This unit is arranged in a particular area of ​​the body or a part thereof in the vehicle. From being are contacting available to antenna conductor structures which are applied to a slice of the vehicle to contact. This contacting means, such as spring elements, the antenna conductor patterns are connected to the disk via electrical leads with the signal-processing unit. To this end between the housing of the signal processing unit and the contacting means present a cantilever arm, wherein the cantilever arm is fixedly connected to the housing of the signal-processing unit and spaced carries at its end the contacting device. The electrical lead or the corresponding required number of leads between the contacting means and the signal processing unit are arranged on or in the cantilever arm and are so assembled that the housing of the signal processing unit with its cantilever arm (or several cantilever arms) with arranged at the end contacting devices form a unit. Since such a unit must be installed in the production of the vehicle in this, it is necessary to have a fixed electrical connection between the contacting means and the signal processing unit perform. This requires a complex construction of this entire preassembled unit which brings the one hand, problems with the storage and transport with it and, secondly, having tolerance problems because the contact means have come on this preassembled unit always at predetermined points (contact points) of the antenna conductor structure to plant what due to tolerances in the manufacture of both the preassembled unit and the contact points on the vehicle window is not the case. Moreover, during transport, the problem that the extension arms can be damaged in any other way, so that the entire unit is unusable bend or break with the contacting devices arranged thereon or. The same applies to the case that the entire unit is damaged in an accident, so they must be replaced in their entirety.

p0003From the <patcit id="pcit0002" dnum="DE20210286U"><text>DE 202 10 286 U</text></patcit> is known an adapter for connecting flat connection contacts of conductor tracks arranged on a dielectric material, to a plug connection of further networks. In this prior art, the signal processing unit is an amplifier circuit to which a plug can be connected. Thus, the connection between the signal processing unit and the electrical lead is detachable In contrast, the connection of the electrical supply line to contact surfaces on a vehicle window can not be solved, because in the area of ​​the contact area on the vehicle window, a contact adapter is adhered, after the gluing operation is no longer can be removed from the disc. This will repair the defect case more difficult since also the contact adapter must be completely replaced with the lead and the connector thereon with removal of the windshield. The same applies in the event that the unit is composed of defective plug, electric cable and contact adapter and it must be replaced. In this case, the replacement of the complete vehicle window is required, which is labor intensive and costly.

This has the advantage that the signal processing unit can be handled separately from the contacting means via which the contact to the antenna conductor structure. Thus, the signal processing unit forms with its contacting means no complex unit more, but it can in the production of the vehicle, the signal-processing unit (or more where appropriate) can be mounted in the provided space, as well as the contacting means, so that both the signal processing unit as can also be the contact means arranged and fixed in position at the exact spot that are provided for them. Subsequently affixing the electrical lead to the signal processing unit, whereby it is firstly possible that these electrical lead is arranged already firmly to the contacting means or the electric lead there is detachably connectable to the contacting devices. There is thus the possibility of the electrical lead between the signal-processing unit and the associated contact means removably attached to the signal-processing unit and / or to be arranged detachably on the contacting means. Moreover, there is the possibility of providing in the way between the contacting means and the signal processing unit further releasable connections.

p0007The manner of construction and the contacting of the contacting means is arbitrary and may be the respective application, in particular the available space adapted. Similarly, various species come from electrical supply lines into consideration, in particular round cables, flat cables or dergleiche. It is important that in each case a contact point, which is connected to a part of the antenna conductor structure, can be connected to the contact means and the electric supply lead to the signal processing unit.
