Description

Anschluß einer symmetrischen Speiseleitung an ein unsymmetrisches Kabel In der Hochfrequenztechnik tritt vielfach die Aufgabe auf, an ein als Energieleitung dienendes Kabel, das an sich unsymmetrisch ist und beispielsweise aus einem rohrförmigen Außenleiter i und einem Innenleiter 2 besteht,. eine symm°trische Einrichtung, die auch Energieleitung sein kann, anzuschließen. Es ist beispielsweise zur Speisung eines Dipols notwendig, daß die Speiseleitung desselben vollkommen symmetrisch angekoppelt wird. Die Erfindung gibt nun .einen neuen Weg an, wie ein derartiger Anschluß einer symmetrischen Speiseleitung erfolgen kann.Connection of a symmetrical feed line to an asymmetrical one Cable In high frequency technology, the task often occurs as a power line Serving cable, which is asymmetrical in itself and, for example, made of a tubular Outer conductor i and an inner conductor 2 consists. a symmetrical device that power line can also be connected. It is for example for feeding of a dipole necessary that the feed line of the same is coupled perfectly symmetrically will. The invention now provides a new way of connecting a symmetrical feed line can be made.

Es wird erfindungsgemäß vorgeschlagen, den Innenleiter und Außenleiter eines unsymmetrischen (konzentrischen t Kabels am Kabelende kurzzuschliel.'reti und den Innenleiter im Abstand 2 2 vom Kabelende aufzutrennen und die symmetrische Speiseleitung in den aufgetrennten Innenleiter einzuschalten.It is proposed according to the invention, the inner conductor and outer conductor short-circuit an asymmetrical (concentric t cable at the end of the cable and cut the inner conductor at a distance of 2 2 from the end of the cable and the symmetrical one Switch on the feed line in the disconnected inner conductor.

In der Abbildung ist eine beispielsweise Ausführungsform der Erfindung dargestellt. i und 2 bedeutete Außenleiter und Innenleiter eines unsymmetrischen (konzentrischen Kabels, 3 und y .l den Anschluß einer symmetrischen Speiseleitung. Di - bedeutet den Dipol. Innenleiter und Außenleiter i und 2 sind am Ende des Kabels kurzgeschlossei-t. Beispielsweise kann eitre leitende Scheibe S verschiebbar so angeordnet sein, daß der Kurzschlußpunkt :einstellbar ist. In der Lntfernung a_ 2 vom Kabelende ist der Innenleiter aufgetrennt. Durch den Kurzschluß am Ende des Kabels ist dieser Punkt K in i:2 Entfernung ebenfalls ein Kurzschlußpunkt, d. h. ein Knotenpunkt der Kabelleitung. Führt man jetzt, wie die Zeichnung zeigt, von diesen Trennstellen zwei Leitungen 3 und .1, ab, so werden beide gegenphasig gespeist. Die Leitungen 3 und .1 selbst sind symmetrisch.The figure shows an exemplary embodiment of the invention shown. i and 2 meant outer conductor and inner conductor of an unbalanced one (concentric cable, 3 and y .l the connection of a symmetrical feed line. Di - means the dipole. Inner conductor and outer conductor i and 2 are at the end of the cable short-circuited. For example, a conductive disk S can be slidable be arranged that the short-circuit point: is adjustable. At distance a_ 2 at the end of the cable the inner conductor is separated. The short circuit at the end of the Cable, this point K at i: 2 distance is also a short-circuit point, i. H. a junction of the cable line. If you now lead from These separation points two lines 3 and .1, so both are fed in phase opposition. The lines 3 and .1 themselves are symmetrical.

Selbstverständlich läßt sich die Erfindung auch für den umgekehrten Fall verwenden, bei dem z. B. der Übergang von einer symmetrischen Leitung in ein unsymmetrisches Kabel gewünscht wird.Of course, the invention can also be used for the reverse Use case where e.g. B. the transition from a symmetrical line to a unbalanced cable is desired.
