Description

ANTENNE DE VITRE AVEC UN COMPOSANT A HAUTE FREQUENCE GLASS ANTENNA WITH HIGH FREQUENCY COMPONENT
L'invention se rapporte à une vitre d'antenne avec un composant électrique à haute fréquence disposé fixement sur une de ses surfaces et une structure de conducteur qui est électriquement raccordée au composant.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.
La DE-A1-198 23 202 décrit un dispositif d'antenne pour véhicule, dans lequel les raccordements de pied de toutes les antennes disposées sur une vitre (de verre) transparente rassemblés en des points de contact d'un champ de contact sont entourés d'un socle de plastique disposé sur la surface de la vitre, dans lequel un composant à haute fréquence, par exemple un amplificateur, est fixé de façon détachable. Pour les raccordements électriques entre le composant à haute fréquence et les points de contact, on utilise ici des contacts à ressort. Ceux-ci sont certes simples à monter et à démonter, mais ils sont en même temps relativement sensibles à la corrosion et aux vibrations mécaniques qui se produisent.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. For the electrical connections between the high frequency component and the contact points, 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.
La DE-A1-198 56 663 divulgue un dispositif pour la mise en contact d'une antenne disposée sur une vitre de fenêtre avec un boîtier d'amplificateur fixé sur la vitre de fenêtre. La zone de raccordement est entourée d'une couche de colle, tandis que les contacts électriques sont réalisés de préférence par brasage. Le US-A-6.087.996 montre une disposition analogue avec des contacts à ressort, dans laquelle le boîtier d'amplificateur est fixé de façon détachable à la surface de la vitre à l'aide d'un assemblage velcro.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.
Par la DE-A1-197 35 395, il est connu de coupler une couche plate conductrice servant d'antenne sur une vitre (de verre) transparente de façon capacitive à un conducteur de raccordement, avec lequel le signal d'antenne est acheminé jusqu'au récepteur radio. En l'occurrence, le couplage capacitif est effectué d'une façon telle qu'une électrode en forme de bande soit imprimée sur la face d'une vitre feuilletée tournée vers l'habitacle, tandis que la couche conductrice est disposée sur une surface située intérieurement dans le composite. La longueur de l'électrode en forme de bande doit être de plus de 5 cm, et sa largeur de 5 à 10 mm.By DE-A1-197 35 395, it is known to couple a flat conductive layer serving as an antenna on a transparent (glass) window in a capacitive manner to a connecting conductor, with which the signal antenna is routed to the radio receiver. In this case, the capacitive coupling is performed in such a way that a strip-shaped electrode is printed on the face of a laminated window facing the passenger compartment, while the conductive layer is arranged on a surface located internally in the composite. The length of the strip-shaped electrode should be more than 5 cm, and its width from 5 to 10 mm.
Le document DE-A1-198 58 299 montre un système d'antenne pour un dispositif de communication de données dans un véhicule: des deux côtés d'une surface de montage diélectrique telle qu'un vitrage, peuvent être reliés ensemble par couplage capacitif des composants du système d'antenne disposés sur des électrodes de couplage plates.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.
Les documents US-4, 931,805 et US-4,931,806 décrivent une antenne de téléphone placée sur la vitre d'un véhicule: un module extérieur porte l'antenne tandis qu'un module intérieur est relié à cette antenne par transmission de signal capacitif. Le vitrage est utilisé comme diélectrique. Les deux modules sont fixés aux surfaces du vitrage par des bandes adhesives double-face .Documents US-4, 931,805 and US-4,931,806 describe a telephone antenna placed on the glass of a vehicle: an outdoor module carries the antenna while an indoor module is connected to this antenna by capacitive signal transmission. Glazing is used as a dielectric. The two modules are fixed to the glazing surfaces by double-sided adhesive strips.
L'invention a pour objet, à partir d'une vitre connue avec un composant à haute fréquence, de proposer une autre variante de liaison pour la mise en contact du composant à haute fréquence disposé sur la surface de la vitre.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.
Conformément à l'invention, cet objectif est atteint en ce que le composant à haute fréquence et la structure de conducteur sont prévus sur la même surface de la vitre, et que le composant à haute fréquence présente au moins une électrode de couplage plate, qui est maintenue à une distance définie de la structure de conducteur plate conduisant des signaux d'antenne à haute fréquence, au moyen d'une couche intermédiaire diélectrique, pour former ledit raccordement électrique Les caractéristiques des revendications secondaires indiquent des variantes avantageuses de cet objet.According to the invention, 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. The features of the secondary claims indicate advantageous variants of this object.
Une multitude de signaux d'antenne peuvent aussi être transmis par voie capacitive dans un composant à haute fréquence, avec des pertes par amortissement négligeables, même sans points de contact propres, au moyen d'une électrode plate. A cet effet, il faut d'abord prévoir sur la vitre une structure de conducteur plate conduisant les signaux d'antenne. Il peut s'agir en l'occurrence de signaux d'antennes diversité pour la réception radio et TV. Ce peut être aussi des signaux plus combinés de radio/TV et radiotéléphonie, GPS et analogues. Ces signaux peuvent être filtrés et exploités séparément dans le composant à haute fréquence au moyen de composants adéquats, en particulier amplifiés et restitués ultérieurement.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. For this purpose, it is first necessary to provide on the glass 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.
Naturellement, les deux électrodes de couplage doivent se recouvrir entièrement, parce que la capacité est proportionnelle à la surface des électrodes. Un recouvrement incomplet conduit à une réduction de la capacité de couplage et ainsi à un accroissement de l'amortissement aux basses fréquences. On pourra assurer ledit recouvrement en règle générale par le fait que la structure de conducteur utilisée comme point de couplage est réalisée de façon étendue sur la surface de la vitre sous la forme d'une électrode de couplage, respectivement de surface, associée, de telle manière que de faibles écarts de position restent inoffensifs.Naturally, 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.
Un grand avantage de cette disposition est que le composant à haute fréquence peut être réalisé sous la forme d'une platine simple sans contact galvanique vers la vitre.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.
La couche intermédiaire diélectrique peut être une couche d'air d'épaisseur définie, s'il est possible de garder celle-ci durablement constante après la fixation du composant à haute fréquence sur la vitre d'antenne. Cela peut être réalisé par exemple au moyen de dispositifs de montage appropriés avec des pièces d ' écartement . En règle générale, on collera le composant à haute fréquence sur la surface de la vitre. Lorsqu'il comprend son propre boîtier, seuls les raccordements électriques extérieurs doivent encore être réalisés après le collage. Lorsque le composant à haute fréquence ne comporte pas son propre boîtier, il peut - naturellement après un contrôle de fonctionnement approfondi - être surmoulé durablement avec une masse appropriée. On écarte ainsi de manière pratiquement hermétique les influences ambiantes, bien que le composant à haute fréquence ne doive pas avoir lui-même de gaine propre. Ceci contribue aussi à la diminution de sa saillie au-dessus de la surface de la vitre. Précisément dans le cas d'application de la vitre d'antenne dans un véhicule, une protection fiable contre l'humidité et la vapeur d'eau est indispensable.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. As a general rule, 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.
La largeur de la zone de transmission capacitive peut, dans une variante préférée, être réalisée au moyen d'une bande adhésive (double face) d'épaisseur définie, qui forme d'une part directement une couche intermédiaire diélectrique entre la structure de conducteur du côté de la vitre et l'électrode de couplage du composant à haute fréquence. D'autre part, la fixation du composant à haute fréquence est de cette façon très fortement simplifiée. La matière de la bande adhésive assure durablement le respect de la largeur désirée, respectivement de la distance des électrodes de la zone de transmission capacitive. Un autre avantage de cette disposition est le court chemin du signal depuis l'antenne jusqu'au composant à haute fréquence, surtout lorsque celui-ci comporte un amplificateur. Car aussi bien des pertes que des influences perturbatrices restent de cette manière très faibles. Le composant à haute fréquence peut aussi comprendre par exemple un ou plusieurs tuners et analogues en plus d'un ou de plusieurs amplificateurs.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. On the other hand, the fixing of the high frequency component is in this way very greatly simplified. 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.
De même, le remplacement d'un composant éventuellement défectueux n'est pas particulièrement compliqué. On peut enlever la masse de surmoulage, éventuellement en même temps que le composant devenu inutilisable, et enlever l'assemblage collé, aucune opération particulière n'étant nécessaire pour détacher les contacts, tout comme avec des contacts à ressort.Likewise, 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.
Il va de soi que la disposition, décrite ici, d'un composant à haute fréquence sur une vitre d'antenne peut être utilisée aussi bien sur des vitres en verre que sur des vitres en plastique, naturellement aussi tant sur des vitres monolithiques que sur des vitres feuilletées .It goes without saying that the arrangement, described here, of a high-frequency component on an antenna window can be used both on glass windows and on plastic windows, naturally both on monolithic windows and on laminated windows.
La liaison entre la structure de conducteur et les éléments d'antenne ainsi que la fabrication et la nature de ces derniers ne seront pas discutés davantage ici, parce que de nombreuses réalisations et combinaisons ont été décrites antérieurement dans l'état de la technique.The connection between the conductor structure and the antenna elements as well as the manufacture and the nature of the latter will not be discussed further here, because many embodiments and combinations have been described previously in the state of the art.
Il faut cependant constater que la transmission des signaux de la structure de conducteur à l'électrode de couplage sous le composant à haute fréquence n'est pas limitée à une unique zone ou capacité de transmission. Il est au contraire également possible de diviser la structure de conducteur (imprimée ou collée) en plusieurs parties électriquement séparées, dont chacune est reliée à un champ d'antenne ou analogue. Autrement dit, plusieurs points de couplage peuvent ainsi être localement proches sur une surface de vitre. Les signaux conduits par ceux-ci sont couplés parallèlement dans le composant à haute fréquence recouvrant cette pluralité de capacités de transmission à l'aide d'un nombre correspondant d'électrodes de couplage associées individuellement de manière spatiale et fonctionnelle.However, it should be noted that 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. On the contrary, it is also possible to divide the conductor structure (printed or glued) into several electrically separated parts, each of which is connected to an antenna field or the like. In other words, 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.
On peut ainsi rassembler localement, par exemple en un point sur une surface de la vitre, des signaux de structures d'antennes, qui sont distribuées sur plusieurs vitres (par exemple vitres latérales et arrière d'autos), comme cela peut être prévu surtout dans les systèmes d'antenne diversité. Il faut toutefois être attentif au fait que, dans de telles solutions multiples, des distances de contacts trop petites (des parties de structure de conducteur les unes par rapport aux autres) peuvent conduire à une diaphonie des signaux. Pour réduire ou éviter cet effet, la distance entre deux faces de contact devrait être plus grande que les longueurs des arêtes de contacts éloignées l'une de l'autre de cette distance.It is thus possible to collect locally, for example at a point on a surface of the window, signals from antenna structures, which are distributed over several windows (for example side and rear windows of cars), as can be expected above all. in diversity antenna systems. However, it should be borne in mind that, in such multiple solutions, too small contact distances (parts of the conductor structure relative to each other) can lead to crosstalk of the signals. To reduce or avoid this effect, the distance between two contact faces should be greater than the lengths of the contact edges distant from each other by this distance.
D'autres détails et avantages de l'objet de l'invention apparaîtront par le dessin d'un exemple de réalisation et par sa description détaillée qui suit.Other details and advantages of the subject of the invention will appear from the drawing of an exemplary embodiment and from its detailed description which follows.
La figure unique montre, dans une représentation simplifiée (sans échelle particulière), une coupe à travers la région de bord d'une vitre d'antenne, sur laquelle un composant à haute fréquence est durablement fixé à l'aide d'une bande adhésive double face.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.
Une vitre de verre monolithique transparente 1 porte, près du bord d'une de ses surfaces, aussi bien un revêtement opaque 2 qu'une structure de conducteur électriquement conductrice 3 disposée sur cette dernière. Le revêtement opaque et la structure de conducteur sont de préférence réalisés de façon connue par sérigraphie à l'aide de pâtes correspondantes, qui peuvent être ensuite cuites (sur une vitre de verre) . Le revêtement opaque 2 ne doit pas être électriquement conducteur. En revanche, la structure de conducteur 3 est de préférence réalisée de façon connue avec une pâte de sérigraphie à haute teneur en argent, comme cela est connu par des barrettes collectrices de courant pour des conducteurs de chauffage imprimés et cuits ou aussi pour des couches chauffantes sur des vitres d'automobiles. De manière idéale, la structure de conducteur 3 peut aussi, dans le présent cas d'application, avoir comme autre fonction d'être une barrette collectrice de ce type. De façon connue, des structures d'antennes peuvent aussi être utilisées comme éléments chauffants, lorsqu'on leur fournit une tension d'alimentation à partir du réseau de bord.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. On the other hand, 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. Ideally, the conductor structure 3 can also, in the present application, have the other function of being a busbar of this type. In known manner, antenna structures can also be used as heating elements, when supplied with a supply voltage from the on-board network.
Sur la structure de conducteur 3 est à nouveau fixé, au moyen d'une mince bande adhésive double face 4, un composant à haute fréquence HF, sur lequel on reviendra encore plus loin.On the conductor structure 3 is again fixed, by means of a thin double-sided adhesive strip 4, a high-frequency HF component, to which we will return even further.
Entre la structure de conducteur 3 et la bande adhésive pourrait se trouver, selon la demande du client final, une autre couche visuellement opaque de masquage, qui n'est pas électriquement conductrice.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.
A l'état monté de la vitre d'antenne 1 dans une carrosserie de véhicule (non représentée) , ce dispositif est généralement situé sur une surface tournée vers l'espace intérieur du véhicule, et il est masqué vers l'intérieur par un revêtement intérieur. Le revêtement opaque 2 masque la structure de conducteur 3 et le composant à haute fréquence HF visuellement vers l'extérieur. Une mince électrode plate 5 en un métal bon conducteur, par exemple en cuivre, est assemblée directement avec la bande adhésive 4.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. A thin flat electrode 5 made of a good conductive metal, for example copper, is assembled directly with the adhesive strip 4.
La bande adhésive 4 forme une couche de séparation diélectrique d'épaisseur définie entre la structure de conducteur 3 et l'électrode plate 5. Son épaisseur détermine la distance des deux électrodes, qui ne devrait pas dépasser environ 0,5 mm, et prend ainsi une part déterminante dans le comportement de transmission capacitive du dispositif.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.
Il ne faut pas de contact galvanique entre la structure de conducteur 3 et le composant à haute fréquence HF. Au contraire, la structure de conducteur 3 sert de première électrode d'un couplage capacitif de signaux dans le composant à haute fréquence HF par 1 ' électrode plate 5. L'épaisseur de l'électrode peut aller de 10 à lOOμm et la superficie est d'environ 900 mm2. Dans le cas de l'exemple, cette dernière a une longueur d'environ 100 mm, une largeur de 10 mm et une épaisseur de 35 μm. La structure de conducteur présente à cet endroit une largeur de plus de 10 mm et une épaisseur de 4 - 15 μm avec une teneur en argent de > 70 % et une résistance spécifique de 2,85 - 5,45 * 10"6 [Ω*cm] . On a ainsi atteint un comportement de transmission satisfaisant dans le domaine de fréquences supérieur à 40 MHz, donc des signaux pour VHF, FM, UHF, etc., sont transmis de manière sûre et avec une bonne qualité. L'affaiblissement reste faible, on a ainsi mesuré un affaiblissement de 0,69 dB seulement entre 76MHz et 860 MHz (respectivement des fréquences pour les signaux FM et UHF) .There must be no galvanic contact between the conductor structure 3 and the high frequency HF component. On the contrary, 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 μm 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 μm. The conductor structure here has a width of more than 10 mm and a thickness of 4 - 15 μm with a silver content of> 70% and a specific resistance of 2.85 - 5.45 * 10 "6 [Ω * 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).
Les dimensions géométriques des composants du matériel peuvent être maintenues constantes dans des domaines de tolérance étroits. Il est important que la couche adhésive ne permette pas la pénétration d'humidité. On emploie de préférence une colle acrylate sous forme de film ou de mousse, dont la permittivité est comprise entre 2 et .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.
On forme ainsi au total une capacité convenant pour la transmission de signaux à haute fréquence depuis la structure de conducteur 3 à l'électrode plate 5 respectivement dans des composants ultérieurs du composant à haute fréquence HF.In total, a capacity is thus formed which is suitable for the transmission of high frequency signals from the conductor structure 3 to the flat electrode 5 respectively in subsequent components of the high frequency HF component.
L'électrode plate 5 est de l'autre côté reliée à une couche élastique relativement épaisse 6, de préférence à nouveau collée, qui peut et doit compenser de légères courbures de la surface de la vitre 1. L'électrode plate 5 elle-même est suffisamment mince pour pouvoir suivre toute courbure de la surface importante dans la pratique. Ces courbures n'ont dès lors qu'une influence négligeable sur la largeur de la fente respectivement sur l'épaisseur de la bande adhésive 4. Vient ensuite une plaque porteuse 7, qui forme 1 ' armature arrière mécanique du composant à haute fréquence HF. Selon l'environnement de montage, cette plaque porteuse peut être rigide ou flexible. Sur celle-ci est fixée une platine porteuse 8 avec un équipement électronique qu'il n'y a pas lieu d'expliciter davantage. Celle-ci peut également, comme la plaque porteuse, être rigide ou flexible selon les exigences imposées, si l'environnement de montage l'exige (par exemple très petits rayons de courbure de la surface de la vitre à l'endroit de montage) ou si le composant à haute fréquence présente des dimensions superficielles relativement grandes.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. Next comes a carrier plate 7, which forms the mechanical rear reinforcement of the HF high frequency component. Depending on the mounting environment, this carrier plate can be rigid or flexible. On this is fixed a carrier plate 8 with electronic equipment that there is no need to explain further. This can also, like the carrier plate, be rigid or flexible depending on the requirements imposed, if the mounting environment requires it (for example very small radii of curvature from the surface of the glass at the mounting location) or if the high frequency component has relatively large surface dimensions.
Enfin, un câble de signalisation 9 est relié électriquement à la platine porteuse, respectivement à des pistes conductrices formées sur celle-ci. Des signaux sont transmis par ce câble de signalisation 9 (blindé) de plus de 5μm d'épaisseur vers des appareils disposés en aval, non représentés ici (récepteurs de radio ou de TV, postes téléphoniques, etc.); en outre, il sert pour alimenter le composant à haute fréquence HF en courant électrique et éventuellement pour le relier à la terre.Finally, 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 5μm 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.
Tout ce dispositif est enrobé d'une masse de surmoulage 10, qui adhère fermement à la surface de la vitre d'antenne 1, respectivement au revêtement opaque 2 et protège hermétiquement le composant à haute fréquence HF contre l'humidité et l'encrassement.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.
La liaison entre le composant à haute fréquence et la structure de conducteur a été décrite ci-dessus comme capacitive. En variante, elle peut être du type inductive en comprenant deux bobines. The connection between the high frequency component and the conductor structure has been described above as capacitive. As a variant, it can be of the inductive type by comprising two coils.
