Die taktische Verwendung von Navigationsanlagen macht es erforderlich, daß die verwendeten Antennensysteme leicht zu transportieren sind. Bei manchen Navigationssystemen werden die Antennensysteme mechanisch, mittels eines Motors, in Rotation versetzt. Derartige Antennensysteme haben jedoch große Abmessungen, sind sehr schwer, und der Antriebsmotor verbraucht verhältnismäßig viel an elektrischer Energie.The tactical use of navigation systems makes it necessary that the antenna systems used be lightweight are to be transported. In some navigation systems, the antenna systems are mechanical, by means of a motor, set in rotation. However, such antenna systems have large dimensions, are very heavy, and the drive motor uses a relatively large amount of electrical energy.
Die kürzlich in Gebrauch genommenen Antennensysteme mit elektronischer Rotation des Strahlungsdiagrammes sind auch noch von zu großen Dimensionen und von zu schwerem Gewicht für den taktischen Einsatz.The antenna systems recently put into use electronic rotation of the radiation diagram are also of too large dimensions and of too heavy weight for tactical use.

Die Erfindung bezieht sich also auf ein Sende-Antennensystem für ein Punkfeuer zur Erzeugung eines rotierenden Strahlungsdiagrammes von der Form einer Cardioide mit überlagertem mehrblättrigem, insbesondere neunblättrigem Diagramm, mit einem Zentralstrahler und mehreren, diesen konzentrisch umgebenden Ringen von als Reflektoren wirkenden parasitären Elementen.The invention thus relates to a transmitting antenna system for a point fire for generating a rotating radiation pattern in the form of a cardioid with a superimposed multi-leaf, in particular nine-leaf diagram, with one central radiator and several, these concentric surrounding rings of parasitic elements acting as reflectors.

In Fig. 1 ist ein Zentralstrahler 1 dargestellt, der auf einem Gegengewicht 4 montiert und von zwei Ringen 2 und von als Monopole 5 ausgebildeten parasitären Elementen konzentrisch umgeben ist.In Fig. 1, a central radiator 1 is shown, which on a counterweight 4 mounted and two rings 2 and is surrounded concentrically by parasitic elements designed as monopoles 5.
Jeder parasitäre Monopol 5 ist gemäß Fig. 2 über eine Diode mit dem Gegengewicht 4 elektrisch verbunden. Ein Schaltsignal wird der Diode 8 über die Hochfrequenz sperrende Drosselspule 7 zugeführt. Das Schaltsignal steuert die Impedanz zwischen dem Monopol 5 und dem Gegengewicht, so- daß entweder ein hoher Widerstand oder ein Kurzschluß zwischen Monopol 5 und Gegengewicht 4, d.h. dem Massepunkt, entsteht.Each parasitic monopole 5 is shown in FIG. 2 via a diode electrically connected to the counterweight 4. A switching signal is fed to the diode 8 via the high-frequency blocking choke coil 7. The switching signal controls the impedance between the monopoly 5 and the counterweight, so that either a high resistance or a short circuit between monopole 5 and counterweight 4, i.e. the mass point, is created.

Strahlungsdiagramm erzeugt. Das Strahlungsdiagramm kann ■ durch Erdung der einzelnen parasitären Elemente in der gewünschten Weise modifiziert werden.Radiation diagram generated. The radiation diagram can ■ can be modified in the desired manner by grounding the individual parasitic elements.
Das bei dem hier in Präge stehenden Navigationssystem benötigte Strahlungsdiagramm besteht aus der Superposition einer Cardioide und eines neunblättrigen Strahlungsdiagrammes. Bei dem hier beschriebenen Antennensystem werden zur Erzeugung des cardioidenförmigen Strahlungsdiagrammes immer einige der parasitären Elemente des inneren Ringes 2 geerdet, und durch die Erdung einiger ausgewählter parasitären Elemente des äußeren Ringes J5 werden die der Cardioide überlagerten neun Strahlungsblätter erzeugt.The one with the navigation system here in stamping The radiation diagram required consists of the superposition of a cardioid and a nine-leaf radiation diagram. In the antenna system described here, some of the parasitic elements of the inner ring 2 grounded, and by the grounding of some selected parasitic elements of the outer ring J5, those of the cardioids are superimposed nine sheets of radiation generated.
Wenn durch diese Maßnahmen das gewünschte Strahlungsdiagramm als feststehendes Diagramm erzeugt worden ist, so kann man dieses Diagramm dadurch rotieren lassen, daß fortlaufend und nacheinander immer andere der parasitären Elemente der Ringe 2 und j5 geerdet werden. Das wird, wie in Fig. 1 angedeutet ist, dadurch erreicht, daß die Signale eines- Taktgenerators 11 zwei rückgekoppelten Schieberegistern zugeführt werden, bei denen die Information periodisch umläuft und von denen das erste seine Ausgangssignale an die parasitären Elemente des inneren Ringes 2 und das zweite seine Ausgangssignale an die parasitären Elemente des äußeren Ringes j5 liefert.If the desired radiation diagram has been generated as a fixed diagram by these measures, then one can Let this diagram rotate by continuously changing the parasitic elements of the Rings 2 and j5 are grounded. This is, as indicated in Fig. 1, achieved in that the signals of a clock generator 11 two feedback shift registers are fed, in which the information periodically and of which the first its output signals to the parasitic elements of the inner ring 2 and the second supplies its output signals to the parasitic elements of the outer ring j5.
Das im Feld entstehende Strahlungsdiagramm hängt für eine gegebene Frequenz der auszustrahlenden Signale von den Durchmessern der Ringe von parasitären Elementen ab.The radiation diagram that arises in the field depends on the for a given frequency of the signals to be emitted Diameters of the rings from parasitic elements.
Eine zweite Ausführungsform besitzt, um das Antennensystem in zwei verschiedenen Frequenzbändern betreiben zu können, vier konzentrische Ringe (15/17 und 14/16) von parasitärenHas a second embodiment in order to be able to operate the antenna system in two different frequency bands, four concentric rings (15/17 and 14/16) of parasitic

Elementen, zwei innere und zwei äußere (Fig. 3)Ί dabei sind die Ringe ]A und 16 - entsprechend ihrem Abstand vom gespeisten Zentralstrahler für das Frequenzband mit den niedrigeren Frequenzen und die Ringe 15 und VJ für das Frequenzband mit den höheren Frequenzen bestimmt. Durch entsprechende Steuersignale werden die parasitären Elemente der einen oder der anderen Ringe unwirksam bzw. wirksam gemacht, je nachdem, in welchem Frequenzband die Antenne gerade betrieben werden soll.Elements, two inner and two outer (Fig. 3) Ί are the rings] A and 16 - determined according to their distance from the fed central radiator for the frequency band with the lower frequencies and the rings 15 and VJ for the frequency band with the higher frequencies. Corresponding control signals render the parasitic elements of one or the other ring ineffective or effective, depending on the frequency band in which the antenna is to be operated.
Bislang sind als parasitäre Elemente nur Monopole besprochen worden, es können jedoch gemäß einer weiteren Ausführungsform (Fig. 4) auch parasitäre Dipole verwendet werden, um die gewünschte Form des Strahlungsdiagrammes herzustellen. Bei dieser Ausführungsform sind die Dipolhälften l8A und l8B mittels einer Diode 19 überbrückt, deren einer Anschluß über eine Drossel 21 mit dem Massepunkt, d.h. mit dem Gegengewicht 4, verbunden ist, während am anderen Anschluß über eine weitere Drossel 20 das Schaltsignal zugeführt wird. Das Schaltsignal bewirkt, daß die Diode 19 .für die Hochfrequenz entweder eine Trennung oder einen Kurzschluß für die Dipolhälften 18A und l8B darstellt, wodurch deren Strahlungscharakteristik gesteuert wird.So far, only monopoles have been discussed as parasitic elements, but according to a further embodiment (FIG. 4), parasitic dipoles can also be used to to produce the desired shape of the radiation pattern. In this embodiment, the dipole halves 18A and 18B are bridged by means of a diode 19, one terminal of which is connected via a throttle 21 is connected to the earth point, i.e. to the counterweight 4, while at the other connection via a further choke 20 is supplied with the switching signal. The switching signal causes the diode 19 .For the high frequency represents either a separation or a short circuit for the dipole halves 18A and 18B, whereby their Radiation characteristics is controlled.
Bei einem weiteren Ausführungsbeispiel, das schematisch in Fig. 5 dargestellt ist, sind anstatt eines einzigen parasitären Elementes mehrere übereinander angeordnet, um, wie an sich bekannt, eine Verbesserung der Richtwirkung in der Vertikalen zu bekommen. Bei dieser Ausführungsform sind parasitäre Dipole 27, 28 und 29 übereinander angeordnet, und die einzelnen Dipolhälften 2?A / 27B, 28A / 28B, 29A / 29B der Dipole sind getrennt an Drosseln 22 bzw.In a further embodiment, which is shown schematically in Fig. 5, instead of a single parasitic element several arranged one above the other in order to, as is known per se, to get an improvement in the directivity in the vertical. In this embodiment parasitic dipoles 27, 28 and 29 are arranged one above the other, and the individual dipole halves 2? A / 27B, 28A / 28B, 29A / 29B of the dipoles are separated by chokes 22 resp.
