Abstract
Description
Die Erfindung betrifft eine Dachantenne für ein Kraftfahrzeug, die auf einer metallischen Dachfläche des Kraftfahrzeugs angeordnet ist und an der zumindest ein Mobiltelefon anschließbar ist.The The invention relates to a roof antenna for a motor vehicle, the a metallic roof surface of the motor vehicle is arranged and on the at least one mobile phone connectable is.
Moderne Kraftfahrzeuge sind meist mit Dachantennen für den Betrieb mit einem Mobiltelefon ausgestattet. Häufig werden diese Dachantennen auch für andere Dienste, wie digitalen Radioempfang, satellitengestützte Navigation oder Fahrberechtigungssysteme wie Keyless-Go/Entry oder Funkzentralverriegelung benutzt.modern Motor vehicles are usually equipped with roof antennas for operation with a mobile phone. Often These roof antennas are also for other services, such as digital radio reception, satellite-based navigation or driving authorization systems such as keyless go / entry or centralized radio interlocking used.

Es ist daher eine Aufgabe der Erfindung, eine verbesserte Dachantenne für ein Kraftfahrzeug anzugeben.It is therefore an object of the invention, an improved roof antenna for a To indicate motor vehicle.
Die Aufgabe wird erfindungsgemäß gelöst durch eine Dachantenne mit den Merkmalen des Anspruchs 1.The The object is achieved by a roof antenna with the features of claim 1.
Vorteilhafte Weiterbildungen sind Gegenstand des Unteranspruchs 2.advantageous Further developments are the subject of subclaim 2.
Eine erfindungsgemäße Dachantenne für ein Kraftfahrzeug ist auf einer metallischen Dachfläche des Kraftfahrzeugs angeordnet. Über die Dachantenne sind zumindest Mobilfunk-Signale und Fahrberechtigungs-Signale sendbar und/oder empfangbar.A roof antenna according to the invention for a motor vehicle is arranged on a metallic roof surface of the motor vehicle. About the Roof antenna are at least mobile signals and driving authorization signals sendable and / or receivable.
Die Dachantenne umfasst einen nach außen wirksamen ersten Bereich und einen in einem Fahrzeuginnenraum wirksamen zweiten Bereich zum Senden und/oder Empfangen. Zu diesem Zweck ist die Dachantenne in einem Durchbruch der metallischen Dachfläche angeordnet, der erste Bereich der Antenne ragt nach außen, der zweite Bereich der Antenne hingegen in den Innenraum, so dass das Fahrberechtigungssystem, beispielsweise ein Keyless-Go-System auch während der Fahrt besser mittels der Dachantenne mit dem Fahrzeug kommunizieren kann.The Roof antenna comprises an outwardly effective first area and a second area effective for transmission in a vehicle interior and / or receiving. For this purpose, the roof antenna is in one Breakthrough of the metallic roof surface arranged, the first area the antenna sticks out, the second area of the antenna, however, in the interior, so that the driving authorization system, for example a keyless go system even while better communicate with the vehicle by means of the roof antenna can.
