Definitions
- the invention relates to an antenna arrangement for transmitting and receiving electromagnetic signals as well as to panes provided with such antenna arrangements.
- the reception and emission of electromagnetic waves use in particular crossed dipole antennas.
- Such an antenna is known, for example, from patent DE 699 05 436 T2.
- the disadvantage of this crossed dipole antenna lies in the fact that it has an excessive height for certain applications. If it is necessary to have a low height, the antennas used in the high frequency technique are frequently so-called patch antennas with which the antenna itself is made up of a patch. With such antennas, the patch and the incoming cable must frequently have the same layer structure, which means that the substrate material and the height of the substrate are identical for the power cable and the patch.
- an on-board DSRC unit (On-Board Unit) for motor vehicles is known from US Patent 6,421,017 Bl.
- This OBU includes an antenna and a control unit for communication with transmitter / receiver devices which are arranged along the path traveled.
- the innovation according to the mentioned US patent lies in the fact that the OBU is modified in such a way that it can be installed on the dashboard at a given distance from the windshield. This prevents the antenna characteristics from being too dispersed due to the different gaps between the antenna and the glass following imprecise mounting.
- the disadvantage with this arrangement is that the mounting location of the OBU is not variable. Another drawback appears when a window must be covered with a layer reflecting electromagnetic waves.
- the object of the invention is to provide an antenna arrangement which has small external dimensions and which can be mounted without difficulty in a given position.
- the present invention firstly provides an antenna arrangement for transmitting and receiving electromagnetic signals, the antenna arrangement comprising: a flat support substrate made of dielectric material, - a first conductive track applied to a surface of the carrier substrate, the first conductive track having at one end a contact point for collecting or injecting the signals therein and a first dipole at the opposite end, - a second conductive track applied to the other surface of the carrier substrate, - the second conductive track having at one end a contact point for collecting or injecting the signals therein and a second dipole at the opposite end, and the first and second dipoles forming a crossed dipole.
- the antenna arrangement thus consists of a flat substrate which is not electrically conductive, for example a film, on the main surfaces of which are arranged two conductive strips which act as signal lines. One end of each end is configured so that it can establish a connection to another electronic component or to another signal line. The other corresponding end of the conductive strips ends in two folded parts which form the poles of a dipole. Due to its configuration, the antenna is generally very flat.
- the dipoles which are derived from the two conductive strips are projected perpendicularly to each other so as to form a crossed dipole.
- the two poles of each dipole are preferably perpendicular to each other and the two dipoles themselves are preferably pivoted 180 ° relative to each other.
- the antenna arrangement is more flexible. This considerably simplifies mounting on, in or against a supporting structure.
- the dimensions of the conductive sections which constitute the structure of the antenna are adapted in a known manner to the operating frequency and to the bandwidth of the overall system by integrating the surrounding medium.
- the transformer ⁇ / 4 is a section of conductive strip whose impedance characteristic is adjusted so as to be able to obtain a transmission with the least possible losses of the signals received or emitted in the conductive bands which come to be connected there.
- the characteristic impedances are thus adapted to one another.
- the transformer ⁇ / 4 itself and the conductive strip which is connected thereto are produced in the form of a so-called strip line which is characterized in that the conductive strips arranged on the opposite faces of the carrier substrate coincide.
- the ribbon line is thus a bipolar line comprising conductive strips which coincide and preferably spaced apart from one another.
- the line losses in the conductive strips arranged one on the other on the two sides of the substrate can be reduced if the sections of the two conductive strips only used for signal routing have different widths, which means that the 'a so-called micro-strip line is produced.
- the longitudinal axes of the two conductive strips here extend parallel and preferably coincide.
- the electromagnetic field produced between the conductive strips is then limited in its dimensions so as to reduce radiation. It is preferable that the transition between the ribbon line and the conductive strips which come to connect to it and are used only for the transmission of the signal (microstrip line for example) does not take place suddenly with a jump in the width of the driver.
- a transition line with gradual adaptation of the width is produced in order to avoid parasitic reflections and thus extinctions and damping of the signal.
- the gradual transition is generally carried out with an adaptation element, often called ⁇ type balun ', or else it can also be for example a wide section of trapezoidal shape.
- an adaptation element often called ⁇ type balun ', or else it can also be for example a wide section of trapezoidal shape.
- This insulation can be achieved by means of an intermediate layer of the same dielectric substrate which acts as a support or by other measures, for example by providing an intermediate layer of insulating varnish.
- Shield lines can be grounded to improve shield performance. Copper has proven itself as a material for conductive tracks, firstly because it has good conductivity and secondly because it is easy to process. It is obviously possible to use other suitable conductive materials, for example metals such as tin, silver or gold.
- the electrical insulating support may consist of polyimide, for example, this material is also frequently used as a support for * flat cables. It is however also possible to use any other suitable material, as long as it has the necessary properties, in particular good dielectric properties, possibly the possibility of being implemented in the form of a film and the possibility of apply conductive structures.
- the transmission of high frequency signals can result in relatively high line and / or radiation losses, which means that the connecting lines connected to the antenna arrangement are designed for the corresponding application so that the losses are minimal. If it is necessary to have a universal or standardized interface if possible between the antenna arrangement and a processing device such as an OBU installed at a distance from this arrangement, the high-frequency signals can then, in accordance with invention, already be converted into a baseband, i.e. into lower frequency signals, using a nearby electronic circuit immediate or on the antenna arrangement itself. These can be routed to the processing device with low losses, even over long distances.
- Said electronic circuit can consist of discrete and / or integrated electronic components (CI), for example according to DE 198 56 663 C2 or DE 101 29 664 C2.
- the state of the art makes it possible to manufacture such electronic circuits in a very flat form so that they can be mounted without additional provisions on a thin and / or flexible carrier substrate (for example according to DE 100 02 777 Cl).
- the electronic circuit can also contain an amplifier, a tuner and / or other processing elements.
- the flat antenna structure according to the invention is particularly suitable for mounting on the windows of buildings or vehicles. Indeed, because of its flat shape, the antenna arrangement according to the invention can be applied discreetly on a flat object such as a window.
- the flexible antenna structure in the case of the use of a flexible film is particularly suitable for mounting on windows of buildings or vehicles. Indeed, its flexible structure also allows it to be mounted without difficulty on a curved glass. .
- the antenna arrangement according to the invention can in particular be easily glued.
- the panes used can be monolithic, that is to say composed of a single plate, or also multilayered, composed of several plates and / or films.
- the plates can be essentially transparent, made of glass or plastic, be flat or curved.
- One plate may be provided with one or more films, two or more plates may be joined together by means of an adhesive layer or an adhesive film. Thanks to the properties described above, the antenna arrangement can easily be glued to a main surface of a window.
- the whole or part of the flat antenna arrangement can also be arranged inside the sandwich structure.
- the area of the carrier substrate provided with the contact points can exit laterally from the sandwich structure and optionally be folded around the lateral edge of the glass. Connection to an additional signal line or to passive or active electrical networks is thus easy to carry out.
- the area of the antenna arrangement with the dipoles is mounted on one of the main free surfaces of the pane, the area of the arrangement d the antenna with the contact points intended to collect and / or inject the signals is mounted on the other main surface of the glass, and the carrier substrate is passed around the peripheral surface of the glass.
- the area of the antenna arrangement with the dipoles is arranged between two of the layers of the glass, the area of the antenna arrangement with the points of contact intended to collect and / or inject signals is mounted on one of the two main free surfaces of the glass, and the carrier substrate is passed around the peripheral surface of at least one of the layers of the glass.
- the carrier substrate is passed around a lateral edge of the glass, it may prove advantageous to provide the peripheral edge of the monolithic plate or, in the case of a sandwich plate structure, with one or more individual plates in this area of a recess or a recess (see for example patent EP 0 593 940 Bl). This ensures that the carrier substrate does not protrude from the initial outline of the glass.
- Such an execution with a peripheral withdrawal edge is particularly suitable when there are components on the carrier substrate whose cross section is greater than that of the conductive tracks and the dipoles, for example an electronic circuit for adaptation for the frequency or. to a connection connector. These components can then be arranged while being particularly protected in the hollow formed on the peripheral edge where they are less exposed than in the case of an assembly on the surface of the plate. After the mounting of the carrier substrate has been completed, these components can be molded with an appropriate sealing mass with the aid of which said recess can then be surface-leveled.
- a window is provided with a layer or coating which reflects electromagnetic waves but which is optically transparent, it must however be ensured that the antenna arrangement is not shielded by this layer or coating.
- the layer or coating should therefore not be disposed between the antenna arrangement and the transmitter or receiver of the antenna signals. Otherwise, the layer or coating must include an area allowing the waves to pass (communication window). Obviously, it is also not necessary to provide a layer or coating reflecting the electromagnetic waves between the two dipoles.
- the area of the antenna arrangement containing the dipoles is arranged to correctly transmit or receive the electromagnetic signals, the latter being disposed more towards the outside that said reflective layer after mounting the window for example on a car.
- Said layers or coatings reflecting electromagnetic waves are used, for example, for thermal insulation or can act as surface heating.
- a particular advantage of the invention lies in the fact that if the antenna arrangement is fixed on or against a window pane or at least the zone containing the dipoles, it is not necessary to adapt or treat a coating which reflects electromagnetic waves possibly present and oriented more inward after mounting the window for example on a car.
- the pane is a multilayer plate, the area of the antenna arrangement containing the dipoles can be arranged between the coating or the reflective layer and the inner face of the outer layer of the pane, that is to say the layer intended to be the most outside.
- the area of the antenna arrangement containing the dipoles can be arranged between the coating or the reflective layer and the internal face of the plate.
- the antenna arrangement according to the invention When the antenna arrangement according to the invention is mounted in or against a window pane, it can be protected by a layer of opaque or translucent paint on one of the plates or one of the films so that it cannot not be seen from the outside. This protection can be applied for aesthetic reasons, but also to protect certain materials against ultraviolet rays.

- the shielding strips 8 and 9 are earthed or connected to the ground terminal and contribute to improved shielding of the conductive strips 320 and 420 which transmit the signals. Interference signals acting from the outside can thus effectively be stopped.
