Description

La présente invention concerne le domaine des antennes de télécommunications transmettant des ondes radioélectriques dans le domaine des hyperfréquences au moyen d'éléments rayonnants. La présente invention se rapporte plus particulièrement à un dispositif permettant le couplage et la fixation de manière rapide, fiable et bon marché d'un élément rayonnant sur un support métallique plan au cours de l'assemblage d'une antenne.The present invention relates to the field of telecommunications antennas transmitting radio waves in the microwave domain by means of radiating elements. The present invention relates more particularly to a device for coupling and fixing quickly, reliably and inexpensively a radiating element on a flat metal support during the assembly of an antenna.

Elle s'étend en outre à une antenne comportant un tel dispositif et au procédé d'assemblage d'une telle antenne.It also extends to an antenna comprising such a device and to the assembly method of such an antenna.

La réalisation d'une antenne comporte des étapes de fixation mécanique de ses composants les uns aux autres. Aujourd'hui, la plupart des fabricants d'antennes utilisent un assemblage mécanique comportant un châssis constituant un axe mécanique central sur lequel sont fixés tous les autres composants, tels que des éléments rayonnants, des diviseurs de puissance, des déphaseurs, des parois réfléchissantes, des éléments parasites, etc... Une fois tous les éléments assemblés autour du châssis, l'ensemble est entouré d'un radome.The realization of an antenna comprises steps of mechanical fastening of its components to each other. Today, most antenna manufacturers use a mechanical assembly comprising a chassis constituting a central mechanical axis on which are fixed all the other components, such as radiating elements, power dividers, phase shifters, reflective walls, parasitic elements, etc. Once all the elements assembled around the frame, the whole is surrounded by a radome.

Afin de supporter les efforts mécaniques dus au poids des composants et à l'environnement, ce châssis est fabriqué à partir d'un matériau métallique ayant une dureté et une épaisseur suffisantes. Cette contrainte initiale limite les choix mécaniques ultérieurs. Elle impose que les compromis dans la conception, notamment entre les facteurs de nature électrique et mécanique et le coût de fabrication, soient principalement guidés par les exigences mécaniques en vue d'assurer la stabilité des performances. Par exemple, une antenne d'environ 2 m de long travaillant dans une bande de fréquences autour de 2 GHz comporte un châssis d'aluminium ayant une épaisseur comprise entre 1,5 mm et 2,5 mm. Alors que si l'on ne tient compte strictement que de la profondeur liée à l'effet de peau dans le domaine de fréquence, l'épaisseur requise ne serait que de moins de 0,1 mm. La présence de connexions métalliques et leur positionnement entre les composants obliger à choisir des solutions mécaniques comme le vissage ou la soudure. Ces techniques d'assemblage induisent des coûts supplémentaires, en particulier à cause du temps requis pour effectuer l'opération et par la nécessité d'un contrôle poussé de la qualité de la liaison réalisée, et elles rendent le désassemblage périlleux voire impossible. Autrement, à cause de la dégradation inévitable des contacts électriques, l'antenne pourrait être confrontée à des problèmes de produits d'intermodulation (PIM) qui traduisent une distorsion des signaux transitant par l'antenne, tel que la perte de performances si ces dégradations surviennent aux endroits où les champs électromagnétiques sont intenses.In order to withstand mechanical stresses due to the weight of the components and the environment, this frame is made from a metallic material having sufficient hardness and thickness. This initial constraint limits the subsequent mechanical choices. It requires that the compromises in the design, especially between the factors of electrical and mechanical nature and the cost of manufacture, are mainly guided by the mechanical requirements to ensure stability of performance. For example, an antenna about 2 m long operating in a frequency band around 2 GHz has an aluminum frame having a thickness between 1.5 mm and 2.5 mm. Whereas, if only the depth related to the skin effect in the frequency range is taken into account, the required thickness would be only less than 0.1 mm. The presence of metal connections and their positioning between the components make it necessary to choose mechanical solutions such as screwing or welding. These assembly techniques incur additional costs, in particular because of the time required to perform the operation and by the need for a thorough control of the quality of the connection made, and they make disassembly perilous or impossible. Otherwise, because of the inevitable degradation of the electrical contacts, the antenna could be confronted with problems of intermodulation products (IMPs) which translate a distortion of the signals passing through the antenna, such as the loss of performance if these degradations occur where electromagnetic fields are intense.

Les antennes panneaux comportent un réseau d'éléments rayonnants, qui peuvent être des dipôles, fixés sur un châssis métallique qui est un réflecteur plan. Le problème est donc de trouver un dispositif permettant de réaliser le positionnement et la fixation de ces dipôles sur le châssis de manière rapide, fiable, réversible et bon marché afin d'obtenir une liaison qui soit mécaniquement et électriquement efficace et débarrassée des produits d'intermodulation.The panel antennas comprise an array of radiating elements, which may be dipoles, fixed on a metal frame which is a plane reflector. The problem is therefore to find a device for performing the positioning and fixing of these dipoles on the chassis quickly, reliably, reversibly and inexpensively to obtain a connection that is mechanically and electrically effective and rid of the products of intermodulation.

La solution recherchée doit notamment tenir compte simultanément des exigences suivantes :

  • éviter le vissage et/ou la soudure pour effectuer l'assemblage mécanique des dipôles et du réflecteur :
  • réaliser des connexions électriques de type capacitif, c'est-à-dire sans contact direct métal-métal.
In particular, the solution sought must take into account the following requirements:
  • avoid screwing and / or welding to mechanically assemble the dipoles and the reflector:
  • make capacitive type electrical connections, that is to say without direct contact metal-metal.

Le document US 2004/0201537 A1 décrit une antenne de type panneau comportant un dispositif de fixation et de couplage de l'élément rayonnant selon l'art antérieur.The document US 2004/0201537 A1 describes a panel-type antenna comprising a device for fixing and coupling the radiating element according to the prior art.

Le document US-6,933,906 décrit une antenne comprenant un dipôle relié sans contact par voie capacitive à un réflecteur au moyen d'une structure de couplage et de fixation non électriquement conductrice disposée entre le pied de l'élément rayonnant et le réflecteur. La structure de couplage et de fixation est un bouchon en matériau diélectrique. La base du dipôle est insérée et maintenue dans le bouchon muni de reliefs qui est ensuite ancré par rotation dans un orifice de forme et de dimension correspondantes ménagé dans le réflecteur. Pour maintenir le bouchon en place, des moyens de fixation additionnels sont prévus tels que des vis insérées dans un trou du bouchon en plastique et dans un trou du réflecteur en veillant à ne pas établir de connexion électrique avec le dipôle.The document US 6933906 describes an antenna comprising a dipole capacitively coupled to a reflector without capacitor contact by means of a coupling structure and non-electrically conductive fastener disposed between the foot of the radiating element and the reflector. The coupling and fixing structure is a plug of dielectric material. The base of the dipole is inserted and held in the plug provided with reliefs which is then anchored by rotation in an orifice of corresponding shape and size formed in the reflector. To hold the plug in place, additional fastening means are provided such as screws inserted into a hole in the plastic plug and into a hole in the reflector being careful not to make an electrical connection to the dipole.

Cependant cette structure de couplage et de fixation présente l'inconvénient de nécessiter encore l'utilisation de moyens de fixation par vissage pour assurer la fiabilité de la fixation, notamment pour éviter la rotation du bouchon et son désengagement de l'orifice En outre un tel assemblage est pénalisant au point de vue de la surface de couplage En effet la surface importante occupée par l'orifice ménagé dans le réflecteur, de surface au moins égale à celle du bouchon, réduit d'autant la surface de couplage entre le réflecteur et le dipôle.However, this coupling and fixing structure has the disadvantage of still requiring the use of fastening means by screwing to ensure the reliability of the fastening, in particular to prevent rotation of the plug and its disengagement from the orifice. assembly is penalizing from the point of view of the coupling surface Indeed the large surface occupied by the orifice formed in the reflector, surface area at least equal to that of the plug, reduces by the coupling surface between the reflector and the dipole.

La présente invention a pour but d'éliminer les inconvénients de l'art antérieur, et en particulier de proposer un dispositif de couplage et de fixation d'un élément rayonnant sur un support métallique plan de telle sorte que la surface de couplage soit maximisée..The present invention aims to eliminate the disadvantages of the prior art, and in particular to provide a device for coupling and fixing a radiating element on a flat metal support so that the coupling surface is maximized. .

La présente invention a aussi pour but de proposer un dispositif de couplage et de fixation d'un élément rayonnant sur un support métallique plan ne nécessitant pas de recours au vissage ou à la soudure.The present invention also aims to provide a device for coupling and fixing a radiating element on a flat metal support that does not require the use of screwing or welding.

La présente invention a aussi pour but de proposer une antenne comprenant des éléments rayonnants fixés sur un support métallique plan dont l'épaisseur du support est moindre quo dans l'art antérieur sans compromettre la tenue mécanique de l'antenne.The present invention also aims to provide an antenna comprising radiating elements fixed on a flat metal support whose support thickness is less than in the prior art without compromising the mechanical strength of the antenna.

La présente invention a encore pour but de proposer un procédé de couplage et de fixation d'un élément rayonnant sur un support métallique plan qui soit plus rapide et cependant aussi fiable que les procédés antérieurs.The present invention also aims to provide a method of coupling and fixing a radiating element on a flat metal support which is faster and however as reliable as the previous methods.

L'objet de la présente invention est une antenne de type panneau comportant

  • au moins un élément rayonnant comprenant un pied surmonté d'un dipôle,
  • un support conducteur plan muni d'au moins un orifice,
  • un dispositif de couplage et de fixation de l'élément rayonnant comportant une pièce diélectrique comprenant une base et au moins une tige solidaire de la base se projetant dans une direction perpendiculaire au plan de la base, et une couche diélectrique disposée entre l'élément rayonnant et le support pour éviter tout contact direct.
The object of the present invention is a panel type antenna comprising
  • at least one radiating element comprising a foot surmounted by a dipole,
  • a plane conducting support provided with at least one orifice,
  • a device for coupling and fixing the radiating element comprising a dielectric part comprising a base and at least one rod integral with the base projecting in a direction perpendicular to the plane of the base, and a dielectric layer disposed between the radiating element and support to avoid any direct contact.

Le support comporte au moins un orifice dont la dimension est juste nécessaire au passage de la tige de la pièce diélectrique et la base ayant une dimension supérieure à la dimension de l'orifice ménagé dans le support est appliquée sur la face arrière du support.The support comprises at least one orifice whose size is just necessary for the passage of the rod of the dielectric part and the base having a dimension greater than the size of the orifice formed in the support is applied to the rear face of the support.

De préférence, la pièce diélectrique comporte au moins une protubérance, ménagée à l'extrémité de la tige, apte à coopérer avec l'élément rayonnant pour le retenir.Preferably, the dielectric part comprises at least one protuberance, formed at the end of the rod, adapted to cooperate with the radiating element to retain it.

La présence d'une couche diélectrique entre l'élément rayonnant et le support permet de garantir l'isolation électrique, et ainsi de créer un couplage capacitif entre l'élément rayonnant et le réflecteur. La pièce diélectrique, n'ayant plus à assurer celle fonction, peut ainsi être optimisée vis à vis de sa mise en place et de la facilité de fixation de l'élément rayonnant.The presence of a dielectric layer between the radiating element and the support makes it possible to guarantee the electrical insulation, and thus to create a capacitive coupling between the radiating element and the reflector. The dielectric piece, having no longer to ensure that function, can thus be optimized with respect to its implementation and ease of attachment of the radiating element.

Selon un mode de réalisation préféré, la base de la pièce diélectrique comprend à sa périphérie des pétales fléchis adaptés pour permettre un contact ressort avec le support. Le bord périphérique de la base est découpé pour former des pétales qui sont légèrement repliés afin de se projeter hors du plan de la base. Lors de la mise en place de la pièce diélectrique, les pétales viennent les premier en appui sur le support, assurant un effet ressort qui contribue à maintenir l'élément rayonnant dans la position souhaitée.According to a preferred embodiment, the base of the dielectric piece comprises at its periphery bent petals adapted to allow spring contact with the support. The peripheral edge of the base is cut to form petals that are slightly bent to project out of the plane of the base. When placing the dielectric part, the petals come first supported on the support, ensuring a spring effect that helps keep the radiating element in the desired position.

Selon une forme d'exécution, la base de la pièce diélectrique comprend au moins un orifice pour le passage d'un moyen d'alimentation électrique de l'élément rayonnant Ceci permet le passage des moyens d'alimentation sous le support pour dégager la face du support supportant les éléments rayonnants et formant réflecteur. Le support comporte dans ce cas également des orifices pour le passage des moyens d'alimentation.According to one embodiment, the base of the dielectric part comprises at least one orifice for the passage of a power supply means of the radiating element. This allows the passage of the supply means under the support for disengaging the face. support supporting the radiating elements and forming reflector. In this case, the support also includes orifices for the passage of the feed means.

Selon une première variante, la pièce diélectrique comporte au moins une tige apte à coopérer avec l'extérieur du pied de l'élément rayonnant. La tige se projette perpendiculairement à la base de la pièce diélectrique traverse le support par un orifice de taille adaptée. La tige vient se placer le long de l'extérieur du pied de manière à permettre à la protubérance portée par son extrémité de s'ancrer sur une aspérité ménagée à cet effet sur la surface extérieure du pied afin de retenir l'élément rayonnant.According to a first variant, the dielectric part comprises at least one rod capable of cooperating with the outside of the foot of the radiating element. The rod projects perpendicularly to the base of the dielectric piece through the support by a hole of suitable size. The rod is placed along the outside of the foot so as to allow the protrusion carried by its end to anchor on an asperity provided for this purpose on the outer surface of the foot to retain the radiating element.

Selon une deuxième variante, la pièce diélectrique comporte au moins une tige apte à s'insérer à l'intérieur d'un tube creux disposé dans le pied de l'élément rayonnant. La tige se projette perpendiculairement à la base de la pièce diélectrique traverse le support par un orifice de taille adaptée. La tige vient s'insérer dans l'un des tubes creux ménagés dans le pied de l'élément rayonnant de manière à permettre à la protubérance portée par son extrémité de s'ancrer sur une aspérité ménagée à cet effet sur la surface intérieure du tube afin de retenir l'élément rayonnant.According to a second variant, the dielectric part comprises at least one rod capable of being inserted inside a hollow tube disposed in the foot of the radiating element. The rod projects perpendicularly to the base of the dielectric piece through the support by a hole of suitable size. The rod is inserted into one of the hollow tubes formed in the foot of the radiating element so as to allow the protrusion carried by its end to anchor on an asperity provided for this purpose on the inner surface of the tube to retain the radiating element.

Selon encore une forme d'exécution, la protubérance à l'extrémité de la tige a une forme de crochet. Cette forme lui permet de coopérer au mieux avec une aspérité qui peut avoir la forme d'un relief ou d'un logement de forme adaptée à celle du crochet.According to yet another embodiment, the protrusion at the end of the rod has a hook shape. This shape allows it to cooperate best with an asperity that can have the shape of a relief or a shaped housing adapted to that of the hook.

L'invention a pour avantage d'assurer un positionnement exact de l'élément rayonnant par rapport au réflecteur en interdisant sa rotation et de garantir sa fixation en exerçant une force axiale de rétention sur l'élément.The invention has the advantage of ensuring exact positioning of the radiating element with respect to the reflector by prohibiting its rotation and to guarantee its fixation by exerting an axial retention force on the element.

Dans le mode de réalisation de l'invention illustré sur la figure 1, on a représenté un élément rayonnant 1, comportant un pied 2 supportant au moins un dipôle 3, et un réflecteur 4 sur lequel l'élément rayonnant 1 est fixé au moyen d'une pièce diélectrique 5. La pièce diélectrique 5 comprend une base 6 surmontée de tiges 7 portant des reliefs 8 formant crochets, la périphérie de la base 6 étant découpée pour former des pétales 9 légèrement fléchis. La base 6 de la pièce diélectrique 5 est appliquée sur la face arrière 10 du réflecteur 4. Le réflecteur 4 comporte des orifices 11 au travers desquels les tiges 7 sont introduites. Ces orifices 11 ont une dimension juste nécessaire au passage des tiges 7 surmontées de leur relief 8. Dans le cas présent, la partie inférieure du pied 2 de l'élément rayonnant 1 comporte un décrochement 12 constituant une aspérité sur laquelle le relief 8 s'accroche pour retenir l'élément rayonnant 1.In the embodiment of the invention illustrated on the figure 1 , there is shown a radiating element 1 , comprising a base 2 supporting at least one dipole 3 , and a reflector 4 on which the radiating element 1 is fixed by means of a dielectric part 5. The dielectric part 5 comprises a base 6 surmounted by rods 7 bearing reliefs 8 forming hooks, the periphery of the base 6 being cut to form petals 9 slightly bent. The base 6 of the dielectric part 5 is applied to the rear face 10 of the reflector 4. The reflector 4 has orifices 11 through which the rods 7 are introduced. These orifices 11 have a dimension just necessary for the passage of the rods 7 surmounted by their relief 8. In this case, the lower part of the foot 2 of the radiating element 1 comprises a recess 12 constituting an asperity on which the relief 8 s' hangs to hold the radiating element 1 .

La pièce 5 est constituée d'un matériau diélectrique qui lui confère une certaine souplesse, de préférence un polymère comme un polyoxyméthylène (POM), un polyoxyméthylène (POM) renforcé de fibres de verre, un polyéthylène (PE), un polystyrène (PS), un acrylonitrile/butadiène/styrène (ABS), un copolymère acrylonitrile/styrène/acrylate (ASA), etc.... La périphéne de la base 6 est découpée de manière à former des pétales 9 légèrement fléchis qui sont relativement plus flexibles que la partie centrale 13 de la base 6. La base 6 se trouve ainsi en appui élastique sur la face arrière 10 du réflecteur 4 par l'intermédiaire de ses pétales 9. Cet appui élastique exerce une force sur le crochet 8 qui assure le maintien do l'élément rayonnant 1 par effet ressort. Une fois en place, l'élément rayonnant 1 est fermement maintenu et l'assemblage ne nécessite aucun moyen de fixation supplémentaire. Une couche isolante 14 est intercalé entre la partie inférieure du pied 2 de l'élément rayonnant 1 et la face avant 15 du réflecteur 4 afin d'éviter tout contact direct et ainsi créer un couplage capacitif entre l'élément rayonnant 1 et le réflecteur 4. La couche diélectrique 14 est par exemple une film mince isolante en polyéthylène (PE) ayant une épaisseur de l'ordre de 0,1 mm. On utilisera de préférence un film coloré pour faciliter les contrôles.The part 5 consists of a dielectric material which gives it a certain flexibility, preferably a polymer such as a polyoxymethylene (POM), a polyoxymethylene (POM) reinforced with glass fibers, a polyethylene (PE), a polystyrene (PS) , an acrylonitrile / butadiene / styrene (ABS), an acrylonitrile / styrene / acrylate copolymer (ASA), etc. The periphery of the base 6 is cut to form slightly bent petals 9 which are relatively more flexible than the central portion 13 of the base 6. The base 6 is thus resiliently supported on the rear face 10 of the reflector 4 by means of its petals 9. This elastic support exerts a force on the hook 8 which ensures the maintenance of the radiating element 1 by spring effect. Once in place, the radiating element 1 is firmly held and the assembly requires no additional fastening means. An insulating layer 14 is interposed between the lower part of the foot 2 of the radiating element 1 and the front face 15 of the reflector 4 in order to avoid any direct contact and thus to create a capacitive coupling between the radiating element 1 and the reflector 4 . the dielectric layer 14 is for example an insulating thin film of polyethylene (PE) having a thickness of about 0.1 mm. A colored film will preferably be used to facilitate the controls.

Le pied 2 de l'élément rayonnant 1 comporte le plus souvent quatre tubes creux 20 juxtaposés destinés au passage des fils conducteurs 16 d'alimentation électrique des dipôles 3. Dans le mode de réalisation illustré sur la figure 2, deux tubes 20 inutilisés pour l'alimentation du dipôle 3 sont disponibles pour recevoir des tiges 21 portant une protubérance 22 appartenant à une pièce diélectrique 23. La pièce diélectrique 23 comprend une base 24 surmontée de tiges 21 portant des protubérances 22 formant crochets. Les tiges 21 sont disposées de manière plus centrale sur la base 24 que dans le cas précédent de manière à correspondre à l'emplacement des tubes 20 dans lesquels elles s'insèrent. Un décrochement 25 a été ménagé sur la face interne des tubes 20 de manière à former une aspérité sur laquelle la protubérance 22 peut venir s'accrocher.The foot 2 of the radiating element 1 most often comprises four juxtaposed hollow tubes 20 intended for the passage of the electrical power supply wires 16 of the dipoles 3. In the embodiment illustrated in FIG. figure 2 Two unused tubes 20 for feeding the dipole 3 are available for receiving the rods 21 carrying a protuberance 22 belonging to a dielectric member 23. The dielectric member 23 includes a base 24 surmounted rods 21 carrying the protuberances 22 hook. The rods 21 are arranged more centrally on the base 24 than in the previous case so as to correspond to the location of the tubes 20 into which they fit. A recess 25 has been formed on the inner face of the tubes 20 so as to form an asperity on which the protrusion 22 can come hang.

On considérera maintenant la figure 3 qui Illustre un mode de réalisation avantageux du dispositif de fixation selon la présente invention. Dans ce mode de réalisation, un élément rayonnant 1, comportant un pied 2 et au moins un dipôle 3, est fixé sur un réflecteur plan 4 au moyen d'une pièce diélectrique 30. We will now consider the figure 3 which illustrates an advantageous embodiment of the fixing device according to the present invention. In this embodiment, a radiating element 1 comprising a foot 2 and at least one dipole 3 is fixed on a flat reflector 4 by means of a dielectric part 30.

La pièce diélectrique 30 est représentée vue en perspective sur la figure 4 et vue de dessus sur la figure 5. La pièce diélectrique 30 comporte une base 31 d'où partent au moins une tige centrale 32, deux dans le cas présent, et au moins une tige périphérique 33, quatre dans le cas présent. La tige périphérique 33 est munie d'une extrémité formant crochet 34 qui coopère avec un relief 35 aménagé sur le pied 2 de l'élément rayonnant. Les tiges 33 traverse le réflecteur plan par des orifices 11 dimensionnés au plus juste pour permettre le passage. La tige centrale 32 porte un double crochet 36 à son extrémité. La tige centrale 32 s'insère dans l'un des tubes creux 20 de l'élément rayonnant 1, qui n'est pas occupé par un conducteur d'alimentation 16. Le crochet 36 coopère avec des logements 37 ménagés dans la face interne du tube 20 The dielectric piece 30 is shown in perspective view on the figure 4 and top view on the figure 5 . The dielectric part 30 comprises a base 31 from which at least one central rod 32, two in the present case, and at least one peripheral rod 33, four in this case. The peripheral rod 33 is provided with a hook end 34 which cooperates with a relief 35 arranged on the foot 2 of the radiating element. The rods 33 passes through the plane reflector through orifices 11 dimensioned at most just to allow passage. The central rod 32 carries a double hook 36 at its end. The central rod 32 is inserted into one of the hollow tubes 20 of the radiating element 1, which is not occupied by a supply conductor 16 . The hook 36 cooperates with housings 37 formed in the inner face of the tube 20

L'assemblage s'effectue en commençant par la mise en place de la pièce diélectrique 30 par la face arriére 10 du réflecteur 4. Les tiges 32, 33 sont introduites dans les orifices 11 du réflecteur 4. La basa 31 est plaquée contre la face arrière 10 du réflecteur 4, la périphérie de la base 31 étant découpée de manière à former des pétales 38 qui s'appuient élastiquement contre la face 10. Un film isolant 14 est déposé sur la face avant 15 du réflecteur 4. Le pied 2 de l'élément rayonnant 1 est alors enfoncé axialement sur la pièce diélectrique 30 de manière à ce que les tiges 32 s'insèrent dans les tubes 20 du pied 2 de l'élément rayonnant, et que les tiges 33 se mettent en place autour du pied 2. Une pression finale permet d'encliqueter les crochets 34, 36 sur les aspérités 35, 37 extérieures ou inférieures du pied 2 afin de retenir l'élément rayonnant 1. L'élément rayonnant 1 se trouve ainsi en appui sur la face avant 15 du réflecteur 4 par l'intermédiaire du film isolant 14 qui interdit tout contact direct entre l'élément rayonnant 1 et le réflecteur 4. The assembly is carried out starting with the introduction of the dielectric part 30 by the rear face 10 of the reflector 4. The rods 32, 33 are introduced into the orifices 11 of the reflector 4. The base 31 is pressed against the face rear 10 of the reflector 4, the periphery of the base 31 being cut so as to form petals 38 which bear elastically against the face 10. An insulating film 14 is deposited on the front face 15 of the reflector 4. The foot 2 of the radiating element 1 is then pressed axially on the dielectric part 30 so that the rods 32 fit into the tubes 20 of the foot 2 of the radiating element, and that the rods 33 are set up around the foot 2. A final pressure makes it possible to snap the hooks 34, 36 on the outer, or lower asperities 35, 37 of the foot 2 in order to retain the radiating element 1 . The radiating element 1 is thus supported on the front face 15 of the reflector 4 by means of the insulating film 14 which prevents any direct contact between the radiating element 1 and the reflector 4.

Une antenne 60 assemblée selon le procédé qui vient d'être décrit est représentée en perspective sur la figure 6. L'antenne 60 comporte des éléments rayonnants 61 alignés et fixés sur un réflecteur 62 au moyen d'une pièce diélectrique 63 analogue à celle décrite précédemment.An antenna 60 assembled according to the method which has just been described is represented in perspective on the figure 6 . The antenna 60 comprises radiating elements 61 aligned and fixed on a reflector 62 by means of a dielectric piece 63 similar to that described above.

La face inférieure 64 du réflecteur 62 de l'antenne 60 est représentée sur la figure 7. On y voit la base 65 de la pièce diélectrique 63 s'appuyant de manière élastique sur la face inférieure 64 du réflecteur 62 par l'intermédiaire des pétales 66 découpés à sa périphérie et légèrement pliés. Ces pétales 66 servent de ressort pour exercer une force de traction sur les protubérances portées par l'extrémité des tiges accrochées aux aspérités du pied de l'élément rayonnant 61. Une force adaptée est exercée sur les éléments rayonnants 61 qui sont ainsi retenus de manière efficace et fiable et ils sont protégés d'un déplacement dû à des chocs ou des vibrations.The lower face 64 of the reflector 62 of the antenna 60 is represented on the figure 7 . It shows the base 65 of the dielectric part 63 resiliently supported on the underside 64 of the reflector 62 via the petals 66 cut at its periphery and slightly bent. These petals 66 serve as a spring for exerting a traction force on the protuberances carried by the end of the rods attached to the asperities of the foot of the radiating element 61. A suitable force is exerted on the radiating elements 61 which are thus retained efficient and reliable and they are protected from shifting due to shocks or vibrations.

Sur la face inférieure 64, des raidisseurs 67 ont été installés. Les raidisseurs 67 sont fixés sur les bords longitudinaux 68 repliés opposés de la face inférieure 64 du réflecteur 62 sur lesquels ils exercent une pression modérée de manière à empêcher le rapprochement des bords 68. Le raidisseur 67 comporte une base 69 dont ta forme épouse celle du réflecteur 62 et une crête 70 qui se dresse sur la base 69 et contribue à la rigidité du raidisseur 67. Ces raidisseurs 67 sont en un matériau rigide, de préférence diélectrique, tel qu'un polymère comme un polyoxyméthylène (POM), un polyuxyméthylène (POM) renforcé de fibres de verre, un polyéthylène (PE), un polystyrène (PS), un acrylonitrile/butadiène/styrène (ABS), un copolymére acrylonitrile/styrène/acrylate (ASA). etc....On the lower face 64, stiffeners 67 have been installed. The stiffeners 67 are fixed on the opposite folded longitudinal edges 68 of the lower face 64 of the reflector 62 on which they exert a moderate pressure so as to prevent the edges 68 from coming together . The stiffener 67 comprises a base 69 whose shape matches that of the reflector 62 and a peak 70 which stands on the base 69 and contributes to the rigidity of the stiffener 67. These stiffeners 67 are made of a rigid material, preferably dielectric, such as a polymer such as a polyoxymethylene (POM), a polyuxymethylene ( POM) reinforced with glass fibers, a polyethylene (PE), a polystyrene (PS), acrylonitrile / butadiene / styrene (ABS), acrylonitrile / styrene / acrylate copolymer (ASA). etc ....

La figure 8 montre un autre mode de réalisation d'un raidisseur 80 placé sur la face supérieure d'un réflecteur 81 supportant des éléments rayonnants 82. Les raidisseurs 80 sont disposé entre les éléments rayonnants 82. Ces raidisseurs 80 ont une forme d'arcs de cercle et s'appuient sur les bords longitudinaux 83 du réflecteur 81. The figure 8 shows another embodiment of a stiffener 80 placed on the upper face of a reflector 81 supporting radiating elements 82. The stiffeners 80 are disposed between the radiating elements 82. These stiffeners 80 have a shape of arcs of circle and rely on the longitudinal edges 83 of the reflector 81.
