Patentiert im Deutschen Reiche vom 11. März 1909 ab.Patented in the German Empire on March 11, 1909.
Zur Herstellung von Luftleitergebilden für die drahtlose Telegraphie, Telephonie und
Kraftübertragung wurden bisher stets Drähte aus verschiedenstem Material benutzt.
Da die einzelnen Drähte biegsam und doch von großer Zerreißfestigkeit sein mußten, so
verwandte man vorzugsweise Litzen aus dünnen Phosphor- oder Silicium-Bronzedrähten
und nahm einen verhältnismäßig hohen Leitungswiderstand in Kauf.For the production of air conductor structures for wireless telegraphy, telephony and power transmission, wires made of the most varied of materials have always been used.
Since the individual wires had to be flexible and yet of high tensile strength, it was preferred to use litz wires made of thin phosphorus or silicon bronze wires and to accept a relatively high line resistance.
Um diesen Widerstand herabzusetzen, wurden dann Versuche gemacht, eine Stahl- oder j Bronzelitze mit Kupferdrähten zu umspinnen oder zu umklöppeln.In order to reduce this resistance, attempts were then made to use a steel or j Spinning or bobbin lace around bronze braid with copper wires.
Alle diese Versuche ergaben jedoch kein günstiges Resultat, da entweder eine elektrolytische Zersetzung eines der beiden Metalle eintrat oder die weiche Kupferumspinnung sich von der harten Seele leicht ablöste und zerriß.However, none of these attempts gave a favorable result, as either an electrolytic one Decomposition of one of the two metals occurred or the soft copper wrapping easily detached itself from the hard soul and tore.
Alle bisher genannten Antennendrähte haben noch den gemeinsamen Nachteil, daß man zur Herstellung von biegsamen und geschmeidigen Seilen einzelne Drähte von sehr kleinem Krümmungsradius benutzen muß. Hierdurch entstehen aber erhebliche, schädliche Strahlungsverluste. All antenna wires mentioned so far have the common disadvantage that one single wires of very small size for making flexible and supple ropes Must use radius of curvature. However, this results in considerable, harmful radiation losses.
Zur Vermeidung dieser Verluste müßten Volldrähte von großem Durchmesser benutzt werden, deren Anwendung sich jedoch wegen ihres großen Gewichtes und ihrer Unbiegsamkeit verbietet.To avoid these losses, solid wires with a large diameter would have to be used However, their application is due to their great weight and their inflexibility forbids.
Die vorliegende Erfindung vermeidet alle genannten Nachteile durch die Benutzung von Metallbändern. Die Bänder können aus homogenem Metall bestehen oder aus verschiedenen Metallen zusammengesetzt sein. Außerdem können dieselben besonders gestaltet sein, um ihre Festigkeit zu erhöhen und um die schädliche Randstrahlung zu vermeiden.The present invention avoids all of the disadvantages mentioned by using Metal straps. The bands can be made of homogeneous metal or of different ones Be composed of metals. In addition, they can be specially designed, to increase their strength and to avoid damaging marginal radiation.
Einige Ausführungsbeispiele der Erfindung sind auf der Zeichnung in fünf Figuren dargestellt. Some embodiments of the invention are shown in the drawing in five figures.
Fig. ι zeigt die einfachste Form des Luftleitergebildes im Querschnitt als einfaches Band.Fig. Ι shows the simplest form of the air guide structure in cross section as a simple ribbon.
Fig. 2 zeigt ein solches Band im Querschnitt, bestehend aus einer Seele von Stahl oder Bronze, die mit Kupfer oder Silber plattiert oder nach irgendeinem Verfahren damit überzogen ist.Fig. 2 shows such a band in cross section, consisting of a core of steel or bronze plated with copper or silver, or some process with it is covered.
Fig. 3 zeigt ein Band mit umgebördeltem oder umgewalztem Rand,Fig. 3 shows a band with a flanged or rolled edge,
Fig. 4 ein solches Band, in dessen Rand Litzen oder Drähte auf beliebige Weise eingelegt, eingewalzt oder irgendwie befestigt sind.4 shows such a band, in the edge of which strands or wires are inserted in any desired manner, rolled in or fastened in some way.
Fig. 5 zeigt ein Band, dessen Ränder stärker sind als der normale Bandquerschnitt, beispielsweise ein gewalztes Band mit verstärktem Rand.Fig. 5 shows a band, the edges of which are thicker than the normal band cross-section, for example a rolled strip with a reinforced edge.
