Description

Bei ultrakurzen bzw. Dezimeterwellen verwendet man bekanntlich zur Erhöhung der Frequenzbandbreite Strahler großen Querschnittes, z. B. in Gestalt dicker Rohre.In the case of ultra-short or decimeter waves, it is well known that the Increase in the frequency bandwidth of radiators with a large cross-section, e.g. B. in shape thick pipes.

Es ist ferner bei Antennenanordnungen allgemein bekannt, den Strahler, falls aus räumlichen oder baulichen Gründen erforderlich, kürzer zu machen, als der Abstimmung auf die Arbeitswelle entspricht, und zur Abstimmung und Anpassung eine Induktivität in Reihe mit dem Strahler zu schalten.It is also generally known in antenna arrangements to use the radiator, if necessary for spatial or structural reasons, to make it shorter than corresponds to the adjustment to the working wave, and to adjustment and adaptation to connect an inductor in series with the radiator.

Die vorliegende Erfindung ermöglicht bei derartigen Stabstrahlern großen Querschnittes eine räumliche Verkürzung auf besonders zweckdienliche Weise dadurch, daß, wie Abb. i beispielsweise zeigt, eine in Reihe mit dem Strahler geschaltete Verlängerungsspule so geformt und angeordnet ist, daß ihr Querschnitt im Zuge des Strahlerquerschnittes liegt.The present invention enables such rod radiators large cross-section a spatial shortening in a particularly useful way in that, as Fig. i shows, for example, one connected in series with the radiator Extension coil is shaped and arranged so that its cross-section in the course of Emitter cross-section lies.

Die Spule I' bildet somit die glatte Verlängerung des Strahlers S, wobei sie gleichzeitig als Teil des :Strahlers mitwirkt. Die Feldverteilung wird wesentlich weniger gestört, als wenn die äußeren Umrisse der Spule nicht im Zuge der Umrisse des Strahlers liegen würden. So entsteht eine sehr kompakte Anordnung, insbesondere dann, wenn, wie dargestellt, die Windungen der Spule einfach durch Einschneiden eines schraubenlinigen Spaltes Sp in das Anscblußende des Strahlers hergestellt sind.The coil I 'thus forms the smooth extension of the radiator S, at the same time as part of: the radiator. The field distribution is much less disturbed than when the outer outline of the coil is not in the train the outline of the radiator would lie. This creates a very compact arrangement, especially when, as shown, the turns of the coil simply go through Cutting a helical gap Sp in the connection end of the radiator are made.

Die Festigkeit wird noch erhöht, wenn der rohrförmige Stabstrahler und die Spule durch einen gemeinsamen Isolierstab I gehalten sind oder wenn z. B. ein Teil des Stabstrablers und der Windungsansatz mit Isoliermaterial umpreßt sind.The strength is increased when the tubular rod radiator and the coil are held by a common insulating rod I or if, for. B. a part of the rod strabler and the turn approach are pressed with insulating material.

Während Abb. i einen einzigen aufrecht auf der Erde stehenden Strahler darstellt, zeigt die Abb. 2 als weiteres Ausführungsbeispiel der Erfindung ein symmetrisches Strahlerpaar, von denen jeder gemäß der Erfindung ausgebildet ist. In diesem Fall kann zur Halterung ein einziger durchgehender Isolierkörper I' dienen, der mit entsprechenden Aussparungen für die symmetrische Speiseleitung L versehen ist.While Fig. I a single radiator standing upright on the earth Fig. 2 shows a symmetrical one as a further embodiment of the invention Pair of radiators, each of which is designed according to the invention. In this case can be used for holding a single continuous insulating body I ', the corresponding Recesses for the symmetrical feed line L is provided.

Zum Zwecke der Abstimmung kann eine über die Spule schiebbare Metallhülse angeordnet sein. Die Strahler sind bei den gezeigten Anordnungen z. B. als Rohre kreisrunden O_uerschnittes ausgebildet. Der Querschnitt kann jedoch auch eine elliptische oder ovale oder etwa stromlinienförmige Form gemäß Abb.3 besitzen, wie sie bei Fahrzeugantennen bekanntlich zweckmäßig ist. Die Verlängerungsspule erhält dann die gleiche Querschnittsforrn.For the purpose of voting, a metal sleeve that can be pushed over the coil can be used be arranged. The radiators are in the arrangements shown z. B. as tubes circular O_uschnittes formed. However, the cross section can also be elliptical or oval or roughly streamlined shape as shown in Figure 3, as they are in vehicle antennas is known to be appropriate. The extension coil then has the same cross-sectional shape.
