Soll ein Dipol (Einfach- oder Faltdipol) mit einer kleineren mechanischen Länge als der normalen elektrischen Länge, ζ. Β. λ/2, ausgeführt werden, so wird hierzu bisher gewöhnlich ein Teil· des Dipols durch eine Induktivität ersetzt. Dies ergibt eine Verschmälerung der Bandbreite, was in vielen Fällen störend ist.Should a dipole (single or folded dipole) with a smaller mechanical length than the normal electrical length, ζ. Β. λ / 2, a part of the dipole is usually replaced by an inductance for this purpose. This results in a narrowing of the bandwidth, which is disruptive in many cases.
Erfindungsgemäß wird die Verkürzung dadurch erzeugt, daß die Dipolschenkel über ihre ganze Länge oder über einen Teil ihrer Länge gewellt sind. Hierdurch läßt sich auch bei starker Verkürzung noch gute Breitbandigkeit erreichen.According to the invention, the shortening is produced in that the dipole legs over their entire length or are wavy over part of their length. As a result, good shortening can still be achieved even with a great deal of shortening Achieve broadband.
Die Zeichnungen zeigen Beispiele der Erfindung. Es stellt darThe drawings show examples of the invention. It shows
Fig. 1 einen verkürzten Dipol im Aufriß, Fig. 2 den Grundriß zu Fig. 1,Fig. 1 is a shortened dipole in elevation, Fig. 2 is the plan of Fig. 1,
Fig. 3 einen zu einem Ring gebogenen Dipol,3 shows a dipole bent into a ring,
Fig. 4 eine andere Ausführungsform.4 shows another embodiment.
Gemäß den Fig. 1 und 2 sind die in üblicher Weise durch ein Mittelstück 1 verbundenen Dipolschenkel 2 gewellt. Die Wellen brauchen nicht gerundet zu sein, sie können auch dreieckförmig, rechteckig oder beliebig anders verlaufen. Gemäß Fig. 3 ist der Dipol zu einem Ring gebogen.According to FIGS. 1 and 2, the dipole legs 2 connected in the usual way by a center piece 1 wavy. The waves do not need to be rounded, they can also be triangular, rectangular or arbitrary run differently. According to Fig. 3, the dipole is bent into a ring.
Nach Fig. 4 sind an den Enden des gewellten Dipols zusätzlich Spangen 3 aus Isolierstoff eingesetzt, die durch die dadurch erzwungene Veränderung der Wellung eine Abstimmveränderung des Betriebsfrequemzbereiches ergeben.According to Fig. 4, clips 3 made of insulating material are also used at the ends of the corrugated dipole, the resulting change in the corrugation, a tuning change in the operating frequency range result.
