Description
Vorrichtung zur Abstimmung eines aus zwei parallelen Leitern gleicher Länge bestehenden Lecherdrahtsystems Die Erfindung bezieht sich auf ein aus zwei parallelen Leitern, gleicher Länge bestehendes Lecherdrahtsystem, das bei der Erzeugung, Übertragung und beim Empfang hochfrequenter und ultrahochfrequenter Schwingungen Anwendung finden kann. Die Eigenfrequenz eines solchen Systems wird durch die Länge der Leiter ,bedingt. Eine Änderung in der Abstimmung kann also durch Änderung der Länge dieser Leiter erzielt werden. Häufig erfolgt dies mittels einer Kurzschlußbrücke, die längs einer sich parallel zu den Lecherdrähten erstreckenden Schiene verstellt wird. Diese Abstimmungsart bringt aber ernstliche bauliche Schwierigkeiten mit sich, da die erforderliche Schiene ziemlich viel Raum beansprucht und genau parallel zu den Lecherdrähten angeordnet werden muß.Device for tuning one of two parallel conductors the same Length of existing Lecher wire system The invention relates to one of two parallel ladders, of the same length, existing Lecher wire system that is used in the production, Transmission and reception of high-frequency and ultra-high-frequency vibrations Can apply. The natural frequency of such a system is determined by the length the head, conditional. A change in the vote can therefore be made by changing the Length of this ladder can be achieved. Often this is done by means of a short-circuit bridge, which is adjusted along a rail extending parallel to the Lecher wires will. However, this type of coordination brings with it serious structural difficulties, since the rail required takes up quite a bit of space and is exactly parallel to it the Lecher wires must be arranged.
Gegenstand der Erfindung ist eine Vorrichtung einfacher Bauart zur Abstimmung eines Lecherdrahtsystems.The invention is a device of simple design for Coordination of a Lecher wire system.
Nach der Erfindung sind die beiden Leiter des Lecherdrahtsystems über ihre ganze Länge oder über einen Teil ihrer Länge kreisbogenförmig gekrümmt, und zwar derart, daß der Krümmungsradius der beiden Leiter in entsprechenden Punkten der Leiter gleich groß ist, und daß eine um eine Spindel drehbare Kurzschlußbrücke längs des gekrümmten Teiles der Leiter entlang bewegbar wird: Die Erfindung wird an Hand der beiliegenden Zeichnung näher erläutert. In dieser Zeichnung sind die Leiter eines Lecherdrahtsystem,s mit i Fund a bezeichnet. Die Teile a dieser Leiter sind derart gekrümmt, daß der Krümmungsradius in entsprechenden Punkten der Leiter gleich groß ist. Im dargestellten Ausführungsbeispiel ist außerdem der Krümmungsradius in sämtlichen Punkten der gekrümmten Teile gleich groß, da die Leiter gemäß einem Teil eines Kreisumfanges gekrümmt sind. Mit 3 ist eine Kurzschlußbrücke bezeichnet, die um eine sich parallel zu der Ebene des Lecherdrahtsystems erstreckende Spindel q. drehbar ist. Die Kurzschlußbrücke 3 wird bei Drehung der Spindel ¢ längs des gekrümmten Teiles der Leiter i und z entlang bewegt, und infolgedessen wird die Länge des Lecherdrahtsystems geändert.According to the invention, the two heads of the Lecher wire system are over their entire length or over part of their length curved in the shape of an arc of a circle, and in such a way that the radius of curvature of the two conductors in corresponding points the conductor is the same size, and that a short-circuit bridge rotatable about a spindle is movable along the curved portion along the ladder: The invention is explained in more detail on the basis of the accompanying drawing. In this drawing are the Head of a Lecher wire system, s marked with i Fund a. The parts of this ladder are curved in such a way that the radius of curvature in corresponding points of the conductor is the same size. In the illustrated embodiment, the radius of curvature is also The same size in all points of the curved parts, since the conductors according to a Part of a circumference are curved. 3 with a short-circuit bridge is referred to, the spindle extending parallel to the plane of the Lecher wire system q. is rotatable. The short-circuit bridge 3 is when rotating the spindle ¢ along the curved part of the conductors i and z moves along, and as a result, the Changed the length of the Lecher wire system.
Die beschriebene Vorrichtung hat u. a. den Vorzug, daß die Leiter des Lecher drah,tsystems immer die gleiche Länge haben, die Selbstinduktion je Längeneinheit des Systems nahezu unverändert bleibt rund Reflexionen somit vermieden werden. Die Vorrichtung kann eine ganz einfache Bauart haben. Mittel zum Abstützen des gekrümmten Teiles der Leiter sind entbehrlich, so daß keine besonderen Dämpfungen herbeigeführt werden.The device described has inter alia. the merit of the ladder of the Lech wire system always have the same length, the self-induction per unit of length the system remains almost unchanged around reflections thus avoided. the Device can have a very simple design. Means for supporting the curved Part of the ladder can be dispensed with, so that no special attenuation is brought about will.
