Definitions
- the invention relates to an antenna window with a high frequency electrical component fixedly arranged on one of its surfaces and a conductor structure which is electrically connected to the component.
- DE-A1-198 23 202 describes an antenna device for a vehicle, in which the foot connections of all the antennas arranged on a transparent (glass) pane gathered at contact points of a contact field are surrounded a plastic base disposed on the surface of the glass, in which a high frequency component, for example an amplifier, is detachably fixed.
- a high frequency component for example an amplifier
- spring contacts are used here. These are easy to assemble and disassemble, but at the same time they are relatively sensitive to corrosion and the mechanical vibrations that occur.
- DE-A1-198 56 663 discloses a device for bringing an antenna placed on a window pane into contact with an amplifier box fixed to the window pane.
- the connection area is surrounded by a layer of adhesive, while the electrical contacts are preferably made by soldering.
- US-A-6.087.996 shows a similar arrangement with spring contacts, in which the amplifier housing is detachably attached to the surface of the glass by means of a velcro assembly.
- Document DE-A1-198 58 299 shows an antenna system for a data communication device in a vehicle: on both sides of a dielectric mounting surface such as glazing, can be connected together by capacitive coupling of the components of the antenna system arranged on flat coupling electrodes.
- the object of the invention is, from a known pane with a high-frequency component, to propose another variant of connection for bringing the high-frequency component placed on the surface of the pane into contact.
- this objective is achieved in that the high frequency component and the conductor structure are provided on the same surface of the glass, and that the high frequency component has at least one flat coupling electrode, which East maintained at a defined distance from the flat conductor structure conducting high frequency antenna signals, by means of a dielectric intermediate layer, to form said electrical connection.
- a multitude of antenna signals can also be transmitted capacitively in a high frequency component, with negligible damping losses, even without own contact points, by means of a flat electrode.
- a flat conductor structure conducting the antenna signals.
- These may be diversity antenna signals for radio and TV reception. It can also be more combined signals of radio / TV and radiotelephony, GPS and the like. These signals can be filtered and exploited separately in the high-frequency component by means of suitable components, in particular amplified and restored later.
- the two coupling electrodes must overlap completely, because the capacity is proportional to the surface of the electrodes. Incomplete overlap leads to a reduction in coupling capacity and thus to an increase in damping at low frequencies.
- This overlap can generally be ensured by the fact that the conductor structure used as a coupling point is produced in an extended manner on the surface of the glass in the form of a coupling electrode, respectively of surface, associated, such so that small differences in position remain harmless.
- a great advantage of this arrangement is that the high frequency component can be produced under the form of a simple plate without galvanic contact towards the glass.
- the intermediate dielectric layer may be an air layer of defined thickness, if it is possible to keep it durably constant after fixing the high-frequency component on the antenna glass. This can be achieved, for example, by means of suitable mounting devices with spacers.
- the high frequency component will be bonded to the surface of the glass. When it includes its own housing, only the external electrical connections must still be made after bonding. When the high-frequency component does not have its own housing, it can - naturally after a thorough functional check - be permanently molded with an appropriate mass. Ambient influences are thus practically sealed off, although the high-frequency component itself must not have its own sheath. This also contributes to the reduction of its projection above the surface of the glass. Precisely in the case of application of the antenna glass in a vehicle, reliable protection against humidity and water vapor is essential.
- the width of the capacitive transmission zone may, in a preferred variant, be produced by means of an adhesive strip (double-sided) of defined thickness, which on the one hand directly forms a dielectric intermediate layer between the conductor structure of the side of the glass and the high frequency component coupling electrode.
- an adhesive strip double-sided
- the material of the adhesive strip ensures lasting compliance with the desired width, respectively the distance of the electrodes from the capacitive transmission zone. Another advantage of this arrangement is the short signal path from the antenna to the high frequency component, especially when the latter includes an amplifier. Because both losses and disruptive influences remain very small in this way.
- the high frequency component may also include, for example, one or more tuners and the like in addition to one or more amplifiers.
- replacing a possibly defective component is not particularly complicated.
- the over-molding mass can be removed, possibly at the same time as the component which has become unusable, and the bonded assembly can be removed, no particular operation being necessary to detach the contacts, just as with spring contacts.
- the transmission of signals from the conductor structure to the coupling electrode under the high-frequency component is not limited to a single zone or transmission capacity.
- several coupling points can thus be locally close on a glass surface.
- the signals conducted by them are coupled in parallel in the high frequency component covering this plurality of transmission capacities using a corresponding number of coupling electrodes associated individually in a spatial and functional manner.
- the single figure shows, in a simplified representation (without particular scale), a section through the edge region of an antenna window, on which a high-frequency component is permanently fixed using an adhesive strip double sided.
- a transparent monolithic glass pane 1 carries, near the edge of one of its surfaces, both an opaque coating 2 and a conductor structure electrically conductive 3 disposed thereon.
- the opaque coating and the conductor structure are preferably produced in a known manner by screen printing using corresponding pastes, which can then be baked (on a glass pane).
- the opaque coating 2 must not be electrically conductive.
- the conductor structure 3 is preferably produced in a known manner with a screen printing paste with a high silver content, as is known by current collector bars for printed and baked heating conductors or also for heating layers. on automobile windows.
- the conductor structure 3 can also, in the present application, have the other function of being a busbar of this type.
- antenna structures can also be used as heating elements, when supplied with a supply voltage from the on-board network.
- Between the conductive structure 3 and the adhesive strip could be, according to the request of the end customer, another visually opaque masking layer, which is not electrically conductive.
- this device In the mounted state of the antenna window 1 in a vehicle body (not shown), this device is generally located on a surface facing the interior space of the vehicle, and it is masked inward by a coating inside.
- the opaque coating 2 masks the conductor structure 3 and the high frequency HF component visually outward.
- the adhesive strip 4 forms a dielectric separation layer of thickness defined between the conductor structure 3 and the flat electrode 5. Its thickness determines the distance of the two electrodes, which should not exceed approximately 0.5 mm, and thus takes a decisive part in the capacitive transmission behavior of the device.
- the conductor structure 3 serves as the first electrode for a capacitive coupling of signals in the high-frequency HF component by the flat electrode 5.
- the thickness of the electrode can range from 10 to 100 ⁇ m and the area is about 900 mm 2 . In the case of the example, the latter has a length of approximately 100 mm, a width of 10 mm and a thickness of 35 ⁇ m.
- the conductor structure here has a width of more than 10 mm and a thickness of 4 - 15 ⁇ m with a silver content of> 70% and a specific resistance of 2.85 - 5.45 * 10 "6 [ ⁇ * cm] This has achieved satisfactory transmission behavior in the frequency range above 40 MHz, therefore signals for VHF, FM, UHF, etc. are transmitted securely and with good quality. remains weak, we thus measured an attenuation of 0.69 dB only between 76MHz and 860 MHz (frequencies for FM and UHF signals respectively).
- the geometrical dimensions of the components of the material can be kept constant within narrow tolerance ranges. It is important that the layer adhesive does not allow penetration of moisture.
- An acrylate adhesive is preferably used in the form of a film or foam, the permittivity of which is between 2 and.
- the flat electrode 5 is on the other side connected to a relatively thick elastic layer 6, preferably again bonded, which can and must compensate for slight curvatures of the surface of the window 1.
- the flat electrode 5 itself is thin enough to be able to follow any curvature of the surface that is important in practice. These curvatures therefore have only a negligible influence on the width of the slot respectively on the thickness of the adhesive strip 4.
- a carrier plate 7 which forms the mechanical rear reinforcement of the HF high frequency component.
- this carrier plate can be rigid or flexible.
- a signal cable 9 is electrically connected to the carrier plate, respectively to conductive tracks formed thereon. Signals are transmitted by this signal cable 9 (shielded) of more than 5 ⁇ m thickness towards downstream devices, not shown here (radio or TV receivers, telephone sets, etc.); in addition, it is used to supply the high frequency HF component with electric current and possibly to connect it to earth.
- This entire device is coated with an overmolding mass 10, which adheres firmly to the surface of the antenna glass 1, respectively to the opaque coating 2 and hermetically protects the high-frequency component HF against humidity and fouling.
- connection between the high frequency component and the conductor structure has been described above as capacitive.
- it can be of the inductive type by comprising two coils.
