Abstract
Description
Die Erfindung betrifft eine Antennenanordnung in einem Kraftfahrzeug, zum Beispiel für ein Diebstahlschutzsystem. Eine solche Antennenanordnung weist zumindest eine Antenne mit einer Spule auf. Ferner weist eine solche Antennenanordnung eine Sende- und/oder Empfangseinheit auf, die über zumindest eine Leitung mit der Antenne verbunden ist.The The invention relates to an antenna arrangement in a motor vehicle, for example for an anti-theft system. Such an antenna arrangement has at least an antenna with a coil on. Furthermore, such an antenna arrangement has a Transmitting and / or receiving unit, via at least one line connected to the antenna.
Antennenanordnungen
der eingangs genannten Art sind beispielsweise aus der Druckschrift
Eine hohe Sendeleistung der Antennenanordnung führt jedoch zu einem höheren Stromverbrauch der Anordnung. Ein weiterer Nachteil liegt darin, dass die elektromagnetische Verträglichkeit des Kraftfahrzeugs insgesamt beeinflusst wird. Grundsätzlich werden daher geringe Sendeleistungen angestrebt.A high transmission power of the antenna arrangement, however, leads to a higher power consumption the arrangement. Another disadvantage is that the electromagnetic compatibility of the motor vehicle as a whole. Basically therefore, low transmission powers sought.
VORTEILE DER ERFINDUNGADVANTAGES OF INVENTION
Hier setzt die vorliegende Erfindung an. Der Erfindung liegt die Aufgabe zugrunde, eine Antennenanordnung der eingangs genannten Art so zu verbessern, dass einerseits keine toten Bereiche bei einer Verwendung einer Antennenanordnung in einem Kraftfahrzeug entstehen und andererseits die Sendeleistung so weit wie möglich minimiert werden kann.Here uses the present invention. The invention is the task based, an antenna arrangement of the type mentioned so too improve, on the one hand, no dead areas when used an antenna arrangement in a motor vehicle arise and on the other hand the transmission power as much as possible can be minimized.
Diese Aufgabe wird durch eine Antennenanordnung gemäß Anspruch 1 gelöst. Demnach umfasst eine erfindungsgemäße Antennenanordnung neben den eingangs genannten Merkmalen zumindest eine Schleife in der Leitung von der Antenne zur Sende- und/oder Empfangseinheit. Diese Schleife wirkt als weitere Antenne und sendet das über die Leitung geführt Signal in die unmittelbare Umgebung aus und/oder empfängt Signale, die in unmittelbarer Umgebung der Schleife empfangbar sind. Im physikalischen Sinne weist die Antennenanordnung damit zwei Antennen auf, zum einen das als separates Bauteil und speziell für die Sende- und/oder Empfangsfunktion ausgestaltete Antenne, zum anderen die Schleife des Leiters, die die Funktion einer Antenne hat, aber nicht als separates Bauteil ausgestaltet ist. Eine Antennenanordnung gemäß dem Stand der Technik muss für die Umsetzung der Erfindung nur minimal verändert werden. Lediglich ein Leiter zwischen der Sende- und Empfangseinheit und der eigentlichen Antenne muss zu einer Schleife gelegt werden. Ist diese Schleife in einem von der eigentlichen Antenne nicht erreichten Bereich angeordnet, so kann dieser tote Bereich von der Antenne erfasst werden. Die Sendeleistung der Antennenanordnung muss nicht mehr so stark erhöht werden, dass die eigentliche Antenne den gesamten Innenraum des Kraftfahrzeugs erreicht.These The object is achieved by an antenna arrangement according to claim 1. Therefore includes an antenna arrangement according to the invention in addition the features mentioned at least one loop in the Cable from the antenna to the transmitting and / or receiving unit. These Loop acts as another antenna and sends it over the line guided Signal into the immediate environment and / or receive signals, which are receivable in the immediate vicinity of the loop. In the physical Senses, the antenna assembly so that two antennas, on the one hand as a separate component and especially for the transmitting and / or receiving function designed antenna, on the other hand, the loop of the conductor, the has the function of an antenna, but not as a separate component is designed. An antenna arrangement according to the prior art must for the Implementation of the invention can be changed only minimally. Only one Head between the transmitting and receiving unit and the actual Antenna must be put to a loop. Is this loop arranged in an area not reached by the actual antenna, so This dead band can be detected by the antenna. The transmission power the antenna array does not have to be increased so much that the actual antenna covers the entire interior of the motor vehicle reached.
Die Schleife einer erfindungsgemäßen Antennenanordnung kann zumindest in einem Abschnitt mäanderförmig ausgeführt sein. Durch die mäanderförmige Ausführung der Schleife oder durch mehrere Schleifen kann der Wirkungsgrad der durch die Schleife gebildeten Antenne vergrößert werden.The Loop of an antenna arrangement according to the invention can be executed meandering at least in one section. Due to the meandering design of Loop or through multiple loops, the efficiency of the enlarged by the loop formed by the loop antenna.
Die Antenne einer erfindungsgemäßen Antennenanordnung kann einen Ferritkern aufweisen.The Antenna of an antenna arrangement according to the invention may have a ferrite core.
Die erfindungsgemäße Antennenanordnung kann in einem erfindungsgemäßen Fahrzeug mit einer solchen Antennenanordnung angeordnet sein. Die Schleife des Leiters kann dann in oder auf einem Teil einer Innenraumverkleidung eines Kraftfahrzeugs angebracht sein. Die Schleife kann zum Beispiel auf dem Teil der Innenraumverkleidung, es kann sich hierbei zum Beispiel um die Hutablage handeln, aufgeklebt sein. Die Schleife kann als Folienleiter oder als Rundleiter ausgeführt sein.The Antenna arrangement according to the invention can in a vehicle according to the invention be arranged with such an antenna arrangement. The bow of the conductor can then be in or on a part of an interior trim be mounted on a motor vehicle. The loop can be, for example on the part of the interior lining, it can be here for Example to act around the parcel shelf, be glued on. The bow can be designed as a foil conductor or as a round conductor.
