La présente invention concerne les appareils électroniques à antenne du type en plaque comme celle qui est décrite dans le EP-A 0 938 157.The present invention relates to electronic devices with a plate type antenna such as that described in EP-A 0 938 157.
Il est déjà connu, notamment de ce document, une antenne en plaque qui comporte une feuille en un matériau électriquement isolant, un élément rayonnant en un matériau électriquement conducteur disposé sur une première face de cette feuille, l'élément rayonnant étant conformé en boucle ouverte comme celui qui est décrit dans le EP-A 0 938 157 ou mêmeen boucles multiples comme l'élément rayonnant qui est décrit et illustré dans le US-A-4 443 805. Cette boucle est sensiblement symétrique par rapport à un plan perpendiculaire à la feuille, les deux brins d'extrémités de la boucle ouverte étant situés en regard l'un de l'autre et de part et d'autre du plan de symétrie. L'antenne comporte aussi une ligne d'alimentation située sur la seconde face de la feuille opposée à la première, la ligne d'alimentation ayant une forme sensiblement similaire à celle de la boucle ouverte, une première extrémité de la ligne d'alimentation étant située dans le plan de symétrie au niveau du point de la boucle ouverte situé dans le plan de symétrie, et des moyens de connexion à un circuit de traitement et une source d'énergie.It is already known, in particular from this document, a plate antenna which comprises a sheet made of an electrically insulating material, a radiating element made of an electrically conductive material placed on a first face of this sheet, the radiating element being shaped in open loop like the one described in EP-A 0 938 157 or even in multiple loops like the radiating element which is described and illustrated in US-A-4 443 805. This loop is substantially symmetrical with respect to a plane perpendicular to the sheet, the two ends of the ends of the open loop being located opposite one another and on either side of the plane of symmetry. The antenna also includes a feed line located on the second face of the sheet opposite to the first, the feed line having a shape substantially similar to that of the open loop, a first end of the feed line being located in the plane of symmetry at the point of the open loop located in the plane of symmetry, and means for connection to a processing circuit and an energy source.
Cette antenne peut aussi avantageusement comporter d'autres composants comme ceux qui sont mentionnés et décrits dans les documents référencés ci- dessus.This antenna can also advantageously include other components such as those mentioned and described in the documents referenced above.
Cette antenne est très intéressante, car elle présente l'avantage de pouvoir être miniaturisée et donc, si elle est intégrée dans un appareil électronique, de contribuer à la miniaturisation de l'appareil électronique lui-même, comme un récepteur du type GPS, c'est-à-dire un appareil récepteur de signaux émis par un satellite ou analogue, par exemple des signaux vidéo ou des signaux de fréquences pouvant aller jusqu'à douze GHz. La présente invention a donc pour but de réaliser un appareil électronique comportant une antenne en plaque du type de celle décrite dans l'un ou l'autre des deux documents référencés auparavant.This antenna is very interesting, because it has the advantage of being able to be miniaturized and therefore, if it is integrated into an electronic device, to contribute to the miniaturization of the electronic device itself, like a GPS type receiver, c that is to say a device for receiving signals transmitted by a satellite or the like, for example video signals or signals of frequencies up to twelve GHz. The present invention therefore aims to produce an electronic device comprising a plate antenna of the type described in one or the other of the two documents referenced before.

According to another characteristic of the invention, the electronic circuit consists of at least one of the following circuits: amplifier, electronic GPS receiver, video signal receiver, video signal transmitter, video signal transmitter-receiver. Other characteristics and advantages of the present invention will appear during the following description given with reference to the drawings annexed by way of illustration but in no way limitative, in which:
Les figures 1 à 3 représentent trois vues d'un mode de réalisation d'un appareil électronique selon l'invention, la figure 1 en représentant une vue de dessous, la figure 2 en représentant une vue de face partiellement en écorché et la figure 3 en représentant une vue de dessus.Figures 1 to 3 show three views of an embodiment of an electronic device according to the invention, Figure 1 showing a bottom view, Figure 2 showing a partially cutaway front view and Figure 3 representing a top view.
Par référence aux trois figures, l'appareil électronique selon l'invention comporte une feuille 1 en un matériau électriquement isolant, un élément rayonnant 2 en un matériau électriquement conducteur disposé sur une première face 3 de la feuille, cet élément rayonnant 2 étant conformé en au moins une boucle ouverte sensiblement symétrique par rapport à un plan 6 perpendiculaire à la feuille, les deux brins d'extrémités 4, 5 de la boucle ouverte étant situés en regard l'un de l'autre et de part et d'autre du plan de symétrie 6.With reference to the three figures, the electronic device according to the invention comprises a sheet 1 of an electrically insulating material, a radiating element 2 of an electrically conductive material disposed on a first face 3 of the sheet, this radiating element 2 being shaped as at least one open loop substantially symmetrical with respect to a plane 6 perpendicular to the sheet, the two end strands 4, 5 of the open loop being located opposite one another and on either side of the plane of symmetry 6.
L'appareil comporte en outre une ligne d'alimentation 7 située sur la seconde face 8 de la feuille opposée à la première 3, la ligne d'alimentation ayant une forme sensiblement similaire à celle de la boucle ouverte, une première extrémité 9 de la ligne d'alimentation étant située dans le plan de symétrie 6 au niveau du point 10 de la boucle ouverte situé dans ce plan.The apparatus further comprises a supply line 7 located on the second face 8 of the sheet opposite to the first 3, the supply line having a shape substantially similar to that of the open loop, a first end 9 of the supply line being located in the plane of symmetry 6 at the point 10 of the open loop located in this plane.
La boucle ouverte peut avoir différentes formes, mais présentera avantageusement l'une des formes suivantes : circulaire, rectangulaire. Cependant, il est précisé que la boucle formée par la ligne d'alimentation 7 peut avoir une longueur comme représenté sur les figures, à savoir plus courte que celle qui est formée l'élément rayonnant 2. La longueur de la ligne d'alimentation sera adaptée au type de longueurs d'ondes que l'antenne sera destinée à recevoir. L'homme du métier saura sans difficulté l'adapter à la réception optimale, par exemple au moyen d'un analyseur de réseau ou analogue.The open loop can have different shapes, but will advantageously have one of the following shapes: circular, rectangular. However, it is specified that the loop formed by the supply line 7 can have a length as shown in the figures, namely shorter than that which is formed the radiating element 2. The length of the supply line will be adapted to the type of wavelengths that the antenna will be intended to receive. Those skilled in the art will easily know how to adapt it to optimal reception, for example by means of a network analyzer or the like.
L'appareil comporte en outre un circuit électronique 11 implanté sur la feuille 1, ce circuit à au moins une borne d'entrée 12, une borne de sortie 13 et une borne de masse 14 étant monté en série, entre ses deux bornes d'entrée et de sortie, dans la ligne d'alimentation 7 définie ci-dessus.The apparatus further comprises an electronic circuit 11 located on the sheet 1, this circuit having at least one input terminal 12, an output terminal 13 and a terminal earth 14 being mounted in series, between its two input and output terminals, in the supply line 7 defined above.
Il comporte aussi un connecteur de type coaxial 15 comportant donc une électrode centrale 16 et une gaine périphérique 17, toutes deux électriquement conductrices et électriquement isolées l'une de l'autre, des premiers moyens de liaison électrique 18 pour relier électriquement l'électrode centrale 16 à la première extrémité 9 de la ligne d'alimentation 7, et des seconds moyens de liaison électriqueIt also includes a coaxial type connector 15 therefore comprising a central electrode 16 and a peripheral sheath 17, both electrically conductive and electrically isolated from each other, first electrical connection means 18 for electrically connecting the central electrode 16 at the first end 9 of the supply line 7, and second electrical connection means
19 pour relier électriquement la gaine périphérique 17 à la borne de masse 14 du circuit électronique 11 et à l'élément rayonnant 2. Selon une réalisation préférentielle de l'appareil selon l'invention, le connecteur coaxial 15 est monté en coopération sur l'élément rayonnant 2, sensiblement au point 10 de la boucle ouverte situé dans le plan de symétrie 6, qui est le point neutre de la partie antenne de l'appareil.19 for electrically connecting the peripheral sheath 17 to the earth terminal 14 of the electronic circuit 11 and to the radiating element 2. According to a preferred embodiment of the device according to the invention, the coaxial connector 15 is mounted in cooperation on the radiating element 2, substantially at point 10 of the open loop located in the plane of symmetry 6, which is the neutral point of the antenna part of the device.
Dans ce cas, les premiers moyens 18 de liaison électrique définis ci-dessus sont avantageusement constitués par le fait que l'électrode centrale 16 traverse la feuille 1 sensiblement perpendiculairement à cette feuille, l'une 20 des extrémités de l'électrode étant montée au contact conducteur de la première extrémité 9 de la ligne d'alimentation 7. Quant aux seconds moyens de liaison électrique 19, ils sont constitués par le fait que la gaine périphérique 17 est montée au contact conducteur et l'élément rayonnant 2 et par un conducteur électrique 21 reliant la borne de masseIn this case, the first electrical connection means 18 defined above advantageously consist of the fact that the central electrode 16 passes through the sheet 1 substantially perpendicular to this sheet, one of the ends of the electrode being mounted at the conductive contact of the first end 9 of the supply line 7. As for the second electrical connection means 19, they consist of the fact that the peripheral sheath 17 is mounted on the conductive contact and the radiating element 2 and by a conductor electric 21 connecting the ground terminal
14 du circuit électronique 11 à l'élément rayonnant 2.14 from the electronic circuit 11 to the radiating element 2.
Dans une réalisation préférentielle, ce conducteur électrique 21 traverse la feuille 1 en passant dans un orifice 22 dont l'axe est sensiblement perpendiculaire à cette feuille. II est apparent que l'appareil électronique tel que décrit ci-dessus peut être plus facilement miniaturisé par le fait que le circuit électronique est intégré sur la même feuille que celle qui sert de support à l'antenne.In a preferred embodiment, this electrical conductor 21 passes through the sheet 1 by passing through an orifice 22 whose axis is substantially perpendicular to this sheet. It is apparent that the electronic device as described above can be more easily miniaturized by the fact that the electronic circuit is integrated on the same sheet as that which serves as a support for the antenna.
C'est ainsi un tel appareil électronique à antenne miniaturisée en plaque trouve des applications particulièrement avantageuses, notamment dans le cas où le circuit électronique 11 est constitué par l'un des circuits suivants : amplificateur du type préamplificateur, amplificateur différentiel, etc., récepteur électronique du typeThis is how such an electronic device with a miniature plate antenna finds particularly advantageous applications, in particular in the case where the electronic circuit 11 consists of one of the following circuits: amplifier of the preamplifier type, differential amplifier, etc., receiver type electronics
GPS, un récepteur de signaux vidéo, émetteur de signaux vidéo, émetteur-récepteur de signaux vidéo, etc. Dans une réalisation possible et avantageuse, le matériau électriquement isolant dans lequel est réalisée la feuille 1 est un substrat, par exemple du type verre époxy ou analogue.GPS, video signal receiver, video signal transmitter, video signal transmitter and receiver, etc. In a possible and advantageous embodiment, the electrically insulating material in which the sheet 1 is made is a substrate, for example of the epoxy glass type or the like.
Dans ce cas, l'élément rayonnant 2 et la ligne d'alimentation 7 peuvent être facilement obtenus à partir du substrat initialement métallisé, dont une partie de la couche métallique à été enlevée par tout moyen tel que de l'acide, etc., pour ne laisser que les zones métalliques formant l'élément rayonnant et la ligne d'alimentation. In this case, the radiating element 2 and the supply line 7 can be easily obtained from the initially metallized substrate, from which a part of the metallic layer has been removed by any means such as acid, etc. to leave only the metal areas forming the radiating element and the supply line.
