Derartige Antennen werden wegen des Subreflektors auch als "Cassegrain"-Antennen bezeichnet. Sie werden beispielsweise für Mobilfunk eingesetzt. Antennen nach der eingangs erwähnten DE 197 25 047 A1 sind konstruktiv relativ einfach aufgebaut, da der als "Erreger" dienende Strahler mit Subreflektor vom zentral am Reflektor befestigten Hohlleiter getragen wird. Der Hohlleiter ragt durch den Reflektor hindurch. Auf dessen Rückseite ist eine Radioboxangebracht, die an den Hohlleiter angeschlossen ist. Von der Radiobox aus führt ein koaxiales Hochfrequenzkabel zu einer Sende- und Empfangseinrichtung. In der Radiobox sind elektrische und elektronische Bauteile sowie ein Übertragungsweg für die elektromagnetrischen Wellen untergebracht. Diese bekannte Antenne ist zur Übertragung einer linear polarisierten Welle einer Frequenz bzw. eines Frequenzbandes ausgelegt. Such antennas are also called "Cassegrain" antennas because of the sub-reflector designated. They are used, for example, for mobile radio. Antennas after the DE 197 25 047 A1 mentioned at the outset are structurally relatively simple since the spotlight serving as an "exciter" with a subreflector attached from the center to the reflector Waveguide is worn. The waveguide protrudes through the reflector. On whose A radio box is attached to the back, which is connected to the waveguide. Of the Radiobox leads a coaxial radio frequency cable to a transmit and Receiving device.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Antenne so weiterzubilden, daß ihre Übertragungskapazität ohne wesentliche Änderungen ihres Aufbaus vergrößert werden kann.The invention has for its object the antenna described above to further that their transmission capacity without significant changes in their Construction can be enlarged.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß zwischen der Radiobox und dem Hohlleiter eine Polarisationsweiche zur simultanen Übertragung zweier orthogonal aufeinander stehender, linear polarisierter Wellen angebracht ist, die einen ersten und einen zweiten Eingang mit im wesentlichen rechteckigem lichtem Querschnitt sowie einen an den Hohlleiter anschließbaren Ausgang hat,
  • daß in der Polarisationsweiche zwei Hohlleiterstrecken vorhanden sind, von denen die eine geradlinig zwischen dem ersten Eingang und dem Ausgang der Polarisationsweiche verläuft, während die andere mit um 90° gebogenem Verlauf am zweiten Eingang der Polarisationsweiche beginnend im Verlauf der geradlinigen Hohlleiterstrecke in dieselbe einmündet und
  • daß die geradlinige Hohlleiterstrecke im Eingangsbereich um 90° gedreht ist, so daß die großen Achsen der beiden in der gleichen Ebene liegenden Eingänge der Polarisationsweiche rechtwinklig zueinander angeordnet sind.
According to the invention, this object is achieved by
  • that between the radio box and the waveguide there is a polarization switch for the simultaneous transmission of two orthogonally standing, linearly polarized waves, which has a first and a second input with an essentially rectangular light cross section and an output that can be connected to the waveguide,
  • that there are two waveguide sections in the polarization switch, one of which runs in a straight line between the first input and the output of the polarization switch, while the other opens into the same with a curve bent by 90 ° at the second input of the polarization switch in the course of the straight waveguide section and
  • that the rectilinear waveguide section in the entrance area is rotated by 90 °, so that the major axes of the two inputs of the polarization switch located in the same plane are arranged at right angles to one another.

Durch den Einbau der Polarisationsweiche kann die Antenne ohne grundsätzliche Änderung ihres Aufbaus zur Übertragung von zwei getrennten elektromagnetischen Wellen eingesetzt werden. Die Übertragungskapazität der Antenne ist dadurch auf einfache Weise verdoppelt. Dabei kann die in ihren Abmessungen selbst kleine Polarisationsweiche anstelle einer üblichen einfachen Hohlleiterstrecke angeordnet werden, so daß die Radiobox bis auf ein angepaßtes "Innenleben" unverändert bleiben kann. Für ihre Montage am Reflektor der Antenne muß daher nichts geändert werden. Die Polarisationsweiche ersetzt also einen bisher verwendeten Hohlleiterabschnitt zum Anschluß an den Hohlleiter der Antenne. Der Anschluß der Radiobox an die Polarisationsweiche ist ebenfalls sehr einfach, da die beiden Eingänge derselben in einer Ebene liegen. Die Entkopplung der beiden linear polarisierten Wellen ist auf einfache Weise dadurch sichergestellt, daß die großen Achsen der beiden Eingänge der Polarisationsweiche rechtwinklig zueinander verlaufen. By installing the polarization switch, the antenna can be used without any basic Modification of their structure for the transmission of two separate electromagnetic Shafts are used. The transmission capacity of the antenna is therefore up easily doubled. It can even be small in its dimensions Polarization switch arranged instead of a conventional simple waveguide section be so that the radio box remain unchanged except for an adapted "inner life" can. Nothing needs to be changed for their mounting on the reflector of the antenna. The polarization switch thus replaces a previously used waveguide section Connection to the waveguide of the antenna. The connection of the radio box to the Polarization switch is also very simple, since the two inputs of the same in one Level. The decoupling of the two linearly polarized waves is simple Way ensured that the major axes of the two inputs of the Polarization switch run perpendicular to each other.

    • Auf einem nur ausschnittsweise angedeuteten Mast 1 ist ein parabolischer Reflektor 2 einer Antenne zur Übertragung elektromagnetischer Wellen montiert. Zentral im Reflektor 2 ist ein elektromagnetischer Hohlleiter 3 befestigt, an dessen Ende im Brennpunkt der Antenne ein als Subreflektor ausgebildeter Erreger 4 angebracht ist. An der Rückseite des Reflektors 1 befindet sich ein Befestigungselement 5, über welches derselbe am Mast 1 befestigt werden kann. Am Befestigungselement 5 ist auf dessen anderer Seite eine Radiobox 6 angeordnet, die einerseits mit dem Hohlleiter 3 und andererseits mit einem Koaxialkabel 7 verbunden ist, das zu einer nicht mit dargestellten Sende- und Empfangseinrichtung für hochfrequente Signale führt. Statt des Koaxialkabels 7 könnte auch ein Hohlleiter verwendet werden.A parabolic reflector 2 is on a mast 1, which is only indicated in sections an antenna for the transmission of electromagnetic waves. Central in Reflector 2 is attached to an electromagnetic waveguide 3, at the end of which Focal point of the antenna is an exciter 4 designed as a sub-reflector. On the back of the reflector 1 is a fastener 5, via which the same can be attached to the mast 1. On the fastener 5 is on the on the other hand, a radio box 6 is arranged, on the one hand with the waveguide 3 and on the other hand, is connected to a coaxial cable 7, which to a not shown Transmitter and receiver for high-frequency signals leads. Instead of the coaxial cable 7, a waveguide could also be used.

    In der Radiobox 6 sind elektrische und elektronische Bauteile enthalten, wie beispielsweise Konverter und andere Anpassungselemente. Zwischen der Radiobox 6 und dem Hohlleiter 3 ist eine innerhalb des Befestigungselements 5 liegende Polarisationsweiche 8 angebracht, deren genauerer Aufbau aus den Fig. 3 bis 5 hervorgeht.The radio box 6 contains electrical and electronic components, such as for example converters and other adaptation elements. Between the radio box 6 and the waveguide 3 is one located within the fastening element 5 Polarization switch 8 attached, the more precise structure of which is shown in FIGS. 3 to 5 emerges.

    Die Polarisationsweiche 8 hat zwei Hohlleiterstrecken 9 und 10, von denen die Hohlleiterstrecke 9 geradlinig ausgebildet ist. Sie verläuft zwischen einem ersten Eingang E1 der Polarisationsweiche 8 und einem Ausgang A derselben. Die andere Hohlleiterstrecke 10 hat einen um 90° gebogenen Verlauf. Sie beginnt an einem zweiten Eingang E2 der Polarisationsweiche 8 und mündet mit einer Blende B im Verlauf der geradlinigen Hohlleiterstrecke 9 in dieselbe. Zwischen der Blende B und dem ersten Eingang E1 der Polarisationsweiche 8 ist ein Kurzschlußelement 11 in der geradlinigen Hohlleiterstrecke 9 angebracht, das im dargestellten Ausführungsbeispiel aus drei Stiften besteht. Es soll verhindern, das die über die Hohlleiterstrecke 10 zugeführte bzw. in dieselbe einzuspeisende Welle sich in der falschen Richtung ausbreitet. Die Polarisationsweiche 8 ist mit ihrem Ausgang A an den Hohlleiter 3 angeschlossen.The polarization switch 8 has two waveguide sections 9 and 10, of which the Waveguide path 9 is rectilinear. It runs between a first entrance E1 of the polarization switch 8 and an output A of the same. The other Waveguide section 10 has a 90 ° curve. It starts on a second Input E2 of the polarization switch 8 and opens with an aperture B in the course of rectilinear waveguide path 9 in the same. Between panel B and the first Input E1 of the polarization switch 8 is a short-circuit element 11 in the straight line Waveguide path 9 attached, in the illustrated embodiment from three pins consists. It is intended to prevent the supply via the waveguide section 10 or in the same wave to be fed propagates in the wrong direction. The Polarization switch 8 is connected with its output A to the waveguide 3.

    Die geradlinige Hohlleiterstrecke 9 hat in bevorzugter Ausführungsform einen kreisrunden lichten Querschnitt. Sie könnte aber auch quadratisch sein oder einen anderen geeigneten lichten Querschnitt haben. Für die Hohlleiterstrecke 10 ist in bevorzugter Ausführungsform ein rechteckiger lichter Querschnitt vorgesehen. Sie könnte aber auch elliptisch sein oder einen anderen geeigneten lichten Querschnitt haben. Die lichten Querschnitte der beiden Eingänge E1 und E2 sind im wesentlichen rechteckig. Ihre Ecken können abgerundet sein. Das Kurzschlußelement 11 kann auch aus einem Blechstreifen bestehen.In a preferred embodiment, the straight waveguide section 9 has one circular clear cross section. But it could also be square or one have another suitable clear cross-section. For the waveguide section 10 is in preferred embodiment, a rectangular clear cross section is provided. You could but also be elliptical or have another suitable clear cross section. The clear cross sections of the two inputs E1 and E2 are essentially rectangular. Their corners can be rounded. The short-circuit element 11 can also consist of a Metal strips exist.

    Damit die beiden linear polarisierten Wellen ohne Zusatzelemente entkoppelt sind, ist die geradlinige Hohlleiterstrecke 9 im Bereich ihres Eingangs E1 um 90° gedreht. Das kann durch einen in der Hohlleitertechnik üblichen Übergang in kontinuierlicher oder gestufter Ausführung realisiert werden. Die großen Achsen der beiden in einer gemeinsamen bzw. der gleichen Ebene liegenden Eingänge E1 und E2 der Polarisationsweiche 8 stehen dadurch gemäß Fig. 5 senkrecht aufeinander. Die Radiobox 6 mit ihren weiterführenden Übertragungswegen kann dadurch direkt an die Polarisationsweiche 8 angeschlossen werden.So that the two linearly polarized waves are decoupled without additional elements rectilinear waveguide section 9 rotated by 90 ° in the area of its entrance E1. That can due to a transition in continuous or stepped that is common in waveguide technology Execution can be realized. The major axes of the two in a common or inputs E1 and E2 of the polarization switch 8 are on the same level thereby perpendicular to each other according to FIG. 5. The Radiobox 6 with its advanced Transmission paths can thus be connected directly to the polarization switch 8 become.

    Die Polarisationsweiche 8 wird zweckmäßig aus zwei miteinander zu verbindenden Teilen hergestellt, in denen jeweils ein Teil der Hohlleiterstrecken 9 und 10 eingearbeitet ist, beispielsweise durch Fräsen.The polarization switch 8 is expediently made of two parts to be connected to one another produced, in each of which part of the waveguide paths 9 and 10 is incorporated, for example by milling.
