In an antenna arrangement, particularly for a motor vehicle window pane antenna, a first conductor structure is provided, which is formed by the heating field of a window pane and a second conductor structure, which is configured as an antenna conductor structure and which is situated galvanically separated from the heating field. At least one conductor of the heating field runs in the form of loops between the actual heating field and an outer edge of the pane. The second conductor structure extends comb-like into the loops of this at least one conductor of the heating field.

Antenna arrangement and method

In a multiband antenna system for a vehicle windshield, an antenna conductor structure is provided in lateral recesses of the heating conductor field. The antenna conductor structure is non-electrically coupled to the heating conductor field with low resistance using high-frequency technology. This system ensures defrosting of the vehicle windshield in the entire wiped area without being affected by the antenna conductor structure.

Multiband antenna system

In a window-integrated antenna in vehicles, the heating conductor field () is used for FM reception as well as for LMS reception. At least one decoupling element () is provided for LMS reception which has a high-frequency, but non-galvanic connection to the heating conductor field (). The decoupling element () is situated in the heating conductor field, in particular between two adjacent heating conductors ().

Window-integrated antenna in vehicles

A window-integrated antenna for LMS and FM reception in mobile motor vehicles in which the window pane of the motor vehicle, in conjunction with the line structures of the antenna and the metallic frame enclosing the window pane, is used as the antenna for the reception of LMS and USW signals, the connection points of the line structures being situated in the region of one of the corners formed by the metallic frame, in proximity to which the mechanical component used as the USW/LMS antenna unit is also positioned. The first conductor section of the antenna, which is positioned perpendicularly to the upper horizontal frame part of the metallic frame, is adjoined by a second long conductor section forming an angle preferably of 90&#xb0; or forming a radius which is preferably implemented as a quarter circle having a small radius, the second conductor section running parallel to the upper horizontal frame part and extending over the largest part of the width of the window pane; and in proximity to the second lateral frame part, the second conductor section is adjoined by a third, likewise short conductor section forming an angle preferably of 90&#xb0; or forming a radius which is preferably implemented as a quarter circle having a small radius, the third conductor section extending in the direction of the upper horizontal frame part and being connected to a fourth conductor section, forming the loop; the fourth conductor section, forming with the third conductor section an angle preferably of 90&#xb0; or forming a radius which is preferably implemented as a quarter circle having a small radius, is positioned at a relatively small distance to the upper horizontal frame part and is shorter than the second conductor section of the antenna.
