

Gegenstand der Erfindung ist ein Breitbandstrahler, der dadurch gekennzeichnet ist, daß er aus mehreren in der Hauptwindebene hintereinander angeordneten Körpern besteht, welche eine solche Stärke besitzen, daß der atmosphärische Einfluß auf ihre elektrischen Eigenschaften vernachlässigbar, aber ihr Windwiderstand kleiner als der - eines Einfachstrahlers ,gleicher elektrischer Eigenschaften ist.The invention relates to a broadband radiator, which is characterized is that it consists of several bodies arranged one behind the other in the main wind plane exists, which have such a strength that the atmospheric influence on their electrical properties are negligible, but their wind resistance is smaller than that of a single radiator, has the same electrical properties.

Die Fig. i zeigt als Ausführungsbeispiel zwei z. B. für eine Richtantennenwand als Dipol zum Einsatz zu bringende Strahler S1 und S.., von denen jeder aus vier rohrförmigen oder andersgeformten Körpern K1 bis K4 bzw. h:5 bis K8 besteht. Die Befestigung an der Richtantennenwand erfolgt durch rohrförmige Streben St, und St., welche die einzelnen Körper hier im Spannungsknoten haltern. Die Speisung erfolgt beispielsweise über die Parallelleitungen Sp, welche den Körper K4 des Strahlers Si und den Körper K8 des Strahlers S, unmittelbar speisen, während die entsprechenden übrigen Körper strahlungsgekoppelt sind. Der Durchmesser der rohrförmigen Körper ist so groß gewählt, daß der atmosphärische Einfluß hinsichtlich der Änderung des Wellenwiderstandes und damit des Scheinwiderstandes vernachlässigbar ist, aber andererseits so klein gewählt, daß der Windwiderstand kleiner als der eines Einfachstrahler gleicher elektrischer Eigenschaft ist. Der gegenseitige Abstand e zwischen den einzelnen Körpern eines Strahlers ist so bemessen, daß ein Körper, z. B. KZ, im Windschatten des ihm vorgeordneten Körpers, z. B. K1, liegt. Solche erfindungsgemäß gestalteten Strahler bieten infolge des geringen Windwiderstandes die Möglichkeit, für die Bemessung der Halterung bzw. der gesamten Trägerkonstruktion des Antennenaufbaues kleinere ineclianische Kräfte zugrunde zu legen als bei einer Ausrüstung des Antennensystems mit Einfachstrahlern, die die gleiche elektrische Eigenschaft besitzen.Fig. I shows as an embodiment two z. B. for a directional antenna wall Radiators S1 and S .. to be used as a dipole, each of which consists of four tubular or differently shaped bodies K1 to K4 or h: 5 to K8. the It is attached to the directional antenna wall using tubular struts St, and St., which hold the individual bodies here in the tension node. The feed takes place for example via the parallel lines Sp, which the body K4 of the radiator Si and the body K8 of the radiator S, feed directly, while the corresponding rest of the body are radiation-coupled. The diameter of the tubular body is chosen so large that the atmospheric influence with regard to the change in Wave resistance and thus the impedance is negligible, but on the other hand chosen so small that the wind resistance is smaller than that of a single radiator the same electrical property is. The mutual distance e between each Bodies of a radiator is dimensioned so that a body, e.g. B. KZ, in the slipstream of the body upstream of it, e.g. B. K1, is located. Such designed according to the invention Due to the low wind resistance, spotlights offer the possibility of dimensioning the bracket or the entire support structure of the antenna structure is smaller Ineclianic forces should be used as a basis than when equipping the antenna system with single radiators that have the same electrical properties.

In der Fig. 2 ist eine Draufsicht der mittels Streben Stl und St= gehalterten beiden Strahler S1 und SE wiedergegeben, aus der erkennbar ist, in welcher Weise eine gleichphasige Speisung der beiden Strahler erfolgen kann. Zu diesem Zweck sind die einzelnen Körper der beiden Strahler S1 und S, an ihren einander zugekehrten Enden durch Stege Stel und Ste, untereinander verbunden, so daß die gleichphasige Speisung über die an diese Stege angeschlossene Speiseleitung Sp erfolgen kann. Die Stege können auch durch Leiter L gemäß Fing. 3 ersetzt werden, die von den Körpern strahlenförmig zu einem Speisepunkt führen. Man erhält dann eine genau gleichphasige Speisung infolge der gleichen Laufzeiten zu den Körpern.In Fig. 2 is a plan view of the means of struts Stl and St = supported two radiators S1 and SE reproduced, from which it can be seen in which Way an in-phase supply of the two radiators can take place. To this end are the individual bodies of the two radiators S1 and S, facing each other Ends by webs Stel and Ste, interconnected so that the in-phase Can be fed via the feed line Sp connected to these webs. The webs can also be through ladder L according to Fing. 3 to be replaced by the bodies Radiate to a feed point. One then obtains an exactly in-phase one Feeding due to the same transit times to the bodies.
