Abstract
Description
Die Erfindung betrifft eine Antenne mit Parabolreflektor der im Oberbegriff des Patentanspruchs 1 genannten Art.The invention relates to an antenna with a parabolic reflector the type mentioned in the preamble of claim 1.
Zum gleichzeitigen Empfang von Millimeterwellen aus z.B. vier verschiedenen Richtungen ist es bekannt, vier Einzel antennen zu verwenden.For the simultaneous reception of millimeter waves from e.g. four different directions it is known four individual to use antennas.
Der Erfindung liegt die Aufgabe zugrunde, den Stand der Technik zu verbessern. Insbesondere sollen bei einer Antenne der im Oberbegriff des Patentanspruchs 1 genannten Art die Antennenabmessungen möglichst klein und das Ge wicht möglichst niedrig gehalten werden. The invention has for its object the state of the Improve technology. In particular, at a Antenna mentioned in the preamble of claim 1 Type the antenna dimensions as small as possible and the Ge weight should be kept as low as possible.
Die Aufgabe wird bei einer Antenne der oben bezeichneten Art durch die im kennzeichnenden Teil des Patentan spruchs 1 genannten Merkmale gelöst. Durch die Anordnung von mindestens zwei Speisehörnern im Brennpunktbereich eines Parabolreflektors ist lediglich ein Parabolreflektor erforderlich, um in oder aus mindestens zwei verschiedenen Richtungen senden bzw. empfangen zu können.The task is for an antenna of the above Kind by those in the characterizing part of the patent claim 1 resolved characteristics. By the arrangement of at least two food horns in the focal area a parabolic reflector is only a parabolic reflector required to be in or out of at least two different ones To be able to send or receive directions.
Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Bei Ausgestaltung der Erfindung nach Anspruch 2 wird ein minimales Stehwellenverhältnis in den Speisehörnern sowie eine minimale Verkopplung der Sende/Empfangs-Kanäle unter einander erzielt. Die Ausgestaltung der Erfindung nach Anspruch 3 erlaubt einen leichten, gedrungenen Aufbau und erfordert keine Justierarbeiten.Advantageous further developments and refinements of Invention are specified in the subclaims. At Embodiment of the invention according to claim 2 is a minimal standing wave ratio in the food horns as well a minimal coupling of the transmit / receive channels under scored each other. The design of the invention according to Claim 3 allows a lightweight, compact structure and does not require any adjustment work.
Die Erfindung wird nun anhand eines Ausführungsbeispiels näher erläutert. Es zeigen im einzelnen:The invention is now based on an embodiment explained in more detail. The individual shows:
Fig. 1: Strahlengang der Antenne in Elevation; Fig. 1: Beam path of the antenna in elevation;
Fig. 2: Strahlengang der Antenne in Azimuth; Fig. 2: Beam path of the antenna in azimuth;
Fig. 3: Perspektivische Darstellung der Antenne; Fig. 3: Perspective view of the antenna;
Fig. 4: Perspektivische Darstellung der Speisehörner. Fig. 4: Perspective view of the food horns.
In Fig. 1 ist der Strahlengang der Antenne in Elevation dargestellt. Mit 1 ist der Parabolreflektor und mit 3 sind die Speisehörner bezeichnet, die so ausgelegt sind, daß mit ihnen auch empfangen werden kann. Die Speisehörner sind, wie ersichtlich, in Offsetlage angeordnet, also jenseits des Strahlenganges der reflektierten Wellen, wie am Beispiel von drei reflektierten Strahlen 11, 12 und 13 es dargestellt ist.In Fig. 1 the beam path of the antenna is shown in elevation. With 1 the parabolic reflector and with 3 the food horns are designated, which are designed so that they can also receive. As can be seen, the feed horns are arranged in an offset position, that is to say beyond the beam path of the reflected waves, as is illustrated using the example of three reflected beams 11 , 12 and 13 .
Die Speisehörner sind im Brennpunktbereich des Parabol reflektors 1 angeordnet. Der Abstand des Parabolreflektors von den Speisehörnern ist in der Figur mit f bezeichnet.The food horns are arranged in the focal point area of the parabolic reflector 1 . The distance of the parabolic reflector from the food horns is denoted by f in the figure.
In Fig. 2 ist der Strahlengang der Antenne im Azimuth dargestellt (Draufsicht). Die in Fig. 1 hintereinander liegenden, beispielsweise vier Speisehörner 3 sind in Fig. 2 mit 31 bis 34 bezeichnet. Ansonsten sind gleiche Bauteile mit gleichen Bezugszeichen versehen. Durch die in Reihe angeordneten Speisehörner 31 bis 34 ergeben sich, wie die Fig. 2 zeigt, vier unterschiedliche Sende/Emp fangs-Richtungen der Antenne. Die jeweils gewünschte Sende/Empfangs-Richtung kann durch Umschalten der Speise hörner ausgewählt werden.In FIG. 2, the beam path of the antenna is shown in azimuth (top view). The one behind the other in Fig. 1 lying, for example, four feed horns 3 are designated 2 with 31 to 34 in Fig.. Otherwise, the same components are provided with the same reference numerals. The feed horns 31 to 34 arranged in series result, as shown in FIG. 2, in four different transmit / receive directions of the antenna. The desired send / receive direction can be selected by switching the feed horns.
In Fig. 3 ist die Anordnung der Antenne mit Parabolreflek tor 1, dessen Fläche A×B ist, mit Speisehörnern 3 und dem Gestell 2 perspektivisch dargestellt.In Fig. 3, the arrangement of the antenna with parabolic reflector 1 , whose area is A × B, with food horns 3 and the frame 2 is shown in perspective.
Wie Fig. 4 zeigt, sind die Speisehörner aus einem gemein samen Metallblock gefertigt, so daß die Sende/Empfangs- Richtungen der Antenne fixiert sind und daher keine auf wendigen Justierarbeiten erfordern.As shown in FIG. 4, the food horns are made from a common metal block, so that the send / receive directions of the antenna are fixed and therefore do not require any agile adjustment work.
