Description

Die Erfindung betrifft eine Antenne für Mobilfunk gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1,The invention relates to an antenna for mobile radio according to the features of the preamble of claim 1,

Aus der DE 199 22 699 A1 ist eine Antenne, vorzugsweise eine Fahrzeugsantenne für Mobilfunk, bekannt. Bei dieser Antenne sind als Strahlungsmittel Vertikalstrahler vorhanden, die auf einer Massefläche angeordnet und über eine Impedanztransformationsleitung miteinander verbunden sind. Aufgrund der Abstimmung (insbesondere Länge) der Vertikalstrahler und der Impedanztransformationsleitung für den vorgesehenen Frequenzbereich, insbesondere in dem Mobilfunkbereich von 0,8 bis 2,2 GHz, weist diese bekannte Antenne vorgegebene Längs- und Höhenmaße auf. Da diese Antenne unterhalb einer Heckscheibe eines Fahrzeuges integriert wird, benötigt sie aufgrund ihrer geometrischen Abmessung einen großen Bauraum, der entweder nicht zur Verfügung steht oder durch den Innenraum des Fahrzeuges in unerwünschter Weise verkleinert wird. Ein weiterer Nachteil besteht darin, daß ein Koaxialkabel zur Signalübertrag direkt an der Massefläche angelötet ist, wobei der Innenleiter des Koaxialkabels mit der Impedanztransformationsleitung verbunden wird. Dadurch entsteht ein aufwendiger Aufbau, der Insbesondere den Nachteil hat, daß vor dem Einbau der Antenne diese einen Kabelschwanz aufweist, der Probleme beim Handling der vorgefertigten Antennen vor deren Einbau bereitet.From the DE 199 22 699 A1 is an antenna, preferably a vehicle antenna for mobile radio, known. In this antenna are provided as a radiation means vertical radiator, which are arranged on a ground plane and connected to each other via an impedance transformation line. Due to the tuning (in particular length) of the vertical radiator and the impedance transformation line for the intended frequency range, in particular in the mobile radio range of 0.8 to 2.2 GHz, this known antenna has predetermined longitudinal and vertical dimensions. Since this antenna is integrated below a rear window of a vehicle, it requires due to their geometric dimension of a large space that either is not available or is reduced by the interior of the vehicle in an undesirable manner. Another disadvantage is that a coaxial cable is soldered to the signal transfer directly to the ground plane, wherein the inner conductor of the coaxial cable is connected to the impedance transformation line. This results in a complex structure, which has the particular disadvantage that prior to installation of the antenna, this has a cable tail, which prepares problems in handling the prefabricated antennas prior to their installation.

Aus der US 6,008,770 ist eine Antenne mit Strahlungsmitteln zum Empfangen und Senden von Hochfrequenzsignalen bekannt, wobei als Strahlungsmittel leitfähige Bereiche auf einer Platine vorgesehen sind, die von zumindest einem längs verlaufenden Schlitz voneinander getrennt sind. Der längs verlaufende Schlitz ist symmetrisch zu einer Längsachse der Antenne ausgebildet, so dass die beiden von dem Schlitz getrennten leitfähigen Bereiche ebenfalls symmetrisch gestaltet sind.From the US 6,008,770 For example, an antenna with radiation means for receiving and transmitting high-frequency signals is known, wherein as radiation means conductive areas are provided on a circuit board which are separated from each other by at least one longitudinal slot. The longitudinal slot is formed symmetrically to a longitudinal axis of the antenna, so that the two separated from the slot conductive areas are also designed symmetrically.

Die FR 1.091.358 und die EP 0 531 800 A1 zeigen Antennen, bei denen elektrisch leitfähige Bereiche als Strahlungsmittel eingesetzt werden, wobei die elektrisch leitfähigen Bereiche asymmetrisch zu seiner Längsachse von einem Schlitz getrennt werden.The FR 1.091.358 and the EP 0 531 800 A1 show antennas in which electrically conductive portions are used as the radiation means, wherein the electrically conductive portions are separated from a slot asymmetrically to its longitudinal axis.

Aus der gattungsblldenden US 4,425,549 Ist eine Vorrichtung zum Aufspüren von Radiosignalen mit Strohlungsmitteln bekannt, wobei als Strahlungsmittel leitfähige Bereiche, die von zumindest einem längs verlaufenden Schlitz voneinander getrennt sind, auf einer Platine vorgesehen sind, wobei die elektrisch leitfähigen Bereiche in die Richtung, in die keine Einstrahlung stattfinden soll, durch einen in seinen Endbereichen offenen Gehäusekörper, der an Randbereichen der Platine angeordnet ist und der aus einem abgewinkelten Blech besteht, abgeschirmt sind. Ein Fußpunkt der Vorrichtung ist etwa Im Mittenbereich eines Trennelementes, der den Gehäusekörper in zwei Hohlräume trennt, angeordnet.From the generous US 4,425,549 Is a device for detecting radio signals with Strohlungsmitteln known, wherein as radiation means conductive areas, which are separated from each other by at least one longitudinal slot, are provided on a circuit board, wherein the electrically conductive areas in the direction in which no radiation is to take place, by a housing body which is open in its end regions and which is arranged at edge regions of the printed circuit board and which consists of an angled sheet metal, are shielded. A foot point of the device is arranged approximately in the middle region of a separating element which separates the housing body into two cavities.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Antenne, Insbesondere eine Fahrzeugantenne für Mobilfunk, bereitzustellen, mit der die eingangs geschilderten Nachteile vermieden werden. Diese Antenne soll unter Berücksichtigung des eingeschränkten Bauraums in einem Fahrzeug einfach montiert werden können und in dem Fahrzeug die geforderten Sende- und Empfangselgenschaften aufweisen.The invention is therefore based on the object, an antenna, in particular a vehicle antenna for mobile, to provide, with the above-described disadvantages are avoided. Taking into account the limited installation space, this antenna should be able to be easily mounted in a vehicle and have the required transmission and reception characteristics in the vehicle.

Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst.This object is solved by the features of claim 1.

Bei der erfindungsgemäßen Antenne wird als Strahlungsmittel ein beidseitig offener und längsgeschlitzter leitfähiger Bereich in mehreren Frequenzbereichen zum Strahlen angeregt. Aufgrund dessen Ist es möglich, daß die Antenne bei gleichen Eigenschaften kompakter baut, insbesondere wesentlicher kürzer (etwa um die Hälfte) und flacher ist. Damit kann der unter der Heckscheibe bzw. am Dachflansch des Fahrzeuges vorhandene Bauraum wesentlich besser und sparsamer ausgenutzt werden. Je nach Größe des Frequenzbereiches bzw. in Abhängigkeit der zu sendenden oder zu empfangenden Frequenzen entspricht die Länge der Antenne in etwa einem Drittel der Wellenlänge der tiefsten Frequenz. Weiterhin bilden die längsgeschlitzten leitfähigen Bereiche zusammen einen spitz zulaufenden Schlitz. Damit wird auf einfache Art und Weise ein flachbauender Vertikalstrahler für den oder die erforderlichen Frequenzbereich(e) zur Verfügung gestellt. Außerdem sind die Bereiche in die Richtung, in die keine Einstrahlung stattfinden soll, durch einen Gehäusekörper aus Blech abgeschirmt. Durch diesen Gehäusekörper aus Metall wird verhindert, daß eine Einstrahlung in den Innenraum des Fahrzeuges erfolgt. Je nach Abmessung des Gehäusekörpers, der sich zumindest über den Bereich der Platine erstreckt, aber auch größer oder kleiner sein kann, wird zumindest eine wesentliche Reduzierung der Einstrahlung in den Innenraum des Fahrzeuges realisiert.In the case of the antenna according to the invention, a conductive region which is open on both sides and longitudinally slit in a plurality of frequency ranges is excited to radiate as the radiation means. Because of this, it is possible for the antenna to be more compact with the same characteristics, in particular significantly shorter (about half) and shallower. Thus, the existing space under the rear window or on the roof flange of the vehicle space can be used much better and more economical. Depending on the size of the frequency range or as a function of the frequencies to be transmitted or received, the length of the antenna corresponds to approximately one third the wavelength of the lowest frequency. Furthermore, the longitudinally slotted conductive areas together form a tapered slot. Thus, a flat-building vertical radiator for the required frequency range (s) is provided in a simple manner. In addition, the areas in the direction in which no radiation is to take place are shielded by a housing body made of sheet metal. By this housing body made of metal prevents radiation from entering the interior of the vehicle. Depending on the dimension of the housing body, which extends at least over the area of the circuit board, but may also be larger or smaller, at least a substantial reduction of the radiation into the interior of the vehicle is realized.

Weiterhin geht von dem spitz zulaufenden Schlitz ein weiterer, insbesondere etwa In der Mitte, abzweigender Schlitz aus, der die längsgeschlitzen leitfähigen Bereiche voneinander trennt. Je nach Ausführung, insbesondere Breite und Länge des abgewinkelten Schlitzes, kann die Impedanz der Antenne In weiten oder auch zusätzlichen Bereichen angepaßt werden. Zur optimalen Impedenzanpassung und auch zur optimalen Flächenausnutzung ist dabei der von dem spitz zulaufenden Schlitz ausgehende Schenkel des abgewinkelten Schlitzes kürzer als der sich daran anschließende Schlitzbereich.Furthermore, from the tapered slot another, in particular approximately in the middle, branching off slot, which separates the longitudinal slit conductive areas from each other. Depending on the design, in particular width and length of the angled slot, the impedance of the antenna can be adapted in wide or additional areas. For optimum impedance matching and also for optimum area utilization, the leg of the angled slot extending from the tapered slot is shorter than the adjoining slot area.

In Weiterbildung der Erfindung weist der längsgeachlitzte leitfähige Bereich in einem Teilbereich einen Doppelknick auf. Der beispielsweise etwa Trichterform aufweisende doppelt geknickte Schlitz gewährleistet eine große Breitbandigkeit und macht damit den Strahler robust gegenüber Einbautoleranzen.In a development of the invention, the longitudinally diffused conductive region has a double bend in a partial region. The example about funnel shape having doubly kinked slot ensures a large broadband and thus makes the spotlight robust against installation tolerances.

In Weiterbildung der Erfindung sind die längsgeschlitzten leitfähigen Bereiche als Kupferfläche auf einer Platine angeordnet. Dadurch steht zum einen ein preisgünstiges Material zur Verfügung, um die Vertikalstrahler der Antenne zu fertigen. Andererseits ist es durch an sich bekannte Verfahren (z.B. Ätzverfahren) möglich, die Bereiche aus Kupfer auf der Platine zu belassen, während der wenigstens eine Schlitz, insbesondere beide Schlitze, durch Wegätzen der entsprechenden Kupferbereiche hergestellt werden können. Aufgrund dieses Verfahrens ist es möglich, die Form der Bereiche, ebenso wie die Form der Schlitze, In weiten, erforderlichen Flächengebungen zu beeinflussen.In a further development of the invention, the longitudinally slotted conductive regions are arranged as a copper surface on a circuit board. As a result, on the one hand an inexpensive material is available to manufacture the vertical radiator of the antenna. On the other hand, it is possible by methods known per se (eg, etching method) to leave the areas of copper on the board, while the at least one slot, in particular both slots, can be produced by etching away the corresponding copper areas. By virtue of this method it is possible to influence the shape of the areas, as well as the shape of the slots, in wide, required areas.

In Weiterbildung der Erfindung ist der abzweigende Schlitz so ausgeführt, daß kein Gleichstromkurzschluß am Fußpunkt der Antenne auftritt. Aufgrund dessen kann die Antenne vor ihrem Einbau elektrisch auf ihre Funktionstüchtigkeit oder auf vorhandene Fehler geprüft werden. Durch die Vermeidung des Glelchstromkurzschlusses muss nur ein einfacher Prüfwiderstand im Speisepunkt parallel geschaltet werden. Der für konventionelle Schlitzstrahler notwendige Koppelkondensator kann entfallen. Dies vereinfacht den Aufbau und senkt die Kosten.In development of the invention, the branching slot is designed so that no DC short circuit occurs at the base of the antenna. Because of this, the antenna can be electrically tested for its functionality or for existing faults before being installed. By avoiding the short-circuit current short circuit, only a simple test resistor in the feed point needs to be connected in parallel. The necessary for conventional slot radiator coupling capacitor can be omitted. This simplifies the construction and reduces the costs.

Weiterhin ist In dem Fußpunkt der Antenne auf der Platine als Kontaktpartner ein Stecker angeordnet. Dadurch kann mit Herstellung der Antenne der Kontaktpartner schon auf der Platine vorgesehen worden, ohne daß zu diesem Zeitpunkt ein Kabel erforderlich ist. Zum Test der Antenne kann ein solches Kabel über den Kontaklpertner vorübergehend angeschlossen werden. Nach Testablauf kann das Kabel wieder entfernt werden, so daß der Transport und die Lagerung der Antenne bis zu ihrem endgültigen Einbau vereinfacht ist. Erst mit oder nach Einbau der Antenne in das Fahrzeug findet da eine entsprechende Verkabelung statt.Furthermore, a plug is arranged in the base of the antenna on the board as a contact partner. As a result, with the manufacture of the antenna, the contact partner has already been provided on the board, without a cable being required at this time. To test the antenna, such a cable can be temporarily connected via the contact person. After the test, the cable can be removed again, so that the transport and storage of the antenna is simplified to its final installation. Only with or after installation of the antenna in the vehicle there is a corresponding wiring instead.

Ein Ausführungsbeispiel einer Antenne und deren Einbau ist im Folgenden beschrleben und anhand der Figuren erläutert. Dabei ist die Erfindung jedoch nicht auf die gezeigten Ausführungsbeispiele beschränkt.An embodiment of an antenna and its installation will be described below and explained with reference to the figures. However, the invention is not limited to the embodiments shown.

Figur 1 zeigt eine Antenne 1 zum Empfangen und Senden von Hochfrequenzsignalen, insbesondere in den Mobllfunkbereichen AMPS, GSM 900/18000, PCS, UMTS und dergleichen. Bei der gezeigten Antenne 1 handelt es sich insbesondere um eine Fahrzeugantenne, wobei auch andere Anwendungsgebiete, auch statische Einsätze, denkbar sind. FIG. 1 shows an antenna 1 for receiving and transmitting high-frequency signals, in particular in the Mobfunk ranges AMPS, GSM 900/18000, PCS, UMTS and the like. In the illustrated antenna 1 is in particular a vehicle antenna, with other applications, including static operations, are conceivable.

Die Antenne 1 weist einen metallenen Gehäusekörper auf, der aus einem mehrfach abgewinkelten Blech 2 besteht. Ein solches abgewinkeltes Blech 2 ist einerseits hinsichtlich der Materialkosten günstig, andererseits ist es schnell und einfach zu fertigen. Dies beeinflußt im positiven Sinne die Herstellung der erfindungsgemäßen Antenne 1. Durch die entsprechende Abwinkelung des Bleches 2 sind zwei parallele und beabstandete Schenkel entstanden, zwischen denen eine Platine 3 angeordnet ist. Die Platine 3 hat in an sich bekannter Weise eine aus einem nicht leitenden Material bestehende Grundfläche. Auf dieser Grundfläche der Platine 3 sind mehrere leitfähige Bereiche 4 bis 6 angeordnet, die beispielsweise dadurch hergestellt werden, daß die späteren leitfähigen Bereiche 4 bis 6 abgedeckt werden und die nicht abgedeckten Zwischenbereiche weggeätzt werden. Diese wegzuätzende Bereiche bilden anschließend zumindest einen ersten Schlitz 7, der einerseits durch die Formgebung des Bereiches 4 und andererseits durch die Formgebung der Bereiche 5 und 6 entsteht. Weiterhin ist ausgehend von dem ersten Schlitz 7 zur Anpassung der Impedanz der Antenne 1 ein zweiter Schlitz 8 vorhanden, der wiederum die beiden Bereiche 5 und 6 voneinander trennt. Entfällt der zweite Schlitz 8, bilden die beiden Bereiche 5 und 6 einen durchgehenden Bereich, der zweite Schlitz 8 geht etwa von der Mitte des ersten Schlitzes 7 aus und erstreckt sich zunächst rechtwinklig von diesem über ein kurzes Stück, während sich der längere Teil des zweiten Schlitzes 8 in etwa parallel zu dem ersten Schlitz 7 befindet.The antenna 1 has a metal housing body, which consists of a multi-angled sheet 2. Such an angled sheet 2 is favorable on the one hand in terms of material costs, on the other hand, it is quick and easy to manufacture. This affects in a positive sense the production of the antenna according to the invention 1. By the corresponding bending of the sheet 2, two parallel and spaced legs have arisen, between which a circuit board 3 is arranged. The board 3 has in a conventional manner one consisting of a non-conductive material base. On this base of the board 3, a plurality of conductive portions 4 to 6 are arranged, which are prepared, for example, that the later conductive areas 4 to 6 are covered and the uncovered intermediate areas are etched away. These regions to be etched away subsequently form at least one first slot 7 which, on the one hand, results from the shaping of the region 4 and, on the other hand, from the shaping of the regions 5 and 6. Furthermore, starting from the first slot 7 for adjusting the impedance of the antenna 1, a second slot 8 is present, which in turn separates the two areas 5 and 6 from each other. If the second slot 8 is omitted, the two areas 5 and 6 form a continuous area, the second slot 8 extends approximately from the center of the first slot 7 and at first extends at right angles therefrom for a short distance, while the longer part of the second Slot 8 is located approximately parallel to the first slot 7.

Bei der in der Figur 1 gezeigten Ausführungsform der Antenne 1 ist der leitfähige Bereich 5 mit einem Doppelknick 9 versehen. An einem Fußpunkt 10 der Antenne 1 befindet sich ein Kontaktpartner, insbesondere ein Stecker 11, an welchem ein Koaxialkabel zur Speisung der Antenne 1 einsteckbar ist. Um die Platine 3 an dem Gehäusekörper, Insbesondere dem abgewinkelten Blech 2, befestigen können, weisen die parallel zu einander beabstandeten Schenkel des Bleches 2 mehrere Stanz- Biegeberelche 12 auf, über die die Platine 3 an dem Gehäusegrundkörper festgelegt wird. Solche Stanz-Biegebreiche 12 haben den Vorteil, daß sie einfach herzustellen sind und damit die Platine 3 schnell an dem Gehäusekörper 2 festgelegt werden kann.When in the FIG. 1 shown embodiment of the antenna 1, the conductive region 5 is provided with a double kink 9. At a base 10 of the antenna 1 is a contact partner, in particular a plug 11, to which a coaxial cable for feeding the antenna 1 can be inserted. In order to fix the board 3 to the housing body, in particular the angled sheet 2, have the parallel to each other spaced legs of the sheet 2 a plurality of punching Biegeberelche 12, via which the board 3 is fixed to the housing base. Such punching bending areas 12 have the advantage that they are easy to manufacture and thus the board 3 can be quickly fixed to the housing body 2.

Figur 2 zeigt die In Figur 1 in einer dreidimensionalen Ansicht dargestellte Antenne 1 Im Schnitt an ihrem Einbauort. Im Endbereich eines Dachflansches 13 eines nicht weiter dargestellten Fahrzeuges schließt sich die Heckscheibe 14 an, die mittels einer Verklebung (Kleberaupe 15) an dem Dachflansch 13 befestigt wird. In dem Bereich zwischen der Scheibe 14 und einer Innenverkleidung 16 (Dachhimmel) befindet sich der Einbauort der Antenne 1, der aufgrund der erfindungsgemäßen Ausgestaltung der Antenne 1 besonders flach gehalten werden kann, FIG. 2 shows the In FIG. 1 in a three-dimensional view illustrated antenna 1 in section at their installation. In the end of a roof flange 13 not one further illustrated vehicle is followed by the rear window 14, which is attached by means of a bond (adhesive bead 15) on the roof flange 13. In the area between the pane 14 and an interior trim 16 (headliner) is the installation location of the antenna 1, which can be kept particularly flat due to the inventive design of the antenna 1,

Die Antenne, Insbesondere die Fahrzeugantenne für Mobilfunk, ist somit zusammenfassend als strahlender offener Hohlraumresonator mit besonders ausgeführtem Breitbandschlitz ausgebildet, um eine möglichst kompakte, insbesondere flache und kurze Bauweise zu erzielen.The antenna, in particular the vehicle antenna for mobile communications, is thus in summary designed as a radiating open cavity resonator with a specially designed broadband slot in order to achieve the most compact, particularly flat and short design possible.
