Patentiert im Deutschen Reiche vom 16. September 1926 ab. Das Hauptpatent hat angefangen am 9. Juli 1925.Patented in the German Empire on September 16, 1926. The main patent started on July 9, 1925.
Die Priorität der Anmeldung in Großbritannien vom 7. Oktober 1925 ist in Anspruch genommen.The priority of the application in Great Britain on October 7, 1925 has been claimed.
Die Erfindung betrifft eine Verbesserung und weitere Ausgestaltung der Antennenanordnung gemäß Patent 427 599.The invention relates to an improvement and a further embodiment of the antenna arrangement according to patent 427,599.
In dem Hauptpatent wird eine Antenne beschrieben, bei der eine starke Richtwirkung dadurch erzielt wird, daß die Ausstrahlung von jeder abwechselnden halben Wellenlänge unterdrückt wird.In the main patent, an antenna is described in which a strong directivity is achieved by broadcasting from each alternate half wavelength is suppressed.
Gemäß der vorliegenden Erfindung werden eine Anzahl solcher Antennen miteinander gekuppelt bzw. derart verbunden, daß Ströme der richtigen Frequenz in jeder der Antennen Ströme derselben Phase in benachbarten Antennen hervorrufen.In accordance with the present invention, a number of such antennas are interconnected coupled so that currents of the correct frequency in each of the antennas Generate currents of the same phase in neighboring antennas.
In einem solchen System braucht dann nur eine, der Antennen direkt erregt zu werden, und zwar zweckmäßig nur die Mitte.In such a system only one of the antennas needs to be excited directly, and only the middle is practical.
Drei Ausführungsbeispiele der Erfindung sind auf der Zeichnung in drei Abbildungen dargestellt.Three embodiments of the invention are shown in the drawing in three figures shown.
In Abb. ι sind 1 bis 5 fünf Antennen gemäß dem Hauptpatent, jede bestehend aus zwei strahlenden Abschnitten/? von ungefähr einer halben Wellenlänge und einem nicht-In Fig. 1 to 5 are five antennas according to the main patent, each consisting of two radiating sections /? of about half a wavelength and a non-
strahlenden Teil 5, der durch eine Spule oder ein anderes elektrisches Äquivalent von einer halben Wellenlänge gebildet wird. Die Antennen ι bis 5 sind mit den benachbarten durch Kreise C gekuppelt, die zweckmäßig auf die Wellenlänge abgestimmt sind. T ist ein Transformator, von dem aus eine oder mehrere Antennen, beispielsweise die mittlere, erregt wird.radiating part 5 formed by a coil or other electrical equivalent of half a wavelength. The antennas ι to 5 are coupled to the neighboring ones by circles C, which are suitably matched to the wavelength. T is a transformer from which one or more antennas, for example the middle one, is excited.
Von dieser erregten Antenne wird die Energie durch die Kopplungskreise C auf die anderen Antennen übertragen, so' daß, wenn die Kopplungskreise richtig eingestellt sind, alle Antennen in Phase schwingen.From this excited antenna, the energy is transmitted through the coupling circuits C to the transmitted to other antennas so that, if the coupling circuits are correctly set, all antennas swing in phase.
Abb. 2 und 3 zeigen vier -direkt miteinander verbundene Antennen.Fig. 2 and 3 show four antennas directly connected to one another.
In Abb. 2 enthält jede der Antennen 1 bis 4 drei strahlende Teile JR und zwei nichtstrahlende Teile S. Die strahlenden Endteile jeder Antenne sind paarweise direkt verbunden, so daß das Antennensystem eine geschlossene Leitung darstellt.In Fig. 2, each of the antennas 1 to 4 contains three radiating parts JR and two non-radiating parts Parts S. The radiating end parts of each antenna are directly connected in pairs, see above that the antenna system is a closed line.
Die Verbindungsstelle der Antennen 2, 3 ist mit dem Transformator T verbunden.The connection point of the antennas 2, 3 is connected to the transformer T.
Die Anordnung gemäß Abb. 3 unterscheidet sich von der gemäß Abb. 2 nur dadurch, daß die nichtstrahlenden Teile S eine Länge haben, die elektrisch einer halben Wellenlänge äquivalent ist, und so gegeneinander verlaufen, daß die Strahlung aufgehoben wird.The arrangement according to Fig. 3 differs from that according to Fig. 2 only in that the non-radiating parts S have a length which is electrically equivalent to half a wavelength and run against each other in such a way that the radiation is canceled.
