Description

Appareil électronique muni d'une antenne réversiblement déconnectable Electronic device with reversibly disconnectable antenna
L'invention concerne un appareil électronique muni d'une antenne réversiblement déconnectable. L'invention a pour but de faciliter une déconnexion de l'antenne d'avec un composant électronique chargé de traiter les informations provenant de l'antenne tout en diminuant un coût de fabrication d'un tel appareil. Un appareil électronique est destiné à recevoir ou émettre des informations par radiofréquence par le biais d'une antenne. Cet appareil électronique peut être un téléphone mobile ou bien un ordinateur portable. L'invention s'applique au domaine de la connectique mais pourrait s'appliquer dans d'autres domaines. Un appareil électronique comporte un support diélectrique, au moins un composant électronique et une antenne. Le support diélectrique est revêtu d'au moins un motif de pistes conductrices d'électricité pour former un circuit imprimé. Le composant électronique est chargé de traiter un signal de radio fréquence provenant de l'antenne par l'intermédiaire du circuit imprimé. L'antenne est placée dans un boîtier délimitant l'appareil électronique.The invention relates to an electronic device provided with a reversibly disconnectable antenna. The object of the invention is to facilitate disconnection of the antenna from an electronic component responsible for processing the information coming from the antenna while reducing the manufacturing cost of such an apparatus. An electronic device is intended to receive or transmit information by radio frequency by means of an antenna. This electronic device can be a mobile phone or a laptop. The invention applies to the field of connectors but could apply in other fields. An electronic device comprises a dielectric support, at least one electronic component and an antenna. The dielectric support is coated with at least one pattern of electrically conductive tracks to form a printed circuit. The electronic component is responsible for processing a radio frequency signal coming from the antenna via the printed circuit. The antenna is placed in a box delimiting the electronic device.
Cette antenne comporte un premier plot de connexion, un deuxième plot de connexion et une masse. Cette antenne est destinée à se connecter au circuit imprimé. Plus particulièrement, l'antenne se positionne sur le support de manière à ce que les plots se connectent à une piste conductrice correspondante. L'antenne communique ainsi des informations au composant électronique et vice versa par l'intermédiaire d'une liaison s'effectuant entre chacun des plots de connexion et le composant électronique. Pour déconnecter l'antenne du composant électronique, il est connu des appareils électroniques comportant des connecteurs destinés à recevoir en correspondance des connecteurs coaxiaux complémentaires. Ces connecteurs complémentaires sont chargés de commuter l'antenne c'est à dire de la déconnecter du composant électronique. On connaît d'après l'état de la technique un connecteur monté sur un circuit imprimé prévu pour recevoir une antenne externe. Ce circuit imprimé est de préférence disposé à l'intérieur d'un boîtier d'un téléphone mobile. Le connecteur recevant l'antenne externe permet également de commuter la connexion entre le circuit imprimé et une antenne interne, ou entre le circuit imprimé et l'antenne externe. A cet effet, il comporte des lames de contact dressées de manière orthogonale au circuit imprimé. Ces lames présentent une certaine flexibilité autour d'un axe perpendiculaire à un plan du circuit imprimé. On peut également trouver des contacts disposés parallèlement au circuit imprimé. Par exemple dans le cas où les lames de contact sont dressées de manière orthogonale au circuit imprimé, le connecteur comporte deux lames de préférence disposées en vis-à-vis l'une de l'autre. Au moins l'une des lames présente une courbure de telle sorte que cette courbure vienne en contact élastiquement avec la deuxième lame. Lorsque l'antenne externe est insérée entre ces deux lames, alors la première lame courbée vient se contraindre désormais contre l'antenne. Dans cette position, la première lame élastique n'est plus au contact de la deuxième lame. Or la deuxième lame est reliée à l'antenne interne. Donc par le déplacement de cette première lame, on commute entre la première antenne et la deuxième antenne. La solution de l'état de la technique pose un problème car, il est nécessaire de positionner un connecteur susceptible de recevoir un connecteur coaxial sur le circuit imprimé et de relier ce connecteur à l'antenne. Un tel connecteur encombre le boîtier. L'appareil électronique comportant ce connecteur n'est donc pas compatible avec les exigences de miniaturisation imposées par le marché. Pour résoudre ce problème, l'invention prévoit de réaliser une antenne comportant un dispositif de déconnexion intégré. Ce dispositif de déconnexion peut former une languette élastique placée entre chaque plot de connexion de l'antenne et la piste imprimée sur le support. Cette languette est réalisée de telle manière qu'elle peut être écartée réversiblement du plot de connexion par l'intermédiaire d'une fiche qui en s'intercalant entre le plot de connexion et la languette déconnecte l'antenne de la piste. En déconnectant l'antenne de la piste cette fiche déconnecte également l'antenne du composant électronique. Cette fiche comporte une première face destinée à être au contact du plot de connexion et une deuxième face destinée à être au contact de la languette. La première face est revêtue d'un matériau diélectrique au moins sur une surface correspondant à une surface du plot de connexion contre laquelle la fiche est destinée à s'appuyer. La deuxième face est réalisée en matériau électriquement conducteur sur au moins une surface nécessaire pour qu'une liaison électrique entre la fiche et la piste s'établisse. Selon un mode préféré de l'invention, cette fiche est reliée à une antenne externe permettant de déporter l'antenne émettrice ou réceptrice de signal par rapport à l'appareil électronique. Selon une variante de l'invention, cette fiche est reliée à un appareil de mesure destiné à tester les différents composants électroniques placés dans l'appareil. L'invention a donc pour objet un appareil électronique comportant - une antenne munie d'un premier plot de connexion et d'un deuxième plot de connexion, - un support diélectrique revêtu d'une première piste conductrice d'électricité et d'une deuxième piste conductrice d'électricité, et - un composant électronique connecté aux pistes du support, caractérisé en ce que - l'antenne comporte une première languette conductrice d'électricité et une deuxième languette conductrice d'électricité, chacune reliant un plot correspondant au composant électronique en passant par une piste, et - l'antenne est réversiblement déconnectable du composant électronique par interposition d'un dispositif intermédiaire entre chacun des plots et des languettes correspondantes. L'invention sera mieux comprise à la lecture de la description qui suit et à l'examen des figures qui l'accompagnent. Celles-ci ne sont données qu'à titre indicatif et nullement limitatif de l'invention. Les figures montrent : - Figure 1 une représentation schématique d'un appareil électronique, selon l'invention, - Figure 2 : une vue agrandie de la figure 1 ; - Figure 3 : une représentation schématique en perspective de trois languettes, selon l'invention ; - Figure 4 : une représentation en perspective d'une antenne selon l'invention ; - Figure 5 : une vue agrandie représentant une disposition des languettes de l'antenne, selon l'invention ; - Figure 6 : une vue agrandie de l'antenne avant insertion d'une fiche ; - Figure 7 : une vue agrandie de l'antenne après insertion d'une fiche. La figure 1 représente un appareil électronique 1 comportant un support diélectrique 2, une antenne 3, et au moins un composant électronique 5, selon l'invention. Cet appareil 1 peut être un téléphone mobile ou bien tout autre appareil nécessitant l'utilisation d'une antenne pour recevoir des informations par radiofréquence. Le support 2 est revêtu d'une première piste conductrice d'électricité 4, d'une deuxième piste conductrice d'électricité 7 et d'une troisième piste conductrice d'électricité 6 centrale. Ces pistes peuvent être des lignes de transmissions du type ligne microbande, ou du type ligne à ruban ou bien du type ligne coplanaire. Ces pistes relient le composant 5 à l'antenne 3. Figure 2, l'antenne 3 comporte un premier plot de connexion 8, un deuxième plot de connexion 10, et un troisième plot de connexion 9, chacun de ces plots étant destiné à se lier à la première piste 4, à la deuxième piste 7 et à la troisième piste 6 respectivement. Le troisième plot de connexion 9 forme une masse et est placé entre le premier plot et le deuxième plot. Les plots de connexion précédemment cités sont formés par un produit électriquement conducteur tel que du cuivre ou de l'argent. Le composant électronique 5 est placé sur le support 2 tout en étant relié aux pistes conductrices 4, 6 et 7. Le composant électronique 5 peut ainsi traiter des informations reçues et transmises par l'antenne 3 par l'intermédiaire des pistes conductrices. Selon l'invention, l'antenne 3 comporte une première languette 12, une deuxième languette 14 et une troisième languette 13, figures 1 et 3. Chacune de ces languettes est destinée à relier le premier plot 8, le deuxième plot 10 et le troisième plot 9 à la première piste 4, à la deuxième piste 7 et à la troisième piste 6 respectivement. Chacune de ces trois languettes est formée après découpage d'une feuille de métal qui est ensuite matricée. Plus précisément, la feuille de métal est découpée de manière à obtenir une languette de forme oblongue rectangulaire, figure 3. Cette languette est ensuite pliée selon un angle d'environ 90° de manière à délimiter une première portion 18 et une deuxième portion 19 de part et d'autre d'une pliure 20. Dans un exemple, la première portion 18 est reliée directement au plot de connexion correspondant. La deuxième portion 19 est reliée directement à la piste correspondante. L'antenne 3 forme une structure porteuse en matière isolante partiellement métallisée de manière à délimiter les différents plots de connexion précédemment mentionnés, figure 4. L'antenne 3 comporte une forme en nœud papillon. Cette antenne 3 comporte une section transversale de forme globalement trapézoïdale. Cette forme trapézoïdale délimite une grande base 24 et une petite base 25, chacune de ces bases étant située dans des plans parallèles entre eux. L'antenne 3 est disposée sur le support 2 avec sa petite base 25 placée en regard du support 2. Un bloc central 26 est placé entre la grande base 24 et la petite base 25 tout en rejoignant la grande base à la petite base. De part et d'autre de ce bloc central 26 est délimité un premier espace 27 et un deuxième espace 28. La petite base 25 et la grande base 24 sont reliées par un premier côté 29 et par un deuxième côté 30 possédant chacun une longueur préférentiellement identique. Ce premier côté 29 et ce deuxième côté 30 servent plus particulièrement de support pour prolonger le premier plot 8, le deuxième plot 9 et le troisième plot 10 respectivement sous forme d'un premier bras 32, d'un deuxième bras 31 et d'un troisième bras 33. Le premier bras 32 s'étend latéralement à partir du premier plot 8 par rapport au bloc central 26. De même, le deuxième plot 10 s'étend latéralement pour former le deuxième bras 31 par rapport au bloc central 26 et selon une direction opposée à celle du premier bras 32. Le troisième bras 33 s'étend à partir du troisième plot 9 tout en rejoignant l'un des deux bras 31 ou 32 pour former une antenne de type PIFA (ou Planar Inverted F Antena). Le premier bras 32 et le deuxième bras 31 peuvent s'allonger tout en se rejoignant mais sans se toucher. Une fente 60 peut alors être délimitée, figure 1. La dimension de cette fente 60 dépend des utilisations ultérieures qui en seront faites. La fente 60 peut avoir une disposition quelconque, en fonction de l'application ou des performances de l'antenne que l'on souhaite obtenir. La fente 60 peut être formée à égale distance du premier plot et du deuxième plot comme représentée figure 1. Ou bien la fente 60 peut être plus proche du premier plot par rapport au deuxième plot. Pour augmenter les performances de l'antenne, une extrémité de chacun des bras 31 et 32 peut également être élargie. Par exemple, Figure 1 , chacun des bras recouvre toute une surface externe de l'un des côtés 29,30 et une partie d'une surface externe de la grande base 24. Mais ces bras pourraient seulement couvrir une partie centrale plus réduite de la surface externe délimitée par les côtés 29,30 et par la grande base 24 comme représenté en traits pointillés figure 1. L'antenne 3 comporte également une première glissière 34, une deuxième glissière 35 et une troisième glissière 36, figure 2. Chacune de ces glissières est formée à partir de la petite base 25 et sont creusées dans une épaisseur de l'antenne selon une direction perpendiculaire à un plan formé par le support 2. Ces glissières sont également creusées au moins partiellement sur une longueur L de l'antenne, laquelle longueur étant mesurée le long d'un axe parallèle au plan formé par le support. Ces glissières 34, 35 et 36 permettent respectivement aux languettes 12, 13 et 14 de s'y insérer. Figure 2, chacune de ces glissières délimite selon un axe perpendiculaire au plan du support une première partie 37 se prolongeant par une deuxième partie 38, la première partie 37 étant rétrécie par rapport à la deuxième partie 38 et débouchant vers l'extérieur de l'antenne 3. Chacune de ces glissières délimite alors un épaulement 39 entre la première partie 37 et la deuxième partie 38. Chacune des languettes est insérée dans une glissière correspondante par la deuxième portion 19 figure 5. Pour maintenir la languette à l'intérieur de la glissière correspondante, la languette comporte une troisième portion élargie 40 formée à un endroit situé à proximité ou correspondant à la jonction ou pliure 20 de la languette entre la première portion 18 et la deuxième portion 19, figure 3. Cette troisième portion 40 est destinée à s'insérer dans la glissière dans la deuxième partie 38 tout en venant en butée contre un obstacle (non représenté) formé par la glissière. Cette troisième portion s'encastre par complémentarité dans la glissière selon une direction parallèle au plan du support 2 de manière à empêcher la languette de sortir de la glissière. La languette est donc insérée dans la deuxième partie 38 de la glissière par coulissement longitudinal par rapport au plan du support par sa deuxième portion 19 jusqu'à ce que la première portion 18 se situe en appui contre le plot de connexion correspondant. La languette possède sur la première portion 18 une première extrémité recourbée 21 et sur la deuxième portion 19 une deuxième extrémité recourbée 22. Les extrémités 21 et 22 sont recourbées de manière à ce qu'une surface convexe recourbée formée par chacune de ces extrémités soit placée respectivement en regard du plot et de la piste correspondante. Plus précisément, la languette 3 est positionnée en appui par sa première extrémité recourbée 21 contre un plot de connexion correspondant selon une position perpendiculaire par rapport au plan formé par le support 2. La languette 3 est placée dans une glissière avec sa deuxième portion 19 placée dans la partie élargie 38 de la glissière tout en se connectant à la piste correspondante par sa deuxième extrémité recourbée 22. La deuxième portion 19 est insérée dans la glissière de telle manière que la troisième portion 40 se place en appui contre l'obstacle formé par la glissière au moment où la première extrémité recourbée 21 se situe en appuie contre le plot de connexion correspondant. La deuxième portion 19 est partiellement insérée dans la glissière de telle manière que la surface convexe formée par la deuxième extrémité 22 est placée en dehors de la glissière et est destinée à venir se contraindre contre une piste correspondante du support. L'antenne est réalisée de telle manière que la languette est contrainte élastiquement et réversiblement entre la petite base 25 de l'antenne et le support 2 lorsque l'on place l'antenne en appui contre le support par sa petite base 25. En se contraignant, la languette assure avantageusement un contact permanent de l'antenne avec le plot de connexion d'une part, et avec la piste conductrice correspondante d'autre part. L'antenne 3 est réversiblement déconnectable du composant électronique 5 de la manière suivante. La déconnexion réversible est obtenue en intercalant entre chacun des plots de connexion et la première extrémité 21 de chacune des languettes correspondantes un dispositif intermédiaire ou une fiche 43 qui déconnecte les plots des pistes correspondantes. Les languettes sont également réalisées de telle manière que lorsque l'on retire la fiche 43 d'entre les languettes et les plots de connexion, les languettes se positionnent de nouveau en appui contre les plots de connexion correspondants assurant de nouveau une connexion de l'antenne avec le composant électronique 5. La fiche 43 comporte une forme plane et est munie d'un couvercle métallique 44 et d'un isolant 45. L'isolant 45 s'encastre partiellement dans le couvercle 44 de telle manière que l'isolant délimite une protubérance 46 située en dehors du couvercle. Cette protubérance 46 comporte préférentiellement une forme parallèlipipèdique plane avec une première face 47 et une deuxième face 48. La première face 47 opposée à la deuxième face 48 est destinée à être placée au regard du plot de connexion correspondant. La deuxième face 48 est destinée à être placée au regard de la languette correspondante. La deuxième face 48 comporte un premier contact électrique 54 et un deuxième contact électrique 55 respectivement. Le premier contact 54 et le deuxième contact 55 sont placés sur la deuxième face 48 de l'isolant 45, figure 6. Un troisième contact électrique 56 est placé entre le premier et le deuxième contact tout en étant relié au couvercle 44. Ce troisième contact forme une masse. La forme recourbée de la première extrémité 21 de la première portionThis antenna comprises a first connection pad, a second connection pad and a ground. This antenna is intended to connect to the printed circuit. More particularly, the antenna is positioned on the support so that the studs connect to a corresponding conductive track. The antenna thus communicates information to the electronic component and vice versa via a link taking place between each of the connection pads and the electronic component. To disconnect the antenna from the electronic component, electronic devices are known which include connectors intended to receive corresponding coaxial connectors in correspondence. These additional connectors are responsible for switching the antenna, ie disconnecting it from the electronic component. Known from the prior art is a connector mounted on a printed circuit intended to receive an external antenna. This printed circuit is preferably placed inside a housing of a mobile phone. The connector receiving the external antenna also makes it possible to switch the connection between the printed circuit and an internal antenna, or between the printed circuit and the antenna external. To this end, it includes contact blades erected orthogonally to the printed circuit. These blades have a certain flexibility around an axis perpendicular to a plane of the printed circuit. One can also find contacts arranged parallel to the printed circuit. For example, in the case where the contact blades are erected orthogonal to the printed circuit, the connector comprises two blades preferably arranged opposite one another. At least one of the blades has a curvature so that this curvature comes into elastic contact with the second blade. When the external antenna is inserted between these two blades, then the first curved blade is now forced against the antenna. In this position, the first elastic blade is no longer in contact with the second blade. The second blade is connected to the internal antenna. So by moving this first blade, we switch between the first antenna and the second antenna. The solution of the prior art poses a problem because, it is necessary to position a connector capable of receiving a coaxial connector on the printed circuit and to connect this connector to the antenna. Such a connector clogs the housing. The electronic device comprising this connector is therefore not compatible with the miniaturization requirements imposed by the market. To solve this problem, the invention provides for making an antenna comprising an integrated disconnection device. This disconnection device can form an elastic tongue placed between each connection pad of the antenna and the track printed on the support. This tab is made in such a way that it can be removed reversibly from the connection pad by means of a plug which, being inserted between the connection pad and the tab, disconnects the antenna from the track. By disconnecting the antenna from the track, this card also disconnects the antenna from the electronic component. This plug has a first face intended to be in contact with the connection pad and a second face intended to be in contact with the tab. The first face is coated with a dielectric material at least on a surface corresponding to a surface of the connection pad against which the plug is intended to bear. The second side is made in electrically conductive material on at least one surface necessary for an electrical connection between the plug and the track to be established. According to a preferred embodiment of the invention, this plug is connected to an external antenna allowing the antenna transmitting or receiving the signal to be moved away from the electronic device. According to a variant of the invention, this plug is connected to a measuring device intended to test the various electronic components placed in the device. The invention therefore relates to an electronic device comprising - an antenna provided with a first connection pad and a second connection pad, - a dielectric support coated with a first electrically conductive track and a second electrically conductive track, and - an electronic component connected to the tracks of the support, characterized in that - the antenna comprises a first electrically conductive tab and a second electrically conductive tab, each connecting a pad corresponding to the electronic component passing through a track, and - the antenna is reversibly disconnectable from the electronic component by interposition of an intermediate device between each of the pads and corresponding tabs. The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are given for information only and in no way limit the invention. The figures show: - Figure 1 a schematic representation of an electronic device according to the invention, - Figure 2: an enlarged view of Figure 1; - Figure 3: a schematic perspective representation of three tabs, according to the invention; - Figure 4: a perspective representation of an antenna according to the invention; - Figure 5: an enlarged view showing an arrangement of the tongues of the antenna, according to the invention; - Figure 6: an enlarged view of the antenna before inserting a plug; - Figure 7: an enlarged view of the antenna after inserting a plug. FIG. 1 represents an electronic device 1 comprising a dielectric support 2, an antenna 3, and at least one electronic component 5, according to the invention. This device 1 can be a mobile phone or any other device requiring the use of an antenna to receive information by radio frequency. The support 2 is coated with a first electrically conductive track 4, a second electrically conductive track 7 and a third central electrically conductive track 6. These tracks can be transmission lines of the microstrip line type, or of the ribbon line type or of the coplanar line type. These tracks connect the component 5 to the antenna 3. Figure 2, the antenna 3 comprises a first connection pad 8, a second connection pad 10, and a third connection pad 9, each of these pads being intended to be link to first track 4, second track 7 and third track 6 respectively. The third connection pad 9 forms a mass and is placed between the first pad and the second pad. The aforementioned connection pads are formed by an electrically conductive product such as copper or silver. The electronic component 5 is placed on the support 2 while being connected to the conductive tracks 4, 6 and 7. The electronic component 5 can thus process information received and transmitted by the antenna 3 via the conductive tracks. According to the invention, the antenna 3 comprises a first tongue 12, a second tongue 14 and a third tongue 13, Figures 1 and 3. Each of these tongues is intended to connect the first pad 8, the second pad 10 and the third pad 9 at the first track 4, at the second track 7 and at the third track 6 respectively. Each of these three tabs is formed after cutting a sheet of metal which is then stamped. More specifically, the metal sheet is cut so as to obtain a rectangular oblong tongue, FIG. 3. This tongue is then folded at an angle of approximately 90 ° so as to delimit a first portion 18 and a second portion 19 of on either side of a fold 20. In one example, the first portion 18 is directly connected to the corresponding connection pad. The second portion 19 is directly connected to the corresponding track. The antenna 3 forms a carrying structure of partially metallized insulating material so as to delimit the various connection pads previously mentioned, FIG. 4. The antenna 3 comprises a shape in a bow tie. This antenna 3 has a cross section of generally trapezoidal shape. This trapezoidal shape defines a large base 24 and a small base 25, each of these bases being located in planes parallel to each other. The antenna 3 is arranged on the support 2 with its small base 25 placed opposite the support 2. A central block 26 is placed between the large base 24 and the small base 25 while joining the large base at the small base. On either side of this central block 26 is delimited a first space 27 and a second space 28. The small base 25 and the large base 24 are connected by a first side 29 and by a second side 30 each preferably having a length identical. This first side 29 and this second side 30 serve more particularly as a support for extending the first pad 8, the second pad 9 and the third pad 10 respectively in the form of a first arm 32, a second arm 31 and a third arm 33. The first arm 32 extends laterally from the first stud 8 relative to the central block 26. Similarly, the second stud 10 extends laterally to form the second arm 31 relative to the central block 26 and according to a direction opposite to that of the first arm 32. The third arm 33 extends from the third pad 9 while joining one of the two arms 31 or 32 to form a PIFA type antenna (or Planar Inverted F Antena). The first arm 32 and the second arm 31 can extend while joining but without touching. A slot 60 can then be delimited, FIG. 1. The dimension of this slot 60 depends on the subsequent uses which will be made of it. The slot 60 may have any arrangement, depending on the application or the performance of the antenna that it is desired to obtain. The slot 60 can be formed at equal distance from the first pad and the second pad as shown in Figure 1. Or the slot 60 can be closer to the first pad relative to the second pad. To increase the performance of the antenna, one end of each of the arms 31 and 32 can also be widened. For example, in Figure 1, each of the arms covers an entire external surface on one of the sides 29, 30 and part of an external surface of the large base 24. But these arms could only cover a smaller central part of the external surface delimited by the sides 29, 30 and by the large base 24 as shown in dotted lines in FIG. 1. The antenna 3 also includes a first slide 34, a second slide 35 and a third slide 36, FIG. 2. Each of these slides is formed from the small base 25 and are hollowed out in a thickness of the antenna in a direction perpendicular to a plane formed by the support 2. These slides are also hollowed out at at least partially over a length L of the antenna, which length being measured along an axis parallel to the plane formed by the support. These slides 34, 35 and 36 allow the tongues 12, 13 and 14 respectively to be inserted therein. Figure 2, each of these slides defines along an axis perpendicular to the plane of the support a first part 37 extending by a second part 38, the first part 37 being narrowed relative to the second part 38 and opening towards the outside of the antenna 3. Each of these slides then delimits a shoulder 39 between the first part 37 and the second part 38. Each of the tongues is inserted into a corresponding slide by the second portion 19 in FIG. 5. To maintain the tongue inside the corresponding slide, the tongue has a third enlarged portion 40 formed at a location near or corresponding to the junction or fold 20 of the tongue between the first portion 18 and the second portion 19, FIG. 3. This third portion 40 is intended to insert into the slide in the second part 38 while abutting against an obstacle (not shown) formed by the slide. This third portion is embedded by complementarity in the slide in a direction parallel to the plane of the support 2 so as to prevent the tongue from coming out of the slide. The tongue is therefore inserted into the second part 38 of the slide by longitudinal sliding relative to the plane of the support by its second portion 19 until the first portion 18 is located in abutment against the corresponding connection pad. The tongue has on the first portion 18 a first curved end 21 and on the second portion 19 a second curved end 22. The ends 21 and 22 are curved so that a curved convex surface formed by each of these ends is placed respectively opposite the stud and the corresponding track. More specifically, the tongue 3 is positioned in abutment by its first curved end 21 against a corresponding connection pad in a position perpendicular to the plane formed by the support 2. The tongue 3 is placed in a slide with its second portion 19 placed in the enlarged part 38 of the slide while connecting to the corresponding track by its second curved end 22. The second portion 19 is inserted in the slide so that the third portion 40 is placed in abutment against the obstacle formed by the slide when the first curved end 21 is in contact with the corresponding connection pad. The second portion 19 is partially inserted in the slide so that the convex surface formed by the second end 22 is placed outside the slide and is intended to come to constrain against a corresponding track of the support. The antenna is made in such a way that the tongue is elastically and reversibly constrained between the small base 25 of the antenna and the support 2 when the antenna is placed in abutment against the support by its small base 25. binding, the tongue advantageously ensures permanent contact of the antenna with the connection pad on the one hand, and with the corresponding conductive track on the other hand. The antenna 3 is reversibly disconnectable from the electronic component 5 in the following manner. Reversible disconnection is obtained by inserting between each of the connection pads and the first end 21 of each of the corresponding tabs an intermediate device or a plug 43 which disconnects the pads from the corresponding tracks. The tabs are also produced in such a way that when the plug 43 is removed from between the tabs and the connection pads, the tabs are again positioned in abutment against the corresponding connection pads again ensuring connection of the antenna with the electronic component 5. The card 43 has a planar shape and is provided with a cover metal 44 and an insulator 45. The insulator 45 is partially embedded in the cover 44 so that the insulator defines a protuberance 46 located outside the cover. This protuberance 46 preferably comprises a planar parallelipiped shape with a first face 47 and a second face 48. The first face 47 opposite the second face 48 is intended to be placed facing the corresponding connection pad. The second face 48 is intended to be placed facing the corresponding tab. The second face 48 has a first electrical contact 54 and a second electrical contact 55 respectively. The first contact 54 and the second contact 55 are placed on the second face 48 of the insulator 45, FIG. 6. A third electrical contact 56 is placed between the first and the second contact while being connected to the cover 44. This third contact forms a mass. The curved shape of the first end 21 of the first portion
18 de la languette permet de délimiter une ouverture 57 entre la languette et le plot de connexion correspondant, figure 7. Cette ouverture 57 permet de faciliter l'insertion de la fiche 43 entre la languette et le plot de connexion correspondant. La forme recourbée de cette extrémité 21 renforce également une élasticité de la languette et favorise un meilleur appui de la languette contre le plot de connexion correspondant et donc un meilleur contact de la languette contre le plot de connexion. Pour reconnecter le plot à la piste, il suffit de retirer la fiche 43 d'entre la languette et le plot de connexion correspondant. La première extrémité 21 se rabat alors contre le plot de connexion pour se lier physiquement au plot de connexion correspondant. Cette fiche 43 peut être reliée à une antenne externe (non représentée). Ou bien cette fiche 43 peut être reliée à un autre appareil (non représenté) chargé de tester les composants électroniques contenus dans un boîtier de l'appareil. Pour empêcher la fiche 43 de s'enfoncer plus profondément selon un axe perpendiculaire au plan du support et en direction du support lorsque l'on intercale la fiche 43 entre les languettes et les plots, la fiche 43 comporte une bordure 58, figure 7. La protubérance de la fiche 43 s'enfonce dans le bloc central 26 de l'antenne par l'intermédiaire d'une cavité 59 de forme complémentaire à cette protubérance, figure 1. La protubérance s'enfonce jusqu'à ce que la bordure vienne en appui contre un rebord délimitant la cavité 59 et contournant la cavité 59. Cette cavité 59 permet de guider le coulissement de la protubérance 46 dans le bloc central 26 de l'antenne de manière à ce que la protubérance vienne se positionner avec ses contacts en regard et au contact de la languette correspondante. Cette cavité 59 est creusée à partir de la grande base 24 de l'antenne. Selon un mode préféré de l'invention, l'antenne 3 est de type différentielle ou symétrique et le composant électronique est un émetteur- récepteur de type différentiel également. L'antenne forme ainsi un commutateur car elle permet de réaliser deux fonctions. La première fonction de l'antenne permet à l'antenne d'exercer sa fonction d'antenne émettrice ou réceptrice de signaux radio. Cette première fonction peut être exercée par l'intermédiaire de la languette qui est au contact direct par sa première portion 18 avec le plot de connexion correspondant. Une liaison du plot de connexion avec la piste correspondante alors réalisé par l'intermédiaire de la languette. La deuxième fonction de l'antenne permet à l'antenne de servir de base de relais pour une prise électrique ou fiche destinée à s'intercaler entre le plot et la languette. Cette fiche s'intercale entre la languette et le plot par écartement de la languette du plot. L'insertion de cette fiche interrompt momentanément la connexion de l'antenne avec le plot correspondant. Ainsi, l'antenne est mise en veille soit pour permettre l'insertion d'une fiche déportant une antenne à un autre endroit, soit pour permettre à une fiche de tester les différents composants électroniques présents dans l'appareil électronique. Cette antenne combine trois techniques de conception d'antenne, à savoir, le dipôle qui est dans notre cas replié, la mise à la masse telle que l'on l'utilise sur une antenne de type PIFA (Planar Inverted F Antena) et enfin la technique de la fente ou des fentes. Une autre technique utilisée pour améliorer les performances de l'antenne consiste en partant des points d'alimentation des portions à élargir progressivement la largeur des portions au fur et à mesure que l'on se rapproche de leur extrémité. Pour caler l'antenne sur le support, le support peut être creusé d'un renfoncement permettant d'accueillir la petite base 25 de l'antenne. 18 of the tongue makes it possible to delimit an opening 57 between the tongue and the corresponding connection pad, FIG. 7. This opening 57 makes it possible to facilitate the insertion of the plug 43 between the tongue and the corresponding connection pad. The curved shape of this end 21 also strengthens the elasticity of the tongue and promotes better support of the tongue against the corresponding connection pad and therefore better contact of the tongue against the connection pad. To reconnect the pad to the track, simply remove the plug 43 from between the tab and the corresponding connection pad. The first end 21 then folds against the connection pad to physically bond to the corresponding connection pad. This plug 43 can be connected to an external antenna (not shown). Or this plug 43 can be connected to another device (not shown) responsible for testing the electronic components contained in a housing of the device. To prevent the plug 43 from sinking more deeply along an axis perpendicular to the plane of the support and in the direction of the support when the plug 43 is interposed between the tongues and the studs, the plug 43 has a border 58, FIG. 7. The protrusion of the plug 43 is inserted into the central block 26 of the antenna by means of a cavity 59 of shape complementary to this protuberance, FIG. 1. The protuberance sinks until the edge comes to bear against a rim delimiting the cavity 59 and bypassing the cavity 59. This cavity 59 makes it possible to guide the sliding of the protuberance 46 in the central block 26 of the antenna so that the protuberance comes to position with its opposite contacts and in contact with the corresponding tab. This cavity 59 is hollowed out from the large base 24 of the antenna. According to a preferred embodiment of the invention, the antenna 3 is of differential or symmetrical type and the electronic component is a transceiver of differential type also. The antenna thus forms a switch because it makes it possible to perform two functions. The first function of the antenna allows the antenna to exercise its function of transmitting or receiving radio signals. This first function can be exercised by means of the tongue which is in direct contact by its first portion 18 with the corresponding connection pad. A connection of the connection pad with the corresponding track then produced by means of the tongue. The second function of the antenna allows the antenna to serve as a relay base for an electrical outlet or plug intended to be inserted between the stud and the tongue. This plug is inserted between the tongue and the stud by spacing the tongue of the stud. The insertion of this plug momentarily interrupts the connection of the antenna with the corresponding stud. Thus, the antenna is put on standby either to allow the insertion of a plug offsetting an antenna to another location, or to allow a plug to test the various electronic components present in the electronic device. This antenna combines three antenna design techniques, namely, the dipole which is folded in our case, grounding as used on a PIFA (Planar Inverted F Antena) type antenna and finally the slitting technique or slits. Another technique used to improve the performance of the antenna consists in starting from the feeding points of the portions in progressively widening the width of the portions as one approaches their end. To wedge the antenna on the support, the support can be dug a recess making it possible to accommodate the small base 25 of the antenna.
