Abstract
Description
Die Erfindung betrifft eine Antennenvorrichtung und ein Fahrzeug mit der Antennenvorrichtung.The invention relates to an antenna device and a vehicle with the antenna device.
Die meisten Kraftfahrzeuge weisen heute eine Elektronikausrüstung auf, die zumindest eine Antenne erfordert. Beispielsweise weisen die Kraftfahrzeuge eine Antenne für einen Radioempfang, für einen Mobilfunkempfang und/oder für einen GPS-Empfang auf. Häufig werden Antenneneinrichtungen außen auf einem Karosserieteil, insbesondere auf einem Kraftfahrzeugdach, angeordnet.Most motor vehicles today have an electronic equipment that requires at least one antenna. For example, the motor vehicles have an antenna for radio reception, for mobile radio reception and / or for GPS reception. Frequently, antenna devices are arranged on the outside of a body part, in particular on a motor vehicle roof.
Die Aufgabe, die der Erfindung zugrunde liegt, ist, eine Antennenvorrichtung sowie ein Fahrzeug mit der Antennenvorrichtung zu schaffen, die beziehungsweise das einen Beitrag leistet, einen zuverlässigen Betrieb einer Kommunikationsverbindung mit hoher Datenrate zu ermöglichen.The object underlying the invention is to provide an antenna device as well as a vehicle with the antenna device, which contributes to enabling a reliable operation of a communication link with a high data rate.
Die Aufgabe wird gelöst durch die Merkmale der unabhängigen Patentansprüche. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.The object is solved by the features of the independent claims. Advantageous developments of the invention are characterized in the subclaims.
Gemäß einem ersten Aspekt zeichnet sich die Erfindung aus durch eine Antennenvorrichtung für ein Fahrzeug mit einem Fahrzeugdach, das ein Karosserieblech aufweist. Die Antennenvorrichtung umfasst eine erste Teilvorrichtung, die an einer nach außen, aus dem Fahrzeug heraus, gerichteten Seite des Fahrzeugdachs angeordnet ist und ein Antennengehäuse und eine in dem Antennengehäuse angeordnete erste Antenne aufweist. Des Weiteren umfasst die Antennenvorrichtung eine zweite Teilvorrichtung, die an einer nach innen, in das Fahrzeug hinein, gerichteten Seite des Fahrzeugdachs angeordnet ist, und die eine zweite Antenne aufweist.According to a first aspect, the invention is characterized by an antenna device for a vehicle having a vehicle roof, which has a body panel. The antenna device comprises a first sub-device, which is arranged on a side of the vehicle roof directed outwards, out of the vehicle, and has an antenna housing and a first antenna arranged in the antenna housing. Furthermore, the antenna device comprises a second sub-device which is arranged on a side of the vehicle roof directed inwards into the vehicle and which has a second antenna.
Vorteilhafterweise ermöglicht dies mit geringem Herstellungs- und/oder Montageaufwand eine Mehrantennenanordnung zu realisieren. Die erste und zweite Antenne können vorteilhafterweise sehr gut elektromagnetisch entkoppelt sein und nur eine sehr geringe Signalkorrelation aufweisen, da das Karosserieblech als Schirmblech genutzt werden kann. Dies kann ermöglichen, dass die erste und zweite Antenne für ein Mehrfach-Eingabe-Mehrfach-Ausgabe-Antennensystem (MIMO, Multiple-Input-Multiple-Output) genutzt werden können. Die erste und zweite Antenne derart auszubilden und anzuordnen, dass sie eine zueinander orthogonale Antennenpolarisation aufweisen, ist hierfür nicht notwendig aufgrund der guten elektromagnetischen Schirmung durch das Karosserieblech. Mobilfunkübertragungssysteme zumindest ab der vierten Generation (4G), beispielsweise Long Term Evolution (LTE), bedingen eine Übertragung mit hoher spektraler Effizienz. Um dies zu ermöglichen, können solche Übertragungssysteme mehrere Sendeantennen und mehrere Empfangsantennen zur Datenübertragung für eine Kommunikationsverbindung aufweisen. Die Anzahl der Sendeantennen kann unterschiedlich sein von der Anzahl der Empfangsantennen. Ein MIMO-Kanal, der durch die Sendeantennen und die Empfangsantennen ausgebildet wird, kann in mehrere räumliche Kanäle zerlegt werden. Ein Nutzen mehrerer räumlicher Kanäle zur Übertragung von Daten kann einen höheren Gesamtdurchsatz und/oder eine höhere Zuverlässigkeit der Datenübertragung ermöglichen.Advantageously, this makes it possible to realize a multi-antenna arrangement with little manufacturing and / or assembly effort. The first and second antenna can advantageously be very well decoupled electromagnetically and have only a very low signal correlation, since the body panel can be used as a shroud. This may allow the first and second antennas to be used for a multiple input multiple output (MIMO) antenna system. The first and second antennas are designed and arranged such that they have mutually orthogonal antenna polarization, this is not necessary because of the good electromagnetic shielding by the body panel. Mobile transmission systems at least from the fourth generation (4G), for example, Long Term Evolution (LTE), require a transmission with high spectral efficiency. In order to make this possible, such transmission systems may comprise a plurality of transmission antennas and a plurality of reception antennas for data transmission for a communication connection. The number of transmit antennas may be different than the number of receive antennas. A MIMO channel formed by the transmit antennas and the receive antennas can be split into multiple spatial channels. Using multiple spatial channels to transmit data may allow for higher overall throughput and / or higher reliability of data transmission.
Beispielsweise sind die erste und zweite Teilvorrichtung in einem vorgegebenen Dachbereich, beispielsweise im Heckbereich, des Fahrzeugs in räumlicher Nähe, insbesondere gegenüberliegend, angeordnet.For example, the first and second sub-device in a predetermined roof area, for example in the rear area, the vehicle in spatial proximity, in particular opposite, arranged.
In einer vorteilhaften Ausgestaltung sind die erste Antenne und die zweite Antenne ausgebildet, Signalwellen eines gleichen vorgegebenen Frequenzbandes zu empfangen und/oder zu senden. Das Frequenzband kann beispielsweise zumindest einen Teil eines Frequenzbereichs von näherungsweise 700 MHz bis 900 MHz umfassen. Die erste und/oder die zweite Teilvorrichtung kann jeweils weitere Antennen umfassen, die jeweils ausgebildet sind, Signalwellen unterschiedlicher Frequenzbänder zu empfangen und/oder zu senden.In an advantageous embodiment, the first antenna and the second antenna are configured to receive and / or transmit signal waves of the same predetermined frequency band. For example, the frequency band may comprise at least a portion of a frequency range of approximately 700 MHz to 900 MHz. The first and / or the second sub-device may each comprise further antennas, which are each designed to receive and / or transmit signal waves of different frequency bands.
In einer weiteren vorteilhaften Ausgestaltung weist die erste Antenne eine invertierte F-Antenne auf. Die invertierte F-Antenne kann vorteilhafterweise einen geringen Bauraum aufweisen.In a further advantageous embodiment, the first antenna has an inverted F antenna. The inverted F antenna can advantageously have a small space.
In einer weiteren vorteilhaften Ausgestaltung weist die zweite Antennen eine invertiere L-Antenne auf.In a further advantageous embodiment, the second antenna has an inverted L antenna.
Gemäß einem zweiten Aspekt zeichnet sich die Erfindung aus durch ein Fahrzeug, das ein Fahrzeugdach und eine Antennenvorrichtung gemäß dem ersten Aspekt aufweist. Das Fahrzeugdach weist ein Karosserieblech auf. Die Antennenvorrichtung ist an dem Fahrzeugdach angeordnet. Hierbei beziehen sich vorteilhafte Ausgestaltungen des ersten Aspekts auch auf den zweiten Aspekt.According to a second aspect, the invention is characterized by a vehicle having a vehicle roof and an antenna device according to the first aspect. The vehicle roof has a body panel. The antenna device is arranged on the vehicle roof. In this case, advantageous embodiments of the first aspect also relate to the second aspect.
