Description

Die Erfindung bezieht sich auf eine Mehrantennenanordnung mit mehreren Antennen für Antennendiversity vorzugsweise für den Empfang im Bereich der Meterwellen (UKW), z.B. im Kraftfahrzeug, gemäß dem Oberbegriff des Anspruches 1. Solche Mehrantennenanordnungen werden verwendet für den Empfang frequenzmodulierter Signale, wie z.B. des UKW-Rundfunks.The invention relates to a multi-antenna arrangement with a plurality of antennas for antenna diversity, preferably for reception in the range of the meter waves (VHF), e.g. in a motor vehicle, according to the preamble of claim 1. Such multi-antenna arrangements are used for receiving frequency-modulated signals, such as of FM radio.

Für Antennendiversitysysteme, die eine deutliche Verbesserung des UKW-Empfangs im Kraftfahrzeug ermöglichen, sind mindestens zwei Antennen erforderlich.Antenna diversity systems that enable a significant improvement in VHF reception in the motor vehicle require at least two antennas.

Unter fahrzeugspezifischen Gesichtspunkten sind diese Antennen vorzugsweise so zu gestalten, daß sie in die Fahrzeugkarosserie integriert sind, was optimal in der Form von Scheibenantennen erfolgt. Neben der Frontscheibe, die aber in vielen Fahrzeugen wegen des dort vorhandenen hohen Störpegels durch die im Frontbereich der Fahrzeuge angeordneten Aggregate für die Realisierung von Antennen ausscheidet, ist die Fahrzeugheckscheibe geeignet zur Realisierung von Fahrzeugantennen.From a vehicle-specific point of view, these antennas should preferably be designed in such a way that they are integrated into the vehicle body, which takes place optimally in the form of window antennas. In addition to the windscreen, which is eliminated in many vehicles due to the high level of interference present there through the units arranged in the front area of the vehicles for the realization of antennas, the vehicle rear window is suitable for realizing vehicle antennas.

Die Realisierung von Fahrzeugantennen in der Hekcscheibe muß auf das dort vorhandene Heizfeld Rücksicht nehmen, dessen Ausführung und Abmessungen unter fahrzeugspezifischen und stilistischen Gesichtspunkten vorgegeben sind.The implementation of vehicle antennas in the rear window must take into account the heating field there, the design and dimensions of which are specified from a vehicle-specific and stylistic point of view.

Eine Anordnung für zwei Antennen in der Fahrzeugheckscheibe für die Anwendung in Diversitysystemen wird von EP 0065263 vorgeschlagen. Bei dieser Anordnung wird im vom Heizfeld nicht bedeckten Bereich der Scheibe eine Hauptantenne eingebaut.
Eine derartige Anordnung weist den Nachteil auf, daß das Diversitysystem auf zwei UKW-Antennen beschränkt ist. Sind die Signale von beiden Antennen gleichzeitig gestört, so ist der Empfang unbefriedigend und die empfundene Störung wird dadurch erheblich vergrößert, daß das Diversitysystem während dieser Zeit fortwährend zwischen den beiden Antennen umschaltet und das in der Praxis unvermeidbare Schaltgeräusch sich der Empfangsstörung zusätzlich überlagert. Dieser Fall ist in der Praxis häufig gegeben. Es ist deshalb notwendig, die Anzahl der für Antennendiversity zur Verfügung stehenden Antennen zu erhöhen. Andererseits ist die Verwendung zusätzlicher Antennen am Fahrzeug außerhalb des Fensters kostenintensiv.An arrangement for two antennas in the vehicle rear window for use in diversity systems is proposed by EP 0065263. With this arrangement, a main antenna is installed in the area of the pane not covered by the heating field.
Such an arrangement has the disadvantage that Diversity system is limited to two FM antennas. If the signals from both antennas are disturbed at the same time, the reception is unsatisfactory and the perceived interference is considerably increased by the fact that the diversity system continuously switches between the two antennas during this time and the switching noise that is inevitable in practice is also superimposed on the reception interference. This is often the case in practice. It is therefore necessary to increase the number of antennas available for antenna diversity. On the other hand, the use of additional antennas on the vehicle outside the window is expensive.

Der Erfindung liegt deshalb die Aufgabe zu Grunde, in einer Fensterscheibe eines Fahrzeugs unter Einbeziehung des Heizfelds mit vorgegebener Form eine Mehrantennenanordnung für Antennendiversity vorzugsweise für den Empfang im Bereich der Meterwellen (UKW) mit mehr als zwei Antennen auszubilden, wobei die mittlere Empfangsqualität mit jeder Einzelantenne möglichst gut ist und die Anzahl der Störungen, die in den Signalen der verschiedenen Antennen gleichzeitig auftreten, möglichst gering ist.The invention is therefore based on the object of forming a multi-antenna arrangement for antenna diversity, preferably for reception in the range of meter waves (VHF) with more than two antennas in a window pane of a vehicle, including the heating field with a predetermined shape, the average reception quality with each individual antenna is as good as possible and the number of interferences that occur simultaneously in the signals of the different antennas is as small as possible.

Diese Aufgabe wird erfindungsgemäß bei einer Diversityantennen-Anordnung der eingangs genannten Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Eine HF-mäßige Entkopplung im Sinne des Anspruches 1 liegt vor, wenn die Empfangssignale der Antennen, insbesondere im Hinblick auf Empfangsstörungen, wie z.B. Einbrüche des HF-Pegels, unterschiedlich sind.This object is achieved according to the invention in a diversity antenna arrangement of the type mentioned at the outset by the characterizing features of claim 1. RF decoupling within the meaning of claim 1 is present when the received signals of the antennas, in particular with regard to reception interference, such as e.g. Dips in the RF level are different.

Erfindungsgemäße Ausführungsbeispiele sind in den angegebenen Zeichnungen dargestellt und werden im folgenden näher beschrieben. Im einzelnen zeigt:

  • Fig. 1 Mehrantennenanordnung nach der Erfindung mit einer weiteren UKW-Antenne links oben im Fensterfeld, zwei aus dem Heizfeld gebildeten UKW-Antennen und einer Antenne für den LMK-Empfang (rechts oben).
  • Fig. 2 Mehrantennenanordnung nach der Erfindung wie Fig. 1, jedoch mit einer zusätzlichen aus dem Heizfeld gebildeten UKW-Antenne.
  • Fig. 3 Mehrantennenanordnung wie in Fig. 1, jedoch mit einem Faltmonopol für die Ausbildung der weiteren UKW-Antenne (links oben).
  • Fig. 4 Mehrantennenanordnung nach der Erfindung mit zwei weiteren UKW-Antennen unterhalb des Heizfeldes, von denen die eine als Faltmonopol (5c) und die andere als Drahtmonopol (5d) ausgeführt ist. Rechts unten im Fensterfeld ist beispielhaft eine Antenne für den LMK-Empfang angebracht.
  • Fig. 5 Mehrantennenanordnung nach der Erfindung mit einer weiteren UKW-Antenne oberhalb des Heizfeldes, deren Antennenleiter (5c) auch als Teil einer LMK-Antenne verwendet ist.
Embodiments according to the invention are shown in the specified drawings and are described in more detail below. In detail shows:
  • Fig. 1 multi-antenna arrangement according to the invention with a further FM antenna in the upper left corner of the window field, two FM antennas formed from the heating field and an antenna for LMK reception (top right).
  • Fig. 2 multi-antenna arrangement according to the invention as Fig. 1, but with an additional FM antenna formed from the heating field.
  • Fig. 3 multi-antenna arrangement as in Fig. 1, but with a folding monopoly for the formation of the further FM antenna (top left).
  • Fig. 4 multi-antenna arrangement according to the invention with two further FM antennas below the heating field, one of which is designed as a folding monopoly (5c) and the other as a wire monopoly (5d). An antenna for LMK reception is attached as an example at the bottom right of the window field.
  • Fig. 5 multi-antenna arrangement according to the invention with a further FM antenna above the heating field, the antenna conductor (5c) is also used as part of an LMK antenna.

In Fig. 1 ist eine von einem metallischen Rahmen, der im folgenden als Masse bezeichnet wird, umgebene Fensterscheibe dargestellt. Die Heizfläche wird für die Bildung von mindestens zwei UKW-Antennen herangezogen. Durch Wahl geeigneter Anschlußklemmenpaare, die jeweils aus dem Leiterteil-Anschlußpunkt (5a,b) und einem benachbarten Massepunkt auf dem Rahmen gebildet sind, lassen sich UKW-Antennen herstellen, deren Signale weitgehend unabhängig voneinander sind. In den nicht mit Leitern bedeckten Teilflächen des Fensters können erfindungsgemäß weitere UKW-Antennen angebracht werden, deren Empfangssignale ebenfalls insbesondere hinsichtlich der zu vermeidenden Störungen von den übrigen UKW-Antennen unterschiedlich sind. Im Beispiel der Fig. 1 ist die linke Hälfte des Fensters oberhalb der Heizflächen mit einem UKW-Monopol (5c) belegt, der als parallel geführte Leiter, die am Anschlußpunkt zusammengefaßt sind, ausgeführt ist. Die Abmessungen dieses Monopols sind unter Nutzung des zur Verfügung stehenden Raumes so gewählt, daß die mittlere Empfangsleistung einen möglichst guten Wert annimmt. Bei den üblichen Fahrzeugabmessungen, deren Breite im UKW-Bereich ungefähr eine halbe Wellenlänge beträgt, lassen sich somit Monopole mit einer günstigen Länge von einer viertel Wellenlänge realisieren. Die Abstände vom Rahmen und von den Heizfeldern werden nach bekannten Gesichtspunkten günstig eingestellt. Im Beispiel der Fig. 1 wird der Raum oberhalb des Heizfeldes im rechten Fensterteil für die Gestaltung einer LMK-Antenne nach bekannten Gesichtspunkten verwendet. Das Heizfeld stellt im allgemeinen für den LMK-Frequenzbereich, ebenso wie der Fensterrahmen, hochfrequenzmäßig eine Masse dar. Um für LMK einen guten Empfang zu gewährleisten, werden hinsichtlich der Dimensionierung der LMK-Antenne die Abmessungen nach den in DOS-P 34 10 415.1 dargelegten Gesichtspunkten eingestellt.1 shows a window pane surrounded by a metallic frame, which is referred to below as the mass. The heating surface is used for the formation of at least two FM antennas. By selecting suitable pairs of terminals, each of which is formed from the conductor part connection point (5a, b) and an adjacent earth point on the frame, can be Manufacture FM antennas whose signals are largely independent of each other. According to the invention, additional VHF antennas can be attached in the partial areas of the window that are not covered with conductors, the reception signals of which are also different from the other VHF antennas, particularly with regard to the interference to be avoided. In the example in FIG. 1, the left half of the window above the heating surfaces is covered with a VHF monopoly (5c) which is designed as a parallel conductor that is combined at the connection point. The dimensions of this monopoly are chosen using the available space so that the average reception power takes on the best possible value. With the usual vehicle dimensions, the width of which in the VHF range is approximately half a wavelength, monopoles with a favorable length of a quarter wavelength can thus be realized. The distances from the frame and from the heating fields are set favorably according to known aspects. In the example in FIG. 1, the space above the heating field in the right part of the window is used for the design of an LMK antenna according to known aspects. The heating field generally represents a mass for the LMK frequency range, just like the window frame, in terms of radio frequency. In order to ensure good reception for LMK, the dimensions according to the dimensions of the LMK antenna are set out in DOS-P 34 10 415.1 Viewpoints set.
