Embodiment Construction

[0025] The examples described below are preferred embodiments of the present invention. In this exemplary embodiment, the described components of the embodiment are each individual features of the invention that can be considered independently of one another and which accordingly also develop the invention independently of one another. The disclosure content therefore also includes other combinations of features than those of the illustrated embodiments. Furthermore, the described embodiments can also be supplemented by other described features of the invention.

[0026] The single figure shows a schematic perspective view of an antenna holding device 10 according to an embodiment. The monopole antenna 12 held by the antenna support plate 14 may be provided on the antenna holding device 10 . The antenna support plate 14 can have one or more stiffening ribs 16 in order to increase the stiffness of the antenna support plate 14 and thereby reduce vibrations of the antenna suppo...

Abstract

The invention relates to an antenna-retaining device (10) for a motor vehicle. The antenna-retaining device (10) comprises: an antenna carrier plate (14) for retaining a monopole antenna (12) in an emitting position; and a motor-vehicle coupling means (18) for fastening the antenna carrier plate (14) to a vehicle body (20). In the emitting position, a distance exists between the retained monopole antenna (12) and the vehicle body (20). The antenna carrier plate (14) is electrically conductive and thus forms an electrical counterpoise to the monopole antenna (12). The antenna-retaining device (10) also comprises an electrically conductive tab element as a counterpoise extension (24). The antenna carrier plate (14) and the counterpoise extension (24) are interconnected. When the monopole antenna (12) is retained in the emitting position, the monopole antenna and the counterpoise extension (24) are arranged on opposite sides of the antenna carrier plate (14), and a surface of the counterpoise extension and a planar emitting region or a longitudinal axis of the monopole antenna include an angle in the range of 90 degrees to 180degrees.

Description

technical field [0001] The invention relates to an antenna holding device for a motor vehicle and a motor vehicle with the antenna holding device. Background technique [0002] Antennas, in particular monopole antennas, also known as quarter-wave transmitters, can be installed in the bumper area of ​​a motor vehicle. For this purpose, the monopole antenna is usually positioned on a support of the antenna holding device and mounted on the frame of the motor vehicle. The antenna holding device can be used as an electrical ground grid for the monopole antenna and at the same time place the monopole antenna in a suitable space. Antenna holding devices should be kept at a distance from other components for electromagnetic compatibility. [0003] An antenna for a vehicle is known from DE 10 2015 225 756 A1, which has a carrier, wherein an antenna structure for transmitting and / or receiving high-frequency signals is arranged on the carrier. [0004] A bumper is known from DE 196...
