The present invention is characterized in that it enables almost all mobile phones available on the market, in particular GSM phones, to connect with a single holder. Most mobile phones have their antennas in a defined area on the back of the device arranged. Preferably, this antenna is in the upper region of the arranged mobile phone. This antenna is mostly either horizontally or vertically to the housing of the mobile phone arranged.

Of the Inventive holder for a mobile phone is characterized by the fact that in the holder a variety of antennas, which are preferably receiving antennas, at least but two antennas are arranged, which at least over a portion of the holder are arranged. By this arrangement In most cases an antenna is optimally positioned in relation to the antenna arranged by mobile phone. In this way it is now possible for each mobile phone on the market, the antenna coupling unit in the holder adapt by the antenna coupling unit for coupling with the antenna in the mobile phone uses the holder and the optimal antenna of existing in the holder antennas directly is used for coupling.

The manufacturer of the holder has knowledge of types and types of mobile phones and the arrangement of the antennas in selbigen. About arranged on the holder retaining cheeks, the holder for Adoption of almost any shape and any model of a mobile phone can be customized.

For this the cheeks are movable on the holder can be arranged, while on the Size of the mobile phone can be adjusted can be fixed and on the base plate of the holder. Then the mobile phone is inserted into the cheeks. As a result, now the position of the antenna of the mobile phone relatively known to the holder. Through the cheek can thus a Position of the mobile antenna of the mobile phone chosen which is almost optimally located to one of the antennas in the holder is.

To achieve a good coupling between the antenna in the holder and the antenna in the mobile phone, the following is provided:
The holder already contains the antennas already described. These couple the arranged in the mobile phone antenna. This coupling is passive and without direct electrical / mechanical contact between the antenna in the mobile phone and the antennas in the holder. Signals which are emitted by the mobile telephone via this antenna are received by the antennas in the holder and coupled there. This is also done in the opposite direction, so that signals from one of the antennas in the holder to the antenna of the mobile phone are transferable. Furthermore, on one of the retaining cheeks, which fix the mobile phone on the holder, electrical and mechanical interfaces are present, which couple existing on the mobile phone and externally accessible electrical and mechanical interfaces. In addition, an external mobile radio antenna is connected to the holder, which is preferably arranged outside of the motor vehicle. Signals which are now received by this external mobile radio antenna, to the antennas, which are arranged in / on the holder, passed and coupled by at least one of these antennas in the antenna of the mobile phone and received there and evaluated. The mobile telephone processes these signals and transmits the voice or data signals, which are obtained from this received signal, via the mechanical and / or electrical interfaces, which are arranged in the holder, to corresponding points in the motor vehicle, for example to the hands-free device. There, these signals are then processed and played back. In the opposite direction, speech signals which a user inputs into the mobile telephone located in the holder in a device provided for this purpose are transmitted to the corresponding elements in the holder. These signals are routed to the mobile phone, which converts the signals into antenna signals and emits them via the antenna arranged in the mobile telephone. These antenna signals are received by the antennas in the holder and routed to and radiated from the external mobile antenna.

It is now recognizable due to the described mode of operation, that for optimal operation a good coupling between the antennas in the holder and the antenna of the mobile phone are necessary is. Here it has been proven that already at a deviation from the optimal position by just a few millimeters, a damping of about 10%. Therefore, it is essential to an optimal location of the antennas, or at least one of the antennas in the holder, to the antenna to reach in the mobile phone.

To ensure this, two different approaches are possible:
One approach is that templates are provided for the holder and its base plate, by means of which a user can set the optimum position of the antenna coupling unit. For each mobile telephone, or its series, a template is provided which defines the optimum position of the antenna coupling unit and the retaining cheeks. Thus, a user can adapt the holder to the respective mobile telephone.

In A further embodiment of the invention provides that already on the base plate for frequent on the Market mobile phones corresponding positions on the holder are pre-marked. A user can then use the antenna coupling unit and possibly the retaining cheeks on the base plate of the holder to the Move marked positions and thus the holder to the respective customize mobile phone.

In a further advantageous embodiment of the invention is provided that in or on the holder, a corresponding electrical unit is present. This electrical unit is connected via an external connection energized, preferably via a connection to the electrical system of a motor vehicle. The electrical unit measures the degree of coupling between the antenna in the mobile phone and everyone the individual arranged in the holder antennas and assigns the mobile phone then automatically the antenna with the highest degree of coupling.

In a further advantageous embodiment of the invention is in Holder one or at least one antenna arranged, that is in the holder integrated. Preferably, at least two antennas are integrated. The Antennas are arranged parallel or perpendicular to each other. In parallel position these are in one plane, in a vertical position arranged in two levels with each other. The antennas are each arranged so that the antennas do not touch each other.

In a further advantageous embodiment of the invention several antennas each parallel and each perpendicular to each other in the holder, preferably in that area in which normally the antenna integrated in the mobile telephone is arranged.

is now a mobile phone inserted in the holder, so recognizes this is the electrical unit of the holder based on the contact the existing on the mobile phone mechanical / electrical contact points. The electrical unit then instructs the mobile phone to transmit signals to radiate the integrated antenna. These signals then become received from the antenna integrated in the holder. The electric Unit then measures the degree of coupling of each individual antenna with the antenna integrated in the mobile phone. These values will be stored in a cache. Subsequently, the determined electrical unit the best degree of coupling and only activates the antenna in the holder, which has the best degree of coupling reaches the existing antenna in the mobile phone.

In A further advantageous embodiment provides that the individual antennas of the electrical unit in the form of a Antenna array are interconnected. this makes possible it then, the radiated from the antenna electrical / magnetic Waves over the antenna array to receive and thus one to achieve a much better degree of coupling. This interconnection will made in a known manner by the electrical unit. This takes place for a further configuration optimization.

Should now from the antennas in the holder signals to the antenna in the mobile phone are directed, this is done in the reverse direction. The electric Unit routes the signals received from the external antenna be directly to the selected antenna in the holder the best coupling factor for the antenna integrated in the mobile phone further. In the further embodiment, the signal is over the antenna array formed by the antennas in the holder is radiated.

On this way is an optimal coupling between the antenna (s) guaranteed in the holder and the antenna in the mobile phone.
