Stand der TechnikState of the art
Die Erfindung betrifft einen Multiband-Rundstrahler, insbesondere zum Einbau in eine Fahrzeugkarosserie.The invention relates to a multiband omnidirectional device, in particular for installation in a vehicle body.
Moderne Kraftfahrzeuge werden zunehmend mit Rundfunk und Kommunikationsdiensten ausgestattet, die geeignete Antennenstrukturen zum Senden und Empfangen von Funksignalen benötigen. Die Antennenstrukturen sollten dabei möglichst nicht von der Karosserie des Fahrzeuges hervorstehen, da sie das Design der Fahrzeughülle stören könnten. Aus diesem Grunde ist es wünschenswert, Antennenstrukturen in die Karosserie so einzubauen, dass sie nicht über die Fahrzeughülle hinausragen. Dies ist bereits für Empfangssysteme wie z.B. Radio- oder TV-Empfang bekannt, die teilweise mehrere Antennen verwenden, um einen gewünschten Rundum-Empfang zu erhalten. Weiterhin werden Verstärker eingesetzt, um die Verluste durch die Fehlanpassung an übliche Antennenkabel gering zu halten oder gar auszugleichen.Modern motor vehicles are increasingly being equipped with broadcasting and communication services which require suitable antenna structures for transmitting and receiving radio signals. The antenna structures should not protrude from the body of the vehicle, as they could disturb the design of the vehicle body. For this reason, it is desirable to install antenna structures in the body so that they do not protrude beyond the vehicle body. This is already true for receiving systems such as e.g. Radio or TV reception are known, some use multiple antennas to obtain a desired all-round reception. Furthermore, amplifiers are used to minimize the losses due to the mismatch with conventional antenna cables or even compensate.
Beispielsweise für Mobilfunksysteme ist der Einsatz eines Verstärkers zur Impedanzanpassung in der Regel jedoch zu teuer, weswegen die Antennenstrukturen bislang mit geeigneten Impedanzen vorgesehen wurden, die jedoch aus Platzgründen über die Fahrzeughülle hinausragend angeordnet werden mussten.However, for example, for mobile radio systems, the use of an impedance matching amplifier is generally too expensive, which is why the antenna structures have hitherto been provided with suitable impedances, which, however, had to be arranged protruding beyond the vehicle body for reasons of space.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Multiband-Rundstrahler für die Verwendung für Mobilfunksysteme zur Verfügung zu stellen, dessen Impedanz angepasst werden kann und der eine geringe Bauhöhe aufweist, so dass dieser in der Fahrzeughülle angeordnet werden kann. Diese Aufgabe wird durch den Multiband-Rundstrahler nach Anspruch 1 gelöst.It is therefore an object of the present invention to provide a multiband omnidirectional antenna for use in mobile radio systems whose impedance can be adjusted and which has a low overall height so that it can be arranged in the vehicle casing. This object is achieved by the multiband omnidirectional device according to claim 1.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Further advantageous embodiments of the invention are specified in the dependent claims.
Erfindungsgemäß ist ein Multiband-Rundstrahler mit einer Massefläche und mit einer parallel zur Massefläche angeordnetem Antennenelement vorgesehen. Das Antennenelement weist einen ersten Flächenstrahler auf, der flächig ausgebildet ist und sich parallel zur Massefläche erstreckt und einen zweiten Flächenstrahler, der den ersten Flächenstrahler mit einem Abstand umgibt. Ferner umfasst das Antennenelement mindestens zwei Verbindungselemente, die den ersten und den zweiten Flächenstrahler miteinander verbinden.According to the invention, a multiband omnidirectional antenna is provided with a ground plane and with an antenna element arranged parallel to the ground plane. The antenna element has a first area radiator, which is formed flat and extends parallel to the ground plane and a second area radiator, which surrounds the first area radiator with a distance. Furthermore, the antenna element comprises at least two connecting elements which connect the first and the second area radiators with one another.
Auf diese Weise kann ein Multiband-Rundstrahler geschaffen werden, der eine geringe Bauhöhe aufweist und sich somit zum Einbau in eine Fahrzeughülle eignet, ohne von dieser abzustehen.In this way, a multi-band omnidirectional can be created, which has a low height and thus suitable for installation in a vehicle casing, without standing out from this.
Vorzugsweise sind der erste und der zweite Flächenstrahler koplanar zueinander ausgebildet.Preferably, the first and the second area radiators are coplanar with each other.
Die Verbindungselemente können im Wesentlichen an gegenüberliegenden Rändern des ersten Flächenstrahlers angeordnet sein, um eine geeignete Stromverteilung in den Flächenstrahlern zu erhalten.The connection elements may be arranged substantially on opposite edges of the first area radiator in order to obtain a suitable current distribution in the surface radiators.
Der erste Flächenstrahler ist vorzugsweise rechteckig ausgebildet und der zweite Flächenstrahler weist eine rechteckige Umrandung auf, wobei der zweite Flächenstrahler den Rand des ersten Flächenstrahlers mit einem Abstand umgibt, so dass der zweite Flächenstrahler als um den ersten Flächenstrahler umlaufendes Band ausgebildet sein kann.The first area radiator is preferably rectangular and the second area radiator has a rectangular border, wherein the second area radiator surrounds the edge of the first area radiator with a spacing, so that the second area radiator can be designed as a band revolving around the first area radiator.
Gemäß einer bevorzugten Ausführungsform kann ein dritter Flächenstrahler vorgesehen sein, der den zweiten Flächenstrahler mit einem weiteren Abstand umgibt und insbesondere rechteckig und koplanar zu dem ersten und dem zweiten Flächenstrahler ausgebildet ist, wobei die Verbindungselemente jeweils den ersten, zweiten und dritten Flächenstrahler miteinander verbinden.According to a preferred embodiment, a third area radiator may be provided, which surrounds the second area radiator with a further distance and in particular rectangular and coplanar with the first and the second area radiator is formed, wherein the connecting elements in each case connect the first, second and third surface radiators with each other.
Insbesondere kann mindestens eines der Verbindungselemente ein elektronisches Bauelement aufweisen, um die Impedanzen des Multiband-Rundstrahlers exakt einstellen zu können.In particular, at least one of the connecting elements may have an electronic component in order to be able to set the impedances of the multiband omnidirectional exactly.
Weiterhin kann der Rundstrahler eine Masseanschlussstruktur zum Verbinden der Massefläche mit dem Antennenelement und eine Speiseanschlussstruktur aufweisen, um das Antennenelement mit einem Sendesignal zu speisen.Furthermore, the omnidirectional antenna can have a ground connection structure for connecting the ground plane to the antenna element and a feed connection structure in order to supply the antenna element with a transmission signal.
Vorzugsweise ist die Masseanschlussstruktur flächig, insbesondere rechteckförmig oder trapezförmig ausgebildet und kontaktiert den ersten Flächenstrahler mit einer Kante entlang einem Masseanschlussbereich auf dem ersten Flächenstrahler. Der Masseanschlussbereich verläuft im wesentlichen parallel zur Kante des ersten Flächenstrahlers, an der sich eines der Verbindungselemente anschließt.The ground connection structure is preferably planar, in particular rectangular or trapezoidal, and contacts the first area radiator with an edge along a ground connection region on the first surface radiator. The ground connection region runs essentially parallel to the edge of the first surface radiator, to which one of the connecting elements adjoins.
Gemäß einer weiteren Ausführungsform der Erfindung kann die Speiseanschlussstruktur flächig, insbesondere kreisabschnittförmig, insbesondere halbkreisförmig oder ellipsenabschnittförmig, insbesondere halbelliptisch ausgebildet sein. Die Speiseanschlussstruktur kontaktiert den ersten Flächenstrahler mit seiner geraden Kante entlang einem Speiseanschlussbereich auf dem ersten Flächenstrahler, wobei der Speiseanschlussbereich im Wesentlichen parallel zu einer Kante des ersten Flächenstrahlers verläuft, an der sich ein weiteres der Verbindungselemente anschließt.In accordance with a further embodiment of the invention, the feed connection structure can be designed to be flat, in particular circular section-shaped, in particular semicircular or elliptical section-shaped, in particular semi-elliptical. The feed connection structure contacts the first area radiator with its straight edge along a feed connection region on the first surface radiator, wherein the feed connection region extends substantially parallel to an edge of the first surface radiator, to which another of the connection elements adjoins.
Vorzugsweise erstrecken sich mindestens einer des Speiseanschlussbereichs und des Masseanschlussbereichs innerhalb einer durch Kontaktstellen der Verbindungselemente mit dem ersten Flächenstrahler aufgespannten Ebene.Preferably, at least one of the feed connection region and the ground connection region extend within a plane defined by contact points of the connection elements with the first surface radiator.

In Fig. 1 ist eine Draufsicht auf einen Multiband-Rundstrahler 1 gemäß einer bevorzugten Ausführungsform der Erfindung dargestellt. Der Multiband-Rundstrahler 1 weist eine Massefläche 2 auf, die eine leitfähige, insbesondere metallische Oberfläche aufweist. Mit einem bestimmten ersten Abstand über der Oberfläche der Massefläche 2 ist im Wesentlichen planparallel ein flächiges Antennenelement 3 angeordnet, das ebenfalls aus einem leitfähigen Material gefertigt ist bzw. eine leitfähige Oberfläche aufweist. Insbesondere kann das Antennenelement 3 als Stanzteil gefertigt werden.In Fig. 1 is a plan view of a multi-band omnidirectional 1 according to a preferred embodiment of the invention is shown. The multiband omnidirectional antenna 1 has a ground surface 2 which has a conductive, in particular metallic surface. At a certain first distance above the surface of the ground plane 2, a planar antenna element 3 is arranged substantially plane-parallel, which is likewise made of a conductive material or has a conductive surface. In particular, the antenna element 3 can be manufactured as a stamped part.
Das flächige Antennenelement 3 weist einen ersten Flächenstrahler 4 auf, der eine im Wesentlichen viereckige, vorzugsweise rechteckige Form hat. Der erste Flächenstrahler 4 wird von einem zweiten Flächenstrahler 5 umgeben, dessen Außenkanten ebenfalls ein Rechteck bilden. Der zweite Flächenstrahler 5 umgibt den ersten Flächenstrahler vorzugsweise mit einem vorgegebenen zweiten Abstand, so dass zwischen dem ersten Flächenstrahler 4 und dem zweiten Flächenstrahler 5 ein Schlitz 6 gebildet wird. Der erste Flächenstrahler 4 und der zweite Flächenstrahler 5 stehen über Verbindungselemente 7 miteinander in Verbindung, wobei die Verbindungselemente an gegenüberliegenden Kanten des ersten Flächenstrahlers 4 angeordnet sind und somit eine elektrische Verbindung zwischen dem ersten Flächenstrahler 4 und dem zweiten Flächenstrahler 5 bilden.The planar antenna element 3 has a first surface radiator 4, which has a substantially quadrangular, preferably rectangular shape. The first area radiator 4 is surrounded by a second area radiator 5, whose outer edges also form a rectangle. The second area radiator 5 preferably surrounds the first area radiator with a predetermined second distance, so that a slot 6 is formed between the first area radiator 4 and the second area radiator 5. The first area radiator 4 and the second area radiator 5 are connected to one another via connecting elements 7, wherein the connecting elements are arranged on opposite edges of the first area radiator 4 and thus form an electrical connection between the first area radiator 4 and the second area radiator 5.
Der erste und der zweite Flächenstrahler 4, 5 weisen jeweils unterschiedliche Impedanzen auf, und sind somit für verschiedene Sendefrequenzen optimiert. Die Abmessungen des ersten und des zweiten Flächenstrahlers, der zweite Abstand zwischen dem ersten und zweiten Flächenstrahler, die Größe der Verbindungselemente 7 sind aufeinander abgestimmt, um die Impedanz des jeweiligen Flächenstrahlers 4, 5 einzustellen. Der erste Flächenstrahler 4 weist einen Masseanschlussbereich 8 auf, um dem Antennenelement 3 ein Massepotenzial zur Verfügung zu stellen, und einen Speiseanschlussbereich 9, um das Sendesignal bzw. die Sendesignale dem Antennenelement 3 zur Verfügung zu stellen. Um das Massepotenzial an das Antennenelement 3 anzulegen, ist ein Masseverbindungselement 10 (siehe Fig. 2) vorgesehen, das zwischen dem Antennenelement 3 und der Massefläche 2 angeordnet ist. Das Masseverbindungselement 10 dient als Abstandselement zwischen der Massefläche 2 und dem Antennenelement 3 und ist flächig und als Steg ausgebildet, der mit der Massefläche 2 und dem Masseanschlussbereich 8 des Antennenelementes 3 verbunden ist. Das Masseverbindungselement 10 ist viereckig, insbesondere rechteckig oder trapezförmig ausgebildet. Der Masseanschlussbereich 8 ist im Wesentlichen länglich ausgebildet, so dass eine Kante des Masseverbindungselementes 10 an diesem anliegt. Eine trapezförmige Ausgestaltung des Masseverbindungselementes 10 ist beispielsweise in Fig. 3 gezeigt, das eine Schnittansicht durch den Multiband-Rundstrahler der Fig. 1 entlang der Schnittlinie B-B zeigt.The first and the second area radiators 4, 5 each have different impedances, and are thus optimized for different transmission frequencies. The dimensions of the first and second area radiators, the second distance between the first and second area radiators, the size of the connecting elements 7 are matched to one another in order to set the impedance of the respective area radiator 4, 5. The first area radiator 4 has a ground connection area 8 in order to provide the antenna element 3 with a ground potential, and a feed connection area 9 in order to make the transmission signal or the transmission signals available to the antenna element 3. In order to apply the ground potential to the antenna element 3, a ground connection element 10 (see FIG. 2) is provided, which is arranged between the antenna element 3 and the ground plane 2. The ground connection element 10 serves as a spacer element between the ground plane 2 and the antenna element 3 and is formed flat and as a web which is connected to the ground plane 2 and the ground connection region 8 of the antenna element 3. The ground connection element 10 is quadrangular, in particular rectangular or trapezoidal. The ground connection region 8 is substantially elongate, so that one edge of the ground connection element 10 bears against it. A trapezoidal configuration of the ground connection element 10 is shown, for example, in FIG. 3, which shows a sectional view through the multiband round radiator of FIG. 1 along the section line BB.
An dem Speiseanschlussbereich 9 ist ein Speiseverbindungselement 11 angeordnet, das von dem Antennenelement 3 insbesondere rechtwinklig in Richtung der Massefläche 2 absteht, so dass das Speiseverbindungselement 11 zwischen dem Antennenelement 3 und der Massefläche 2 angeordnet ist. Das Speiseverbindungselement 11 ist vorzugsweise kreis- oder ellipsenabschnittförmig, insbesondere halbkreisförmig oder halbellipsenförmig ausgebildet und liegt mit seiner geraden Kante an dem Speiseanschlussbereich 9 des Antennenelementes 3 an. Das Speiseverbindungselement 11 kontaktiert jedoch nicht die Massefläche 2, sondern weist an der gekrümmten Kante, vorzugsweise an seinem der Massefläche 2 zugewandten Ende eine Kontaktstelle 12 auf, über die das Sendesignal dem Antennenelement 3 zugeführt wird. Die halbkreisförmige bzw. halbellipsenförmige Ausgestaltung des Speiseverbindungselementes 11 ermöglicht eine angepasste Stromverteilung in dem Antennenelement 3. Eine Kontaktierung des Multiband-Rundstrahlers 1 erfolgt beispielsweise durch Anschließen eines nicht gezeigten Koaxialkabels im Bereich des Speiseverbindungselementes 11, so dass der Innenleiter des Koaxialkabels mit der Kontaktstelle 12 und der Außenleiter mit der Massefläche 2 verbunden wird. Der erste und der zweite Flächenstrahler 4, 5 können einen quadratischen oder rechteckförmigen Querschnitt aufweisen. Im vorliegenden Ausführungsbeispiel ist der erste Flächenstrahler 4 im Wesentlichen rechteckförmig ausgebildet, wobei an dessen kürzeren Kanten die Verbindungselemente 7 angeordnet sind. Die VerbindungselementeArranged on the feed connection region 9 is a feed connection element 11, which protrudes in particular at right angles from the antenna element 3 in the direction of the ground surface 2, so that the feed connection element 11 is arranged between the antenna element 3 and the ground surface 2. The feed connection element 11 is preferably circular or elliptical section-shaped, in particular semicircular or semi-elliptical, and lies with its straight edge against the feed connection region 9 of the antenna element 3. However, the feed connector 11 does not contact the ground plane 2, but has at the curved edge, preferably at its the ground surface 2 end facing a contact point 12, via which the transmission signal is supplied to the antenna element 3. The semicircular or semi-elliptical configuration of the feed connection element 11 enables an adapted current distribution in the antenna element 3. Contacting of the multiband omnidirectional device 1 takes place, for example, by connecting a coaxial cable, not shown, in the area of the feed connection element 11, so that the inner conductor of the coaxial cable with the contact point 12 and the outer conductor is connected to the ground plane 2.
