Description
Rahmenantenne mit ringförmigem Rahmengestell Die Erfindung bezieht sich auf Rahmenantennen, bei denen die Wicklung auf mit dem Rahmengestell verbundenen radial nach innen gerichteten Zwischenhaltern angeordnet ist, und besteht darin, daß die Zwischenhalter, um die auf ihnen angeordnete Wicklung spannen zu können, gegen das Rahmengestell radial verrückbar sind.Loop antenna with ring-shaped frame The invention relates on loop antennas, in which the winding is connected to the frame is arranged radially inward intermediate brackets, and consists in that the intermediate holders in order to be able to tension the winding arranged on them, are radially displaceable against the frame.
In der Zeichnung sind Beispiele des. Erfindungsgegenstandes dargestellt. In Abb. i ist i das umlaufende, feste Rahmengestell, das aus einem Holzreifen bestehen kann. An einer Reihe von tunlichst gleich weit voneinander entfernten Stellen des Umfanges sind die als Zwischenhalter dienenden. Isolatoren 2, 3, 4, 5, 6 und 7 eingehängt. 8 ist die in die Isolatoren eingelegte Wicklung. In Abb. 2 und 3 ist ein Stück des ringförmigen Rahmengestells i mit einem der aufgehängten Isolatoren in größerem Maßstabe dargestellt. Die Aufhängung des Isolators ist durch einem Draht 9 bewirkt, der an einem Ende zu einem Haken ,gebogen ist und auf dessen anderes Ende ein Gewinde geschnitten ist. i o ist eine Mutter, die das Herausgleiten des Drahtes aus dem Reifen i verhütet und mittels der der Isolator 2 gegen den Rahmen i in radialer Richtung nach außen verrückt werden kann. Der Isolator 2 enthält .ein Loch i i, in das der Drahthaken 9 eingreift. Am Rande des Isolators 2 befinden sich schräg gestellte Einschnitte 12, die zur Aufnahme der Wicklung 8 dienen. In der Abb.4 ist ein als Halter dienendes Isolierplättchen 13 dargestellt, wie es geformt sein kann, wenn nur eine einlagige Wicklung untergebracht werden soll. Die Bezeichnungen i, 9, i o und i i haben die eiche Bedeutung ffl U wie in Abb. -- und 3. The drawing shows examples of the subject matter of the invention. In Fig. I i is the surrounding, fixed frame, which can consist of a wooden hoop. At a number of points on the circumference that are as far apart as possible are those that serve as intermediate brackets. Insulators 2, 3, 4, 5, 6 and 7 attached. 8 is the winding inserted into the insulators. In Figs. 2 and 3 a piece of the ring-shaped frame i with one of the suspended insulators is shown on a larger scale. The suspension of the insulator is effected by a wire 9 which is bent at one end to form a hook and on the other end of which a thread is cut. io is a nut which prevents the wire from sliding out of the tire i and by means of which the insulator 2 can be displaced outward in the radial direction relative to the frame i. The insulator 2 contains .ein hole ii into which the wire hook 9 engages. At the edge of the insulator 2 there are inclined incisions 12 which are used to accommodate the winding 8. 4 shows an insulating plate 13 serving as a holder, as it can be shaped if only a single-layer winding is to be accommodated. The designations i, 9, io and ii have the same meaning ffl U as in Fig. - and 3.
