Embodiment Construction

[0053] figure 1 A schematic diagram of a vehicle 1 with an antenna arrangement 2 according to the invention is shown. An antenna arrangement 2 is provided for receiving radio signals 3 from satellites 4 , in particular GNSS signals. The antenna arrangement comprises a first antenna 2.1 and a second antenna 2.2. The first antenna 2.1 has a fin-shaped housing. The printed circuit board with the GNSS patch antenna elements is in a fin-shaped housing. The first antenna 2 . 1 is attached to the vehicle body frame, in particular to the roof, in the rear region of the vehicle 1 . The GNSS patch antenna element has a patch antenna which is provided for connection to the first receiving unit. A first antenna 2.1 is provided for receiving a first radio signal 3.1. The second antenna 2 . 2 is integrated in the windshield substrate 5 of the vehicle 1 . A second antenna 2.2 is provided for receiving a second radio signal 3.2.

Abstract

The present invention relates to an antenna arrangement for a vehicle. The antenna arrangement comprises at least a first antenna for receiving a first wireless signal transmitted by satellites of a navigation system and having a first receiving unit for generating first position data, a second antenna for receiving a second wireless signal transmitted by satellites of the navigation system and having a second receiving unit for generating second position data, a position module connected to the first receiving unit and to the second receiving unit for receiving the first position data from the first receiving unit and the second position data from the second receiving unit, the position module being provided for combining the first position data and the second position data and for determining a geographical position of a vehicle, and the first antenna and the second antenna having a distance from one another of at least half a wavelength of the first wireless signal.

Description

technical field [0001] The invention relates to an antenna arrangement for a vehicle, a vehicle having an antenna arrangement and a method for determining the position of a vehicle. Background technique [0002] Vehicles are equipped with a large number of antennas for different services. Such vehicles often have systems for navigation. The navigation system here utilizes the Global Navigation Satellite System (GNSS). Known systems are, for example, the Global Positioning System (GPS, Global Positioning System) or the Global Navigation Satellite System (GLONASS, GLObal Navigation Satellite System). Navigation systems are used in vehicles for route guidance and for supplying other control devices with route and position data. Corresponding antennas are usually fastened outside the vehicle interior, such as for example on the body frame. [0003] A so-called shark-fin antenna is known from US 20140176374 A1, the outer housing of which is configured in the shape of a fin an...
