- antenna couplers are known which enable capacitive and / or inductive coupling of RF signals between the antenna coupler and the antenna of the mobile radio terminal.
- DE 100 37 241 A1 describes a mobile phone holder for installation in a passenger compartment of a motor vehicle, which is attached to the windshield of the motor vehicle.
- the mobile phone holder is connected to a mounting arm with an integrated antenna and has a stabilizing device arranged at the lower end of the mobile phone holder, which stabilizes and holds the mobile radio terminal in the mobile phone holder.
- This stabilization device consists, for example, of a clamping bracket or a permanent magnet.
- the bracket arm is attached to the windshield of the motor vehicle by means of a suction device.
- the cell phone holder also has a coupling antenna arranged at the upper end of the cell phone holder, which enables a capacitive coupling of the RF signal between the antenna of the cell phone device and the cell phone holder when the mobile radio device is inserted.
- DE 297 24 042 U1 describes an antenna connector for transmitting RF signals from an external antenna to a wireless portable telephone.

- a vehicle mobile radio holder for fastening a mobile radio terminal in a vehicle, which has a housing with a first housing part shaped for receiving a mobile radio terminal, an electrical interface for connecting an external antenna to the vehicle mobile radio holder, and an electrically connected to the interface Coupling antenna for non-contact electromagnetic coupling of RF signals between the coupling antenna and the antenna of a mobile radio terminal inserted into the vehicle mobile radio holder and one or more elements for reflecting radiation from the antenna of the mobile radio terminal inserted into the vehicle mobile radio holder and not into the Coupling antenna coupled electromagnetic radiation and / or one or more elements for absorption of this electromagnetic radiation.
- the invention achieves a particularly low-loss electromagnetic coupling between typical internal antennas of mobile radio terminals, which have a pronounced directional characteristic and are usually operated in two or more different frequency bands (dual band, three band), and external antennas.
- This further reduces the proportion of the field components of the electromagnetic field emitted by the antenna of a mobile radio terminal not equipped with an antenna socket, which penetrates into the interior of the vehicle.
- the field strength caused by such a mobile radio terminal is thus reduced on the one hand by improving the electromagnetic coupling between the internal antenna of the mobile radio terminal and the antenna coupler and on the other hand by reducing the proportion of the electromagnetic field generated by the mobile radio terminal, the penetrates into the interior, is reduced.
- the improvement in the electromagnetic coupling means that the mobile radio terminal is not forced to increase the transmission power in order to ensure adequate transmission quality.
- a conductive layer arranged below the coupling antenna, viewed from the inserted mobile radio terminal is used as an element for reflecting electromagnetic radiation emitted by the antenna of the mobile radio terminal and not coupled into the coupling antenna.
- Such an arrangement increases the field strength in the direction of the front of the mobile radio terminal.
- there are larger field components in the antenna coupler coupled in as a result of which, due to the mechanisms described above, the overall field portions penetrating into the interior of the vehicle are reduced.
- a particularly advantageous arrangement of such a conductive layer consists in that the conductive layer covers at least the coverage area of the coupling antenna and / or is oriented essentially perpendicular to the main radiation direction of the antenna of the inserted mobile radio terminal. Studies have shown that particularly good results can be achieved by means of such an arrangement.
- conductive layers acting as reflection elements on the side of the antenna coupler and thus to bundle field portions radiated past the antenna coupler onto the antenna coupler.
- a particularly cost-effective and simple option from a production technology point of view consists in coating the housing parts of the vehicle cell phone holder facing away from the inserted mobile radio terminal with an electrically conductive layer or in producing these housing parts from an electrically conductive plastic.
- the housing of the vehicle mobile radio holder has a housing part which at least partially surrounds the inserted mobile radio terminal together with the housing part which is designed to accommodate the mobile radio terminal and is coated with an electrically conductive layer or consists of an electrically conductive plastic.
- This ensures that the field components emerging from the front of the mobile radio terminal are reflected on the coupling antenna and can thus be coupled in.
- a reflecting element arranged behind the coupling antenna it is also possible to generate a standing wave between two reflecting elements, which increases the efficiency of the coupling antenna and thus further reduces the coupling attenuation.
- the housing part it is expedient to produce the housing part at least in regions from an optically transparent material or composite material, so that the display of the mobile radio terminal remains legible in the inserted state.
- this housing part it is advantageous to detachably connect this housing part to the housing part designed to accommodate the mobile radio terminal.
- a locking mechanism or a locking mechanism is provided, by means of which the two housing parts can be detachably connected.
- an electromagnetic radiation-absorbing foam as the absorbing element, which, viewed from the inserted mobile radio terminal, is arranged below the coupling antenna and / or to the side of the coupling antenna.
- one or more absorber structures which absorb electromagnetic radiation and which, viewed from the inserted mobile radio terminal, are arranged below the coupling antenna and / or to the side of the coupling antenna as the absorbing element.
- Such absorbing elements on the one hand reduce the field strength of the field components penetrating into the interior of the vehicle and on the other hand improve the tunability of the coupling antenna and thus the achievable efficiency of the coupling antenna.
- the influence of changing and unforeseeable environmental conditions on the capacitive and inductive coupling between the antenna of the mobile radio terminal and the coupling antenna is reduced, so that a further optimization of this coupling can be achieved.
- the efficiency of the absorber structures can be increased by aligning them essentially perpendicular to the main radiation direction of the antenna of the inserted mobile radio terminal.
- a cost-effective and particularly effective way of arranging absorber structures from a production technology point of view is to provide housing parts of the vehicle mobile radio holder, which form the side of the housing of the vehicle mobile radio holder facing away from the inserted mobile radio terminal, at least partially with a layer composite having absorber structures.
- further housing parts of the vehicle mobile radio holder can be provided at least partially with such a layer composite. It is also possible to make this layer composite at least partially transparent by a corresponding choice of materials, so that transparent windows in a housing part acting as a cover are also possible.
- the antennas of mobile radio terminals which are not provided with a connection socket for connecting an external antenna, generally have a strong directional characteristic, so that there is a clear main radiation direction.
- coupling antennas which have three conductors which are arranged essentially parallel to one another and are coupled to one another, the outer conductors being connected to form a not entirely closed loop of conductive material which encloses the middle conductor. Furthermore, it has proven to be advantageous to use coupling antennas which are designed as a two- or multi-layer coupling structure with two or more partial coupling structures arranged one above the other. This coupling antenna also has a particularly high degree of efficiency in the special environment here.
- the higher the efficiency of the coupling antenna the better results can be achieved by using reflective and / or absorbing elements which reflect or absorb electromagnetic radiation emitted by the antenna of the mobile radio terminal and not coupled into the coupling antenna, since this also results in the influence of these elements on the tuning of the antenna coupler is reduced.

Furthermore, it is possible that resilient hook elements are connected to the housing part 791 and correspondingly arranged recesses are provided in the housing part 793, by means of which the housing part 793 can be locked with the housing part 791 after insertion of the mobile radio terminal 5.
- housing parts 791 and 793 are connected to one another by means of one or more hinges, so that the housing part 793 can be folded up or to the side.
- one or more locking or latching elements are preferably provided on the side of the housing part 793 opposite the hinges, which enable the housing part 793 to be temporarily fixed in the end position.
